Write null to SQL Server from Access with ADO

I'm trying to write Null to a column in a SQL Server table that is set to take nulls.

I'm using ADO to do this in conjunction with stored procedure parameters.

I've tried setting the parameter value to VBNull and DBNull but VBNull loads 1 to the table and DBNull loads 0.

Is there a way for me to load nulls with ADO?

Thanks.

Hi Lee_JD

If you want to pass a null value simply don't set the parameter value at all - leave it out - or you could also set it to Empty.

Hope that helps!

I need to overwrite the value in the database with Null so not setting a value is not an option.  Also setting the value to Nothing doesn't work either.

What are you writing this in? Are you using .net, c#, vb, ASP, vb6, VBA?

It's okay.  I sorted it with

If value 0 then parameter.value = null else parameter.value = type.value
