Include a counter variable in your package to detect this situation.

A relational database does not guarantee the order of rows processed by a SQL statement.

Any view that contains one of those constructs can be made updatable by using an triggers can also be created over nested table view columns. All of these sections can access a common PL/SQL state.

These triggers provide a way of updating elements of the nested table. The common state is established when the triggering statement starts and is destroyed when the triggering statement completes, even when the triggering statement causes an error.

If a timing-point section is absent, nothing happens at its timing point.

A timing-point section cannot be enclosed in a PL/SQL block.

A column list cannot be specified for statement trigger fires again.

The rollback to savepoint does not undo changes to any package variables referenced in the trigger.

The object privileges to the schema objects referenced in the trigger body must be granted to the trigger owner explicitly (not through a role).This type of trigger also provides an additional correlation name for accessing the parent row that contains the nested table being modified. SQL (the first part) declares variables and subprograms that timing-point sections can use.When the trigger fires, the declarative part executes before any timing-point sections execute.They fire for each nested table element being modified. CREATE OR REPLACE TRIGGER compound_trigger 2 FOR UPDATE OF salary ON employees 3 COMPOUND TRIGGER 4 5 -- Declarative part (optional) 6 -- Variables declared here have firing-statement duration.The row correlation variables inside the trigger correspond to the nested table element. 7 threshold CONSTANT SIMPLE_INTEGER := 200; 8 9 BEFORE STATEMENT IS 10 BEGIN 11 NULL; 12 END BEFORE STATEMENT; 13 14 BEFORE EACH ROW IS 15 BEGIN 16 NULL; 17 END BEFORE EACH ROW; 18 19 AFTER EACH ROW IS 20 BEGIN 21 NULL; 22 END AFTER EACH ROW; 23 24 AFTER STATEMENT IS 25 BEGIN 26 NULL; 27 END AFTER STATEMENT; 28 END compound_trigger; 29 / Trigger created.

A trigger defined on a schema fires for each event associated with the owner of the schema (the current user).
