SQL老外连接转换； SQL Server 2012 不支持 operator =*

Question

请帮我将此查询转换为 SQL Server 2012。SQL Server 2012 不支持运算符 =*：

select 
    Sum(ISNULL(Qty_Recd,0.00)) as Qty_Recd, a.PR_Detail_Key
from 
    PO_Dely c, PO_Tracking1 a
where 
    c.PO_Key =* a.PO_Key 
    and PR_No = '123456' 
    and a.File_Type = 72 
    and c.File_Type = 72
group by 
    a.PR_Detail_Key 
order by 
    a.PR_Detail_Key

Answer 1

您想转向显式连接语法。试试这个：

select 
    Sum(ISNULL(Qty_Recd,0.00)) as Qty_Recd
    , a.PR_Detail_Key 
from PO_Dely as c
    right outer join PO_Tracking1 as a 
        on c.PO_Key = a.PO_Key 
where PR_No = '123456' 
    and a.File_Type = 72 
    and c.File_Type = 72 
group by a.PR_Detail_Key 
order by a.PR_Detail_Key
