Table joins across databases

P: 1
Hello,

Can someone tell me how one would join tables across different databases, the databases being in the same instance.

select <field> from database1.table1 a, database2.table1 b
where a.key=b.key

does not seem to work

This is not possible without federated environment.

You can try some alternatives like: Export from one table(first database in PC/IXF format), create GTT in second database, import in this GTT and perform select.

You might want to have a look at the sample SQLLIB/samples/c/dbmcon.sqc. This samples demonstrates how to use two databases simultaneously.

Let me know if your problem is solved.
