hello

how can i work with parameters, working with case, sum etc... instructions?
For example i have these lines that select some values, these values i want to store in a parameter because i want to SUM those fields after.... how is the better way to do this?


      CASE WHEN SUM(CASE WHEN A.TYPE_MOV = 1 THEN A.VALUE_MOV * -1 ELSE A.VALUE_MOV END) > 0 THEN SUM(CASE WHEN A.TYPE_MOV = 1 THEN A.VALOR_MOV * -1 ELSE A.VALUE_MOV END) ELSE 0 END AS VALUE_RECEIVE,
CASE WHEN SUM(CASE WHEN A.TYPE_MOV = 1 THEN A.VALUE_MOV * -1 ELSE A.VALUE_MOV END) < 0 THEN SUM(CASE WHEN A.TYPE_MOV = 1 THEN A.VALUE_MOV * -1 ELSE A.VALUE_MOV END) ELSE 0 END AS VALOR_PAY,

--Try like this...

SELECT CASE WHEN VALOR_PAY1 WHEN >0 THEN VALUE_MOV1 ELSE 0 END VALUE_RECEIVE
	,CASE WHEN VALOR_PAY1 <0 THEN VALOR_PAY1 ELSE 0 END VALOR_PAY
FROM  (SELECT SUM(CASE WHEN A.TYPE_MOV = 1 THEN A.VALUE_MOV * -1 ELSE A.VALUE_MOV END) VALOR_PAY1
			,SUM(CASE WHEN A.TYPE_MOV = 1 THEN A.VALOR_MOV * -1 ELSE A.VALUE_MOV END) VALUE_MOV1
