SQLWARNING Keyword
If you use the SQLWARNING keyword, any SQL statement
that generates a warning is handled as the WHENEVER SQLWARNING statement
directs. If a warning occurs, the first field (sqlca.sqlwarn.sqlwarn0)
of the warning structure in SQLCA is set to W
, and
the SQLSTATE variable is set to a class code of 01
.
Besides the first field of the warning structure, a warning
also sets an additional field to W
. The field that
is set indicates what type of warning occurred.
The next statement causes execution to stop if a warning
condition exists:
WHENEVER SQLWARNING STOP
If you do not use any WHENEVER SQLWARNING statements in a program, the default action for WHENEVER SQLWARNING is CONTINUE.
