Oracle database sequences generated by Django

[Harold A]

Hello everyone.

I have a web application built in Django == 1.11.6, when the migrations were generated in oracle the sequences are created and they can be modified and even deleted. 

When I update to django 3 and I generate the migrations again, it creates the sequences with a name similar to this (ISEQ $$ _ 76200) but it does not allow me to edit them and or delete them, it shows me the following message (ORA-32794: cannot delete a sequence generated by the system). The downside is that I have a stored procedure that drops a stream and recreates it to load with data from other tables each time it is run. 

(BEGIN / * DELETE RPT DATA ------------------------------------------- --- * / / * INITIALIZE THE SEQUENCE --------------------------------------------- - * / DELETE FROM SISREPORTS_RPT02; EXECUTE IMMEDIATE 'DROP SEQUENCE SISREPORTS_RPT02_SQ'; EXECUTE IMMEDIATE 'CREATE SEQUENCE SISREPORTS_RPT02_SQ INCREMENT BY 1 START WITH 1 MAXVALUE 9999999999999999999999999999 MINVALUE 1 CACHE 20 '; /*FINISH ----------------------------------------------- -------------------- * /) 

 My question is that if the new versions of django can do some configuration before generating them migrations and can have the option to modify the oracle sequences.
