Hi,

I read at MysQl.com about Explain SELECT, it says at then end of a =
paragraph to optimize your query, using filesort or temporary, but I =
went to MySQL search engine no luck on finding them, can someone explain =
me both type.
**What i'm doing, since I'm using mysql for a program***=20
**I execute a query=20
**when i get the query , I'm putting everything in a hash dbm
**Then i read the line i want to, I'm doing so because it is easy to =
overwritte info on the dbm which i really want to.

Thank You
Anthony
