To view tables on a PostgreSQL database hosted on Heroku, you can use either the Heroku CLI or a database client. Here’s how to do it with both methods:
Method 1: Using Heroku CLI and `psql`
- Install the Heroku CLI (if not already installed) by following the instructions on [Heroku's website](https://devcenter.heroku.com/articles/heroku-cli).
- Log in to Heroku:
heroku login
- Access the PostgreSQL Database:
Use the following command to connect to your database:
heroku pg:psql -a <your-app-name>
Replace <your-app-name>
with the name of your Heroku application.
- List Tables:
Once connected to the database, you can list all tables with:
\dt
This command will display all the tables in the current schema.
- Exit psql:
When you're done, exit the psql interface by typing:
\q
Method 2: Using a Database Client (e.g., pgAdmin, DataGrip)
- Retrieve Database Credentials:
Run the following command to get your database URL:
heroku config:get DATABASE_URL -a <your-app-name>
This will display a URL in the format: postgres://<user>:<password>@<host>:<port>/<database>
- Connect with a Client:
Open your database client, such as [pgAdmin](https://www.pgadmin.org/) or DataGrip, and enter the details from the DATABASE_URL
:
- Host: Found in the URL after
@
- Database: Found after the last
/
- User and Password: Found between
//
and@
- Port: Default is 5432 (or whatever is in the URL)
- List Tables:
After connecting, you can explore the database tables in the client’s interface. Most clients allow you to view tables directly and run SQL queries to list tables with:
SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';
Using either method will allow you to view and interact with your PostgreSQL tables on Heroku.
