在MS Access中的选择查询中连接多个数据库

Question

I have three database now I want to retrieve data from 2 tables in different database.

Like wise ledger table in master database, book table in general database.

So first I wrote query like this

 select * 
 from master.ledger, general.book

It show an error.

Could not find file in C:\\Documents and Settings\\MyDocuments...

Then, I wrote a query like this

select * 
from ledger, book IN 'C:\Documents and Settings\User\Desktop\2014\fa.mdb', 
'C:\Documents and Settings\User\Desktop\2014\general.mdb'

It also show an error

'Syntax Error in From Clause'

But If I use single database like

select * 
from ledger IN 'C:\Documents and Settings\User\Desktop\2014\fa.mdb';

it works correctly. How can I connect multiple database in a select query?

Answer 1

Linked tables are the easiest way, but you can also do it like this:

SELECT TblA.*, TblB.* FROM [;DATABASE='C:\Documents and Settings\User\Desktop\2014\fa.mdb'].Master AS tblA
INNER JOIN [;DATABASE='C:\Documents and Settings\User\Desktop\2014\general.mdb'.[General] AS TblB
ON tblA.SomeField=tblB.SomeField

Of course this assumes you have a common field between the two.
