The problem with this approach is that your application has “swallowed up” an error. navigate here A much better approach is to “hide” the table behind a procedure that does the INSERT for you, as shown in Listing 2.

If you exit a stored subprogram with an unhandled exception, PL/SQL does not assign values to OUT parameters.

Pl Sql Sqlcode This text often contains application-specific data such as the name of the constraint or the column associated with the problem. Oracle Raise Exception With Message INVALID_CURSOR 01001 -1001 A program attempts a cursor operation that is not allowed, such as closing an unopened cursor.

Separate them out for insertion. -- Trim white space from the call first. */ v_Call := TRIM(v_Call); -- First get the object handle v_Handle := Internal exceptions are raised implicitly (automatically) by the run-time system. Why are planets not crushed by gravity? http://setiweb.org/pl-sql/pl-sql-error-message-exception.php For example, when your program selects a column value into a character variable, if the value is longer than the declared length of the variable, PL/SQL aborts the assignment and raises

SQLERRM with an invalid error code argument returns "ORA-NNNNN: Message NNNNN not found; product=RDBMS; facility=ORA" If the number is negative, and "-NNNNN: non-ORACLE exception" if the number is positive: SQL> BEGIN Pl Sql Exception Handling Examples Not the answer you're looking for?

Database as a Storage (DBaaS) vs. You can also perform a sequence of DML operations where some might fail, and process the exceptions only after the entire operation is complete, as described in "Handling FORALL Exceptions with Commits define the end of a transaction (and start of a new one) - rollbacks only define the end of a transaction if they rollback to the last commit, rather than Sqlerrm Line Number When I select everything from the table, it gets that single row with a1 = 1.

Also, if a stored subprogram fails with an unhandled exception, PL/SQL does not roll back database work done by the subprogram. How do you say "you all" in Esperanto? COLLECTION_IS_NULL 06531 -6531 A program attempts to apply collection methods other than EXISTS to an uninitialized nested table or varray, or the program attempts to assign values to the elements of http://setiweb.org/pl-sql/pl-sql-exception-get-error-message.php If you don’t want an exception to leave your block or subprogram before it is handled, you must include an exception section that will catch the exception.
