I have a file (err um "table") where I'm inserting a row. I need to increment a sequence number based on the values of 3 other fields.
1. If there aren't any rows for a given order number, the sequence would be 1
2. If there are rows for a given order number, I need the "next" sequence number
Currently I run Exec SQL to get the max(seq#), add one to that in RPG, and then Exec SQL and insert the row.
Just wondering if a different (more clever) method exists?
Side Note: There can be multiple users inserting rows simultaneously - this has me concerned for my method.
