In terms of SQLi, there's a lot more to It than a Union-Based attack (as per your documentation and link).

To name a few, there's Out-Of-Band (not widely used as the rest), Inferential, Error-Based, (very commonly used), Blind SQLi and Boolean-Based (or as some refer It as Content-Based). Also a few others that are not worth mentioning. I shall read the rest In detail soon.

Appreciate the guide, thank you.

Absolutley, there are alot more in SQLi. But I was making it newbie friendly as Union base is the common one.
