Question

我有一张transactions表。

    id  account_id  trx_date    trx_type  amount  remarks  
------  ----------  ----------  --------  ------  ---------
     1           1  2017-12-10  DEPOSIT      500  test
     2           1  2017-12-11  DEPOSIT      500  test     
     3           1  2017-12-12  DEPOSIT     6000  test     
     4           1  2017-12-13  WITHDRAW     300  test     
     5           1  2017-12-13  DEPOSIT      200  test

我想产生这种格式，但我无法弄清楚如何获取数据，如下所示。这里所有字段都与transactions表相同。 op_bal，cl_bal是动态字段。

date            trx_type        op_bal      amount      cl_bal
2017-12-12      DEPOSIT         1000        6000            7000
2017-12-13      WITHDRAW        7000        300             6700
2017-12-13      DEPOSIT         6700        200             6900

你好我已创建this sqlfiddle的给定输出，请检查答案

Ratings::where([['class_id', '=', $class_id], ['id', '=', $rating_id]])
        ->update(['grade' => $grade, 'star' => $star, 'comment' => $comment]);

和查询实现结果是

CREATE TABLE transactions (
    id bigint(12) PRIMARY KEY auto_increment,
    account_id bigint(12),
    trx_date date,
    trx_type enum('DEPOSIT','WITHDRAW'),
    amount float(10,2),
    remarks varchar(50)
);

INSERT INTO transactions (account_id, trx_date, trx_type, amount, remarks)
VALUES ('1','2017-12-10','DEPOSIT',500,'test'),
       ('1','2017-12-11','DEPOSIT',500,'test'),
       ('1','2017-12-12','DEPOSIT',6000,'test'),
       ('1','2017-12-13','WITHDRAW',300,'test'),
       ('1','2017-12-13','DEPOSIT',200,'test');

希望它对你有用。
