63 | A QSqlError object can provide database-specific error data,

64 | including the driverText() and databaseText() messages (or both
|
---|
65 | concatenated together as text()), and the error number() and
|
---|
66 | type(). The functions all have setters so that you can create and
|
---|
67 | return QSqlError objects from your own classes, for example from
|
---|
68 | your own SQL drivers.
