What is SQL injection? What I understand as SQL injection is that some people can input malicious parameters to let the background execute this SQL, and then achieve the purpose of obtaining data or destroying the database! To give a simple query example, the background sql is spliced: select * from Test where name='+parameter transfer+'; the front page requires entering name, then the hacker can enter: ';DROP TABLE Test;-- Don't underestimate this paragraph SQL code: select * from Test where name=' ';DROP TABLE Test;--'; is correct and executable in SQL, but after execution, the entire Test table is deleted and the website crashes! The best solution The best solution is not to write splicing SQL, but to use parameterized SQL, which is recommended for new projects. There is no introduction here. Interested friends can search for it by themselves. The method introduced in this article is suitable for old projects, that is, there are no programs developed using parameterized SQL.
