Description Jin Choi 2002-04-05 06:51:52 UTC
Unless I am missing something, it is not possible to update or insert an empty 
string or null using the sql:param tag, because it explicitly does not allow 
use with an empty value. This is a serious shortcoming! Also, the SQL standard 
differentiates between the empty string and null, although Oracle conflates the 
two, so for ANSI compliant databases, there should also be a way to set null 
parameters with the sql:param tag.

Fixed. Null parameter values set to SQL value null.
