Any ideas to make this query
Hi,
I have a select like
SELECT (array[20]+array[21]+ ... +array[50]+array[51]) as total
FROM table
WHERE
(array[20]+array[21]+ ... +array[50]+array[51])5000
AND array[20]0
AND array[21]0
...
AND array[50]0
AND array[51])0
Any ideas to make this query faster?

but I can't recall where.
I ll check it out, seems to be very useful
Is faster
