强类型数据集中子查询的计算

strongly-typed-dataset subquery sql-server sql .net

为了完整性(这并不重要,你可以仔细阅读),函数如下:

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)
)

通过下面的方法,我可以得到一个计数值,但事实上,在同一个查询(WHERE子句)上我需要30个条件。

alt text

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

关键是:我是否需要一个带有临时表之类的存储过程,或者我是否可以在数据集中的这个sql中创建和查询临时表?我不想打电话 GetRuleConfigBySetsRules设置规则 每一个价值观。

谢谢

如果你更具体一点,举个例子,会有很大帮助。我不确定“同一查询上的30个条件(WHERE子句)”是什么意思,也不确定“强类型”与什么有什么关系。你能举两三个你想要的30件事的例子吗?

猜猜你想要什么是这样的:

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

如果这与您的需求不符,请提供更多信息。

我看不出有什么办法。将表值函数的结果放入临时表中,然后运行聚合查询。
