what's the "right" way of doing this after execution of the sql statement?
Use sql count() and check for 0?
Get the condition of the first line that doesn't satisfy the search
criteria and check that?
Ignore all the host variables and check for sqlcode = 100?
I think this is highly dependent on the scenario, but I'll share my
methodology as a starting place for discussion.
exec sql fetch...
select;
when sqlstate = SQLNoData
...
when sqlstate = SQLNormal
...
when sqlstate = SQLTrunc
...
// unexpected error needs further diagnosis
other
dump(a) 'unique eyecatcher'
// email message to programming staff
// create user-friendly message for end user
endsl;
SQLSTATE has the advantage that the first two characters are the 'class'
of the result. '00' are 'normal', '01' are 'warning', etc. Depending on
the kind of granularity you want, this is very cool.
