Ozi  when you create a new datetime object as in datetime foo   new datetime    foo is constructed with the time datetime minvalue   in building a parameterized query  you could check to see if the values entered are equal to datetime minvalue    -Just a side thought  seems you have things working

I was having the same issue this morning  It appears that for a DATE or DATETIME field  an empty value cannot be inserted  I got around this by first checking for an empty value   mydate       and if it was empty setting mydate    NULL  before insert   The DATE and DATETIME fields don t behave in the same way as VARCHAR fields
