Hi,
is there posibility introduce in class helper method with same name like in
base class ?
For example:
TSQLQueryHelper = class helper for TSQLQuery
public
procedure ExecSQL(const ASQL: string; const Args: array of const);
overload;
end;
procedure TSQLQueryHelper.ExecSQL(const ASQL: string; const Args: array of
const);
begin
SQL.Text := Format(ASQL, Args);
ExecSQL; // here I want call ExecSQL of TSQLQuery, but compiler complains
about wrong number of parameters
end;
When I use:
inherited ExecSQL;
it compiles (and why is there need to use "inherited", when I use overload
and there exists method ExecSQL without parameters?)
, but later I get again error "Wrong number of parameters specified for call
to "ExecSQL"",
when I want use ExecSQL('',[]) in instance of TSQLQuery
Why not create a descendent class simply ?
Michael.
