DATA-SOURCE-ROWID attribute

Identifies the data-source row corresponding to the buffer object handle.

Data type: ROWID

Access: Readable/Writeable

Applies to: Buffer object handle

This attribute locates the data-source row corresponding to either an after-table buffer or a before-table buffer. The portion of the SAVE-ROW-CHANGES( ) method that locates the appropriate data-source row is used to produce a ROWID for users who want to either make their own version of SAVE-ROW-CHANGES( ) or access the source record in some way before or after SAVE-ROW-CHANGES( ).

Syntax

DATA-SOURCE-ROWID( { join level | buffer name } )

join level

An integer expression that evaluates to the level of join, if the data-source is a join.

buffer name

A character expression that evaluates to the name of one of the data-source buffers.
