sql server - How can I connect to an external database from a sql statement or a stored procedure?

Question

When running a SQL statement or a stored procedure on a database, can you connect to an external database and pull data from there?

something like:

SELECT a.UserID, b.DataIWantToGet 
  FROM mydb.Users as a, externaldb.Data as b

Answer 1

You'll need to setup a Linked Server instance. Then you can reference the external database as though it were a SQL Server database.
