TsgcWSPServer_Dataset › Properties › UpdateMode
Strategy used to match an incoming update against a row in the server dataset.
property UpdateMode: TwsDatasetUpdateMode read FUpdateMode write FUpdateMode;—
Controls how the server locates the affected row when a client sends an update or delete. upWhereAll (the default) requires every old field value to match, mimicking optimistic locking; upWhereKeyOnly matches on the primary key fields only; upWhereChanged matches on the primary key plus the fields actually being changed; upRefreshAll ignores row matching and rebroadcasts the entire dataset when it is refreshed.
oProtocol.UpdateMode := upWhereKeyOnly;
