我有下面的代码，需要基于参数的情况条件。这可以实现吗？如何使用这种类型的sql..我没有看到任何变体方法可以在没有大小写的情况下执行此操作
BEGIN
DECLARE @INPUT AS VARCHAR(256)
set @input = 'NASS'
SELECT
sum(TRY_PARSE(DV.[ERSDataValues_AttributeValue1] as decimal)) AS NEWVALUE
FROM [VegetablesCoSD-Full].[CoSD].[ERSDataValues] DV LEFT JOIN [CoSD]. [ERSTimeDimension_LU] TD
ON DV.ERSDataValues_ERSTimeDimension_ID = TD.ERSTimeDimension_ID
WHERE DV.ERSDataValues_ERSStatisticType_ID1 = 45 AND
DV.ERSDataValues_ERSCommodity_ID = 519 AND
DV.ERSDataValues_ERSGeography_ID = 3346 AND
DV.ERSDataValues_ERSUnit_ID1 = 89 AND
TD.ERSTimeDimension_TimeDimensionType_ID = 11 and
CASE
when @INPUT = 'NASS' THEN
TD.ERSTimeDimension_Month in
('1','2','3','4','5','6','7','8','9','10','11','12')
WHEN @INPUT = 'BLS' THEN
TD.ERSTimeDimension_Month IN('JAN','FEB')
END
最佳答案
您可以使用 OR 代替，如下所示:
AND
( (@INPUT = 'MASS' AND TD.ERSTimeDimension_Month in ('1','2','3','4','5','6','7','8','9','10','11','12'))
OR
(@INPUT = 'BLS' AND TD.ERSTimeDimension_Month IN('JAN','FEB')
)
关于sql - 在带有 IN 条件的 where 子句中使用 CASE，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34125160/
