LAST SUBRECORD


LAST SUBRECORD ( subtable )

Parameter	Type	Description
subtable	Subtable	Subtable in which to move to the last selected subrecord

Compatibility note

Subtables are no longer supported starting with version 11 of 4D. A compatibility mechanism ensures the functioning of this command in converted databases; however, it is strongly recommended to replace any subtables with standard related tables.

Description

LAST SUBRECORD makes the last subrecord of the current subselection of subtable the current subrecord. If the current subselection is empty, LAST SUBRECORD has no effect.

Example

The following example concatenates the first and last names in child records stored in a subtable. It copies the names into an array, called atNames. It is the same as the example for FIRST SUBRECORD except that it moves through the subrecords from last to first:

  ` Create an array to hold the names

 ARRAY TEXT(atNames;Records in subselection([People]Children))

 LAST SUBRECORD([People]Children) ` Start at the last subrecord and loop once for each child

 For($vlSub;1;Records in subselection([People]Children))

    atNames{$vlSub}:=[People]Children First Names+" "+[People]Children Last Names

    PREVIOUS SUBRECORD([People]Children)

 End for
