If nothing else happens, it will print Say something: database flavor MySQL is not supported
I found the answer on stackoverflow: The flavor 'mysql' is deprecated in pandas version 0.19.
Let's try another way:

After running, ok, you can save the index parameter to indicate whether to store the index of the DataFrame as a column. Generally speaking, it is not needed, so the value is False
Now it seems that the problem has been solved, but there is still There is a small problem.
If I have a csv file containing Chinese (my Window):
name age class
Xiao Ming 15 first grade
Xiao Zhang 18 third grade
1 2 3 4 5 6 7 8 |

After printing, the characters are garbled . It is best to specify the encoding when we read csv. My local GBK:
1 |

We can print information normally, but an error is reported again. The error is as follows:
UnicodeEncodeError: 'latin-1' codec can't encode characters in position 0-1: ordinal not in range(256)
It's still an encoding problem. The reason is that we didn't specify the encoding when we saved it to the database. I was also fooled when I was trying to solve this problem. Everything on the Internet is available. I won’t talk about the process, but look at the code:

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

In MySQL, the function of foreign keys is to establish the relationship between tables and ensure the consistency and integrity of the data. Foreign keys maintain the effectiveness of data through reference integrity checks and cascading operations. Pay attention to performance optimization and avoid common errors when using them.

The main difference between MySQL and MariaDB is performance, functionality and license: 1. MySQL is developed by Oracle, and MariaDB is its fork. 2. MariaDB may perform better in high load environments. 3.MariaDB provides more storage engines and functions. 4.MySQL adopts a dual license, and MariaDB is completely open source. The existing infrastructure, performance requirements, functional requirements and license costs should be taken into account when choosing.

MySQL and phpMyAdmin can be effectively managed through the following steps: 1. Create and delete database: Just click in phpMyAdmin to complete. 2. Manage tables: You can create tables, modify structures, and add indexes. 3. Data operation: Supports inserting, updating, deleting data and executing SQL queries. 4. Import and export data: Supports SQL, CSV, XML and other formats. 5. Optimization and monitoring: Use the OPTIMIZETABLE command to optimize tables and use query analyzers and monitoring tools to solve performance problems.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

Installing MySQL on macOS can be achieved through the following steps: 1.
