Question

I have a very large sql statement I have to make a modification to. In one of the tables there are four int columns and I have to exclude 2 sets. If I just want to exclude the values for one table it is pretty simple, use an except statement. I can do this:

select *
from Table Z
except(
select *
from Table Z
where (A= 2 and B= 10 and C= 3 and D= 90) 
or (A= 2 and B= 17 and C= 100 and D= 90))

However I can’t get it to work using a where statement. I only want those two sets of combinations excluded. In the real statement there is a join with six different tables and all kinds of case statements in the select.

I have tried a few things and nothing seems to work.

Any ideas would be greatly appreciated!

Thanks!

Answer 1

Why the complex EXCEPT? Doesn’t this work?:

SELECT  *
FROM Table Z
WHERE NOT (  ( A= 2 and B= 10 and C= 3 and D= 90) 
          OR ( A= 2 and B= 17 and C= 100 and D= 90)
          )
