MySQL does not presently support stored procedures.  Some sort of
support is predicted in the future, but it's not there yet.

Personally, I'd think that if the need is for something "formally
embedded," that the database system of choice should be Berkeley DB.

Consider that:
- It supports transactions;
- Supports having multiple "tables" within a database;
- It is consciously designed to allow static/dynamic linking into apps.

It doesn't have any of the "crunchy goodness" of SQL; not only does it
not support stored procedures, but it does not support doing anything
"smarter" than using binary data as keys and values.  But it's small,
runs on all the platforms GnuCash runs on, and is certainly a "zero
administration" database system.
