+Before building the Qt library, the Qt SQL module can be enabled for
+specific databases using 'configure'. 'configure' is located at the
+top of your QTDIR.
+
+Specific databases drivers can be enabled using one of the following
+options:
+
+ ./configure [-qt-sql-<driver>] [-plugin-sql-<driver>]
+
+or disabled using the following option:
+
+ ./configure [-no-sql-<driver>]
+
+Where <driver> is the name of the driver, for example 'psql'. This
+will configure the Qt library to compile the specified driver into
+the Qt lib itself.
+
+For example, to build the PostgreSQL driver directly into the Qt
+library, configure Qt like this:
+
+ ./configure -qt-sql-psql
+
+In addition, you may need to specify an extra include path, as some
+database drivers require headers for the database they are using,
+for example:
+
+ ./configure -qt-sql-psql -I/usr/local/include
+
+If instead you need to build the PostgreSQL driver as a dynamically
+loaded plugin, configure Qt like this:
+
+ ./configure -plugin-sql-psql
+
+To compile drivers as dynamically loaded plugins, see the
+QTDIR/plugins/src/sqldrivers directory. Use 'configure -help'
+for a complete list of configure options. See the Qt documentation
+for a complete list of supported database drivers.

+/*!
+ \class TQDataBrowser tqdatabrowser.h
+ \brief The TQDataBrowser class provides data manipulation and
+ navigation for data entry forms.
+
+ \ingroup database
+ \mainclass
+ \module sql
+
+ A high-level API is provided for navigating through data records
+ in a cursor, for inserting, updating and deleting records, and for
+ refreshing data in the display.
+
+ If you want a read-only form to present database data use
+ TQDataView; if you want a table-based presentation of your data use
+ TQDataTable.
+
+ A TQDataBrowser is used to associate a dataset with a form in much
+ the same way as a TQDataTable associates a dataset with a table.
+ Once the data browser has been constructed it can be associated
+ with a dataset with setSqlCursor(), and with a form with
+ setForm(). Boundary checking, sorting and filtering can be set
+ with setBoundaryChecking(), setSort() and setFilter(),
+ respectively.
+
+ The insertCurrent() function reads the fields from the default
+ form into the default cursor and performs the insert. The
+ updateCurrent() and deleteCurrent() functions perform similarly to
+ update and delete the current record respectively.
+
+ The user can be asked to confirm all edits with setConfirmEdits().
+ For more precise control use setConfirmInsert(),
+ setConfirmUpdate(), setConfirmDelete() and setConfirmCancels().
+ Use setAutoEdit() to control the behaviour of the form when the
+ user edits a record and then navigates.
+
+ The record set is navigated using first(), next(), prev(), last()
+ and seek(). The form's display is updated with refresh(). When
+ navigation takes place the firstRecordAvailable(),
+ lastRecordAvailable(), nextRecordAvailable() and
+ prevRecordAvailable() Q_SIGNALS are emitted. When the cursor record
+ is changed due to navigation the cursorChanged() signal is
+ emitted.
+
+ If you want finer control of the insert, update and delete
+ processes then you can use the lower level functions to perform
+ these operations as described below.
+
+ The form is populated with data from the database with
+ readFields(). If the user is allowed to edit, (see setReadOnly()),
+ write the form's data back to the cursor's edit buffer with
+ writeFields(). You can clear the values in the form with
+ clearValues(). Editing is performed as follows:
+ \list
+ \i \e insert When the data browser enters insertion mode it emits the
+ primeInsert() signal which you can connect to, for example to
+ pre-populate fields. Call writeFields() to write the user's edits to
+ the cursor's edit buffer then call insert() to insert the record
+ into the database. The beforeInsert() signal is emitted just before
+ the cursor's edit buffer is inserted into the database; connect to
+ this for example, to populate fields such as an auto-generated
+ primary key.
+ \i \e update For updates the primeUpdate() signal is emitted when
+ the data browser enters update mode. After calling writeFields()
+ call update() to update the record and connect to the beforeUpdate()
+ signal to manipulate the user's data before the update takes place.
+ \i \e delete For deletion the primeDelete() signal is emitted when
+ the data browser enters deletion mode. After calling writeFields()
+ call del() to delete the record and connect to the beforeDelete()
+ signal, for example to record an audit of the deleted record.
+ \endlist

