Course Introduction：In MySQL or MariaDB, you need to run the FLUSHPRIVILEGES command after manually modifying the permission table. 1. When you directly execute INSERT, UPDATE or DELETE operations on permission tables such as mysql.user, mysql.db, etc., you must run this command to make the changes effective immediately; 2. When using standard permission management commands such as GRANT, REVOKE or CREATEUSER, you do not need to execute FLUSHPRIVILEGES, because these commands will automatically reload permissions; 3. After modifying the permission table through scripts or external tools, the command should be manually executed, otherwise the changes will not take effect; 4. It is not recommended to directly edit the system permission table, and it is recommended to use standard SQL missions.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
