SQL Server 2014-代码中的错误

我想创建一个报告，该报告给出了某个LabourID（L_ID）每月的事务总数。但我似乎无法得到我想要得到的东西。SQL Server 2014-代码中的错误

我的代码如下：

SET NOCOUNT ON 

Declare @S AS DateTime = ISNULL(@StartDate,DateAdd(d,-60,GETDATE())) 
IF OBJECT_ID('tempdb..#Count') IS NOT NULL DROP TABLE #Count; 

SELECT Year(TranxDate) AS YY 
     ,Month(TranxDate) AS MM 
     ,TT.L_ID 
     ,count(IR.T_TransactionId) TranxCount 

INTO #Count 

FROM  IR 
INNER JOIN TT ON IR.T_TransactionId = TT.T_TransactionId 

WHERE [TranxDate] >= @StartDate 
    AND [Some condition] 
    AND [Some condition] 
    AND [Some condition] 
    AND TT.L_ID IN ('502','701','18','22','702','503') 

GROUP BY Year(TranxDate), Month(TranxDate), TT.L_ID 


SELECT YY 
     ,MM 
     ,(SELECT TranxCount FROM #Count WHERE L_ID = '701')ID701 
     ,(SELECT TranxCount FROM #Count WHERE L_ID = '502')ID502 
     ,(SELECT TranxCount FROM #Count WHERE L_ID = '18')ID18 
     ,(SELECT TranxCount FROM #Count WHERE L_ID = '22')ID22 
     ,(SELECT TranxCount FROM #Count WHERE L_ID = '702')ID702 
     ,(SELECT TranxCount FROM #Count WHERE L_ID = '503')ID503 

FROM #Count 

GROUP BY YY, MM, L_ID 

ORDER BY YY, MM

我从这个代码得到一条错误消息：

子查询返回多个值。当子查询遵循=，！=，<，< =，>，> =或当子查询用作表达式时，这是不允许的。是

的不是Temptable #COUNT的结果如下：有

Year Month L_ID TranxCount 
2016 9  18  4141 
2016 9  22  637 
2016 9  502  7782 
2016 9  503  531 
2016 9  701  7529 
2016 9  702  1577 
2016 10  18  4611 
2016 10  22  1007 
2016 10  502  9763 
2016 10  503  507 
2016 10  701  10093 
2016 10  702  2176 
2016 11  18  5421 
2016 11  22  1471 
2016 11  502  11505 
2016 11  503  613 
2016 11  701  12530 
2016 11  702  2569

我想有结果如下：

YEAR Month ID701 ID502 ID18 ID22 ID702 ID503 
2016 9  7529 7782 4141 637  1577 531 
2016 10  10093 9763 4611 1007 2176 507 
2016 11  12530 11505 5421 1471 2569 613 
2016 12  ... 
2017 1 
... 
... 
.. 
.

我在做什么错在我的代码？

编辑：

按@Sean建议，我添加以下代码：

SELECT YY 
     ,MM 
     , MAX(Case when L_ID = '701' then TranxCount end) as ID701 
     , MAX(Case when L_ID = '502' then TranxCount end) as ID502 
     , MAX(Case when L_ID = '18' then TranxCount end) as ID18 
     , MAX(Case when L_ID = '22' then TranxCount end) as ID22 
     , MAX(Case when L_ID = '702' then TranxCount end) as ID702 
     , MAX(Case when L_ID = '503' then TranxCount end) as ID503 
FROM #Count 
GROUP BY YY, MM, L_ID 
ORDER BY YY, MM

