"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

what is datatype of wcat

try

SELECT  wid, wcat FROM watches WHERE wcat <> 'o' AND wid = 70073

or

SELECT  wid, wcat FROM watches WHERE wcat not like  'o' AND wid = 70073

You should handle NULL properly, NULL is always a trouble maker;

Use the below sample, this should help you;

SELECT  wid, wcat FROM watches WHERE ISNULL(wcat,'') != 'o' AND wid = 70073

OR

SELECT  wid, wcat FROM watches WHERE ISNULL(wcat,'') <> 'o' AND wid = 70073
