To execute a PostgreSQL stored procedure from an Azure Databricks notebook, you need to follow these steps:
- Required Libraries:
- You need to install the psycopg2 library, which is a PostgreSQL adapter for Python. This can be done using the %pip install psycopg2 command in your Databricks notebook.
- Connecting to Azure Database for PostgreSQL using ODBC:
- You can use the psycopg2 library to establish a connection to your Azure Database for PostgreSQL. Here is an example of how to set up the connection:
import psycopg2
conn = psycopg2.connect(
host="your_postgresql_host",
database="your_database_name",
user="your_username",
password="your_password"
)
Executing the PostgreSQL Stored Procedure:
- Once the connection is established, you can execute the stored procedure using a cursor object. Here is an example:
cur = conn.cursor()
cur.execute("CALL your_stored_procedure_name()")
conn.commit()
cur.close()
conn.close()
Make sure to replace "your_postgresql_host", "your_database_name", "your_username", "your_password", and "your_stored_procedure_name" with your actual PostgreSQL host, database name, username, password, and stored procedure name respectively.
