Progress 4GL Reference

MERGE-BY-FIELD attribute

Specifies whether Progress merges changes on a field-by-field basis when saving changes from a ProDataSet temp-table buffer to the associated data source using the SAVE-ROW-CHANGES( ) method. The default value is TRUE.

Note: Merging a large number of changes from a ProDataSet object to the data source on a field-by-field basis is slower than saving changes buffer-by-buffer.

Data type: LOGICAL

Access: Readable/Writeable

Applies to: Data-source object handle

If TRUE, Progress performs a field-to-field comparison to identify data conflicts. In this case, a data conflict exists when the same field in the ProDataSet buffer and its associated data source buffer has changed. A data conflict would not exist if a different field had changed in either buffer.

If FALSE, Progress performs a buffer-to-buffer comparison to identify data conflicts. In this case, a data conflict exists when any field in the data source buffer has changed.
