如何从去年MySQL进入

Question

这部分查询似乎不起作用

$iThisYear = date('Y');
$iLastYear = $iThisYear-1;

SELECT * FROM `{$this->_sPrefix}clicks` 
WHERE `affiliate_id` = '{$iAid}' 
AND `raw` = '1' 
AND YEAR(`date`) = '{$iLastYear}'

它仍然从今年开始夺冠.YEAR有效吗？

Answer 1

你可以改用DATE_SUB吗？

SELECT * FROM `{$this->_sPrefix}clicks` 
WHERE `affiliate_id` = '{$iAid}' 
AND `raw` = '1' 
AND YEAR(`date`) = YEAR(DATE_SUB(CURDATE(), INTERVAL 1 YEAR))
