동일한 열 선택 2 테이블에서보기의 1 열로

Question

다른 테이블에 같은 이름의 열이 두 개 있습니다. 보기의 한 열에 그들을 결합하고 싶습니다.

여기 내 첫 번째 테이블 stocks :

+----------+------------+------------+---------+----------------+--------+ 
| stock_id | stock_cost | stock_left | item_id | purchasedtl_id | trx_id | 
+----------+------------+------------+---------+----------------+--------+ 
|  1 |  1000 |   0 |  1 |    1 |  1 | 
|  2 |  1000 |   5 |  1 |    2 |  2 | 
|  3 |  1000 |   1 |  1 |    3 |  4 | 
+----------+------------+------------+---------+----------------+--------+ 

두 번째 테이블 stocks_out

+-------------+----------------+--------------+---------+----------+------------+--------+ 
| stockout_id | stockout_price | stockout_qty | item_id | stock_id | saledtl_id | trx_id | 
+-------------+----------------+--------------+---------+----------+------------+--------+ 
|   1 |   2000 |   1 |  1 |  1 |   1 |  3 | 
+-------------+----------------+--------------+---------+----------+------------+--------+ 

그리고이 trx_id, trx_no, trx_closetime, trx_type stock_id, stock_cost, stockout_id, stock_out_cost, stockout_price, item_id

item_id처럼되고 그들과 합류 할 것은 내가 가입 할 분야입니다 한 칸에.

select `transactions`.`trx_id` AS `trx_id`,`transactions`.`trx_no` AS `trx_no`,`transactions`.`trx_closetime` AS `trx_closetime`,`transactions`.`trx_type` AS `trx_type`,`stocks`.`stock_id` AS `stock_id`,`stocks`.`stock_cost` AS `stock_cost`,`stock_out`.`stockout_id` AS `stockout_id`,`stock_out`.`stockout_price` AS `stockout_price` from ((`transactions` left join `stocks` on(`stocks`.`trx_id` = `transactions`.`trx_id`)) left join `stock_out` on(`stock_out`.`trx_id` = `transactions`.`trx_id`)) order by `transactions`.`trx_closetime`; 

그리고 현재의 결과 :

현재 쿼리는

+--------+---------------------+---------------------+----------+----------+------------+-------------+----------------+ 
| trx_id | trx_no    | trx_closetime  | trx_type | stock_id | stock_cost | stockout_id | stockout_price |
