Oracle type 2016 "INTERVAL YEAR(2) TO MONTH" not supported

[adoutt]

I can do it properly with PL/SQL tool but ues cx_oracle following questions appear
cursor.execute('''select * from (select * from "ABC"."ALL_TYPE_TABLE5" order by dbms_random.random()) where rownum <= 1000''')
cx_Oracle.NotSupportedError: Oracle type 2016 not supported.

create table ALL_TYPE_TABLE5
(

Thanks for taking time to create the report. It is INTERVAL YEAR(2) TO MONTH that fails, as no doubt you know. I'll let @anthony-tuininga comment on the feasibility of support for this.

For reference, you can format code in github issues using https://help.github.com/en/github/writing-on-github/creating-and-highlighting-code-blocks

Since Python does not natively support interval year to month data, cx_Oracle would have to implement an object itself. Do you have a need for it? If you do, can you explain what you would like to see included in this new type, other than the number of years and the number of months?

From my point of view, I am willing to accept this new type to ensure that my code will not fail to read this table due to this type of error

@adoutt can you write a PL/SQL function that accepts INTERVAL YEAR TO MONTH and returns some kind of string? Then use this in your query and convert that string in Python to whatever you want.
