我可以在sql Server 2005的HAVING子句中使用case语句吗？
以下是我的HAVING声明.它给了我一个语法错误.
@CLIENTPK_NEW IS NULL OR
(
CLIENT.OH_PK = @CLIENTPK_NEW and
CASE WHEN @RelatedOrgs <> '11' then CLIENT.OH_PK= @CLIENTPK_NEW
ELSE CLIENT.OH_PK in (
SELECT dbo.OrgHeader.OH_PK FROM dbo.OrgHeader WITH (NOLOCK) INNER JOIN
dbo.OrgRelatedParty WITH (NOLOCK) ON dbo.OrgHeader.OH_PK = dbo.OrgRelatedParty.PR_OH_Parent INNER JOIN
dbo.OrgHeader AS OrgHeader_1 WITH (NOLOCK) ON dbo.OrgRelatedParty.PR_OH_RelatedParty = OrgHeader_1.OH_PK
where OrgHeader_1.OH_PK = @CLIENTPK_NEW
)
END
)
}
AND (@CGNEEPK IS NULL OR CGNEE.OH_PK = @CGNEEPK) AND
part.OP_RH_NKCommodityCode = @type@H_403_5@
谢谢,

解决方法
示例(从
here开始)：
USE AdventureWorks2008R2;
GO
SELECT JobTitle,MAX(ph1.Rate)AS MaximumRate
FROM HumanResources.Employee AS e
JOIN HumanResources.EmployeePayHistory AS ph1
ON e.BusinessEntityID = ph1.BusinessEntityID
GROUP BY JobTitle
HAVING (MAX(CASE WHEN Gender = 'M'
THEN ph1.Rate
ELSE NULL END) > 40.00
OR MAX(CASE WHEN Gender = 'F'
THEN ph1.Rate
ELSE NULL END) > 42.00)
ORDER BY MaximumRate DESC;@H_403_5@
