MS Access / SQL-连接两个表

Question

我有两个表tbl_sbc和tbl_jdf，两个表都有Users和Access字段。 我想基于来自tbl_sbc和tbl_jdf的用户相等性创建一个新表，并对访问进行总结。

例

tbl_sbc

User Access
Foo  20
Bar  5

tbl_jdf

User Access
Foo 35
Beef 50

输出量

User Access
Foo  55
Bar  5
Beef 50

我将如何去做？ 我似乎无法总结这些价值

Answer 1

干得好

Select User, Sum(Access) As Total from
(Select User , Access from tbl_sbc
Union All
Select User , Access from tbl_jdf)
Group by User
order by user desc
