--------------------------------------

Thanks for that quick response, Brett. In case you haven't stumbled across this material yet,
a good place to start is http://wiki.apache.org/db-derby/DerbyTesting . RestrictedVTITest
is a JUnit test so the material on JUnit testing is particularly relevant.

> The toSQL method of the org.apache.derby.vti.Restriction class does not output correct
constants for VARCHAR, Timestamp, Date, Time, or CHAR FOR BIT DATA types.  This method is
useful for building the WHERE clause when implementing a Restricted Table Function.  The result
of calling the toSQL method with restrictions on columns of these types does not produce valid
SQL constants.  For example with a VARCHAR column being restricted the single quote characters
are not placed round the string constant.
