No, it does not exist. Mnesia has no SQL interface.

We do however have a prototype of an SQL interface, which was
implemented as a master thesis work. For a small subset of SQL, the
compiler translated SQL queries into the internal form of the
Mnemosyne query compiler, and then used Mnesmosyne's backend to
evaluate the query.

There is a substantial amount of work needed, in order to implement a
fully SQL compliant interface for Mnesia. We have no such plans for
the moment.
