[TRAFODION-2331] UPD STATS sometimes fails silently after some other â¦
â¦failure
There are three changes in this check-in:
1. UPDATE STATISTICS does a ROLLBACK after detecting a SQL error. Sometimes
the ROLLBACK fails, because the Executor has already rolled back the
transaction. This caused UPDATE STATISTICS to get confused about transaction
state. This has been fixed; now after an error on ROLLBACK, UPDATE STATISTICS
simply checks to see if a transaction is still active, and if not, just ignores
the error.
2. When executing DDL statements, UPDATE STATISTICS tries to start a
transaction. If it is confused about transaction state (as in item 1 above), it
thinks this attempt to start a transaction has failed. In that particular case,
no error was being reported. This has been fixed.
3. Some obsolete code that used static SQL for BEGIN WORK, COMMIT and
ROLLBACK has been removed.
