Description

ErrorUI provides the Error UIwindow, which contains information about an SQL error resulting from an invalid SQL statement:

an error-location string that consists of the invalid SQL statement with the following inserted as a marker at the point of error: ----->>

The database-specific error message associated with the particular SQL error

The SQL error code associated with the error

The Statement and Process_error input values are available from the relevant module in the application; for example, DBquery. The remaining values are available from the database-independent layer via the main communication area descriptor for the current SQL operation. The Statement, Error_offset, and Process_error values are passed to DBerrorString for processing into the error-location message; it and the SQL error message and code are provided to users in the Error window.
