Oracle Database create automatic partition by range (long)

问题

I need a lot of partition table from one of my col table and dataType is long so I don't think can do it with hardcode in Sql syntax , now my question is what can i do for partition tables with range of long and automatic keyword in oracle database 19c?

Edit : I have Timestamp formated in long and I don't want to change it date type timestamp so I need every month split to separate partition I will convert all timestamp to long and store in database (because i need to reformat my timestamp to other format like gregorian or jalali and store it long make my job easier)
