Hi,

How does a sql query work ? how does it get compiled ? Is the from clause complied first to see if the table exists ? How does it actually retrieve data from the database ? How and in what format are the tables stored in a database ?

I am using phpmyadmin is there anyway I can peek into the files where data is stored ??
