CRUD FLASK AND MYSQL #1 Introduction
On this occasion Mimin will provide a tutorial on how to create a website application using Python. We will start the journey to build a CRUD application using Flask and MySQL. Before getting into coding, let's first understand what Python, Flask, MySQL, and CRUD are.
What is Python?
Python is one of the most popular programming languages ??today. Known for its simple and easy to read syntax, Python is often used for various needs such as:
- Web development
- Data science
- Artificial intelligence (AI)
- Automation
- And many more
Python has a large community and thousands of libraries that make it easier for developers to complete various types of projects.
Simple Python Syntax Example:
print("Hello, World!")
More information about Python can be found in the official Python documentation: https://docs.python.org/
What is Flask?
Flask is a Python framework used to build web applications. Flask falls into the microframework category, which means it is lightweight and does not impose a particular structure on developers.
Flask advantages:
- Lightweight: Suitable for small to medium projects.
- Modular: You can add features as needed.
- Complete Documentation: Helps beginners to get started easily.
Simple Flask Code Example:
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return "Hello, Flask!"
if __name__ == "__main__":
app.run(debug=True)
You can read complete information about Flask in the official Flask documentation: https://flask.palletsprojects.com/
What is MySQL?
MySQL is a relational database management system (RDBMS) used to store and manage data.
MySQL advantages:
- Free and Open Source: Suitable for various projects.
- Stable and Fast: MySQL is able to handle millions of data quickly.
- High Compatibility: Can be used with various programming languages ??such as Python, PHP, Java, etc.
Example of a Simple MySQL Query:
CREATE DATABASE crud_example;
USE crud_example;
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100),
email VARCHAR(100)
);

What is CRUD?
CRUD is an abbreviation of:
- Create: Creates new data
- Read: Reads or displays data
- Update: Updates data
- Delete: Delete data CRUD is a basic function that is often used in developing database-based applications.
CRUD Implementation Example:
- Create: Adds new user data to the database.
- Read: Displays a list of saved users.
- Update: Edit user data such as name or email.
- Delete: Delete unneeded user data.
Why Use Flask and MySQL for CRUD?
- Flask makes backend development easy with simple syntax.
- MySQL is a reliable database for storing data.
- The combination of Flask and MySQL is suitable for building data-driven web applications.
What Will We Build in This Series?
In this series, we will create a simple web-based CRUD application with the features:
- Adding user data (Create)
- View the list of users (Read)
- Edit user data (Update)
- Delete user data (Delete)
Each step will be explained in detail with codes and explanations.
That's an introduction to Python, Flask, MySQL, and CRUD. In the next article, we will start installing the required tools and creating the project structure.
Stay tuned to this series to learn to build CRUD applications with Flask and MySQL from start to finish!

How to add the MySQL bin directory to the system PATH
Jul 01, 2025 am 01:39 AM
To add MySQL's bin directory to the system PATH, it needs to be configured according to the different operating systems. 1. Windows system: Find the bin folder in the MySQL installation directory (the default path is usually C:\ProgramFiles\MySQL\MySQLServerX.X\bin), right-click "This Computer" → "Properties" → "Advanced System Settings" → "Environment Variables", select Path in "System Variables" and edit it, add the MySQLbin path, save it and restart the command prompt and enter mysql--version verification; 2.macOS and Linux systems: Bash users edit ~/.bashrc or ~/.bash_
What are the transaction isolation levels in MySQL, and which is the default?
Jun 23, 2025 pm 03:05 PM
MySQL's default transaction isolation level is RepeatableRead, which prevents dirty reads and non-repeatable reads through MVCC and gap locks, and avoids phantom reading in most cases; other major levels include read uncommitted (ReadUncommitted), allowing dirty reads but the fastest performance, 1. Read Committed (ReadCommitted) ensures that the submitted data is read but may encounter non-repeatable reads and phantom readings, 2. RepeatableRead default level ensures that multiple reads within the transaction are consistent, 3. Serialization (Serializable) the highest level, prevents other transactions from modifying data through locks, ensuring data integrity but sacrificing performance;
Where does mysql workbench save connection information
Jun 26, 2025 am 05:23 AM
MySQLWorkbench stores connection information in the system configuration file. The specific path varies according to the operating system: 1. It is located in %APPDATA%\MySQL\Workbench\connections.xml in Windows system; 2. It is located in ~/Library/ApplicationSupport/MySQL/Workbench/connections.xml in macOS system; 3. It is usually located in ~/.mysql/workbench/connections.xml in Linux system or ~/.local/share/data/MySQL/Wor
Performing logical backups using mysqldump in MySQL
Jul 06, 2025 am 02:55 AM
mysqldump is a common tool for performing logical backups of MySQL databases. It generates SQL files containing CREATE and INSERT statements to rebuild the database. 1. It does not back up the original file, but converts the database structure and content into portable SQL commands; 2. It is suitable for small databases or selective recovery, and is not suitable for fast recovery of TB-level data; 3. Common options include --single-transaction, --databases, --all-databases, --routines, etc.; 4. Use mysql command to import during recovery, and can turn off foreign key checks to improve speed; 5. It is recommended to test backup regularly, use compression, and automatic adjustment.
Analyzing the MySQL Slow Query Log to Find Performance Bottlenecks
Jul 04, 2025 am 02:46 AM
Turn on MySQL slow query logs and analyze locationable performance issues. 1. Edit the configuration file or dynamically set slow_query_log and long_query_time; 2. The log contains key fields such as Query_time, Lock_time, Rows_examined to assist in judging efficiency bottlenecks; 3. Use mysqldumpslow or pt-query-digest tools to efficiently analyze logs; 4. Optimization suggestions include adding indexes, avoiding SELECT*, splitting complex queries, etc. For example, adding an index to user_id can significantly reduce the number of scanned rows and improve query efficiency.
Handling NULL Values in MySQL Columns and Queries
Jul 05, 2025 am 02:46 AM
When handling NULL values ??in MySQL, please note: 1. When designing the table, the key fields are set to NOTNULL, and optional fields are allowed NULL; 2. ISNULL or ISNOTNULL must be used with = or !=; 3. IFNULL or COALESCE functions can be used to replace the display default values; 4. Be cautious when using NULL values ??directly when inserting or updating, and pay attention to the data source and ORM framework processing methods. NULL represents an unknown value and does not equal any value, including itself. Therefore, be careful when querying, counting, and connecting tables to avoid missing data or logical errors. Rational use of functions and constraints can effectively reduce interference caused by NULL.
Resetting the root password for MySQL server
Jul 03, 2025 am 02:32 AM
To reset the root password of MySQL, please follow the following steps: 1. Stop the MySQL server, use sudosystemctlstopmysql or sudosystemctlstopmysqld; 2. Start MySQL in --skip-grant-tables mode, execute sudomysqld-skip-grant-tables&; 3. Log in to MySQL and execute the corresponding SQL command to modify the password according to the version, such as FLUSHPRIVILEGES;ALTERUSER'root'@'localhost'IDENTIFIEDBY'your_new
