CREATE SUBRECORD


CREATE SUBRECORD ( subtable )

Parameter	Type	Description
subtable	Subtable	Subtable for which to create a new 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

CREATE SUBRECORD creates a new subrecord for subtable and makes the new subrecord the current subrecord. The new subrecord is saved only when the parent record is saved. The parent record can be saved by a command such as SAVE RECORD or by the user accepting the record. If there is no current record, CREATE SUBRECORD has no effect. To add a new subrecord through a subrecord input form, use ADD SUBRECORD.

Example

The following example is an object method for a button. When it is executed (that is, when the button is clicked), it creates new subrecords for children in the [People] table. The Repeat loop lets the user add children until the Cancel button is clicked. The form displays the children in an subform, but will not allow direct data entry into the subtable because the Enterable option has been turned off:

 Repeat

  ` Get the child’s name

    vChild:=Request("Name (cancel when done):")

  ` If the user clicked OK

    If(OK=1)

  ` Add a new subrecord for a child

       CREATE SUBRECORD([People]Children)

  ` Assign child’s name to the subfield

       [People]Children'Name:=vChild

    End if

 Until(OK=0)
