All records from the “sometable” table should be displayed below.Python Dictionaries Access Items Change Items Add Items Remove Items Loop Dictionaries Copy Dictionaries Nested Dictionaries Dictionary Methods Dictionary Exercise Python If.Else Python While Loops Python For Loops Python Functions Python Lambda Python Arrays Python Classes/Objects Python Inheritance Python Iterators Python Scope Python Modules Python Dates Python Math Python JSON Python RegEx Python PIP Python Try. for row in cursor:Ĭomplete ‘testdb.py’ Code:: import nnectorĬursor.execute("SELECT * FROM migrations")Ĭlick the Run button to see the results in our terminal window. Use a for statement to print the result of each row found. cursor = conn.cursor()Ĭursor.execute("SELECT * FROM sometable") Assign the cursor and pass a simple SELECT statement to it for execution. The connector has a cursor method that we can pass a SQL statement to and see the query results. We then create a new object using the connector and set its parameters in one line. This brings in the driver we just installed to the environment. Open the “testdb.py” file and add the following code as we explain each line. The MySQL connector is now available inside this project. Specifically we need the MySQL drivers in order to (db tales com) connect to the MySQL Database. Now that we are working inside our environment (.venv), we can install module that will be used by this project. To choose a different interepreter you can click this bar and Select a different one. The bottom left bar should now displays the correct Python version that was used to create the environment. Linux :: Browse to the “dbconnect/.venv/bin/” folder.Choose “Enter Interpreter Path” and “Find”.Type “Python Select Interpreter” and Select it.Since you may have multiple versions of Python we need to define which one to use and now that we have a virtual environment we will use that one. The interpreter uses the Python version you have installed on your system already. (.venv) C:\path\dbconnect VSCode Command Palette and Python Interpreter The command prompt should now have the environment in parenthesis before the drive letter. Activate the new environment so we can install the modules here (Linux example): source. This folder is where we will reference our Interpreter so everything is contained inside our “DBconnect” project folder. Use the following command to create a (Hidden in Linux) virtual environment folder called “.venv” python -m venv.Open the terminal window by clicking the View -> Terminal menu item.You could use only 1 environment or your system default but this is not portable or suggested. The installed drivers and modules will only be available to this project so it does not gum up the works for future projects. Create a Virtual Environment (.venv)Ī best practice is to use a virtual environment to create and manage your application requirements. py extension and ask for the Interpreter you want to use which is in a following step. But we prefer to use the MySQL Connector because of the following advantages: 1. And all of them follow the rules defined in the Python Database API Specification v2.0 (PEP 249). Note: If you use the File -> New File option it will recognize the. OurSQL All the above modules have almost the same syntax and methods to handle the databases. Choose the folder you just created and it should appear in the Explorer on the top right with no files in it.Ĭreate a new file called “testdb.py” by clicking the New File icon. Start VS Code and Open a Folder using the File -> Open folder menu item. Create this folder where you normally place your project files, this folder should be empty initially. In this example I am using a folder called “DBConnect”. We will be working inside a single project folder to create the environment and Python file. For this example we are install the “Python” extension by Microsoft which includes functions like IntelliSense, code formatting, Debugging and more.Ĭlick the “ Extensions” icon and install:īe sure to experiment with other VS Code extensions, they can save time and improve your coding experience. Part of Visual Studio Code features is that it has many extension available, including extensions for Python. The result should look like “Python 3.9.x” VSCode Python Extensions On a command line you should be able to run this to find the Python version: python -V This example uses Python 3.9 so this needs to be installed and setup in your default path. We’re going to work inside VS Code using the terminal to execute commands. Python 3.9.x installed Visual Studio Code and Python 3.9.Instance of Mysql installed with a login.The instructions should be similar on Windows, Mac and Linux but will not be exactly the same. We will also setup a Python environment and install the MySQL Connector needed to connect to MySQL and MariaDB. In this example we will be connecting to a MySQL database using the Visual Studio Code IDE.
