Oracle Forms Developer – Form Builder Reference, Volume 1

LOCK_RECORD built-in
Description
Attempts to lock the row in the database that corresponds to the current record. LOCK_RECORD locks
the record immediately, regardless of whether the Locking Mode block property is set to Immediate (the
default) or Delayed.
When executed from within an On-Lock trigger, LOCK_RECORD initiates default database locking.
The following example illustrates this technique.
Syntax
PROCEDURE LOCK_RECORD;
Built-in Type unrestricted procedure
Enter Query Mode no
Parameters
none

/*
** Built-in: LOCK_RECORD

** updated. Decide whether to use default
** processing or a user exit by consulting a
** global flag setup at startup by the form,
** perhaps based on a parameter.
** trigger: On-Lock
