BUG #: 363745 (SHILOH_BUGS)

SYMPTOMS

If you run an UPDATE statement on the partitioning column of a partitioned view and the UPDATE statement includes an inner join to another table, a scan of each partition table may be performed. This problem occurs although a useful index exists on each table. Depending on the size of each partition table, this can have a negative, and sometimes severe, effect on performance.

This problem only occurs when all the following conditions are true:

You are updating a partitioned view.
The partitioning column is included in the list of column names that are to be updated.
The UPDATE statement includes an inner join to another table.
