尝试在mysql的情况下包含“或”-错误代码：1241。操作数应包含1列

Question

I'm trying to include an "OR" clause in a CASE but I keep getting

"Error Code: 1241. Operand should contain 1 column(s)

Here's a sample of the query.

       select [...],
            CASE  
                when category1.Category1Name in (...) or category1.Category1Name like (...) then 'L-ACCESSORIES'
                when[...]
            end as 'Style'
       from [...]

If someone could shed some like on this it'd be much appreciated.

Answer 1

this syntax completely worked on mysql

SELECT OrderID, Quantity,
CASE
    WHEN Quantity like 3 or quantity like 100 THEN "The quantity is either 3 or 100"

    ELSE "The quantity is something else"
END
FROM OrderDetails;

but when i used in instead of like it didn't work so the issue is not with or it's with ==> in . each case must be closed as well

Answer 2

The issue is most likely coming from your like statement. It can only contain 1 value. If you write

like(1,2) 

you will get this error.

All other operations should work in mysql .
