在强类型数据集中子查询的计算

Question

以下背景：我有一个Table-valued Function，它返回一个Table，它是一个大型表上的过滤视图（视图不能被参数化）。现在我需要不同条件下的很多行计数值。是否可以在一个查询中获取所有计数值，而无需为每个条件查询此函数？

为了完整起见（它并不真正的问题，你可以阅读过它），这是功能：

CREATE FUNCTION [dbo].[getRuleConfigBySetSlsRules] (
@fiRuleSet AS TinyInt, 
@fiServiceLocations AS NVARCHAR(4000), 
@fiRules AS NVARCHAR(400) 
) 

RETURNS TABLE AS RETURN (
SELECT  ruleChangeTo.fiSet, ruleChangeTo.fiClaimStatus, ruleChangeTo.fiRule, ruleChangeTo.fiSL, ruleChangeTo.fiResult, 
         dimClaimStatus.ClaimStatusName AS OldStatus, dimClaimStatus_1.ClaimStatusName AS NewStatus, locSL.SLName, ruleSet.SetName, 
         ruleResult.ResultName, locMarketUnit.MarketUnitName, locCountry.CountryName, ruleRule.RuleKey, ruleRule.RuleName, ruleRule.RuleDescription, 
         locGSP.WCMSName AS GSP_WCMSName, locGSP.Active AS GSP_Active, locGSP.WCMSKeyNumber AS GSP_WCMSKeyNumber, 
         locSL.Active AS SL_Active, locSL.WCMSName AS SL_WCMSName, locSL.WCMSKeyNumber AS SL_WCMSKeyNumber, locSL.fiSLType, 
         locSLType.SLTypeName, ruleChangeTo.fiClaimStatus_ChangeTo 
FROM   locGSP INNER JOIN 
         locCountry ON locGSP.fiCountry = locCountry.idCountry INNER JOIN 
         locMarketUnit ON locCountry.fiMarketUnit = locMarketUnit.idMarketUnit INNER JOIN 
         locSL ON locGSP.idGSP = locSL.fiGSP INNER JOIN 
         ruleChangeTo ON locSL.idSL = ruleChangeTo.fiSL INNER JOIN 
         dimClaimStatus ON ruleChangeTo.fiClaimStatus = dimClaimStatus.idClaimStatus INNER JOIN 
         ruleResult ON ruleChangeTo.fiResult = ruleResult.idResult INNER JOIN 
         ruleRule ON ruleChangeTo.fiRule = ruleRule.idRule INNER JOIN 
         ruleSet ON ruleChangeTo.fiSet = ruleSet.idSet INNER JOIN 
         locSLType ON locSL.fiSLType = locSLType.idSLType INNER JOIN 
         dimClaimStatus AS dimClaimStatus_1 ON ruleChangeTo.fiClaimStatus_ChangeTo = dimClaimStatus_1.idClaimStatus INNER JOIN 
         dbo.Split(@fiServiceLocations, ',') AS ServiceLocations ON ServiceLocations.Item = ruleChangeTo.fiSL INNER JOIN 
         dbo.Split(@fiRules, ',') AS Rules ON ruleChangeTo.fiRule = Rules.Item 
WHERE (ruleChangeTo.fiSet = @fiRuleSet) 
) 

而在下面的方法可以让我得到一个计数值，但实际上我需要30个条件在同一个查询（WHERE子句）。

什么是一个强类型数据集来做到这一点，而不为每一个值查询的最佳方式？我不知道。 这是一个必须与各种状态条件和它们的计数值被扩展（超出上述图像的）查询：

SELECT  COUNT(*) AS CountValidReject 
FROM   dbo.getRuleConfigBySetSlsRules(@fiSet, @ServiceLocations, @Rules) AS RuleConfigFilter 
WHERE  (fiClaimStatus = 1) AND (fiClaimStatus_ChangeTo = 8) 

前来点：我需要与TEMP-一个存储过程表或类似的东西，或者我可以在数据集中的这个SQL中创建和查询临时表？我不想为每个值调用getRuleConfigBySetSlsRules。

感谢

编辑： 这是返回1行与许多计数值列最终的查询。感谢Steve再次提供CASE WHEN提示。它非常有效。

Answer 1

如果你更具体并给出了一个例子，这将有很大的帮助。我不确定同一个查询（WHERE子句）中的“30个条件”是什么意思，或者“强类型化”与什么有关。你能给出你想要的30件事的两个或三个例子吗？

猜测你想要的东西是这样的：

SELECT 
    COUNT(CASE WHEN (fiClaimStatus = 1) AND (fiClaimStatus_ChangeTo = 8) 
     THEN 1 ELSE NULL END) AS myCount1, 
    COUNT(CASE WHEN (fiClaimStatus = 2) AND (fiClaimStatus_ChangeTo = 8) 
     THEN 1 ELSE NULL END) AS myCount2, 
    COUNT(CASE WHEN (fiClaimStatus = 2) AND (fiClaimStatus_ChangeTo = 6) 
     THEN 1 ELSE NULL END) AS myCount1, 
    ... 
FROM dbo.getRuleConfigBySetSlsRules(@fiSet, @ServiceLocations, @Rules) AS T 

如果不靠近你所需要的，请提供更多信息。

我没有看到任何解决方法。将表值函数的结果放入临时表中，然后运行聚合查询。
