I'm working with iSeries V5. I have a table that I have to insert rows selected from another table. But I also...
have to put row numbers for each inserted row, because more than one user has to use this application. Can you advise me on how to accomplish this?
There's a new ROWID data type in V5R2 that can be used to have DB2 generate a 40-byte unique identifier for each new row in a table. You might also consider writing a Before Insert trigger that "intercepts" the insert request and computes a unique identifier for that row.
