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.

< / 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 = "tqsqlerror.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 = "tqstring.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 = "tqstring.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 = "tqsqlerror.html" > TQSqlError< / a > & < a name = "operator-eq" > < / a > TQSqlError::operator= ( const < a href = "tqsqlerror.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 = "tqstring.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 = "tqstring.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 = "tqstring.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 = "tqstring.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.
