Hi !
I'm using a TADOQuery to insert data into a table with the Parameters from
another table.
When I execute the query, if I got a NULL field I got a EOleException that
says "Parameter object is improperly defined. Inconsistent or incomplete
information was provided"

My code's like this:
ADOQuery1->Parameters->Items[0]->Value =
ADOQuery2->FieldByName("field1")->AsString;
...

this : ADOQuery1->Parameters->Items[0]->Value = NULL;
doesn't work as well, and the paNullable option of the Attributes property
doesn't change anything.

How can I insert data with NULL value ?

Thanks
