I created my tables this way

Thanks m8

One another question about bitmask and bitwise in DB and queries
I've multiple status for each entry on the table, such as SHOWN or HIDDEN, PREMIUM or FREE, ...
i can add one field for each status, for example 3 TINYINT(1) or BOOL fields
[SQL]
SELECT * FROM table WHERE `x`=1 AND `y`=0 AND `z`=1
[/SQL]


another method in my mind is use one TINYINT filed for all cases
INSERT and SELECT rows using AND(&) bit operand
for example
[SQL]
SELECT * FROM table WHERE `status`&5
[/SQL]
where 1 stands for x, 2 for y and 4 for z

which one is better? is there any difference in performance?
