PL/SQL, not SQL. Whatever I knew about PL/SQL in the 90s and early 2000s I've forgotten, but I wouldn't be so certain that PL/SQL a) does not have precise enough timing primitives, and b) does not get JITed down into machine code nowadays. It is a fully fledged, turing complete programming language with loops, arrays etc.
