I have a table with a column that contains fail codes. These codes are 1-9.
I need to get a count of each of the codes. Right now I have separate
queries:
select count(*) from tablename
where failcode = '1';
If I use GROUP BY it obviously doesn't get the count for codes that don't
exist. I need to have 0 returned though so I have a listing of all 9 fail
codes and their total, even if it is zero. I tried UNION like this:
select count(*) from tablename
where failcode = '1';
UNION
select count(*) from tablename
where failcode = '2';
etc, but it too excludes the codes that have a count of zero. Right now I
have resorted to using 9 separate queries. Is there a way to do this with
one? Thank you!
