Copy rows across to another db

Hello all,

first of all please forgive me for asking what might turn out to be a very stupid question. I am new to SQL.

Here is my problem. I have to identical databases, one used for testing (db_test), the other for production (db_prod). What I want to do is to grab a row from a table in db_test and insert it into the relative table into db_prod.

Now, I know to use INSERT INTO, however I having problems specifiying which database to select from and which to insert to. I have tried specifying the full path ([db_test].[dbo].[Table1]) but it does not work. I can only get statements to work if is include the "USE [db_test]" line at the top, but I can't then access the other db.

Any suggestions?It is surprising that the cross database INSERT does not work. Perhaps you could post the query so I could see is there is an error?
