Question I have about this...
DOW GetClient ( ClientNumber );
more code...
ENDO
return only 1 row? If so, then why a cursor? This logic implies you are
passing a client number TO the subprocedure to get information based on
that particular client number. Or, does your open cursor logic also have
some control break logic? Like if the customer number changes close the
cursor and prepare a new statement?
If it doesn't have the control break then this wouldn't be as confusing:
DOW GetClient ();
In general, I like the technique.
I vary on sql code versus sql state. IBM seems to push SQL State as more
portable. There are a few cases where one sql state can mean more than
one sql code and the right sql code will tell you exactly what error
condition you are having. I think it also swings the other way.
