Question

I have the following @temp table :

------------------------------------
|Condition_ID   Operator   Order    |
|     1            ==        1      |
|     2            <>        3      |
|     3            ==        2      |
------------------------------------

I want to implement a SELECT CASE that will output a certain message depending on the Operator

However this throws me an Incorrect syntax near the keyword 'PRINT'. error.

SELECT CASE
    WHEN Operator LIKE '=='
        THEN PRINT 'EQUALS'
    WHEN Operator LIKE '<>'
        THEN PRINT 'NOT EQUALS'
END AS Operator
FROM @temp

What am I doing wrong?

Answer 1

You just need to remove the PRINT

SELECT CASE
    WHEN Operator LIKE '=='
        THEN 'EQUALS'
    WHEN Operator LIKE '<>'
        THEN 'NOT EQUALS'
END AS Operator
FROM @temp

You can’t use a PRINT inside a SELECT, and you don’t need to – the SELECT will retrieve the appropriate value for you.
