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]:常规错误

$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,它的工作原理:

$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"
                            );

*注意:查询是在phpmyadmin中直接测试的,没有错误.

Answer 1

似乎在MySql中设置变量被认为是一个单独的查询.(fetch*()无法处理多个调用)

对于那些有这类问题的人:

$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"
                            );
