Sql 透视到多列

我对3个表中的1列受影响的_项进行了查询

如何对受影响的两列\u ITEM和ASSIGN执行相同的查询

这是对3个表的1列受影响的_项的查询

SELECT
 AFFECTED_ITEM,
   Table1,
   Table2,
   Table3

FROM (
SELECT  'Table1' as Tab, AFFECTED_ITEM, Count(*) as AFFECTED_ITEMS from [dbo].[CM3RM1] WHERE ORIG_DATE_ENTERED between (@StartDate) and @EndDate + 1
and [AFFECTED_ITEM] in (@Affected_Item) and [COMPANY] in (@Company) and [ASSIGNED_TO] in (@Assignee) group by AFFECTED_ITEM
UNION ALL
SELECT  'Table2' as Tab, AFFECTED_ITEM, Count(*) as AFFECTED_ITEMS from [dbo].[INCIDENTSM1]  WHERE  OPEN_TIME between (@StartDate) and @EndDate + 1
and [AFFECTED_ITEM] in (@Affected_Item) and [COMPANY] in (@Company) and [ASSIGNEE] in (@Assignee) group by AFFECTED_ITEM
UNION ALL
SELECT  'Table3' as Tab, AFFECTED_ITEM, Count(*) as AFFECTED_ITEMS from [dbo].[PROBSUMMARYM1] WHERE  OPEN_TIME between @StartDate and @EndDate + 1
and [AFFECTED_ITEM] in (@Affected_Item) and [COMPANY] in (@Company)and  [ASSIGNEE_NAME] in (@Assignee) and [DDC_RESP_COMPANY] in (@Resp_Company) group by AFFECTED_ITEM
 ) t
PIVOT (SUM(AFFECTED_ITEMS) FOR Tab IN (Table1,Table2,Table3)
)as p

这是针对“1列受影响的\u项到3个表”的查询，还是针对“2列受影响的\u项和分配的相同请求”的尝试查询？这是针对1列受影响的\u项到3个表的查询您在中的

没有做您认为会做的事情。
