I've stuck in an MS SQL SERVER 2012 Query. What i want, is to write multiple values in "CASE" operator in "IN" statement of WHERE clause, see the following:
WHERE [CLIENT] IN (CASE WHEN T.[IS_PHYSICAL] THEN 2421, 2431 ELSE 2422, 2432 END)
The problem here is in 2421, 2431 - they cannot be separated with comma. is there any solution to write this in other way? thanks.

using the equality operator (=). If you want to use other comparison operators such as greater than (>), less than (<), etc., you use the searched CASE expression. The CASE statement returns the result_1, result_2, or result_3 if the expression matches the corresponding expression in the WHEN clause.
CASE can be used in any statement or clause that allows a valid expression. For example, you can use CASE in statements such as SELECT, UPDATE, DELETE and SET, and in clauses such as select_list, IN, WHERE, ORDER BY, and HAVING.
A quick review of CASE basics:You can make any conditional statement using any conditional operator (like WHERE ) between WHEN and THEN . This includes stringing together multiple conditional statements using AND and OR .
This is simpler if you don't use case in the where clause. Something like this:
where (T.[IS_PHYSICAL] = 1 and [client] in (2421, 2431)) or
(T.[IS_PHYSICAL] = 0 and [client] in (2422, 2432))
