Question

SELECT _cotM.Customer_ID, _cotM.Material_ID
FROM dbo.COT_Monthly AS cot 
INNER JOIN
dbo.vw_Dim_Material AS matr ON cot.Material_ID = matr.Material_ID  
GROUP BY _cotM.Customer_ID, _cotM.Material_ID

I have sql code and have result 25855 rows

but when i add where matr.Brand <> '%VIT%' upper group by the result still 25855 rows.

but when i delete wildcard where matr.Brand <> 'VIT' the result became 25089.

i wandering why the result like this ?

is i am wrong using wildcard or else?

Thanks for answering.

Answer 1

Wildcards only work with LIKE clauses, so change the condition:

WHERE matr.Brand NOT LIKE '%VIT%'
