Looks like the usage of Lower() function in a query of query does not work
as in standard SQL.
Simple example: if you have a table containing names ( first_name
middle_name and last_name) the following query of query :

<cfquery name=�myquery� dbtype=�query�>
      select * from myfirstquery where Lower(middle_name) like �%mat�
<cfquery>

gives the following error message:

�The system has attempted to use an undefined value, which usually indicates
a programming error, either in your code or some system code.
Null Pointers are another name for undefined values. �
In case on of the rows has no value for middle_name..

This SQL statement perfectly works in Oracle or other DB.
