Can you post your trigger so we can see what else is happening? I do not
see where having the SELECT as you have posted to be of any use
in a trigger. I think in order to get a NO DATA FOUND error in a trigger
from SELECT COUNT(*)... would be if it was a cursor.

Hi,
Count(*) will never return NO_DATA_FOUND..so NULL value being compared is
out of question

Hi Rich,
I doubt any NULL value being checked in the WHERE CLAUSE...
as u will be knowing a NULL is not equal to another NULL.... in oracle !!
Just try applying NVL on such possible columns ....
Hope this may help u.
regards,
Arul.
