Re: any faster select count(*)

Dear,

Thank you for your replies.

First I haven't try them because the database has no data at this time.

Thank you irek kordirko, I know the results are different. I only learned SELECT COUNT(*) from the book. I think they are the same in speed because they always run through all the matched row. When someone told me there is a difference between them, I have to clarify.

Thank you.

Best Regards,
Antony
