Re: Need to capture information when something is NOT there

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?
