.SH DESCRIPTION
|
|
The TQSqlError class provides SQL database error information.
|
|
.PP
|
|
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.
|
|
.PP
|
|

.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "TQSqlError::TQSqlError ( const TQString & driverText = TQString::null, const TQString & databaseText = TQString::null, int type = TQSqlError::None, int number = -1 )"
|
|
Constructs an error containing the driver error text \fIdriverText\fR, the database-specific error text \fIdatabaseText\fR, the type \fItype\fR and the optional error number \fInumber\fR.
|
|
.SH "TQSqlError::TQSqlError ( const TQSqlError & other )"
|
|
Creates a copy of \fIother\fR.
|
|
.SH "TQSqlError::~TQSqlError ()\fC [virtual]\fR"
|
|
Destroys the object and frees any allocated resources.
|
|
.SH "TQString TQSqlError::databaseText () const"
|
|
Returns the text of the error as reported by the database. This may contain database-specific descriptions.
|
|
.SH "TQString TQSqlError::driverText () const"
|
|
Returns the text of the error as reported by the driver. This may contain database-specific descriptions.
|
|
.SH "int TQSqlError::number () const"
|
|
Returns the database-specific error number, or -1 if it cannot be determined.
|
|
.SH "TQSqlError & TQSqlError::operator= ( const TQSqlError & other )"
|
|
Sets the error equal to \fIother\fR.
|
|
.SH "void TQSqlError::setDatabaseText ( const TQString & databaseText )\fC [virtual]\fR"
|
|
Sets the database error text to the value of \fIdatabaseText\fR.
|
|
.SH "void TQSqlError::setDriverText ( const TQString & driverText )\fC [virtual]\fR"
|
|
Sets the driver error text to the value of \fIdriverText\fR.
|
|
.SH "void TQSqlError::setNumber ( int number )\fC [virtual]\fR"
|
|
Sets the database-specific error number to \fInumber\fR.
|
|
.SH "void TQSqlError::setType ( int type )\fC [virtual]\fR"
|
|
Sets the error type to the value of \fItype\fR.
|
|
.SH "void TQSqlError::showMessage ( const TQString & msg = TQString::null ) const"
|

\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
|
|
.PP
|
|
This is a convenience function that pops up a QMessageBox containing the message returned by text(). An additional string can be passed in via the \fImsg\fR parameter, which will be concatenated with the text() message.

|
|
.SH "TQString TQSqlError::text () const"
|
|
This is a convenience function that returns databaseText() and driverText() concatenated into a single string.
|
|
.PP
|
|
See also showMessage(), driverText(), and databaseText().
|
|
.SH "int TQSqlError::type () const"
|
|
Returns the error type, or -1 if the type cannot be determined.
