Question

任何人都可以帮助使用事务我有查询在事务中创建表但它无法回滚并创建2表而在1查询中出错。

这是我的控制器：

 public function transaction_sample(){
    $this->data["title"] = get_class($this);

    /*
     * for public_transact_query in module library
     */

    //sample comet id
    $comet_id= $this->module->gen_password(9);


    //concatenate the get_camera_+comet_id
    $get_camera_name = "get_camera_".strtolower($comet_id);
    // adding table for get_camera
    $add_table_get_camera ="CREATE TABLE `".$get_camera_name."` (
                              `get_cam_key` varchar(16) DEFAULT NULL,
                              `get_cam_date` datetime DEFAULT NULL,
                              `get_cam_id` bigint(30) DEFAULT NULL,
                              `get_cam_cnt` int(5) DEFAULT NULL,
                              `get_cam_line` int(5) DEFAULT NULL,
                              `get_cam_loc` enum('door','aisle','back') DEFAULT NULL,
                              `get_cam_chunk` varchar(1024) DEFAULT NULL,
                              `get_cam_ip` varchar(16) DEFAULT NULL,
                              `get_cam_sysdate` timestamp NULL DEFAULT CURRENT_TIMESTAMP
                            );";

    // concatenate the get_telemetry_+comet_id
    $get_telemetry_name = "get_telemetry_".strtolower($comet_id);
    // adding table for get_camera
    $add_table_get_telemetry = "CREATE TABLE `".$get_telemetry_name."` (
                                  `get_tel_datetime` datetime NOT NULL,
                                  `get_route_id` int(11) DEFAULT NULL,
                                  `get_drvr_id` int(11) DEFAULT NULL,
                                  `get_routestn_id` int(11) DEFAULT NULL,
                                  `get_tel_ip` varchar(16) DEFAULT NULL,

                                  `get_tel_batv` int(3) DEFAULT NULL,
                                  `get_tel_bats` int(1) DEFAULT NULL,
                                  `get_tel_batc` int(3) DEFAULT NULL,
                                  `get_tel_volt` int(3) DEFAULT NULL,
                                  `get_tel_tito` int(1) DEFAULT NULL,
                                  `get_tel_chrgt` int(3) DEFAULT NULL,
                                  `get_tel_ctrlt` int(3) DEFAULT NULL,
                                  `get_tel_mtrt` int(3) DEFAULT NULL,
                                  `get_tel_sysdate` timestamp NULL DEFAULT CURRENT_TIMESTAMP
                                );";

    // concatenate the get_tito_+comet_id
    //DROP TABLE IF EXISTS `".$get_tito_name."`;
    $get_tito_name = "get_tito_".strtolower($comet_id);
    //adding table for get_tito
    $add_table_get_tito="CREATE TABLE `".$get_tito_name."` (
                          `get_drvr_id` int(11) DEFAULT NULL,
                          `get_tito_key` varchar(16) DEFAULT NULL,
                          `get_tito_logdate` datetime DEFAULT NULL,
                          `get_tito_pair` varchar(16) DEFAULT NULL,
                          `get_tito_cardno` varchar(12) DEFAULT NULL,
                          `get_routestn_id` int(11) DEFAULT NULL,
                          `get_tito_load` decimal(9,2) DEFAULT '0.00',
                          `get_tito_fare` decimal(9,2) DEFAULT '0.00',
                          `get_tito_bal` decimal(9,2) DEFAULT '0.00',
                          `get_tito_type` int(1) DEFAULT NULL,
                          `get_tito_passcnt` int(2) DEFAULT NULL,
                          `get_tito_ip` varchar(16) DEFAULT NULL,
                          `get_tito_sysdate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP
                        );";    
    $queryList  = array(
                    "query3" => $add_table_get_camera,
                    "query4" => $add_table_get_telemetry,
                    "query5" => $add_table_get_tito
                );
    $this->module->public_transact_query($queryList,"Successfully Added");
    $this->load->view("view",$this->data);
}

我的图书馆：

    public function public_transact_query($queryList,$msg="Successfully Save/Add",$return_json=true){
    $this->ci->db->trans_begin();
    $isOk = false; 
    foreach ($queryList as $query => $query_value){
        $this->ci->db->query($query_value);
    }
    if($this->ci->db->trans_status() === FALSE){
        $msg =$this->ci->db->_error_message();
        $this->ci->db->trans_rollback();
        $isOk = false;
    }else{
        print_r($this->ci->db->trans_commit());
        //$isOk = true;
    }
    // if($return_json){
        // $this->my_return($isOk,$msg);
    // }else{
        // return $this->return_object($isOk,$msg);
    // }    
}

但它在更新，插入，删除sql语句时有效。请提前告知您

我已经完成了我的问题，这就是为什么create table没有回滚

创建表时，事务在Codeigniter中不起作用
