Hello,
I am using SQL Loader thru DataStage.
I have to load a partitioned table with partitioned index on countries. Let's say I want to load 2 countries.
What I'd like to do is to set the 2 partition of my index to unusable, then load using SQL Loader direct mode then rebuild only my two partitions of the index.
But SQL Loader set all index partitions to unusable, thus I have to rebuild all the partitions which is a drawback for performance.
Is there a way to load without setting to unusable the partitions I'm not loading into ?
I did several tests using SKIP_UNUSABLE_INDEXES and SKIP_INDEX_MAINTENANCE but wasn't able to achieve this...
Any idea ??
Thanks and Regards,
Ben

I don't know what "DataStage" is & I am too lazy to try to look it up.

One possible way would be to "declare" the data file to be an external table & the use SQL or PL/SQL to move the data from the file into the target table.
