MySQL Driver Implementation Guide

The implementation principle of the MySQL driver is to establish a connection and perform operations with the MySQL database through communication.

Specifically, the MySQL driver establishes a connection with the MySQL server using sockets and interacts with the server through the MySQL protocol. The driver sends SQL statements to the server and receives the results back from the server.

The driver is responsible for parsing SQL statements and converting them into the protocol format required to interact with the MySQL server. This involves encoding the SQL statements into a byte stream and sending them to the server, then parsing the results returned by the server. The driver is also responsible for managing database connections, including establishing connections, closing them, and managing connection pools.

The MySQL driver also needs to handle database transaction management, data type conversion, data set processing, and exception handling. It also provides interfaces for developers to interact with the database.

In general, the implementation principle of MySQL driver is to communicate with the MySQL server, convert SQL statements into the protocol format required by the server, parse the results returned by the server, and manage database connections and other related operations.