+ \class TQDataTable tqdatatable.h
+ \brief The TQDataTable class provides a flexible SQL table widget that supports browsing and editing.
+
+ \ingroup database
+ \mainclass
+ \module sql
+
+ TQDataTable supports various functions for presenting and editing
+ SQL data from a \l TQSqlCursor in a table.
+
+ If you want a to present your data in a form use TQDataBrowser, or
+ for read-only forms, TQDataView.
+
+ When displaying data, TQDataTable only retrieves data for visible
+ rows. If the driver supports the 'query size' property the
+ TQDataTable will have the correct number of rows and the vertical
+ scrollbar will accurately reflect the number of rows displayed in
+ proportion to the number of rows in the dataset. If the driver
+ does not support the 'query size' property, rows are dynamically
+ fetched from the database on an as-needed basis with the scrollbar
+ becoming more accurate as the user scrolls down through the
+ records. This allows extremely large queries to be displayed as
+ quickly as possible, with minimum memory usage.
+
+ TQDataTable inherits TQTable's API and extends it with functions to
+ sort and filter the data and sort columns. See setSqlCursor(),
+ setFilter(), setSort(), setSorting(), sortColumn() and refresh().
+
+ When displaying editable cursors, cell editing will be enabled.
+ (For more information on editable cursors, see \l TQSqlCursor).
+ TQDataTable can be used to modify existing data and to add new
+ records. When a user makes changes to a field in the table, the
+ cursor's edit buffer is used. The table will not send changes in
+ the edit buffer to the database until the user moves to a
+ different record in the grid or presses Enter. Cell editing is
+ initiated by pressing F2 (or right clicking and then clicking the
+ appropriate popup menu item) and canceled by pressing Esc. If
+ there is a problem updating or adding data, errors are handled
+ automatically (see handleError() to change this behavior). Note
+ that if autoEdit() is FALSE navigating to another record will
+ cancel the insert or update.
+
+ The user can be asked to confirm all edits with setConfirmEdits().
+ For more precise control use setConfirmInsert(),
+ setConfirmUpdate(), setConfirmDelete() and setConfirmCancels().
+ Use setAutoEdit() to control the behaviour of the table when the
+ user edits a record and then navigates. (Note that setAutoDelete()
+ is unrelated; it is used to set whether the TQSqlCursor is deleted
+ when the table is deleted.)
+
+ Since the data table can perform edits, it must be able to
+ uniquely identify every record so that edits are correctly
+ applied. Because of this the underlying cursor must have a valid
+ primary index to ensure that a unique record is inserted, updated
+ or deleted within the database otherwise the database may be
+ changed to an inconsistent state.
+
+ TQDataTable creates editors using the default \l TQSqlEditorFactory.
+ Different editor factories can be used by calling
+ installEditorFactory(). A property map is used to map between the
+ cell's value and the editor. You can use your own property map
+ with installPropertyMap().
+
+ The contents of a cell is available as a TQString with text() or as
+ a TQVariant with value(). The current record is returned by
+ currentRecord(). Use the tqfind() function to search for a string in
+ the table.
+
+ Editing actions can be applied programatically. For example, the
+ insertCurrent() function reads the fields from the current record
+ into the cursor and performs the insert. The updateCurrent() and
+ deleteCurrent() functions perform similarly to update and delete
+ the current record respectively.
+
+ Columns in the table can be created automatically based on the
+ cursor (see setSqlCursor()). Columns can be manipulated manually
+ using addColumn(), removeColumn() and setColumn().
+
+ The table automatically copies many of the properties of the
+ cursor to format the display of data within cells (tqalignment,
+ visibility, etc.). The cursor can be changed with setSqlCursor().
+ The filter (see setFilter()) and sort defined within the table are
+ used instead of the filter and sort set on the cursor. For sorting
+ options see setSort(), sortColumn(), sortAscending() and
+ sortDescending(). Note that sorting operations will not behave as
+ expected if you are using a TQSqlSelectCursor because it uses
+ user-defined SQL queries to obtain data.
+
+ The text used to represent NULL, TRUE and FALSE values can be
+ changed with setNullText(), setTrueText() and setFalseText()
+ respectively. You can change the appearance of cells by
+ reimplementing paintField().
+
+ Whenever a new row is selected in the table the currentChanged()
+ signal is emitted. The primeInsert() signal is emitted when an
+ insert is initiated. The primeUpdate() and primeDelete() Q_SIGNALS
+ are emitted when update and deletion are initiated respectively.
+ Just before the database is updated a signal is emitted;
+ beforeInsert(), beforeUpdate() or beforeDelete() as appropriate.

