I don't really consider JS or SQL to be true programming languages in the truest sense... JS is a scripting language, and SQL is a query language although you can write pretty complex stuff in stored procedures and so on. I used both in conjunction with my applications that were mainly written in C#.

SQL SERVER and ORACLE allow programming like features ( e.g. Stored Procedures ).
