slow why?

Answer Posted / chockalingam

There might be several reasons for the dealy

1) Network might be slower today compared to yesterday
2) Data might have increased substantially
3) Concorrent users might be running the query at the same
time
4) There might be lock established on the table from
another resource
5) temp memory might be less today. May be Server space
related issue.