+ \class TQSqlCursor tqsqlcursor.h
+ \brief The TQSqlCursor class provides browsing and editing of SQL
+ tables and views.
+
+ \ingroup database
+ \module sql
+
+ A TQSqlCursor is a database record (see \l TQSqlRecord) that
+ corresponds to a table or view within an SQL database (see \l
+ TQSqlDatabase). There are two buffers in a cursor, one used for
+ browsing and one used for editing records. Each buffer tqcontains a
+ list of fields which correspond to the fields in the table or
+ view.
+
+ When positioned on a valid record, the browse buffer tqcontains the
+ values of the current record's fields from the database. The edit
+ buffer is separate, and is used for editing existing records and
+ inserting new records.
+
+ For browsing data, a cursor must first select() data from the
+ database. After a successful select() the cursor is active
+ (isActive() returns TRUE), but is initially not positioned on a
+ valid record (isValid() returns FALSE). To position the cursor on
+ a valid record, use one of the navigation functions, next(),
+ prev(), first(), last(), or seek(). Once positioned on a valid
+ record, data can be retrieved from the browse buffer using
+ value(). If a navigation function is not successful, it returns
+ FALSE, the cursor will no longer be positioned on a valid record
+ and the values returned by value() are undefined.
+
+ For example:
+
+ \quotefile sql/overview/retrieve2/main.cpp
+ \skipto TQSqlCursor
+ \printline TQSqlCursor
+ \printuntil }
+
+ In the above example, a cursor is created specifying a table or
+ view name in the database. Then, select() is called, which can be
+ optionally parameterised to filter and order the records
+ retrieved. Each record in the cursor is retrieved using next().
+ When next() returns FALSE, there are no more records to process,
+ and the loop terminates.
+
+ For editing records (rows of data), a cursor tqcontains a separate
+ edit buffer which is independent of the fields used when browsing.
+ The functions insert(), update() and del() operate on the edit
+ buffer. This allows the cursor to be repositioned to other
+ records while simultaneously maintaining a separate buffer for
+ edits. You can get a pointer to the edit buffer using
+ editBuffer(). The primeInsert(), primeUpdate() and primeDelete()
+ functions also return a pointer to the edit buffer and prepare it
+ for insert, update and delete respectively. Edit operations only
+ affect a single row at a time. Note that update() and del()
+ require that the table or view contain a primaryIndex() to ensure
+ that edit operations affect a unique record within the database.
+
+ For example:
+
+ \quotefile sql/overview/update/main.cpp
+ \skipto prices
+ \printline prices
+ \printuntil update
+ \printline
+
+ To edit an existing database record, first move to the record you
+ wish to update. Call primeUpdate() to get the pointer to the
+ cursor's edit buffer. Then use this pointer to modify the values
+ in the edit buffer. Finally, call update() to save the changes to
+ the database. The values in the edit buffer will be used to
+ locate the appropriate record when updating the database (see
+ primaryIndex()).
+
+ Similarly, when deleting an existing database record, first move
+ to the record you wish to delete. Then, call primeDelete() to get
+ the pointer to the edit buffer. Finally, call del() to delete the
+ record from the database. Again, the values in the edit buffer
+ will be used to locate and delete the appropriate record.
+
+ To insert a new record, call primeInsert() to get the pointer to
+ the edit buffer. Use this pointer to populate the edit buffer
+ with new values and then insert() the record into the database.
+
+ After calling insert(), update() or del(), the cursor is no longer
+ positioned on a valid record and can no longer be navigated
+ (isValid() return FALSE). The reason for this is that any changes
+ made to the database will not be visible until select() is called
+ to refresh the cursor. You can change this behavior by passing
+ FALSE to insert(), update() or del() which will prevent the cursor
+ from becoming invalid. The edits will still not be visible when
+ navigating the cursor until select() is called.
+
+ TQSqlCursor tqcontains virtual methods which allow editing behavior
+ to be customized by subclasses. This allows custom cursors to be
+ created that encapsulate the editing behavior of a database table
+ for an entire application. For example, a cursor can be customized
+ to always auto-number primary index fields, or provide fields with
+ suitable default values, when inserting new records. TQSqlCursor
+ generates SQL statements which are sent to the database engine;
+ you can control which fields are included in these statements
+ using setGenerated().
+
+ Note that TQSqlCursor does not inherit from TQObject. This means
+ that you are responsible for destroying instances of this class
+ yourself. However if you create a TQSqlCursor and use it in a
+ \l TQDataTable, \l TQDataBrowser or a \l TQDataView these classes will
+ usually take ownership of the cursor and destroy it when they
+ don't need it anymore. The documentation for TQDataTable,
+ TQDataBrowser and TQDataView explicitly states which calls take
+ ownership of the cursor.

