Margus Veanes and Pavel Grigorenko present a new exciting project: Qex. Pavel did an internship in the Research in Software Engineering team (RiSE) investigating automatic data generation methods for parameterized SQL queries. In this video, he shows the result of his 3-month work. Qex translates SQL queries to logic formulas and give to our in-house constraint solver, Z3. When Z3 finds a solution, Qex translates that solution back to SQL code that can be executed in the database. This is similar to how Pex works.
