Null Value Problem

Hello Friend,

I have connected a form using ADODC to Oracle...Every thing is fine but while modification if i put a null value & say UpdateBatch it Updates properly but then if i try to update the same recordset after passing the Null value replacing with some othervalue... it gives a Error --> The row is is last read so it cant be updated..

Pls if u can give a solution to this problem i'll be greatful -- Rohan
