edit data

[Otto]

Hello friends,
Editing data is essential for my programs. Therefore, I take some more notes about the logic to remember later how I did it.
There is much new stuff for me with web programming.
You need much time to discover how to do. So, it is better to take notes than start searching from the start.
Best regards,
Otto

Hello friends,
Now we have added a second query. If you want to edit a record, we check whether the data displayed in the browser is still up-to-date.
If not, the editing process is automatically aborted, and you have to refresh the browser first.
Best regards,
Otto
