call materialized view in django postgres

To call a materialized view in Django with PostgreSQL, follow these steps:

  1. Import the necessary modules:
  2. Import the connection module from django.db to establish a connection with the PostgreSQL database.

  3. Import the cursor module from django.db to execute SQL queries.

  4. Establish a connection with the database:

  5. Use the connection module to establish a connection with the PostgreSQL database.

  6. You can use the connection.cursor() method to create a new cursor object.

  7. Execute the SQL query:

  8. Use the cursor object to execute the SQL query to call the materialized view.
  9. Pass the SQL query as a string to the execute() method of the cursor object.
  10. The SQL query should be in the format: SELECT * FROM <materialized_view_name>.

  11. Replace <materialized_view_name> with the actual name of the materialized view.

  12. Fetch the results (optional):

  13. If you want to retrieve the results of the SQL query, use the fetchall() or fetchone() method of the cursor object.
  14. The fetchall() method returns all the rows from the result set, while the fetchone() method returns a single row.

  15. You can store the fetched results in a variable for further processing.

  16. Close the cursor and the database connection:

  17. After executing the SQL query and fetching the results (if necessary), close the cursor and the database connection.
  18. Use the close() method of the cursor object to close the cursor.
  19. Use the connection.close() method to close the database connection.

Note: Make sure you have the necessary permissions and access rights to call the materialized view in the PostgreSQL database.
