Can somebody enlighten me as to *when* Access creates a query that has
"=null" in it?
I just tried to reproduce it, and I failed.
I type Access 97SR2 Access 2000SR1
------ ------------ --------------
=NULL Is Null =Null
IS NULL Is Null Is Null
<>NULL Is Not Null Is Not Null
IS NOT NULL Is Not Null Is Not Null
Seems to me that Access 2000 *allows* you to write =Null, but if you write
"Is Null" (correct), it will leave it alone. And <>NULL is always converted
to Is Not Null.
I don't have any Access 95 around - but it's so old that hardly anybody
should be using it anymore, right? :-)
Problem is that it's too easy to change your MS SQL Installation to work in
"the old way". Simply have the clients click in a box when they create the
ODBC datasource. The downside of backwards compatibilty is not forcing
people to fix their stuff :-)
