DELETE RECORD


DELETE RECORD {( aTable )}

Parameter	Type	Description
aTable	Table	Table where the current record will be deleted, or Default table, if omitted

Description

DELETE RECORD deletes the current record of aTable in the process. If there is no current record for aTable in the process, DELETE RECORD has no effect. In a form, you can create a Delete Record button instead of using this command.

Notes:

If the current record is unloaded from memory before calling DELETE RECORD (for example, subsequent to an UNLOAD RECORD), the current selection of table is empty after the deletion occurs.
The DELETE RECORD command does nothing when the table is in READ ONLY mode, regardless of whether the record to be deleted is locked or not.

Deleting records is a permanent operation and cannot be undone.

If a record is deleted, the record number will be reused when new records are created. Do not use the record number as the record identifier if you will ever delete records from the database.

Example

The following example deletes an employee record. The code asks the user what employee to delete, searches for the employee’s record, and then deletes it:

 vFind:=Request("Employee ID to delete:") ` Get an employee ID

 If(OK=1)

    QUERY([Employee];[Employee]ID =vFind) ` Find the employee

    DELETE RECORD([Employee]) ` Delete the employee

 End if
