Index created from index &1 for table &2 |
Cause Text: |
A temporary index was created using the specified index to access rows
from the queried table for one of the following reasons: - Perform specified ordering/grouping criteria.
- Perform specified join criteria.
The table number refers to the relative position of this table in the
query. |
Recovery Text: |
Creating an index from an index is generally a good performing option.
Consider creating a permanent index for frequently run queries. The query
can be run in debug mode (STRDBG) to determine
the key columns used when creating the index. NOTE: If a permanent index is
created, it is possible the query optimizer may still choose to create a temporary
index to access the rows from the table. |
