You might try looking in Access Help for the 'nz' function (but I can never find anything in Access help...)

In any case, the 'nz' function returns the value of its first parameter if that first parameter is not null; if the first parameter is null, then it returns the value of the second parameter.

It is similar to the COALESCE function in SQL (which Access doesn't support), but COALESCE is a bit more powerful. COALESCE returns the first non null value in its argument list, and it can have many arguments, whereas 'nz' is limited to only two values.

Hi. It's my first post and my english isn't good (I'm from Italy). So, I have a problem with ole object. My database is sql and for my query I use a odbc access in msaccess. In the database in a field there is a string (comment) that is registred as an image. If I use a sql query with the cast function the ole is transformed in a string. In msacces I'm trying the function posted. The Nz function produces a field with japanese/chinese characters. I don't understand how configure the parameter. Please, help me!!!!

This works and the result is a string:
select cast(CAST(ZusInfo as varbinary) as varchar), * from CdnFzgVerkauf

How can I have the same result in vba?

Thank you.
