You can create an error logging table that you associate with a permanent base table when you want Vantage to log information about the following:
- Insert errors that occur during an SQL INSERT ... SELECT operation on the permanent base table
- Update and insert errors that occur during an SQL MERGE operation on the permanent base table
To enable error logging for an INSERT ... SELECT or MERGE statement, specify the LOGGING ERRORS option.
| IF a MERGE operation or INSERT … SELECT operation generates errors that … | AND the request … | THEN the error logging table contains … |
|---|---|---|
| the error logging facilities can handle | completes |
The presence of the marker row means the request completed successfully. |
| aborts and rolls back when referential integrity (RI) or unique secondary index (USI) violations are detected during index maintenance |
The absence of a marker row in the error logging table means the request was aborted. |
|
| reach the error limit specified by the LOGGING ERRORS option | aborts and rolls back | an error row for each error that the operation generated, including the error that caused the error limit to be reached. |
| the error logging facilities cannot handle | aborts and rolls back | an error row for each error that the operation generated until the error that the error logging facilities could not handle. |
You can use the information in the error logging table to determine how to recover from the errors, such as which data rows to delete or correct and whether to rerun the request.
