所以这是我的设置,我有2个具有以下(简化)模式的旧表和新表
Old [ManName] [ManNumber] New [Manager_Name] [Manager_Number]
我正在寻找一种SQL查询,该查询返回以下内容,但在1个查询中包含4列,而不是每个2列包含2个查询
select distinct manname, mannumber from OLD select distinct Manager_Name, Manager_Number from NEW
因此,我理想的结果集将包含4列:
ManName ManNumber Manager_Name Manager Number
谢谢!
您是否尝试过JOIN语句:
select distinct * from old a join new b on a.ManName = b. Manager_Name and a. ManNumber = b. Manager_Number
