Summary0003833: Improve performance and accuracy of DDL retrieval of Oracle Indexes (3.10)
DescriptionThe "readIndecies" phase of loading a table on Oracle was found to take 1-2 seconds at times during Oracle testing. The slowness appears to be related to a NOT IN/subselect clause in the SQL reading the indexes.

The change here is to issue 2 separate queries to filter out the PK indexes from the list. This seems to show significant performance improvement (now readIndecies is taking 1-10 milliseconds instead of over 1 second).

Also changed this code to use ALL_INDEXES instead of USER_INDEXES so there is better chance for visibility on Indexes that aren't owned by the current user.
TagsNo tags attached.
