Re: RPG - MsSQL Connection

Just to be clear.. it might be possible to join two DB2 tables from separate systems, or two SQL Server tables from separate systems... but you'll never be able to join a SQL Server table to a DB2 Table.

Why not? Because they're handled by separate query engines. The DB2 query engine doesn't know how to use a SQL Server table or index. The SQL Server query engine doesn't know how to use a DB2 table or index.

Just wondering how to handle the need to join a remote table to a local
table? As an example, perhaps I need to retrieve rows from a MS-SQL
Server, then update a local table to match the remote. If using
ARDgate, would I need to connect to the remote, then make a copy into a
local temp table, then connect to the local DB2 to process the update
statement? I understand that DB2 Multisystem could handle concurrent
access (federated DB), but otherwise is not supported on IBM i.
