How to connect to a Serverless SQL Database
This page shows you how to set up the connection to a Serverless SQL Database using the Scaleway console.
Overview
To connect to a Serverless SQL Database, you can either use a connection string, or connection parameters.
-
A connection string provides the necessary information and parameters to establish a connection between an IAM user or application, and the database. The string is written as follows:
postgres://[user-or-application-id]:[api-secret-key]@[database-hostname]:5432/[database-name]?sslmode=require
-
Connection parameters provide the necessary information and parameters to connect an IAM user or application to a database. The parameters are expressed in the
KEY="value"
format, as follows:PGUSER="user-or-application-id" PGPASSWORD="api-secret-key" PGHOST="database-hostname" PGPORT="5432" PGDATABASE="database-name"
Before you start
To complete the actions presented below, you must have:
- A Scaleway account logged into the console
- Owner status or IAM permissions allowing you to perform actions in the intended Organization
- Created a Serverless SQL Database
How to set up credentials
-
From the Overview tab of your database, click the Set up credentials button. The setup wizard displays.
-
Select the principal to connect to the database, who can be either:
- Yourself, as an IAM user, or
- An IAM application you previously created in the IAM section of the console.
-
Set up the connection string or connection parameters.
If you already have an API secret key, replace the
[INSERT_SECRET_KEY_HERE]
placeholder with your secret key as shown below.- Connection string:
postgresql://example-user-4052-8739-2017c3d9c0d9:example-secret-key-3fd8f53210ec@example-host-4d89-8e7d-g56vb754.pg.sdb.fr-par.scw.cloud:5432/serverless-sqldb-example-db?sslmode=require
- Connection parameters:
PGUSER="example-user-4052-8739-2017c3d9c0d9" PGPASSWORD="example-secret-key-3fd8f53210ec" PGHOST="example-host-4d89-8e7d-g56vb754.pg.sdb.fr-par.scw.cloud" PGPORT="5432" PGDATABASE="serverless-sqldb-example-db"
If you do not have an API key, click Generate new secret key.
A new secret key is created, and inserted directly into the connection string and parameters.
The newly created API key can be found in the API keys section of the Scaleway Console.
- Connection string:
-
Copy your connection string or parameters and store them securely, as they will only be shown once.
How to connect to a database as a user
-
Run the following command in a terminal (including the
"
characters):psql "[YOUR_CONNECTION_STRING]"
An output similar to the following response displays:
psql (15.3, server 14.8 (Debian 14.8-1pgsg120+1)) SSL connection (protocol: TLSv1.3, cipher: TLS_AES_128_GCM_SHA256, compression: off) Type "help" for help.
-
Run the following command to see the version of your Serverless SQL Database:
SELECT version();
An output similar to the following displays:
PostgreSQL 14.8 (Debian 14.8-1.pgdg120+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14) 12.2.0, 64-bit
