Sorry for my English. I'm brazilian.
Please, I use Delphi with TSQLQuery, TDataSetProvider, TClientDataSet and TDataSource.
When I open a form, I execute a SQL. It is fast. But I close the form (just the form, not the application) and reopen it, the SQL is very slow.
What is it happening??
If someone has this problem, please help me now.
Thanks.
