Oracle Forms Developer – Form Builder Reference, Volume 1

When-Clear-Block trigger
Description
Fires just before Form Builder clears the data from the current block.
Note that the When-Clear-Block trigger does not fire when Form Builder clears the current block during
the CLEAR_FORM event.
Definition Level form or block
Legal Commands
SELECT statements, unrestricted built-ins
Enter Query Mode yes
Usage Notes
• Use a When-Clear-Block trigger to perform an action every time Form Builder flushes the current
block. For example, you might want to perform an automatic commit whenever this condition
occurs.
• In a When-Clear-Block trigger, the value of SYSTEM.RECORD_STATUS is unreliable because
there is no current record. An alternative is to use GET_RECORD_PROPERTY to obtain the
record status. Because GET_RECORD_PROPERTY requires reference to a specific record, its
value is always accurate.
On Failure
no effect on the clearing of the block
