Default Handling of Errors and Warnings in Procedures

Errors and warnings are handled differently in procedures.

The default action for errors is to set a value for the SQLSTATE and SQLCODE variables, and return control to the calling environment in the event of an error, the default action for warnings is to set the SQLSTATE and SQLCODE values and continue execution of the procedure.
