Release 10.1A: OpenEdge Development:
Progress 4GL Reference

AUTO-SYNCHRONIZE attribute

Indicates whether Progress automatically synchronizes a hierarchy of queries on a ProDataSet temp-table buffer.

Data type: LOGICAL

Access: Readable/Writeable

Applies to: Buffer object handle

Set to TRUE to synchronize the related buffers automatically. The default is FALSE.

When AUTO-SYNCHRONIZE is TRUE and a new row is placed in the buffer, the synchronize action occurs. The event handler is called when the buffer has a CREATE, DELETE, RELEASE, FIND, FOR-EACH, QUERY GET, or BUFFER-COPY run on it.

If the BUFFER-COPY is part of a FILL operation, a before-image operation (such as SAVE-ROW-CHANGES), or a deep-copy during parameter passing or COPY-TEMP-TABLE, then the synchronize action does not occur.

If you perform a manual FILL operation using BUFFER-COPY, you can prevent the query hierarchy from being synchronized unnecessarily by setting the AUTO-SYNCHRONIZE attribute to FALSE.
