Brett Bergquist commented on DERBY-5370:
----------------------------------------

I would add a test case but I am just learning my way around the code now.  It may be a bit
before I can figure out what I need to do but I can give it a shot.  It will be useful to
learn a bit more about the testing framework.

> 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.
