Hi everyone,
Thank you for your help. But my query is not always slow. It works fast
under normal conditions, but in a way that I don't understand it works very
slow at some times.
I think there may be a different reason why a query that takes 800ms, in
general, takes 18 minutes at a time.
Thanks a lot
Liam
