Named system exceptions are: 1) Not Declared explicitly, 2) Raised implicitly when a predefined Oracle error occurs, 3) caught by referencing the standard name within an exception-handling routine. SELECT error_seq.nextval INTO v_SeqNum FROM DUAL; p_SeqNum := v_SeqNum; -- Insert first part of header info. Before starting the transaction, mark a savepoint. The invoker does not handle the exception, so PL/SQL returns an unhandled exception error to the host environment. click site

COLLECTION_IS_NULL Your program attempts to apply collection methods other than EXISTS to an uninitialized (atomically null) nested table or varray, or the program attempts to assign values to the elements of Im getting Invalid SQL statement while giving CODE above procedure.

That is, the exception reproduces itself in successive enclosing blocks until a block has a handler for it or there is no enclosing block (for more information, see "Exception Propagation"). ROWTYPE_MISMATCH The host cursor variable and PL/SQL cursor variable involved in an assignment have incompatible return types.
