Oracle Forms Developer – Form Builder Reference, Volume 1

VALIDATE built-in
Description
VALIDATE forces Form Builder to immediately execute validation processing for the indicated
validation scope.
Syntax
VALIDATE
(validation_scope NUMBER);
Built-in Type:
unrestricted procedure
Enter Query Mode yes
Parameters
validation scope Specify one of the following scopes:
Note on runtime behavior
DEFAULT_SCOPE Perform normal validation for the default scope,
determined by the runtime platform.
Note: If you change the scope via
SET_FORM_PROPERTY(VALIDATION UNIT) and then call
VALIDATE(DEFAULT_SCOPE), you will override the default scope as
defined in the form module. In this case, Form Builder will not validate at
the default scope but at the scope defined by SET_FORM_PROPERTY.
FORM_SCOPE Perform normal validation for the current form.
BLOCK_SCOPE Perform normal validation for the current block.
RECORD_SCOPE Perform normal validation for the current record.
ITEM_SCOPE Perform normal validation for the current item.
If an invalid field is detected when validation is performed, the cursor does not move to that field.
Instead, the cursor remains in its previous position.

/*
** Built-in: VALIDATE
