Hi Erol,
I am using Basex 7.9 and my script is running well. I can not use 8.0 because I have tested script with it , it can not finish.
Do you mean that the script does not work with the 8.0 snapshot? Do you have more information?
How difficult to back port sql changes to Basex 7.9 branch?
It's not difficult per se, but it mainly takes time (we haven't added any features to 7.9 so far).
Best, Christian
