Hi Sorin,
-----------
I would say that support for NULL is documented as: The functions that accept NULL values as parameters should propagate it to the result.
And VFP does that. The functions that do not accept NULL as parameter generate errors.
-----------
Then, for me, VFP have a support of NULL partial.
--------------
If in SQL Server all functions support NULL parameters, then all SQLServer functions should propagate NULL to the result.
--------------
Then, for me, SQL Server have a support of NULL full.
But this is only my opinion.
