An exception can be either internally defined (by the run-time system) or user-defined. Examples of internally defined exceptions are user defined exception in pl sql ORA-22056 (value string is divided by zero) and ORA-27102 (out of memory). Some common internal exceptions have predefined names, such as ZERO_DIVIDE and STORAGE_ERROR. The other internal exceptions can be given names. You can define your own exceptions in the declarative part of any PL/SQL block, subprogram, or package. For example, you might define an exception named insufficient_funds to flag overdrawn bank accounts. User-defined exceptions
Pl Sql Exception When Others
must be given names. When an error occurs, an exception is raised. That is, normal execution stops and control transfers to the exception-handling part of your PL/SQL block or subprogram. Internal exceptions are raised implicitly (automatically) by the run-time system. User-defined exceptions must be raised explicitly by RAISE statements or invocations of the procedure DBMS_STANDARD.RAISE_APPLICATION_ERROR. To handle raised exceptions, you write separate routines called exception handlers. After an exception handler runs, the current block stops executing and the enclosing block resumes with the next statement. If there is no enclosing block, control returns to the host environment. For information about managing errors when using BULK COLLECT, see Handling FORALL Exceptions (%BULK_EXCEPTIONS Attribute). Example 11-1 calculates a price-to-earnings ratio for a company. If the company has zero earnings, the division operation raises the predefined exception ZERO_DIVIDE, the execution of the block is interrupted, and control is transferred to the exception handlers. The optional OTHERS handler catches all exceptions that the block does not name specifically. Example 11-1 Run-Time Error Handling DECLARE stock_price NUMBER := 9.73; net_earnings NUMBER := 0; pe_ratio NUMBER; BEGIN -- Calculation might cause division-by-zero error. pe_ratio := stock_price / net_earnings; DBMS_OUTPUT.PUT_LINE(

Are you sure you are running that version? –angus May 5 '11 at 20:08 By the way, see here: stackoverflow.com/questions/177752/… –angus May 5 '11 at 20:09 @angus - We are on 10g, bummer. Guess I'll just use a NULL; and a bunch of conditional IF statements to help with the loop. Post your answer as a reply and I'll mark it as the correct answer. –ProfessionalAmateur May 5 '11 at 20:16 Done, thanks. Look at that other question, maybe you can just use GOTO. –angus May 5 '11 at 20:21 2 A simpler solution would be to loop through a query that joins the two tables - then you wouldn't have to handle any exceptions. –Adam Musch May 6 '
