<hr><a name="details"></a><h2>Detailed Description</h2>




<p> The QSqlDatabase class is used to create SQL database
connections and provide transaction handling.
<p> 
<p> This class is used to create connections to SQL databases. It also
provides transaction handling functions for those database drivers
that support transactions.
<p> The QSqlDatabase class itself provides an abstract interface for
accessing many types of database backend. Database-specific drivers
are used internally to actually access and manipulate data, (see
<a href="qsqldriver.html">QSqlDriver</a>). Result set objects provide the interface for executing
and manipulating SQL queries (see <a href="qsqlquery.html">QSqlQuery</a>).
<p> <p>See also <a href="database.html">Database Classes</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QSqlDatabase"></a>QSqlDatabase::QSqlDatabase ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;driver, const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;name, <a href="qobject.html">QObject</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;objname = 0 )<tt> [protected]</tt>
</h3>  Creates a QSqlDatabase connection named <em>name</em> that uses the
driver referred to by <em>driver</em>, with the parent <em>parent</em> and
the object name <em>objname</em>.  If the <em>driver</em> is not recognized,
the database connection will have no functionality.
<p> The currently available drivers are:
<p> <ul>
<li> <a href="sql-driver.html#QODBC3">QODBC3</a> - ODBC (Open Database Connectivity) Driver
<li> <a href="sql-driver.html#QOCI8">QOCI8</a> - Oracle Call Interface Driver
<li> <a href="sql-driver.html#QPSQL7">QPSQL7</a> - PostgreSQL v6.x and v7.x Driver
<li> <a href="sql-driver.html#QTDS7">QTDS7</a> - Sybase Adaptive Server and Microsoft SQL Server Driver
<li> <a href="sql-driver.html#QMYSQL3">QMYSQL3</a> - MySQL Driver
</ul>
<p> Note that additional 3<sup>rd</sup> party drivers can be loaded
dynamically.
<p> 
<h3 class=fn><a name="~QSqlDatabase"></a>QSqlDatabase::~QSqlDatabase ()
</h3> Destroys the object and frees any allocated resources.
<p> 
<h3 class=fn><a href="qsqldatabase.html">QSqlDatabase</a>&nbsp;* <a name="addDatabase"></a>QSqlDatabase::addDatabase ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;type, const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;connectionName = defaultConnection )<tt> [static]</tt>
</h3>  Adds a database to the list of database connections using the
driver <em>type</em> and the connection name <em>connectionName</em>.
<p> The database connection is referred to by <em>connectionName</em>.  A
pointer to the newly added database connection is returned.  This
pointer is owned by QSqlDatabase and will be deleted on program exit
or when <a href="#removeDatabase">removeDatabase</a>() is called.  If <em>connectionName</em> is not
specified, the newly added database connection becomes the default
database connection for the application, and subsequent calls to
<a href="#database">database</a>() (without a database name parameter) will return a pointer
to it.
<p> <p>See also <a href="#database">database</a>() and <a href="#removeDatabase">removeDatabase</a>().

<p> 
<p>Examples: <a href="sql.html#x2256">sql/overview/connect1/main.cpp</a>, <a href="sql.html#x2262">sql/overview/create_connections/main.cpp</a> and <a href="sqltable-example.html#x2637">sql/sqltable/main.cpp</a>.
<h3 class=fn>void <a name="close"></a>QSqlDatabase::close ()
</h3> Closes the database connection, freeing any resources acquired.
<p> 
<h3 class=fn>bool <a name="commit"></a>QSqlDatabase::commit ()
</h3> Commits a transaction to the database if the driver supports transactions.
Returns TRUE if the operation succeeded, FALSE otherwise.
<p> <p>See also <a href="qsqldriver.html#hasFeature">QSqlDriver::hasFeature</a>() and <a href="#rollback">rollback</a>().

<h3 class=fn>bool <a name="contains"></a>QSqlDatabase::contains ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;connectionName = defaultConnection )<tt> [static]</tt>
</h3> Returns TRUE if the list of database connections contains <em>connectionName</em>, otherwise returns FALSE.
<p> 
<h3 class=fn><a href="qsqldatabase.html">QSqlDatabase</a>&nbsp;* <a name="database"></a>QSqlDatabase::database ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;connectionName = defaultConnection, bool&nbsp;open = TRUE )<tt> [static]</tt>
</h3> Returns a pointer to the database connection named <em>connectionName</em>.  The database connection must have been previously
added with <a href="#database">database</a>().  If <em>open</em> is TRUE (the default) and the
database connection is not already open it is opened now.  If no <em>connectionName</em> is specified the default connection is used. If <em>connectionName</em> does not exist in the list of databases, 0 is
returned.  The pointer returned is owned by QSqlDatabase and should
<em>not</em> be deleted.
<p> 
<p>Examples: <a href="sql.html#x2270">sql/overview/basicbrowsing/main.cpp</a> and <a href="sql.html#x2263">sql/overview/create_connections/main.cpp</a>.

<h3 class=fn><a href="qstring.html">QString</a> <a name="driverName"></a>QSqlDatabase::driverName () const
</h3> Returns the name of the driver used by the database connection.

</h3> Executes an SQL statement (e.g. an INSERT, UPDATE or DELETE statement)
on the database, and returns a <a href="qsqlquery.html">QSqlQuery</a> object.  Use <a href="#lastError">lastError</a>()

</h3> This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
