Dropping indexes and updating ddfs PSQL v10.10

Dropping indexes and updating ddfs PSQL v10.10

Dropping indexes and updating ddfs PSQL v10.10

(OP)
I needed to drop some indexes from two tables to accomodate MS Access' index restrictions.  I did this via the PSQL - Utilities - Maintenance (aka Btrieve Maintenance Utility). Now I'd like to save these changes to the ddfs.  A few years ago when I did this in v8 or 9, it was a simple save and update or recreate.  From the BMU or the PCC, I can't see where to do this in v10.10. I'd appreciate your guidance in this matter.

Thank you!!

RE: Dropping indexes and updating ddfs PSQL v10.10

The best suggestion would be to use DROP INDEX IN DICTIONARY statements.  For example:
DROP INDEX <index name> IN DICTIONARY

This will remove the indexes from the DDFs but not the data files (since there aren't any on the data files).

The DROP INDEX is a standard SQL statement so you'd connect through PCC and open a new SQL document (like you were going to SELECT data and just run the DROP INDEX instead).
