Sure!! Thanks for the response. Apologies for multiple questions. Faced this during high priority MSSQL to PostgreSQL migration. Did not see any equivalent of XML PATH which would give desired results. Finally was able to resolve the issue by rewriting the Proc using WITH and string_aggr in combination. However still facing performance issues in the same. Will investigate it.

You realize that there are a million answers to your questions online? Are you doing any google searches before bothering this list with basic questions? I personally never email this list until I’ve exhausted all searches and extensive trial and error, as do most practitioners. This list is incredibly patient and polite, and...there are limits. Please consider doing more research before asking a question. In your example below, you’re getting a basic subquery error – research how to fix that. Mike
