PyQt5 Tutorial – Simple Login with MySQL in PyQt5

In this PyQt5 Tutorial we want to learn creating of Simple Login with MySQL in PyQt5, before this we have learned how you can work with mysql database and pyqt5, we have learned about mysql database connection, inserting data and selecting data from mysql database in pyqt5. you can check the articles in the below links.

As i have already said we want to use MySQL Connector, you need to install this library.

Make sure that you have already installed Wamp Server, and you have the database and table in your Wamp Server, you need to read the previous articles that i have already added the links at the top.

Open your Qt Designer, you can just write pyqt5designer in your terminal, after opening the Qt Designer you need to create Widget window. now we add widgets in Qt Designer.

• Add QHBoxLayout in QHBoxLayout add a QLabel and QLinEdit
• Add another QHBoxLayout, you need to also add a QLabel and QLineEdit in this layout
• Add a QVBoxLayout, in this layout add a QLabel with a QPushButton
• At the end click on the main window and select layout vertically for all widgets
• Also you need to add a vertical spacer between the lineedits and button.

This is the design that we want.

After completing the design you need to save your design, the extension will be .ui file. now it is time to convert our .ui file in to .py file. there are two ways that you can do, first way is loading the ui file, the second way is converting the .ui file to .py file, we want to use the second way. for converting of the ui file to python file we need to use pyuic5 module, this module is located in the Scripts folder of your python installation, you need to copy your ui file in the Scripts folder of your Python installation. after that open the terminal in the Scripts folder, and run this command.

In this Python PyQt5 lesson we want to learn about Python PyQt5 MySQL Database Login App, before this we have learned how you can work with mysql database and pyqt5, we have talked about mysql database connection, inserting data and retrieving data from mysql database in Python PyQt5.

Now open your Qt Designer, you can just write pyqt5designer in your terminal, after opening the Qt Designer you need to create Widget window. now we add widgets in Qt Designer.

• Add an HBoxLayout in QHBoxLayout add a label and lineedit
• Add another HBoxLayout, you need to also add a label and lineedit in this layout
• Add a VBoxLayout, in this layout add a QLabel with a QPushButton
• At the end click on the main window and select layout vertically for all widgets
• Also you need to add a vertical spacer between the lineedits and button.

After completing the design you need to save the .ui file, iam going to name it login.ui, now copy the file and paste it in the Scripts folder of your Python installation, because we want to convert our ui file in to python file and for converting you need to use pyuic5 module. pyuic5 module is located in the Scripts folder of your Python installation, run this command for converting in your terminal.

So this is the converted file, also we have brought some changes to this file.

So we have added one method in our file and that is for login, first we want to get the email and password from the user and after we compare that with the registered email an password of our database. in the successful login we want to open the second dialog.

Also we have connected our QPushButton clicked signal with this method.

Run the complete code give the correct email and password.

PyQt5 Tutorial – How to Create MySQL Database in PyQt5

In this PyQt5 Tutorial we want to learn How to Create MySQL Database in PyQt5, for GUI design we want to use pyqt5 and for MySQL database connection we use mysql connector, Mysql Connector is MySQL driver written in Python which does not depend on MySQL C client libraries and implements the DB API v2.0 specification (PEP-249).

Also if you are interested in Python GUI Development with different libraries, you can check the below links.

Installation

You can simply use pip for the installation.

Also you need to download and install Wamp Server, because we want to use Wamp Server as virtual server for the mysql database.

OK now it is time to design our GUI application in PyQt5 using Qt Designer, you need to open your Qt Designer by writing pyqt5designer in your terminal, after that you need to choose Widget window from the template, there are different templates but we want to use Widget template. and start designing your GUI application.

• Add QHBoxLayout and in the HBoxLayout add a QLabel and a QLineEdit
• Add another QHBoxLayout, and in the HBoxLayout add two QPushButton
• Also you need to add a QLabel and at the end make the window layout vertically
• You need to add a vertical spacer between your QLineEdit and buttons

This will be your design at the end.

After completing the design you need to save the your design, the extension will .ui file, now it is time to convert our .ui file in to .py file. there are two ways that you can do, first way is loading the ui file, the second way is converting the .ui file to .py file, we want to use the second way. for converting of the ui file to python file we need to use pyuic5 module, this module is located in the Scripts folder of your python installation, you need to copy your ui file in the Scripts folder of your Python installation. you need to open the terminal in the Scripts folder, and after that run this command.

In this PyQt6 lesson we are going to learn about PyQt6 MySQL Database Programming, we will learn that how you can create database using GUI designer, how you can insert and retrieve data and how you can create a simple login in PyQt6 with MySQL database.

First we need to install MySQL Connector, it is MySQL driver written in Python which does not depend on MySQL C client libraries and implements the DB API v2.0 specification (PEP-249).

After that you need to download and install WAMP Server, because we want to use wamp server as virtual server for mysql.

Creating MySQL Database

First we want to create our database using a GUI design, so open your Qt Designer using pyqt5designer.

• Add QLabel and QLineEdit make the layout horizontally
• Add two QPushButton make the layout horizontally
• Add QLabel below the QPushButton
• Make the main window layout vertically
• Add horizontal spacer between buttons and lineedit

Now we want to convert our UI file to Py file.

This is the converted file and we have added some codes for creating the database and database connection.

In the above code this is our method for creating the database in the WAMP Server, we can use connect() method from MySQL connection, you need to add the host, username and password as parameter, after that create the object of cursor(), also we need to get the value or database name from the QLineEdit, at the end just execute your query for creating the database.

Run the code give the database name and you have your database in WAMP server.

Using this code you can check database connection.

Click on the Database Connection button and this will be the result, if you change the database name you will get error.

Inserting Data to MySQL Database

Now we want to insert some data in to our database, first of all you need to create a table in your pyqt6 database, iam going to call it users, after that we design our GUI application for inserting data, open Qt Designer.

• Add two QLabel and two QLineEdit, make the layout horizontally
• Add QPushButton and QLabel.
• Make the main window layout vertically
• Add horizontally spacer between QLineEdit and QPushButton

Now convert your UI file to PY file.

This is our converted file.

And this is the method for inserting the data, we have connected this method with the clicked signal of the QPushButton, this is the change that we have brought to our file, first we have created our database connection code and after that we have got the value from the QLineEdits, at the end we have executed our query for inserting the data.

Run the code and insert the data this will be the result.

Check your Wamp Server and we have the data.

Retrieving Data from MySQL in QTableWidget

Now we want to retrieve data from MySQL database in to QTableWidget, open your Qt Designer.

• Add two QLabel and two QLineEdit, make the layout horizontally
• Add QTableWidget,add column row and column count
• Add QPushButton
• Make the main window layout vertically

Now convert your UI file to PY file.

This is the converted file, also we have added a new method in here for showing the data in the QTableWidget, we have connected the method with the clicked signal of QPushButton.

Run the code, give the database and table name, this will be the result.

Creating Simple Login in PyQt6 with MySQL

Now we want to create a simple login with MySQL database in PyQt6, Open your Qt Designer, you can just write pyqt5designer in your terminal, after opening the Qt Designer you need to create Widget window. now we add widgets in Qt Designer.

• Add an HBoxLayout in QHBoxLayout add a label and lineedit
• Add another HBoxLayout, you need to also add a label and lineedit in this layout
• Add a VBoxLayout, in this layout add a QLabel with a QPushButton
• At the end click on the main window and select layout vertically for all widgets
• Also you need to add a vertical spacer between the lineedits and button.
