Try https://github.com/triska/ediprolog for a great interactive Prolog mode for Emacs. Much better that SLIME (as I remember it from briefly playing with it ten years ago): There is no notion of moving code from your edit buffer to a REPL, the code in your edit buffer is your program. Queries are also part of your program (using special comment syntax) rather than entered in a separate REPL and lost when you close that.

I think Tuareg-mode also makes the OCaml part a lot less painful. It's a bit unfair to compare Lisp used with tight Emacs integration to OCaml used seemingly without the corresponding integration.
