First of all, correct, the database is called mysql is completely ok, if you talk about the database language, it can only be called sql, mysql, oracle, sqlselver and so on are all following sql rules, where you want to speed is not reached, if you want to ask for speed in development, then your bug maintenance time is enough for you to bear, so if you don't understand the database in the early stage, it is recommended that you still work steadily. If you have to use it in a hurry, I can only give you this advice.

First of all, MySQL is not a database language, the database language is SQL, and generally follows the SQL 92 standard. The easiest way to learn any language is to do it. If you want to learn more deeply, you can use MysqlClient to link in and operate directly without a graphical interface.

Start by creating, modifying, and deleting a table. Then start the normal select, insert, update, and delete to start the practice, remember the syntax, and then when you are familiar with it, start the inner join, left join, etc. When you are familiar with the above, you can go to some ** question banks to brush up on the questions, generally there will be test data for you, and then give you a question, and finally you can complete the question requirements by writing SQL statements.

More problems are exposed on **.
