MySQL 数据库表:
CREATE TABLE `transactions` (
`trx_id` int(11) NOT NULL AUTO_INCREMENT,
`trx_type` enum('debit','credit') DEFAULT NULL,
`trx_amount` float DEFAULT NULL,
`trx_description` mediumtext NOT NULL,
`trx_date` date NOT NULL,
`purpose_id` int(11) NOT NULL,
`staff_id` int(11) DEFAULT NULL,
`admin_id` int(11) NOT NULL,
`created_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
`updated_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`trx_id`)
) ENGINE=InnoDB AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;
/*表transactions
的数据*/
insert into `transactions`(`trx_id`,`trx_type`,`trx_amount`,`trx_description`,`trx_date`,`purpose_id`,`staff_id`,`admin_id`,`created_at`,`updated_at`)

MySQL 查询:
SELECT trx_id,staff_id
, SUM(COALESCE(CASE WHEN trx_type = 'debit' THEN trx_amount END,0)) total_debits
, SUM(COALESCE(CASE WHEN trx_type = 'credit' THEN trx_amount END,0)) total_credits
, SUM(COALESCE(CASE WHEN trx_type = 'debit' THEN trx_amount END,0))
- SUM(COALESCE(CASE WHEN trx_type = 'credit' THEN trx_amount END,0)) balance
FROM erp_transactions GROUP BY staff_id HAVING balance <> 0 ORDER BY trx_id;
输出结果:
【问题讨论】:
出了什么问题,你想要什么? 你能解释一下你到底想做什么吗? 您的意思是无效的借方和贷方值在逻辑上显示为前两行不应为负数? @hunter balance 2nd row will be +100 余额是否为流动余额? 【参考方案1】: select s.*,
s.debit - s.credit as Balance,
@RunningBalance:= @RunningBalance + s.debit - s.credit RunningBalance
from
(
select min(trx_id) trx_id,t.staff_id,
sum(case when trx_type = 'debit' then trx_amount else 0 end) as Debit,
sum(case when trx_type = 'credit' then trx_amount else 0 end) as Credit
from trans t
group by staff_id
order by trx_id
) s,
(Select @RunningBalance:=0) rb
order by s.trx_id
结果
+--------+----------+-------+--------+---------+----------------+
| trx_id | staff_id | Debit | Credit | Balance | RunningBalance |
+--------+----------+-------+--------+---------+----------------+
| 1 | 7 | 0 | 100 | -100 | -100 |
| 2 | 5 | 200 | 0 | 200 | 100 |
