You don't tracking code, how to know the final SQL, how do you know the program is how to deal with it?
For example: the program will remove the last character, still feel strange?

Ok, I'll caught the next process,

CodePudding user response:

You this problem, the more strange,

To comment, when used in SQL injection, are in use at the end bottom, purpose is to void the latter part of the original SQL statement,

The + - +, should is ineffective, with and without
should be the same!
