使用ANYELEMENT和实体SQL的子查询

根据MicrosoftDocumentsforEntitySQL，为了返回标量子查询，我需要使用函数ANYELEMENT

但是，当我尝试将其作为返回值时：

System.Data.Query.ResultAssembly.BridgeDataRecord

我的问题是：

SELECT

ANYELEMENT(
SELECT SUM(CASE WHEN B.EXECUTION_STATUS_ID=2 THEN 1 ELSE 0 END)
    FROM SpiraTestEntities.R_TestCases AS B
    WHERE TruncateTime(B.EXECUTION_DATE) <= DateExecuted) AS PASSED,

DateExecuted


FROM SpiraTestEntities.R_TestCases as A

where A.PROJECT_ID = ${ProjectId}

AND A.IS_DELETED = false

AND A.EXECUTION_DATE IS NOT NULL

GROUP BY 

TruncateTime(A.EXECUTION_DATE) as DateExecuted

但我明白了：

PASSED                                                      DateExecuted
------                                                      ------------
System.Data.Query.ResultAssembly.BridgeDataRecord            2014-06-05
System.Data.Query.ResultAssembly.BridgeDataRecord            2014-06-06
System.Data.Query.ResultAssembly.BridgeDataRecord            2014-06-09

有什么想法吗

在选择后添加值：

PASSED                                                      DateExecuted
------                                                      ------------
System.Data.Query.ResultAssembly.BridgeDataRecord            2014-06-05
System.Data.Query.ResultAssembly.BridgeDataRecord            2014-06-06
System.Data.Query.ResultAssembly.BridgeDataRecord            2014-06-09
