Abstract: Datalogis the language of logic programs without function symbols.It is used as a database query language.If it is possible to eliminate recursion from a Datalog program F', then t' is said to be bounded.It is shown that the problem of deciding whether a given Datalog program is bounded is undecidable, even for linear programs (i.e., programs in which each rule contains at most one occurrence of a recursive predicate).It is then shown that every semantic property of Datalog programs is undecidable if it is stable, is strongly nontrivial, and contains An earlier version of this work appeared under the same title in the Proceedings of the 2nd IEEE Symposium on Logic i~z Computer Science (Ithaca, N.Y.).
