Yes. I'm working with the Firebird (formerly Interbase) API at the
moment, and it does exactly this. You give it an SQL query containing
'?' markers, and it parses and fully groks it, consults the database
metadata, and gives you back a structure describing the expected types
of all the parameters.

It would be utterly impossible to get it to do this with anything less
than a fully-formed syntactically and semantically correct SQL
