APPLIES TO: Azure Database for PostgreSQL - Flexible Server

This quickstart demonstrates how to connect to an Azure Database for PostgreSQL Flexible Server using Azure CLI with az postgres flexible-server connect and execute single query or sql file with az postgres flexible-server execute command. This command allows you test connectivity to your database server and run queries. You can also run multiple queries using the interactive mode.

Prerequisites

  • An Azure account. If you don't have one, get a free trial .
  • Install Azure CLI latest version (2.20.0 or above)
  • Log in using Azure CLI with az login command
  • Turn on parameter persistence with az config param-persist on . Parameter persistence will help you use local context without having to repeat numerous arguments like resource group or location.
  • Create a PostgreSQL Flexible Server

    The first thing we'll create is a managed PostgreSQL server. In Azure Cloud Shell , run the following script and make a note of the server name , username and password generated from this command.

    az postgres flexible-server create --public-access <your-ip-address>
    

    You can provide more arguments for this command to customize it. See all arguments for az postgres flexible-server create.

    View all the arguments

    You can view all the arguments for this command with --help argument.

    az postgres flexible-server connect --help
    

    Test database server connection

    You can test and validate the connection to the database from your development environment using the command.

    az postgres flexible-server connect -n <servername> -u <username> -p "<password>" -d <databasename>
    

    Example:

    az postgres flexible-server connect -n postgresdemoserver -u dbuser -p "dbpassword" -d postgres
    

    You'll see the output if the connection was successful.

    Command group 'postgres flexible-server' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
    Successfully connected to postgresdemoserver.
    Local context is turned on. Its information is saved in working directory C:\mydir. You can run `az local-context off` to turn it off.
    Your preference of  are now saved to local context. To learn more, type in `az local-context --help`
    

    If the connection failed, try these solutions:

  • Check if port 5432 is open on your client machine.
  • if your server administrator user name and password are correct
  • if you have configured firewall rule for your client machine
  • if you've configured your server with private access in virtual networking, make sure your client machine is in the same virtual network.
  • Run multiple queries using interactive mode

    You can run multiple queries using the interactive mode. To enable interactive mode, run the following command

    az postgres flexible-server connect -n <servername> -u <username> -p "<password>" -d <databasename>
    

    Example:

    az postgres flexible-server connect -n postgresdemoserver -u dbuser -p "dbpassword" -d flexibleserverdb --interactive
    

    You'll see the psql shell experience as shown below:

    Run SQL File

    You can execute a sql file with the command using --file-path argument, -f.

    az postgres flexible-server execute -n <server-name> -u <username> -p "<password>" -d <database-name> --file-path "<file-path>"
    

    Example:

    az postgres flexible-server execute -n postgresdemoserver -u dbuser -p "dbpassword" -d flexibleserverdb -f "./test.sql"
    

    You'll see an output as shown below:

    Command group 'postgres flexible-server' is in preview and under development. Reference and support levels: https://aka.ms/CLI_refstatus
    Running sql file '.\test.sql'...
    Successfully executed the file.
    Closed the connection to postgresdemoserver.
