MySQL的。如何在其他表中按订单排序

Question

我有：

SELECT * FROM '.PRFX.'sell
WHERE draft = "0" AND id
IN ( SELECT id_ FROM '.PRFX.'skipped
     WHERE uid = "'.$u.'" )

我想从ID field (DESC)

'.PRFX.'skipped'订购

怎么做？

Answer 1

您可以使用左连接：

SELECT   DISTINCT * 
FROM     '.PRFX.'sell sell
JOIN     '.PRFX.'skipped skip ON skip.id_ = sell.id
WHERE    draft = "0" AND skip.uid = "'.$u.'"
ORDER BY skip.id DESC
