获取所有数据，直到当月

Question

I have a database with two columns MONTH and TEXT.

How can i display all the entries but not those that are in months that exceed current month? (eg if i have text in March, August and December and we are in August, i only want March and August texts to be displayed.)

<?php

// select all data at once

$construct ="SELECT * from table WHERE MONTH(DataIntroducere) = ???";
rest of code

?>

I want to have this because i will enter future month text and i don't want it displayed.

Answer 1

Try like

$construct ="SELECT * FROM table WHERE MONTH(DataIntroducere) <= ".date('m');

Or in mysql you can try like

$construct ="SELECT * from table WHERE MONTH(DataIntroducere) <= MONTH(CURDATE())";

And try to avoid mysql_* statements due to the entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_* , is officially deprecated as of PHP v5.5.0 and will be removed in the future .

There are two other MySQL extensions that you can better Use: MySQLi and PDO_MySQL , either of which can be used instead of ext/mysql .

Answer 2

The most sensible way to do it is to save the dates as unix timestamps. http://www.unixtimestamp.com/index.php

Most programming languages provide methods that return unix timestamp. You can then convert current month into a timestamp and do query like

SELECT * FROM table WHERE month < timestamp_of_current_month

Answer 3

$construct = "SELECT * FROM table WHERE DATE(DataIntroducere) <= DATE(NOW());

This is the (correct) one. And you don't have to care about YEAR(), MONTH(), CURDATE() or whatever.
