Alan, here's a few sites that may help out a bit plus assist any of our MidRange users that contribute here. I refer to this material often. There's many more but this is a decent start.
http://www.tylogix.com/ - Select the SQL page on the left.

is NOT there
Thanks for your response Vernon
Ive been trying to get this final piece of the logic, with no success, for almost a week now Your suggestion of where (fld1, fld2) not in (select fld1, fld2 from 6th file) maybe what I need
Once I get a couple of minutes (lol) I will play with this

Hi Alan
If you add another EXCEPTION JOIN on those 2 columns, your list would be what you want - or you can do a NOT IN - where (fld1, fld2) not in (select fld1, fld2 from 6th file) - that's really the same as EXCEPTION JOIN, though.
Do you need that extra column? What would it contain? I'm guessing some constant label, such as "not in file 6" or 'X' - just add that as a constant to the "field" list.
So what am I missing??? :)

Hi everyone
We are at V7r3
I hope that what I am about to ask, makes sense
I have an SQL query using 5 files with joins, exception joins etc,
that extracts a number of columns I would like to add another column,
that would use data from two of these columns and look in a sixth file
and let me know if there are NO records in that sixth file with those
2 values I cannot use any data from this sixth file as I am looking to
see if a "no record" condition exists
Anyone any ideas as to how to achieve this?
