The SQL language is not flexible enough to allow preparation of every possible query, so the problem is fundamentally not solved. To take a simple example: query parameters are not supported in DDL or DCL statements, and in DML queries the usage of parameters is limited to values only: even such a simple thing as an ORDER BY clause cannot be controlled by parameter insertion. "We have solutions for the most common occurrences" is not the same as "the problem is solved".
