Re: [Zope] class Missing.Missing help

I have a ZSQL method executing a simple 'select' statement against a MS SQL Server. Some of the rows/columns have missing values. On looking at the variable 'type', I get - <extension class Missing.Missing at 013130E0>

How do I test if the return value is a NULL value? e.g., as in if variable is None: do something...

If I assign this value to a variable in a dictionary, I get - {'variable':Missing.Value}

This is a bug in your Database Adapter. It should use "None" to represent an SQL "NULL" value. I do not think, there is a better work around than the one you described in your other message. Dieter
