Testing if a trigger event is INSERT.


Syntax

<inserting predicate> ::= INSERTING


Notes

♦ The INSERTING predicate can only be specified in the body of a trigger definition to check the trigger event.
♦ The predicate evaluates to TRUE if the trigger was activated by an INSERT operation on the table, else to FALSE.


Examples

1) The following example shows how the INSERT predicate is used in the WHEN clause of a triggered action:

       WHEN ( INSERTING )

       triggered SQL statements

2) The following example shows how the INSERT predicate is used in a triggered SQL statement:
