\brief The QSqlError class provides SQL database error information.

\ingroup database

|
|
|
|
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.
