You don't need to change any configure options.  It seems you found a bug.  
Thanks.  

Freddy is not sure how SQLPutData() should behave when the buffer length of 
the bound parameter is zero.  

It's not clear to me what you're doing.  In SQLBindParameter(), you specify a 
parameter buffer size of zero, but in SQLPutData(), you pass it a buffer of 3 
bytes, not zero.  

I think if you change your description of the size of cbName, your code will 
work (better).  

HTH.
