  1. Connecting to a MySQL Database in Python – show you how to use the connect function and MySQLConnection object to create a connection to a MySQL database. Querying Data from a Table in Python – show you how to query data in a MySQL database from Python by using Python/Connector API such as fetchone, fetchmany, and fetchall.
  2. Writing data from MySQL database table into pandas dataframe: Import the required Python modules including pandas, pymysql and sqlalchemy. Obtain an SQLAlchemy engine object to connect to the MySQL database server by providing required credentials. Using the engine object, connect to the MySQL server by calling the connect method.

Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java and XML. Best way to connect to MySQL from python is to Use MySQL Connector/Python because it is official Oracle driver for MySQL for working with Python and it works with both Python 3 and Python 2. Follow the steps mentioned below to connect MySQL.

Azure Database for MySQL - Flexible Server is currently in public preview.

In this quickstart, you connect to an Azure Database for MySQL Flexible Server by using Python. You then use SQL statements to query, insert, update, and delete data in the database from Mac, Ubuntu Linux, and Windows platforms.

This article assumes that you're familiar with developing using Python, but you're new to working with Azure Database for MySQL Flexible Server.

Prerequisites

  • An Azure account with an active subscription. Create an account for free.
  • An Azure Database for MySQL Flexible Server. To create flexible server, refer to Create an Azure Database for MySQL Flexible Server using Azure portal or Create an Azure Database for MySQL Flexible Server using Azure CLI.

Preparing your client workstation

  • If you created your flexible server with Private access (VNet Integration), you will need to connect to your server from a resource within the same VNet as your server. You can create a virtual machine and add it to the VNet created with your flexible server. Refer to Create and manage Azure Database for MySQL Flexible Server virtual network using Azure CLI.
  • If you created your flexible server with Public access (allowed IP addresses), you can add your local IP address to the list of firewall rules on your server. Refer to Create and manage Azure Database for MySQL Flexible Server firewall rules using the Azure CLI.

Install Python and the MySQL connector

Install Python and the MySQL connector for Python on your computer by using the following steps:

Mysql python connector

Note

This quickstart uses a raw SQL query approach to connect to MySQL. If you're using a web framework, use the recommended connector for the framework, for example, mysqlclient for Django.

  1. Download and install Python 3.7 or above for your OS. Make sure to add Python to your PATH, because the MySQL connector requires that.

  2. Open a command prompt or bash shell, and check your Python version by running python -V with the uppercase V switch.

  3. The pip package installer is included in the latest versions of Python. Update pip to the latest version by running pip install -U pip.

    If pip isn't installed, you can download and install it with get-pip.py. For more information, see Installation.

  4. Use pip to install the MySQL connector for Python and its dependencies:

    You can also install the Python connector for MySQL from mysql.com. For more information about the MySQL Connector for Python, see the MySQL Connector/Python Developer Guide.

Get connection information

Get the connection information you need to connect to Azure Database for MySQL Flexible Server from the Azure portal. You need the server name, database name, and sign in credentials.

  1. Sign in to the Azure portal.

  2. In the portal search bar, search for and select the Azure Database for MySQL Flexible Server you created, such as mydemoserver.

  3. From the server's Overview page, make a note of the Server name and Server admin login name. If you forget your password, you can also reset the password from this page.

Code samples

Run below mentioned Python code samples

For each code example in this article:

  1. Create a new file in a text editor.

  2. Add the code example to the file. In the code, replace the <mydemoserver>, <myadmin>, <mypassword>, and <mydatabase> placeholders with the values for your MySQL server and database.

  3. Save the file in a project folder with a .py extension, such as C:pythonmysqlcreatetable.py or /home/username/pythonmysql/createtable.py.

  4. To run the code, open a command prompt or bash shell and change directory into your project folder, for example cd pythonmysql. Type the python command followed by the file name, for example python createtable.py, and press Enter.

    Note

    On Windows, if python.exe is not found, you may need to add the Python path into your PATH environment variable, or provide the full path to python.exe, for example C:python27python.exe createtable.py.

Python Mysql

Create a table and insert data

Use the following code to connect to the server and database, create a table, and load data by using an INSERT SQL statement.

Python Mysql Connect

The code imports the mysql.connector library, and uses the connect() function to connect to flexible server using the arguments in the config collection. The code uses a cursor on the connection, and the cursor.execute() method executes the SQL query against the MySQL database.

Read data

Use the following code to connect and read the data by using a SELECT SQL statement.

The code imports the mysql.connector library, and uses the connect() function to connect to flexible server using the arguments in the config collection. The code uses a cursor on the connection, and the cursor.execute() method executes the SQL query against the MySQL database.

The code reads the data rows using the fetchall() method, keeps the result set in a collection row, and uses a for iterator to loop over the rows.

Update data

Use the following code to connect and update the data by using an UPDATE SQL statement.

The code imports the mysql.connector library, and uses the connect() function to connect to flexible server using the arguments in the config collection. The code uses a cursor on the connection, and the cursor.execute() method executes the SQL query against the MySQL database.

Delete data

Use the following code to connect and remove data by using a DELETE SQL statement.

The code imports the mysql.connector library, and uses the connect() function to connect to flexible server using the arguments in the config collection. The code uses a cursor on the connection, and the cursor.execute() method executes the SQL query against the MySQL database.
