使用sql update 功能,运行时系统无任何错误提示,但是数据库表单内容却没有修改。

请教高手。


源代码:
with TADOQ1 do
begin
close;
SQL.Clear;
SQL.Add('update [Tname] set [Fname1]=:Fname1');
SQL.Add('where [Fname2]=:Fname2');
Parameters.Items[0].Value:=QuotedStr(edit1.Text);
Parameters.Items[1].Value:=QuotedStr(edit2.Text);
prepared:= false;
prepared:= true;
execSQL;
end;
