Re: How does a SQL result set return pack fields to the caller

This is exactly correct - it might even be an RPG thing to allow using data structures for at most 1 result set, IIRC - nonetheless, it's not sent out as a single stream of bytes, as in a data structure.

​If by calling program, you mean the ​invoker of the stored procedure, then
no it doesn't get a blob of data it has to parse out.

The DB "breaks" the data into rows & columns before returning it as a
results set.

AFAIK, the neither the ODBC/JDBC driver nor the calling program see any
difference from a RS created from an RPG array/MODS and one created by a
SQL cursor.
