Some link to learn SQL

Well I have little to no time to write lately, but I still want to post something so here it goes a quick set of links for learning SQL (free of course). The relationship between SQL and data science is obvious, almost all companies have a relational database to store and extract data as part of their day-to-day operation, so is a must have. So here is the list of link to learn SQL
