If SqlServer doesn't support locking of rows for update, I wonder how MySql
will handle this when it is shoehorned onto the iSeries? Will RPG be able
to access the MySql database directly? This could prove very interesting.

too bad. it is an interesting topic. from what I am seeing of
sqlServer, the concept of selecting a row for update, doing some
calcs, and then updating the locked row is not supported. The reason
being that it is contrary to the disconnected database and network
model of application programming that MSFT has embraced.

RPG code makes heavy use of what I think is called optimistic locking.
How would you port RPG code that wants to read records, lock them
and then update?
