Why not create a descendent class simply ?
Yes it is what I have used ;-)
I have one instance of variable:
TRemoteQuery has ExecSQL(A,B) as own method.
I wanted use TSQLQuery but only difference is missing ExecSQL(A,B) so I
want create helper and add this missing method.
I know that I can solve it with descendant, which I did before, but I am
still interesting if it is possible do with helper and in general if
there can be overloaded method ...
