# Portswigger SQLi-Lab 3
## SQL injection UNION attack, retrieving data from other tables
This lab is continuation from the previous sqli labs and in this we have to retieve the data from `users` table having column names `username` and `password` knowing that the GET paramter `category` is vulnerable to sqli , since the tables are changed we may have to know columns from "ORDERY BY" query in sqli

So we have only 2 columns in the table

Since we know the table name we can grab data from it using the column names which are also known

With this we can grab the usernames and passwords from table