+
+ The TQSqlDatabase class provides an abstract interface for

+ for executing and manipulating SQL queries (see TQSqlQuery).

+/*! \overload
+
+ This function is useful if you need to set up the database
+ connection and instantiate the driver yourself. If you do this, it
+ is recommended that you include the driver code in your own
+ application. For example, setting up a custom PostgreSQL
+ connection and instantiating the TQPSQL7 driver can be done the
+ following way:
+
+ \code
+ #include "tqtdir/src/sql/drivers/psql/qsql_psql.cpp"
+ \endcode
+ (We assume that \c qtdir is the directory where TQt is installed.)
+ This will pull in the code that is needed to use the PostgreSQL
+ client library and to instantiate a TQPSTQLDriver object, assuming
+ that you have the PostgreSQL headers somewhere in your include
+ search path.
+
+ \code
+ PGconn* con = PQconnectdb( "host=server user=bart password=simpson dbname=springfield" );
+ TQPSTQLDriver* drv = new TQPSTQLDriver( con );
+ TQSqlDatabase* db = TQSqlDatabase::addDatabase( drv ); // becomes the new default connection
+ TQSqlQuery q;
+ q.exec( "SELECT * FROM people" );
+ ...
+ \endcode
+
+ The above code sets up a PostgreSQL connection and instantiates a
+ TQPSTQLDriver object. Next, addDatabase() is called to add the
+ connection to the known connections so that it can be used by the
+ TQt SQL classes. When a driver is instantiated with a connection
+ handle (or set of handles), TQt assumes that you have already
+ opened the database connection.
+
+ Remember that you must link your application against the database
+ client library as well. The simplest way to do this is to add
+ lines like those below to your \c .pro file:
+
+ \code
+ unix:LIBS += -lpq
+ win32:LIBS += libpqdll.lib
+ \endcode
+
+ You will need to have the client library in your linker's search
+ path.
+
+ The method described above will work for all the drivers, the only
+ difference is the arguments the driver constructors take. Below is
+ an overview of the drivers and their constructor arguments.
+
+ \table
+ \header \i Driver \i Class name \i Constructor arguments \i File to include
+ \row
+ \i TQPSQL7
+ \i TQPSTQLDriver
+ \i PGconn* connection
+ \i \c qsql_psql.cpp
+ \row
+ \i TQMYSQL3
+ \i TQMYSTQLDriver
+ \i MYSQL* connection
+ \i \c qsql_mysql.cpp
+ \row
+ \i TQOCI8
+ \i TQOCIDriver
+ \i OCIEnv* environment, OCIError* error, OCISvcCtx* serviceContext
+ \i \c qsql_oci.cpp
+ \row
+ \i TQODBC3
+ \i TQODBCDriver
+ \i STQLHANDLE environment, STQLHANDLE connection
+ \i \c qsql_odbc.cpp
+ \row
+ \i TQDB2
+ \i TQDB2
+ \i STQLHANDLE environment, STQLHANDLE connection

+ \i isc_db_handle connection
+ \i \c qsql_ibase.cpp
+ \endtable
+
+ Note: The host name (or service name) is needed when constructing
+ the TQTDSDriver for creating new connections for internal
+ queries. This is to prevent the simultaneous usage of several
+ TQSqlQuery/\l{TQSqlCursor} objects from blocking each other.
+

+ easy to create your own SQL driver plugins that can be loaded
+ dynamically by TQt.
+
+ Writing a SQL plugin is achieved by subclassing this base class,
+ reimplementing the pure virtual functions keys() and create(), and
+ exporting the class with the \c TQ_EXPORT_PLUGIN macro. See the SQL
+ plugins that come with TQt for example implementations (in the
+ \c{plugins/src/sqldrivers} subdirectory of the source
+ distribution). Read the \link plugins-howto.html plugins
+ documentation\endlink for more information on plugins.

