8. Operation summary
When I learned how to build a MYSQL data table this time, because I have not been exposed to it before and I am unfamiliar with the code, many errors have occurred in the process, but in the continuous attempt to understand and use some statements are more familiar Too. When writing code, it is necessary to write some semicolons and uppercase and lowercase norms, otherwise it will be rewritten because of a symbol, and there are words in some sentences to be remembered, otherwise it will be changed again because of a letter.
