Release 10.1A: OpenEdge Development:
ADM Reference

deleteBuffer

Deletes the current record of a query’s buffer from the database. Returns TRUE when it succeeds and FALSE if it fails.

Location: wbdata.p

Parameters:

INPUT Buffer AS HANDLE

The current record’s buffer handle.

Returns: LOGICAL

Notes:

This function is only used when the data-source is a database.
It is called from deleteRow, inside of the transaction block, for each of the query buffers returned by the DeleteTables property.
The default function uses the BUFFER–DELETE method on the passed handle.
The main purpose of deleteBuffer is to override BUFFER–DELETE for the deletion of a particular table. This is necessary when a table has a schema validation. The BUFFER–DELETE that usually deletes dynamic buffer records does not delete these tables. The AppBuilder detail wizard will generate the necessary override function in the target–procedure’s source.
A message will be added to the ADM 2 message queue if the delete fails.
