mysql - 使用 mysql 变量的 Mysql 查询在 Zend Framework 1 中不起作用

Question

Zend 配置是：resources.db.adapter = "pdo_mysql"

获取 消息的查询：SQLSTATE [HY000]：一般错误

$db = Zend_Db_Table::getDefaultAdapter();
        $db->setFetchMode(Zend_Db::FETCH_ASSOC);       


        $qry =  $db->fetchAll(" SET @rank = 0 ;
                                SELECT
                                   @rank := @rank +1 AS rank,
                                    SUM(user_scoring_data.user_points)  AS user_points,
                                    league_team.user_id

                                FROM league_team 
                                RIGHT JOIN user_scoring_data ON league_team.league_team_id = user_scoring_data.league_team_id

                                WHERE league_id = '$league_id' GROUP BY user_scoring_data.league_team_id 
                                ORDER BY user_points DESC"
                            );

如果我删除 mysql 变量，它可以工作：

$db->fetchAll("
                                SELECT
                                    SUM(user_scoring_data.user_points)  AS user_points,
                                    league_team.user_id

                                FROM league_team 
                                RIGHT JOIN user_scoring_data ON league_team.league_team_id = user_scoring_data.league_team_id

                                WHERE league_id = '$league_id' GROUP BY user_scoring_data.league_team_id 
                                ORDER BY user_points DESC"
                            );

*注：查询直接在phpmyadmin中测试，没有错误。

Answer 1

似乎在 MySql 中设置一个变量被认为是一个单独的查询。（ fetch*() 不能处理多个调用）

所以对于那些有这种问题的人：

$db->query("SET @rank = 0 ;");

$db->fetchAll("SELECT
                                   @rank := @rank +1 AS rank,
                                    SUM(user_scoring_data.user_points)  AS user_points,
                                    league_team.user_id

                                FROM league_team 
                                RIGHT JOIN user_scoring_data ON league_team.league_team_id = user_scoring_data.league_team_id

                                WHERE league_id = '$league_id' GROUP BY user_scoring_data.league_team_id 
                                ORDER BY user_points DESC"
                            );
