DESCRIPTION

The QSqlError class provides SQL database error information.

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.

See also Database Classes.

Member Type Documentation

QSqlError::Type

This enum type describes the type of SQL error that occurred.

QSqlError::None - no error occurred

QSqlError::Connection - connection error

QSqlError::Statement - SQL statement syntax error

QSqlError::Transaction - transaction failed error

QSqlError::Unknown - unknown error

MEMBER FUNCTION DOCUMENTATION

QSqlError::QSqlError ( const QString & driverText = QString::null, const QString & databaseText = QString::null, int type = QSqlError::None, int number = -1 )

Constructs an error containing the driver error text driverText, the database-specific error text databaseText, the type type and the optional error number number.

QSqlError::QSqlError ( const QSqlError & other )

Creates a copy of other.

QSqlError::~QSqlError () [virtual]

Destroys the object and frees any allocated resources.

QString QSqlError::databaseText () const

Returns the text of the error as reported by the database. This may contain database-specific descriptions.

QString QSqlError::driverText () const

Returns the text of the error as reported by the driver. This may contain database-specific descriptions.

int QSqlError::number () const

Returns the database-specific error number, or -1 if it cannot be determined.

QSqlError & QSqlError::operator= ( const QSqlError & other )

Sets the error equal to other.

void QSqlError::setDatabaseText ( const QString & databaseText ) [virtual]

Sets the database error text to the value of databaseText.

void QSqlError::setDriverText ( const QString & driverText ) [virtual]

Sets the driver error text to the value of driverText.

void QSqlError::setNumber ( int number ) [virtual]

Sets the database-specific error number to number.

void QSqlError::setType ( int type ) [virtual]

Sets the error type to the value of type.

void QSqlError::showMessage ( const QString & msg = QString::null ) const

This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code.

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 msg parameter, which will be concatenated with the text() message.

See also text(), driverText(), and databaseText().

QString QSqlError::text () const

This is a convenience function that returns databaseText() and driverText() concatenated into a single string.

See also showMessage(), driverText(), and databaseText().

int QSqlError::type () const

Returns the error type, or -1 if the type cannot be determined.

See also QSqlError::Type.
