The FETCH statement is expected to return no rows eventually, so when that happens, no exception is raised. THEN -- handle the error WHEN OTHERS THEN -- handle all other errors END; If you want two or more exceptions to execute the same sequence of statements, list the exception

Raising Exceptions with the RAISE Statement PL/SQL blocks and subprograms should raise an exception only when an error makes it undesirable or impossible to finish processing. Declaring PL/SQL Exceptions Exceptions can be declared only in the declarative part of a PL/SQL block, subprogram, or package. Summary of Predefined PL/SQL Exceptions An internal exception is raised automatically if your PL/SQL program violates an Oracle rule or exceeds a system-dependent limit. But nicely put together.

With many programming languages, unless you disable error checking, a run-time error such as stack overflow or division by zero stops normal processing and returns control to the operating system. share|improve this answer edited Nov 19 '09 at 10:39 answered Nov 19 '09 at 7:11 APC 87.4k1384184 +1 Very explanatory.
