Oracle Forms Developer – Form Builder Reference, Volume 1

Post-Query trigger
Description
When a query is open in the block, the Post-Query trigger fires each time Form Builder fetches a record
into a block. The trigger fires once for each record placed on the block’s list of records.
Definition Level form or block
Legal Commands
SELECT statements, unrestricted built-ins
Enter Query Mode no
Usage Notes
Use a Post-Query trigger to perform the following tasks:
• populate control items or items in other blocks
• calculate statistics about the records retrieved by a query
• calculate a running total
• When you use a Post-Query trigger to SELECT non-base table values into control items, Form
Builder marks each record as CHANGED, and so fires the When-Validate-Item trigger by default.
You can avoid the execution of the When-Validate-Item trigger by explicitly setting the Status
property of each record to QUERY in the Post-Query trigger. To set record status
programmatically, use SET_RECORD_PROPERTY .
On Failure
Form Builder flushes the record from the block and attempts to fetch the next record from the database.
If there are no other records in the database, Form Builder closes the query and waits for the next
operator action.
