Timestamp in MySQL

Someone please help me with MySQL. I have a field in the table that contains the UNIX timestamp. Using PHP, I can format that timestamp in any way I like.

Now, I want to fetch rows for a particular date. For example, all rows having timestamp equivalent to 11th November 2007 or all rows having timestamp equivalent to 7th January 2006.

One method is to fetch all rows using MySQL query and then using PHP, filter them using If-Else and the PHP function I use to format the timestamp. I can do it easily but this method is not the right way and it may create problems later when the data grows.

What's the other way? Actually I want to filter the records through the MySQL query. It should be something like this: "select * from mytable where timestamp=____". As you know, timestamps are the seconds and for each day (e.g 11th November 2007), their values will be different for all the rows belonging to that date. In short, I want to convert timestamp to ordinary date in the MySQL query and probably using any MySQL function.

Anyone has any idea how to proceed?

Try FROM_UNIXTIME(unix_timestamp,format)

e.g. 1194873780 = 12th Nov 2007 @ 08:23am, then

FROM_UNIXTIME( 1194873780, '%d %m %Y');

would yield 12 11 2007, You can format it the way you want, for more details about date formatting check DATE_FORMAT(date,format) function in MySQL.

About UNIX timestamp:

The unix time stamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970.