+/*!
+ \class TQSqlField tqsqlfield.h
+ \brief The TQSqlField class manipulates the fields in SQL database tables
+ and views.
+
+ \ingroup database
+ \module sql
+
+ TQSqlField represents the characteristics of a single column in a
+ database table or view, such as the data type and column name. A
+ field also tqcontains the value of the database column, which can be
+ viewed or changed.
+
+ Field data values are stored as TQVariants. Using an incompatible
+ type is not permitted. For example:
+
+ \code
+ TQSqlField f( "myfield", TQVariant::Int );
+ f.setValue( TQPixmap() ); // will not work
+ \endcode
+
+ However, the field will attempt to cast certain data types to the
+ field data type where possible:
+
+ \code
+ TQSqlField f( "myfield", TQVariant::Int );
+ f.setValue( TQString("123") ); // casts TQString to int
+ \endcode
+
+ TQSqlField objects are rarely created explicitly in application
+ code. They are usually accessed indirectly through \l TQSqlRecord
+ or \l TQSqlCursor which already contain a list of fields. For
+ example:
+
+ \code
+ TQSqlCursor cur( "Employee" ); // create cursor using the 'Employee' table
+ TQSqlField* f = cur.field( "name" ); // use the 'name' field
+ f->setValue( "Dave" ); // set field value
+ ...
+ \endcode
+
+ In practice we rarely need to extract a pointer to a field at all.
+ The previous example would normally be written:
+
+ \code
+ TQSqlCursor cur( "Employee" );
+ cur.setValue( "name", "Dave" );
+ ...

+ \class TQSqlForm
+ \brief The TQSqlForm class creates and manages data entry forms
+ tied to SQL databases.
+
+ \ingroup database
+ \mainclass
+ \module sql
+
+ Typical use of a TQSqlForm consists of the following steps:
+ \list
+ \i Create the widgets you want to appear in the form.
+ \i Create a cursor and navigate to the record to be edited.
+ \i Create the TQSqlForm.
+ \i Set the form's record buffer to the cursor's update buffer.
+ \i Insert each widget and the field it is to edit into the form.
+ \i Use readFields() to update the editor widgets with values from
+ the database's fields.
+ \i Display the form and let the user edit values etc.
+ \i Use writeFields() to update the database's field values with
+ the values in the editor widgets.
+ \endlist
+
+ Note that a TQSqlForm does not access the database directly, but
+ most often via TQSqlFields which are part of a TQSqlCursor. A
+ TQSqlCursor::insert(), TQSqlCursor::update() or TQSqlCursor::del()
+ call is needed to actually write values to the database.
+
+ Some sample code to initialize a form successfully:
+
+ \code
+ TQLineEdit myEditor( this );
+ TQSqlForm myForm( this );
+ TQSqlCursor myCursor( "mytable" );
+
+ // Execute a query to make the cursor valid
+ myCursor.select();
+ // Move the cursor to a valid record (the first record)
+ myCursor.next();
+ // Set the form's record pointer to the cursor's edit buffer (which
+ // tqcontains the current record's values)
+ myForm.setRecord( myCursor.primeUpdate() );
+
+ // Insert a field into the form that uses myEditor to edit the
+ // field 'somefield' in 'mytable'
+ myForm.insert( &myEditor, "somefield" );
+
+ // Update myEditor with the value from the mapped database field
+ myForm.readFields();
+ ...
+ // Let the user edit the form
+ ...
+ // Update the database
+ myForm.writeFields(); // Update the cursor's edit buffer from the form
+ myCursor.update(); // Update the database from the cursor's buffer
+ \endcode
+
+ If you want to use custom editors for displaying and editing data
+ fields, you must install a custom TQSqlPropertyMap. The form
+ uses this object to get or set the value of a widget.
+
+ Note that \link designer-manual.book TQt Designer\endlink provides
+ a visual means of creating data-aware forms.

