I worked on my problem a little further and have a little more
information to share. The declare statement that fails consistently
follows a select statement that returns zero rows (and sqlcode 100 and
sqlstate '02000'). If I ommit the select statement from the code or set
sqlcode to 0 before calling the declare statement, the declare statement
works fine.
It appears as though the declare statement is not updating the sqlca
structure. Is this by design for the ecpg options that I'm using? Did I
pick up bad habits while using Informix?
Thanks ...
