David,

If dateUpdated its a date column, you should really compare against either a
NULL value or a date value.  
You seem to be comparing against a string value.

The syntax of NULL/Date value is dependant upon your database engine.

Trying to do a simple select query that
filters out records against a date column.
I want all records with an empty value in
the date column. 

Here's my query...

<cfquery name="getData" datasource="cfDS" dbtype="ODBC">
SELECT     *
FROM     tblCustomers
WHERE     dateUpdated <> ''
</cfquery>

...which blows up with this error;
===================================
ODBC Error Code = 22005 (Error in assignment)
Data type mismatch in criteria expression.
===================================

I'm assuming it's choking on the quotes. 
So what's the correct syntax?