+ \class TQSqlPropertyMap tqsqlpropertymap.h
+ \brief The TQSqlPropertyMap class is used to map widgets to SQL fields.
+
+ \ingroup database
+ \module sql
+
+ The SQL module uses TQt \link properties.html object
+ properties\endlink to insert and extract values from editor
+ widgets.
+
+ This class is used to map editors to SQL fields. This works by
+ associating SQL editor class names to the properties used to
+ insert and extract values to/from the editor.
+
+ For example, a TQLineEdit can be used to edit text strings and
+ other data types in TQDataTables or TQSqlForms. Several properties
+ are defined in TQLineEdit, but only the \e text property is used to
+ insert and extract text from a TQLineEdit. Both TQDataTable and
+ TQSqlForm use the global TQSqlPropertyMap for inserting and
+ extracting values to and from an editor widget. The global
+ property map defines several common widgets and properties that
+ are suitable for many applications. You can add and remove widget
+ properties to suit your specific needs.
+
+ If you want to use custom editors with your TQDataTable or
+ TQSqlForm, you must install your own TQSqlPropertyMap for that table
+ or form. Example:
+
+ \code
+ TQSqlPropertyMap *myMap = new TQSqlPropertyMap();
+ TQSqlForm *myForm = new TQSqlForm( this );
+ MyEditor myEditor( this );
+
+ // Set the TQSqlForm's record buffer to the update buffer of
+ // a pre-existing TQSqlCursor called 'cur'.
+ myForm->setRecord( cur->primeUpdate() );
+
+ // Install the customized map
+ myMap->insert( "MyEditor", "content" );
+ myForm->installPropertyMap( myMap ); // myForm now owns myMap
+ ...
+ // Insert a field into the form that uses a myEditor to edit the
+ // field 'somefield'
+ myForm->insert( &myEditor, "somefield" );
+
+ // Update myEditor with the value from the mapped database field
+ myForm->readFields();
+ ...
+ // Let the user edit the form
+ ...
+ // Update the database fields with the values in the form
+ myForm->writeFields();
+ ...
+ \endcode
+
+ You can also tqreplace the global TQSqlPropertyMap that is used by
+ default. (Bear in mind that TQSqlPropertyMap takes ownership of the
+ new default map.)
+
+ \code
+ TQSqlPropertyMap *myMap = new TQSqlPropertyMap;
+
+ myMap->insert( "MyEditor", "content" );
+ TQSqlPropertyMap::installDefaultMap( myMap );
+ ...
+ \endcode

