Many people tend to fall into a misunderstanding when using SQL, that is, they are too concerned about whether the obtained results are correct, while ignoring the possible performance differences between different implementation methods, this performance difference is particularly evident in large or complex database environments (such as online transaction processing OLTP or decision support system DSS. In my work practice, I found that poor
