Question

我需要得到今天，昨天和前天生日的人。

我正在使用yii2和postgresql，但我收到了错误

SQLSTATE[HY093]: Invalid parameter number: :dayBind
Failed to prepare SQL: select name from employee
where date_part('day', born_date) = ':dayBind' and date_part('month', born_date) = ':monthBind'
Error Info: Array
(
    [0] => HY093
    [1] => 0
)

我不知道我在这段代码中做错了什么

 $days = array('day before yesterday' => date('m/d',  strtotime("-2 days"))
             , 'yesterday' => date('m/d',  strtotime("-1 days"))
             , 'today' => date('m/d')
 );

 $sql = "select name from employee
            where date_part('day', born_date) = ':dayBind' and date_part('month', born_date) = ':monthBind'";

 $result = array();
 foreach($days as $definition => $date) {

        list($m, $d) = explode("/", $date);

        $params = array(':dayBind' => $d, ':monthBind' => $m);

        $result[$definition] = Yii::$app->db->createCommand($sql)->bindValues($params)->queryAll();
 }

Answer 1

删除bind param上的单引号像这样：

$sql = "select name from employee where date_part('day', born_date) = :dayBind and date_part('month', born_date) = :monthBind";

Yii2 - HY093中的查询错误
