Re: SQL question

[Charles Wilt <charles.wilt@xxxxxxxxx>]

Your error is because you have a calculated column with no name...

But your SQL won't give you want you want anyway...this one will

Note I'm using the AS to assign a name

select
   CHAR_LENGTH(STRIP(CAT#)) as Len
   , count(*) as cnt
from file
where cat# <> ' '

Charles
group by CHAR_LENGTH(STRIP(CAT#))
