using timestamp in where clause with mysql

i spend alot of time search how to use the timestamp in where clause with mysql finally i made, it was like i had time stamp stored in my data base i need to fetch data by year, i need some thing like

$sql = “SELECT * from tbl where timestamp = ‘2011’ “;

so i searched it alot and finally via mysql official site i found way out of it using mysql inbuilt function as below

mysql> SELECT EXTRACT(YEAR FROM ‘2009-07-02’);
-> 2009

mysql> SELECT FROM_UNIXTIME(1196440219);
-> ‘2007-11-30 10:30:19’

then i combine it like …..

$sql = “SELECT * from tbl where EXTRACT(YEAR FROM FROM_UNIXTIME(timestamp)) = ‘2011’”
