Saving one row per transaction

With primary and secondary collections, you can instruct WinStudio to save each modified row (IDO item) in a separate transaction. When the user executes the save operation on the collection, WinStudio loops through modified rows, executing a Save Current operation for each row. If the save succeeds, WinStudio moves to the next row. If it fails, WinStudio stops and presents an error message. The previous rows remain committed.

In the default behavior, all modified rows are sent to the middle tier to be processed within a single transaction, which is rolled back if there is a failure.

注意：If your form design requires that all modified rows be committed as a unit, with processing on the unit before and/or after a save operation, saving rows in separate transactions might not be appropriate: If an error occurs on a row, some rows might be committed and others not committed.
