RE: How to READ/WRITE directly on MyISAM data files ?

So my first question should be : Is there a way to hide a field ??

SELECT only the information you want. Let's say I have

RowID 
Name
Address
City

And I only want Name Address  and City

SELECT Name, Address, City FROM table WHERE RowID = 'foo'
UPDATE table SET Name = 'foo' WHERE RowID = '12'

etcetera

A good book on SQL basics will get you a long way on things like this.
