Query a database based on result of query from another database

Question

I am using SSIS in VS 2013. I need to get a list of IDs from 1 database, and with that list of IDs, I want to query another database, ie SELECT ... from MySecondDB WHE

Answer 1

You could add a LinkedServer between the two servers. The SQL command would be something like this:

EXEC sp_addlinkedserver @server='SRV' --or any name you want
EXEC sp_addlinkedsrvlogin 'SRV', 'false', null, 'username', 'password'

SELECT * FROM SRV.CatalogNameInSecondDB.dbo.SecondDBTableName s
INNER JOIN FirstDBTableName f on s.ID = f.ID
WHERE f.ID IN (list of values)

EXEC sp_dropserver 'SRV', 'droplogins'
