Re: Returning Record Sets from SQLRPGLE Web Services

Depending on when\how the rows could be /lost/. Certainly the same issue exists when an OVERRIDE SYSTEM DEFAULT is used to place a row into an existing hole in the sequence for the identity. For the report scenario, I still do not see much of an issue; active data could be missed for timing just as well as for RRN and using previously deleted values.

would not have that issue.

I wonder though, what would all of the overhead of an IDcol achieve
that a RRN() could not, for the same scenario? The relative row
number is a similarly arbitrary value, as compared to an identity.
