    \class QSqlError

    \brief The QSqlError class provides SQL database error information.

    \ingroup database

    \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.

    \value StatementError  SQL statement syntax error.
