Algorithm of "select" statement

I'm a MySQL newbie.
As I have to access MySQL database in Pocket PC, I'm developing a
evc++ program to read and retrieve data from MySQL table.
Where can I get some detail information about how "select" and "where"
statements work in the format, index and data files of MySQL database?

Thanks a tone!!!

Using "SELECT * " is a bad practice even when using a VIEW instead of a table? I have some stored procedures that are identical with the difference of one statement in the WHERE clause.
