Select everything older than 48 hours

Question

I am trying to display user comments from a database that are older than 2 days. This is so I can screen the comments before they appear on the site. The date is entered into the database using CURDATE()

I have tried multiple ways to get this to work, but no joy so far, here's my line of code that tries to compare the dates.

$comments = "SELECT comments, initial, surname, theDate " . 
            "FROM tbl " . 
            "WHERE comments IS NOT NULL AND " . 
            "theDate < (unix_timestamp(CURDATE() - interval 2 day)) " .
            "ORDER BY theDate DESC";

Everything gets displayed using this method.

Answer 1

Try to use DATEDIFF() MySQL function:

SELECT 
    comments, initial, surname, theDate
FROM
    tbl
WHERE
    comments IS NOT NULL
    AND
    DATEDIFF(NOW(), theDate) > 2
ORDER BY theDate DESC

Answer 2

使用：NOT CURWATE（） - INTERVAL 2 DAY和CURDATE（），这应该可以让你获得超过2天的所有东西
