Postscript
View of the tool:
I wrote only a few examples in each example because I wanted you to extrapolate the other columns through the one or two examples. If I were to complete each injection, I would have to use tools or write code to automate it, knowing the principles. Why not take the tool directly, presumably most people start with the use of other people's tools, in fact, this habit has eroded your thinking and learning style, so in order to change, in order not to let others always say you are script kids, complete the above principle understanding is necessary.
My opinion on the whole work:
I did not write tool injection and code automation (because only some of the levels did these two jobs and were not ashamed to write) so it felt like the job was incomplete. But from the principle of SQL injection learning, the individual thinks the completion is already 95%, we basically will see in the background all the injection methods are written (Daniel do not face, I now go out is scary enough.) If there is a kinky trick, contact me and I'll add it right away! ), so do not generalize, or hope that everyone, benevolent see.
The whole work took one months, the one months did spend a lot of time, hoping to provide Yimeimei with a good learning material.
Perspectives on the Future:
Here I would like to talk about relational databases and non-relational databases.
In our example above, we use Mysql,mssql and Oracle syntax to be somewhat different, but the rationale is consistent, but it is also important to note that a certain type of database has its own specific stuff, such as the xp_cmdshell of MSSQL. But in the end, the same is true, and the demand they achieve is the same.
And now the more hot NoSQL (non-relational database), such as the advent of MONGO. Many people think that what we are learning is going to be out of date, but from the present MONGO injection process, in fact, and our relational database thinking is consistent, when you understand and then to develop nosql skills, I believe you can do more with less.
Follow-up development work on the experiment:
Although the current author has written a lot of levels, but some things are not involved. At the same time the author's project should have been stopped for a long time. If there are ideas and energies, we will fill a lot of experiments on injection. Have a common idea can add my friends together we will complete this meaningful work and create a good learning platform for Yimeimei.
