Verify the compatibility of a Python project with MySQL version 8
To Nha Notes | Dec. 15, 2023, 6:37 p.m.
Follow these procedures to verify if the Python application code is compatible with MySQL version 8
- Search for a keyword to find all Python file paths containing SQL text.
- Iterate through each SQL text found above and ask ChatGPT if it is compatible with MySQL version 8.
# %% Finding all file paths which contain the keyword "from MySQLdb import Connection" in the project.

Sample result
Here are a few ways to check if your SQL code is compatible with MySQL version 8
- Run the SQL code using MySQL version 8 and check for any syntax or compatibility errors. This is the most direct way to test for issues.
- Check for any deprecated or removed SQL features in MySQL 8 and verify your code does not use those. The MySQL documentation lists features that were deprecated or removed between versions.
- Run the "mysql_upgrade" utility included with MySQL 8 on your existing database to check for incompatibilities. This utility performs checks and converts your metadata to be compatible.
- Use MySQL Workbench or other tools to analyze your SQL code and check for compatibility issues. Some tools can detect deprecated features or syntax that may cause problems.
- Check for any data type, storage engine, or function changes between your current MySQL version and version 8. Data types, engines or functions that changed behavior could affect your code.
- If using stored procedures or functions, check the MySQL server upgrade guide section on stored routine incompatibilities. Syntax or parameters may have changed.
- Test your application code thoroughly. Even if the SQL itself is compatible, application code interacting with the database may rely on undocumented behaviors that changed.
