To execute a PostgreSQL stored procedure from an Azure Databricks notebook, you need to follow these steps:

1. 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.
2. 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.
