如何从SQL Server Management Studio中的两个不同服务器和数据库中选择同一查询中的数据？

Question

如何从两个不同服务器（一个DB2服务器和另一个SQL Server）上的两个不同数据库中选择同一查询中的数据？

Answer 1

On your sql server, set up a linked server to the db2 database.

Then write your query on sql server. I suggest that you use openquery for the db2 stuff. If you have to combine the data, populate a sql server temp table with the openquery results and work from there.

The reason I suggest this is performance. I have found that if you use this syntax

select somefields
from server.database.owner.table
where whatever

sql server will bring back the entire table from the linked server and apply the where clause afterwards.
