issue with converting stored procedure from Oracle to MariaDB

Hi All,

I want immediate help to convert below stored procedure from oracle to Maria DB .
please help me out.

what is equivalent solution in Maria DB to achieve (start with .... connect by) and (start with ...connect by prior) recursive queries.

Below is the Procedure I want to run in Maria DB.
