SQLSTATE in Exception Handlers

Dmitry Yemanov

An SQLSTATE code becomes a valid condition for trapping an exception with a WHEN statement. In alignment with SQLCODE and GDSCODE, the SQLSTATE code can be used as in the following snippet:

...
WHEN SQLSTATE '22006' DO
BEGIN
  -- do something
END
...
      

Note

SQLSTATE codes are string literals.
