Lets upon that:

"tn" is the transaction to ibDSQL
var ib_col1,ib_col2, ... ib_coln:Tib_Column;

tn.BeginBusy(False);
ib_col1:= ibDSQL.ParamByName('col1');
ib_col2:= ibDSQL.ParamByName('col2');
....
....
ib_coln:= ibDSQL.ParamByName('coln');

ibDSQL.Prepare;
while not MemTable.EOF do
begin
ib_col1.AsString := MemTableCol1.AsString;
...
ib_col10.AsFloat:= MemTableCol1.AsFloat;
{Execute}
ibDSQL.Execute;
MemTable.Next;
end;
tn.EndBusy;
try
tn.Commit;
except
RollBack;
end;