+ \class TQSqlQuery tqsqlquery.h
+ \brief The TQSqlQuery class provides a means of executing and
+ manipulating SQL statements.
+
+ \ingroup database
+ \mainclass
+ \module sql
+
+ TQSqlQuery encapsulates the functionality involved in creating,
+ navigating and retrieving data from SQL queries which are executed
+ on a \l TQSqlDatabase. It can be used to execute DML (data
+ manipulation language) statements, e.g. \c SELECT, \c INSERT, \c
+ UPDATE and \c DELETE, and also DDL (data definition language)
+ statements, e.g. \c{CREATE TABLE}. It can also be used to
+ execute database-specific commands which are not standard SQL
+ (e.g. \c{SET DATESTYLE=ISO} for PostgreSQL).
+
+ Successfully executed SQL statements set the query's state to
+ active (isActive() returns TRUE); otherwise the query's state is
+ set to inactive. In either case, when executing a new SQL
+ statement, the query is positioned on an invalid record; an active
+ query must be navigated to a valid record (so that isValid()
+ returns TRUE) before values can be retrieved.
+
+ Navigating records is performed with the following functions:
+
+ \list
+ \i \c next()
+ \i \c prev()
+ \i \c first()
+ \i \c last()
+ \i \c \link TQSqlQuery::seek() seek\endlink(int)
+ \endlist
+
+ These functions allow the programmer to move forward, backward or
+ arbitrarily through the records returned by the query. If you only
+ need to move forward through the results, e.g. using next() or
+ using seek() with a positive offset, you can use setForwardOnly()
+ and save a significant amount of memory overhead. Once an active
+ query is positioned on a valid record, data can be retrieved using
+ value(). All data is transferred from the SQL backend using
+ TQVariants.
+
+ For example:
+
+ \code
+ TQSqlQuery query( "SELECT name FROM customer" );
+ while ( query.next() ) {
+ TQString name = query.value(0).toString();
+ doSomething( name );
+ }
+ \endcode
+
+ To access the data returned by a query, use the value() method.
+ Each field in the data returned by a SELECT statement is accessed
+ by passing the field's position in the statement, starting from 0.
+ Information about the fields can be obtained via TQSqlDatabase::record().
+ For the sake of efficiency there are no functions to access a field
+ by name. (The \l TQSqlCursor class provides a higher-level interface
+ with field access by name and automatic SQL generation.)
+
+ TQSqlQuery supports prepared query execution and the binding of
+ parameter values to placeholders. Some databases don't support
+ these features, so for them TQt emulates the required
+ functionality. For example, the Oracle and ODBC drivers have
+ proper prepared query support, and TQt makes use of it; but for
+ databases that don't have this support, TQt implements the feature
+ itself, e.g. by replacing placeholders with actual values when a
+ query is executed. The exception is positional binding using named
+ placeholders, which requires that the database supports prepared
+ queries.
+
+ Oracle databases identify placeholders by using a colon-name
+ syntax, e.g \c{:name}. ODBC simply uses \c ? characters. TQt
+ supports both syntaxes (although you can't mix them in the same
+ query).
+
+ Below we present the same example using each of the four different
+ binding approaches.
+
+ <b>Named binding using named placeholders</b>
+ \code
+ TQSqlQuery query;
+ query.prepare( "INSERT INTO atable (id, forename, surname) "
+ "VALUES (:id, :forename, :surname)" );
+ query.bindValue( ":id", 1001 );
+ query.bindValue( ":forename", "Bart" );
+ query.bindValue( ":surname", "Simpson" );
+ query.exec();
+ \endcode
+
+ <b>Positional binding using named placeholders</b>
+ \code
+ TQSqlQuery query;
+ query.prepare( "INSERT INTO atable (id, forename, surname) "
+ "VALUES (:id, :forename, :surname)" );
+ query.bindValue( 0, 1001 );
+ query.bindValue( 1, "Bart" );
+ query.bindValue( 2, "Simpson" );
+ query.exec();
+ \endcode
+ <b>Note:</b> Using positional binding with named placeholders will
+ only work if the database supports prepared queries. This can be
+ checked with TQSqlDriver::hasFeature() using TQSqlDriver::PreparedQueries
+ as argument for driver feature.
+
+ <b>Binding values using positional placeholders #1</b>
+ \code
+ TQSqlQuery query;
+ query.prepare( "INSERT INTO atable (id, forename, surname) "
+ "VALUES (?, ?, ?)" );
+ query.bindValue( 0, 1001 );
+ query.bindValue( 1, "Bart" );
+ query.bindValue( 2, "Simpson" );
+ query.exec();
+ \endcode
+
+ <b>Binding values using positional placeholders #2</b>
+ \code
+ query.prepare( "INSERT INTO atable (id, forename, surname) "
+ "VALUES (?, ?, ?)" );
+ query.addBindValue( 1001 );
+ query.addBindValue( "Bart" );
+ query.addBindValue( "Simpson" );
+ query.exec();
+ \endcode
+
+ <b>Binding values to a stored procedure</b>
+ This code calls a stored procedure called \c AsciiToInt(), passing
+ it a character through its in parameter, and taking its result in
+ the out parameter.
+ \code
+ TQSqlQuery query;
+ query.prepare( "call AsciiToInt(?, ?)" );
+ query.bindValue( 0, "A" );
+ query.bindValue( 1, 0, TQSql::Out );
+ query.exec();
+ int i = query.boundValue( 1 ).toInt(); // i is 65.
+ \endcode

+ \brief The TQSqlRecord class encapsulates a database record, i.e. a
+ set of database fields.
+
+ \ingroup database
+ \module sql
+
+ The TQSqlRecord class encapsulates the functionality and
+ characteristics of a database record (usually a table or view within
+ the database). TQSqlRecords support adding and removing fields as
+ well as setting and retrieving field values.
+
+ TQSqlRecord is implicitly shared. This means you can make copies of
+ the record in time O(1). If multiple TQSqlRecord instances share
+ the same data and one is modifying the record's data then this
+ modifying instance makes a copy and modifies its private copy -

+ \code
+ ...
+ TQSqlSelectCursor* cur = new TQSqlSelectCursor( "SELECT id, firstname, lastname FROM author" );
+ TQDataTable* table = new TQDataTable( this );
+ table->setSqlCursor( cur, TRUE, TRUE );
