Hi Stan, if the databases are part of the same database servers you can use qualified table names. The example below should explain how to use qualified table names --Create two new test databases create database db1; create database db2; --Create tables in both databases use db1; create table master ( id int, info varchar(255) ); use db2; create table detail values ( id int, masterid int, info varchar(255) ); --create sample data use db1; insert into master values(1, 'master values A'); insert into master values(2, 'master values B'); insert into master values(3, 'master values C'); use db2; insert into detail values(1,1, 'detail values A'); insert into detail values(2,1, 'detail values B'); insert into detail values(3,1, 'detail values C'); insert into detail values(4,2, 'detail values D'); insert into detail values(5,2, 'detail values E'); insert into detail values(6,2, 'detail values F'); insert into detail values(7,3, 'detail values G'); insert into detail values(8,3, 'detail values H'); insert into detail values(9,3, 'detail values I'); --query the sample data select m.id MasterId, d.id DetailId, m.info, d.info from db1.Master m join db2.Detail d on d.masterid=m.id; Hope that helps.
