Question

我有这个存储过程：

CREATE PROCEDURE [dbo].[getCorrespondingRespcode]
@rc char(3)
AS
BEGIN
    SET NOCOUNT ON;

    DECLARE @webRcCount int

    SELECT webRc, COUNT(*) as webRcCount  
    FROM payterm.response_codes_mapping  
    WHERE rc = @rc GROUP BY webRc
END

如何使用@webRcCount的值设置webRcCount？我需要做if @webRcCount = 1 print'ok'

Answer 1

SELECT @webRcCount = COUNT(*) 
FROM payterm.response_codes_mapping 
WHERE rc = @rc

SELECT @webRcCount AS [WebRCCount]

应该这样做......

Answer 2

您是否要在表格中计算不同的 webRc值？如果是这样，请改用：

SELECT @webRcCount = COUNT(DISTINCT webRC) 
FROM payterm.response_codes_mapping 
WHERE rc = @rc;

存储过程计数（*）
