void QNullDriver::close | ( | void | ) | [inline, virtual] |
Derived classes must reimplement this abstract virtual function in order to close the database connection. Return TRUE on success, FALSE on failure.

QSqlQuery QNullDriver::createQuery | ( | ) | const [inline, virtual] |
Creates an empty SQL result on the database. Derived classes must reimplement this function and return a QSqlQuery object appropriate for their database to the caller.
Implementa QSqlDriver.
bool QNullDriver::hasFeature | ( | DriverFeature | f | ) | const [inline, virtual] |
Returns TRUE if the driver supports feature f; otherwise returns FALSE.
Note that some databases need to be open() before this can be determined.

bool QNullDriver::open | ( | const QString & | db, |
const QString & | user, | ||
const QString & | password, | ||
const QString & | host, | ||
int | port | ||
) | [inline, virtual] |
Derived classes must reimplement this abstract virtual function in order to open a database connection on database db, using user name user, password password, host host and port port.
The function must return TRUE on success and FALSE on failure.
