This is the ninth video
This is the ninth video of Database programming with Python video tutorial series. In this video we will see how to connect to the Oracle database using the cx_oracle package and execute oracle procedures using the callproc method, we will see how we can pass parameters to the procedure from python script/
callproc(proc_name, parameters)
Steps performed:
================
Create Connection
Create Cursor
execute the procedure with callproc
close the cursor
close the connection
The cx_Oracle is a Python extension module that enables access to Oracle Database. It conforms to the Python database API 2.0 specification with a considerable number of additions and a couple of exclusions.
cx_Oracle 7 has been tested with Python version 2.7, and with versions 3.5 through 3.8. You can use cx_Oracle with Oracle 11.2, 12, 18 and 19 client libraries. Oracle's standard client-server version interoperability allows connection to both older and newer databases. For example, Oracle 19c client libraries can connect to Oracle Database 11.2.
