Betreff: sqlrpgle question
Hi,
I want to set the value of an indicator to *on if I find at least one record
matching my search criteria and *off otherwise.
What's the best way?
eg :
indicator = *off;
exec sql
Select '1' into : indicator
from mytable
where ....err.. what goes here? what if there are many rows returned?
Thanks!
