I'm using the following code to trap empty dates coming into the stored procedrue from VFP call. Before I send the parameters in SQLexec(), I change the empty date from {//} to ''blank. I test about 10 dates before issuing the UPDATE. Relying on the default 1900-01-01 seems scary to me. Is there a better way?

if @ORDDATE  = '1900-01-01 00:00:00.000'
   begin
      set @ORDDATE = null
end

Thank You for your input!
