Good morning.

I need to set a DateTime field which has already a valid DateTime value
to Null and have no idea how to do this.

Query.Params[10].AsDateTime := Null; <--------------
compiler error
Query.ExecQuery;

With IBEasy 1.5.3 the following does work:

update VI_Master set Date_Paid = Null where record_no = 12

I will greatly appreciate any hint how to go about it.
