Subject [jira] [Commented] (DERBY-5370) 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

Rick Hillegas commented on DERBY-5370:
--------------------------------------

Thanks for the patch, Brett. I think that this should cover the comparable Derby types. Since
BLOB and CLOB aren't comparable I don't think we need cases for them. If you want to add a
test case to RestrictedVTITest, that would be great. If you don't want to, I will beef up
the patch with a test. Thanks.

> 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.
