Selezionare gli ultimi 7 giorni da Ora() in MySQL

Question

Grazie per aver dedicato del tempo a guardare la mia domanda.

ho questa query MySQL:

foreach($wpdb->get_results(
    "SELECT wp_pixelcart_calendar.datefield AS DATE, 
    IFNULL(SUM(wp_pixelcart_daily_sales.quantity),0) AS total_sales 
    FROM wp_pixelcart_daily_sales RIGHT JOIN wp_pixelcart_calendar ON (DATE(wp_pixelcart_daily_sales.order_date) = wp_pixelcart_calendar.datefield) 
    WHERE (wp_pixelcart_calendar.datefield BETWEEN (SELECT MIN(DATE(order_date)) FROM wp_pixelcart_daily_sales) AND (SELECT MAX(DATE(order_date)) FROM wp_pixelcart_daily_sales)) 
    GROUP BY DATE" 
) as $key => $row) { 

echo "<br>". $row->DATE . "',". $row->total_sales . "],"; 

} 

Sto avendo un momento difficile per visualizzare gli ultimi sette giorni da oggi nella query, Ive stato a giocare con:

BETWEEN (SELECT MIN(DATE(order_date)) FROM wp_pixelcart_daily_sales) AND (SELECT MAX(DATE(order_date)) FROM wp_pixelcart_daily_sales)) 

Per this:

BETWEEN NOW() FROM wp_pixelcart_daily_sales) AND DATE_ADD(NOW(), INTERVAL 7 DAY) FROM wp_pixelcart_daily_sales)) 

Ma questo non sembra funzionare.

Qualsiasi aiuto apprezzato.

Grazie

Answer 1

se questo non funziona, di ritorno 0, considerano scambiando gamma le date:

BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW() 

Answer 2

WHERE order_date <= NOW() AND order_date >= DATE_SUB(order_date, INTERVAL 7 DAY) 

Answer 3

si può solo scrivere:

SELECT * FROM table WHERE date_field > DATE_SUB(NOW(), INTERVAL 7 DAY)
