Re: SQL Across Multiple AS400's

Is a trigger solution acceptable ?
Suppose you put a trigger on the right files, and progage the change to a
DDM file (based on a file in a central system)
Suppose that the central file has the same structure that the local one +
the system name.
On the central side, you will get in real time  or not far, all transaction
in one file, after that you can just assign each system names to a compagny
name and make a local SQL process agains the central file.

Not sure if i a am clear... poor english sorry.

The problem is I have an inquiry program written across files in multiple
libraries(1 per company) and we now have bought another company aand for

the

next year or so, the inquiry needs to select employee records from 24
different companies, 12 or so on each as400.
Further complicating the problem, is the fact that the program uses SQL
entirely, so no DDM files, unless I rewrite the program to use RPG.
This is all possible, I am just trying to avoid it.

The program gets transactions from any company that an employee has worked
for and displays the results in a subfile.

Any help is greatly appreciated.

Thanks
Tom

You could create DDM files.  I really don't know much at all about DDM
files, but they are like pointers to a file on another system I guess,
but you treat them as a normal file.  Can't SQL DDM files though.  I
also don't know if you can have multiple DDM files, each pointing to a
different system.  Something to look into though.

Does anyone have an example of how to get information from files from
multiple AS400's with SQL ?
Thanks
