Delete Record
-------------
Deleting record(s) via QFQ might be solved by either:
* using the `delete` button on a form on the top right corner.
* by letting `report`_ creating a special link (see below). The link contains the record id and:
* a form name, or
* a table name.
Deleting a record just by specifying a table name, will only delete the defined record (no slave records).
* By using a delete button via `report` or in a `subrecord` row, a ajax request is send.
* By using a delete button on the top right corner of the form, the form will be closed after deleting the record.
Example for report::
SELECT p.name, CONCAT('form=person&r=', p.id) AS _Paged FROM Person AS p
SELECT p.name, CONCAT('table=Person&r=', p.id) AS _Paged FROM Person AS p
To automatically delete slave records, use a form and create `beforeDelete` FormElement(s) on the form:
* class: action
* type: beforeDelete
* parameter: sqlAfter={{DELETE FROM <slaveTable> WHERE <slaveTable>.<masteId>={{id:R}} }}
You might also check the form 'form' how the slave records 'FormElement' will be deleted.
