I think it will prove hard to get proficient with SQL quickly, because you need to understand the relational model. I’ve interviewed people who tried to B.S. on relational/SQL questions, it was very obvious.

Chris (C. J.) Date’s books are good, depending on your programming and data management background.

Thanks for your help! I know a little bit of SQL and I'm doing a course online on Udemy to improve my skills before the interview. I have 2 weeks to prepare.
