Question

    DECLARE @TestVal int SET @TestVal = 5  SELECT     CASE         WHEN @TestVal <=3 THEN 'Top 3'         ELSE 'Other'     END 

I saw this sample code online but I couldn’t find an example where there was no expression and it had more than one WHEN, so I am wondering if this type of thing is OK:

    DECLARE @TestVal int SET @TestVal = 5  SELECT     CASE         WHEN @TestVal <=3 THEN 'Top 3'                 WHEN (select ...) = 1 THEN 'Other Value'                 WHEN (select ...) = 2 THEN 'Other Value 2'         ELSE 'Other'     END 

Or do I need to say CASE WHEN for each line?

Answer 1

Case takes the following form

CASE WHEN Condition THEN Result      WHEN Condition2 THEN Result2 ELSE Default END 

Edit

This assumes your using Microsoft SQL Server other DBMS might be different
