COBOL DB2 examples always say IF SQLCODE = 0 ... What are the common values I should memorize first?
Thread: DB2
What is SQLCODE and why do people check it after every SQL?

0 = ok
+100 = no row found (not always an error)
negative = real problem (-803 duplicate, -911 deadlock/timeout, -305 null, etc)
Always check it. Ignoring SQLCODE is how you process garbage and smile.

DISPLAY SQLCODE in test when something feels wrong. Cheap debugging.
