when I used 'MyQuery.Params[x].Clear' for inserting some empty dates in a column database i have an erro message indicate to me that the parameter isn't filled

suprisingly if the first date isn't empty the others empty dates goes well into the table

Do I use the good syntax for doing this action ?

Thank you for your time !

We cannot reproduce your problem. Possibly your did not specify 'MyQuery.Params[x].DataType for this parameter. It is required value in Borland dbExpress.

you was right thank you very much !
