\inmodule QtSql
A QSqlError object can provide database-specific error data,
including the driverText() and databaseText() messages (or both
concatenated together as text()), and the error number() and
type(). The functions all have setters so that you can create and
return QSqlError objects from your own classes, for example from
your own SQL drivers.
