无法获得数据行

Question

无法绑定多部分标识符“tblTask​​.Id”。 我错了什么？

SELECT SUM(CAST(Value as int)) FROM [tblExtraFieldData] 
WHERE [tblExtraFieldData].[FieldId] = '10010' 
AND [tblExtraFieldData].[OwnerId]=[tblTask].[Id] 
AND [tblTask].[Status]=4 
AND [tblTask].[CustomA3]='Bygg'

Answer 1

试试这个

SELECT SUM(CAST(Value as int)) FROM [tblExtraFieldData]  tble
INNER JOIN tblTask tblt ON tble.[OwnerId]=tblt.[Id] 
WHERE tble.[FieldId] = '10010'     
AND tble.[Status]=4 
AND tble.[CustomA3]='Bygg'

OR

SELECT SUM(CAST(Value as int)) FROM [tblExtraFieldData],[tblTask]
WHERE [tblExtraFieldData].[FieldId] = '10010' 
AND [tblExtraFieldData].[OwnerId]=[tblTask].[Id] 
AND [tblTask].[Status]=4 
AND [tblTask].[CustomA3]='Bygg'

可能使用第一个。
