LUPDATE()
Return the last modification date of a database (.dbf) file
------------------------------------------------------------------------------
Syntax
LUPDATE() --> dModification
Returns
LUPDATE() returns the date of the last change to the open database file
in the current work area. If there is no database file in USE,
LUPDATE() returns a blank date.
Description
LUPDATE() is a database function that determines the date the database
file in the current work area was last modified and CLOSEd. By default,
LUPDATE() operates on the currently selected work area. It will operate
on an unselected work area if you specify it as part of an aliased
expression, as shown in the example below.
Examples
. This example demonstrates that the modification date of the
database file is not changed until the database file is closed:
? DATE() // Result: 09/01/90
USE Sales NEW
? LUPDATE() // Result: 08/31/90
//
APPEND BLANK
? LUPDATE() // Result: 08/31/90
CLOSE DATABASES
//
USE Sales NEW
? LUPDATE() // Result: 09/01/90
. This example uses an aliased expression to access LUPDATE()
for a database file opened in an unselected work area:
USE Sales NEW
USE Customer NEW
? LUPDATE(), Sales->(LUPDATE())
Files Library is EXTEND.LIB.