但我得到以下结果：

YY  MM ID701 ID502 ID18 ID22 ID702 ID503 
2017 1 NULL NULL 2793 NULL NULL NULL 
2017 1 NULL NULL NULL 1407 NULL NULL 
2017 1 NULL 7763 NULL NULL NULL NULL 
2017 1 NULL NULL NULL NULL NULL 608 
2017 1 7919 NULL NULL NULL NULL NULL 
2017 1 NULL NULL NULL NULL 832 NULL 
2017 2 NULL NULL 2874 NULL NULL NULL 
2017 2 NULL NULL NULL 1694 NULL NULL 
2017 2 NULL 7369 NULL NULL NULL NULL 
2017 2 NULL NULL NULL NULL NULL 489 
2017 2 8306 NULL NULL NULL NULL NULL 
2017 2 NULL NULL NULL NULL 778 NULL 
2017 3 NULL NULL 3809 NULL NULL NULL 
2017 3 NULL NULL NULL 2003 NULL NULL 
2017 3 NULL 10368 NULL NULL NULL NULL

至少有进展。有没有办法删除空记录，让他们反而像我想要他们？

编辑2：

作为每@Sean建议，添加以下代码，然后由一个临时表：

SELECT YY 
     ,MM 
     , MAX(Case when L_ID = '701' then TranxCount end) as ID701 
     , MAX(Case when L_ID = '502' then TranxCount end) as ID502 
     , MAX(Case when L_ID = '18' then TranxCount end) as ID18 
     , MAX(Case when L_ID = '22' then TranxCount end) as ID22 
     , MAX(Case when L_ID = '702' then TranxCount end) as ID702 
     , MAX(Case when L_ID = '503' then TranxCount end) as ID503 
INTO #TotCount 
FROM #Count 
GROUP BY YY, MM, L_ID 
ORDER BY YY, MM 

SELECT YY 
    ,MM 
    ,SUM(ID701) 
    ,SUM(ID502) 
    ,SUM(ID18) 
    ,SUM(ID22) 
    ,SUM(ID702) 
    ,SUM(ID503) 

FROM #TotCount 

GROUP BY YY, MM, L_ID 

ORDER BY YY, MM

我得到的错误消息：

无效列L_ID

善良我希望那些不是你真正的表名。呸。错误很明显。至少有一个子查询返回多于一行。 –

我解决了这个问题，方法是创建另一个临时表，然后从第二个临时表中取出一个SUM值，该值取出空值。
我也删除了L_ID的分组。

所以我的代码如下：

SELECT YY 
     ,MM 
     , MAX(Case when L_ID = '701' then TranxCount end) as ID701 
     , MAX(Case when L_ID = '502' then TranxCount end) as ID502 
     , MAX(Case when L_ID = '18' then TranxCount end) as ID18 
     , MAX(Case when L_ID = '22' then TranxCount end) as ID22 
     , MAX(Case when L_ID = '702' then TranxCount end) as ID702 
     , MAX(Case when L_ID = '503' then TranxCount end) as ID503 
INTO #TotCount 
FROM #Count 
GROUP BY YY, MM, L_ID 
ORDER BY YY, MM 

SELECT YY 
    ,MM 
    ,SUM(ID701) 
    ,SUM(ID502) 
    ,SUM(ID18) 
    ,SUM(ID22) 
    ,SUM(ID702) 
    ,SUM(ID503) 

FROM #TotCount 

GROUP BY YY, MM--, L_ID 

ORDER BY YY, MM

此代码的工作，给了我希望的结果。

谢谢@Sean试图帮助。我很感激。

只需从第一组中删除L_ID，而不需要相同数据的其他副本。 –

您可以使用条件聚合来实现此目的。

SELECT YY 
     ,MM 
     , MAX(Case when L_ID = '701' then TranxCount end) as ID701 
     , MAX(Case when L_ID = '502' then TranxCunt end) as ID502 
     , MAX(Case when L_ID = '18' then TranxCount end) as ID18 
     , MAX(Case when L_ID = '22' then TranxCount end) as ID22 
     , MAX(Case when L_ID = '702' then TranxCount end) as ID702 
     , MAX(Case when L_ID = '503' then TranxCount end) as ID503 
FROM #Count 
GROUP BY YY, MM, L_ID 
ORDER BY YY, MM

谢谢@Sean。但你的代码给了我空值（请参阅我的问题编辑）。我将如何删除Null值并将其显示为我想要的值？ – user1777929

从中取出L_ID。 –
