I highly recommend this Stanford class: https://class.stanford.edu/courses/DB/SQL/SelfPaced/about It has good exercises and is quite short. There is also this online tutorial: http://sqlschool.modeanalytics.com/
I Might suggest Stanford's course that they offer for SQL stuff: https://lagunita.stanford.edu/courses/DB/SQL/SelfPaced/courseware/3d4b35a7e27b48d99f190cdcfcb40db8/fae22ef7ef60467f94b8f7b6f0220a4f/
