The thing about SQL is that that is the language your database server understands. It is possible but extremely unlikely for DB servers to understand more than one language. However, if you found one that did understand more than one language, it is a toss of a coin whether that second languyage would be Pascal or Basic or FORTRAN or Perl or ..... But, in fact, none of those languages are suitable for dedscribing set operations on data base tables.

If a database server DID understand Perl how would you specify that it should find you all single employees under age 25 who have more than 5 hours overtime this week?
