在強類型數據集中子查詢的計算

Question

以下背景：我有一個Table-valued Function，它返回一個Table，它是一個大型表上的過濾視圖（視圖不能被參數化）。現在我需要不同條件下的很多行計數值。是否可以在一個查詢中獲取所有計數值，而無需爲每個條件查詢此函數？

爲了完整起見（它並不真正的問題，你可以閱讀過它），這是功能：

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讓我得到一個計數值，但實際上我需要30個條件在同一個查詢（WHERE子句）。

什麼是一個強類型數據集來做到這一點，而不爲每一個值查詢的最佳方式？我不知道。 這是一個必須與各種狀態條件和它們的計數值被擴展（超出上述圖像的）查詢：

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

前來點：我需要與TEMP-一個存儲過程表或類似的東西，或者我可以在數據集中的這個SQL中創建和查詢臨時表？我不想爲每個值調用getRuleConfigBySetSlsRules。

感謝

編輯： 這是返回1行與許多計數值列最終的查詢。感謝Steve再次提供CASE WHEN提示。它非常有效。

Answer 1

如果你更具體並給出了一個例子，這將有很大的幫助。我不確定同一個查詢（WHERE子句）中的「30個條件」是什麼意思，或者「強類型化」與什麼有關。你能給出你想要的30件事的兩個或三個例子嗎？

猜測你想要的東西是這樣的：

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，請提供更多信息。

我沒有看到任何解決方法。將表值函數的結果放入臨時表中，然後運行聚合查詢。
