<hr><a name="details"></a><h2>Detailed Description</h2>
The TQSqlError class provides SQL database error information.
<p>
<p> This class is used to report database-specific errors. An error
description and (if appropriate) a database-specific error number
can be obtained using this class.
<p>See also <a href="database.html">Database Classes</a>.
<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Type-enum"></a>TQSqlError::Type</h3>
<p> This enum type describes the type of SQL error that occurred.
<ul>
<li><tt>TQSqlError::None</tt> - no error occurred
<li><tt>TQSqlError::Connection</tt> - connection error
<li><tt>TQSqlError::Statement</tt> - SQL statement syntax error
<li><tt>TQSqlError::Transaction</tt> - transaction failed error
<li><tt>TQSqlError::Unknown</tt> - unknown error
</ul>
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQSqlError"></a>TQSqlError::TQSqlError ( const <a href="ntqstring.html">TQString</a> & driverText = TQString::null, const <a href="ntqstring.html">TQString</a> & databaseText = TQString::null, int type = TQSqlError::None, int number = -1 )
</h3>
Constructs an error containing the driver error text <em>driverText</em>, the database-specific error text <em>databaseText</em>, the
type <em>type</em> and the optional error number <em>number</em>.
<h3 class=fn><a name="TQSqlError-2"></a>TQSqlError::TQSqlError ( const <a href="ntqsqlerror.html">TQSqlError</a> & other )
</h3>
Creates a copy of <em>other</em>.
<h3 class=fn><a name="~TQSqlError"></a>TQSqlError::~TQSqlError ()<tt> [virtual]</tt>
</h3>
Destroys the object and frees any allocated resources.
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="databaseText"></a>TQSqlError::databaseText () const
</h3>
Returns the text of the error as reported by the database. This
may contain database-specific descriptions.
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="driverText"></a>TQSqlError::driverText () const
</h3>
Returns the text of the error as reported by the driver. This may
contain database-specific descriptions.
<h3 class=fn>int <a name="number"></a>TQSqlError::number () const
</h3>
Returns the database-specific error number, or -1 if it cannot be
determined.
<h3 class=fn><a href="ntqsqlerror.html">TQSqlError</a> & <a name="operator-eq"></a>TQSqlError::operator= ( const <a href="ntqsqlerror.html">TQSqlError</a> & other )
</h3>
Sets the error equal to <em>other</em>.
<h3 class=fn>void <a name="setDatabaseText"></a>TQSqlError::setDatabaseText ( const <a href="ntqstring.html">TQString</a> & databaseText )<tt> [virtual]</tt>
</h3>
Sets the database error text to the value of <em>databaseText</em>.
<h3 class=fn>void <a name="setDriverText"></a>TQSqlError::setDriverText ( const <a href="ntqstring.html">TQString</a> & driverText )<tt> [virtual]</tt>
</h3>
Sets the driver error text to the value of <em>driverText</em>.
<h3 class=fn>void <a name="setNumber"></a>TQSqlError::setNumber ( int number )<tt> [virtual]</tt>
</h3>
Sets the database-specific error number to <em>number</em>.
<h3 class=fn>void <a name="setType"></a>TQSqlError::setType ( int type )<tt> [virtual]</tt>
</h3>
Sets the error type to the value of <em>type</em>.
<h3 class=fn>void <a name="showMessage"></a>TQSqlError::showMessage ( const <a href="ntqstring.html">TQString</a> & msg = TQString::null ) const
</h3>
<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> This is a convenience function that pops up a <a href="ntqmessagebox.html">TQMessageBox</a>
containing the message returned by <a href="#text">text</a>(). An additional string
can be passed in via the <em>msg</em> parameter, which will be
concatenated with the text() message.
<p> <p>See also <a href="#text">text</a>(), <a href="#driverText">driverText</a>(), and <a href="#databaseText">databaseText</a>().
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="text"></a>TQSqlError::text () const
</h3>
This is a convenience function that returns <a href="#databaseText">databaseText</a>() and
<a href="#driverText">driverText</a>() concatenated into a single string.
<p> <p>See also <a href="#showMessage">showMessage</a>(), <a href="#driverText">driverText</a>(), and <a href="#databaseText">databaseText</a>().
<h3 class=fn>int <a name="type"></a>TQSqlError::type () const
</h3>
Returns the error type, or -1 if the type cannot be determined.
