#29759 closed Bug (fixed)

Add support for cx_Oracle 7

Reported by: Mariusz Felisiak Owned by: Mariusz Felisiak
Component: Database layer (models, ORM) Version: 2.1
Severity: Normal Keywords: Oracle
Cc: Triage Stage: Ready for checkin
Has patch: yes Needs documentation: no

Description

The Oracle back-end doesn't work with cx_Oracle=7.0.0, example exception

File "django/db/backends/oracle/operations.py", line 229, in fetch_returned_insert_id
    return int(cursor._insert_id_var.getvalue())
TypeError: int() argument must be a string, a bytes-like object or a number, not 'list'

It is caused by a following change:

14. When a DML returning statement is executed, variables bound to it will return an array when calling Variable.getvalue(). Attempts to set cx_Oracle.__future__.dml_ret_array_val are now ignored.

(see ​cx_Oracle 7 release notes).
