I am writing a purge program. I need to check if the item number exists in 12 different files. I was going to use count to see if the
item number is in each file, but was wondering if 'Select 1' and
check for an error would be a better approach. I thought I saw
something like this awhile ago, but cannot find it in the archives.


Probably a[n example of] WHERE EXISTS subquery is of interest. FWiW, an SQL question by itself, is not an RPG topic.
