It's intentional not to have functions to set the value, since right
now, it's got no sense to do this in the client applications, since you
can't directly update an open recordset. As soon as we find a way to do
this in all the providers, all these functions will be added.

Because the last _u is a union which contains variables for all possible
data types. And what these macros do is to access the correct variable
for the given data type.
