PsqlException Object
Show this topic in Library frames
The PsqlException object is created and thrown when the Pervasive.SQL server returns an error. Exceptions generated by the data provider itself are returned as standard run time exceptions.
The properties described in Table 4-15 apply to the last error generated, if multiple errors exist. The application should check the Count property of the PsqlErrorCollection returned in the Errors property of this object to determine whether multiple errors occurred. See PsqlErrorCollection Object for more information.
