Re: slow cursor

This is one thing that I always try to avoid, a single INSERT INTO...SELECT ...FROM or single UPDATE is always faster compared to looping the same within a cursor, unless its inevitable.

Hi

 

I have a cursor that fetches 150K rows and updates or inserts a table with 150K rows.

 

It takes several minutes for the process to complete (about 15 minutes). The select by itself (without cursor) gets all rows in 15 seconds.

 

Is there a way to optimize the cursor to fetch all records and speed up the process. I still need to do the record by record processing
