Update Techniques

The main update technique for bundling database changes in a single database LUW is to use CALL FUNCTION ... IN UPDATE TASK. This section describes various ways of updating the database.

A program can send an update request using COMMIT WORK

• To the update work process, where it is processed asynchronously. The program does not wait for the work process to finish the update ( Asynchronous Update ).
• For asynchronous processing in two steps ( Updating Asynchronously in Steps .)
• To the update work process, where it is processed synchronously. The program waits for the work process to finish the update ( Synchronous Update ).
• To its own work process locally. In this case, of course, the program has to wait until the update is finished ( Local Update .)
