I suspect its something related to the sessions? database sessions.
The SQL its alright, I logged the SQL and works fine.
SESSION_DRIVER=database
SESSION_LIFETIME=30
- Operating System: Linux
- PHP Version: 7.4
- Laravel Version: 7
- Laravel-Datatables Version: 9
Just ignore this. Was killing the hanging MySQL process and that error come out.
The problem was a subquery in te select statement, I hope making the joins and just putting the transformation in the select will work.
☕ Thanks
