Hi,



I have an old program that produces a file with, amongst other information,
$dossier, profession

The profession has to be changed so it comes from the customer master file.
$customer, profession

To get to the customer master file, I'd have to first access the customer/dossier file
$customer, $dossier

I just wasted an hour updating profession in the old file with profession from the customer master file with SQL. The problem was that there can be more than one dossier per customer.

So I'm going to write an RPG program that reads the old file, chains on customer/dossier file then on customer master file.


Was this possible in SQL?
