我有一个名为tes的表格视图。
+--------------+--------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------+--------------+------+-----+---------+-------+
| id_oba | int(11) | NO | | NULL | |
| nama_obat | varchar(120) | NO | | NULL | |
| satuan | varchar(20) | YES | | NULL | |
| stok_awal | int(5) | YES | | NULL | |
| persediaan | int(5) | YES | | NULL | |
| nama_suplier | varchar(30) | NO | | NULL | |
| pemakaian | int(4) | NO | | NULL | |
| tanggal | date | YES | | NULL | |
+--------------+--------------+------+-----+---------+-------+
执行时：
select id_oba, nama_obat, satuan, stok_awal, sum(pemakaian) AS pemakaian, persediaan,
from tes group by id_oba;
我得到了这个结果：
+--------+-----------+--------+-----------+-----------+------------+
| id_oba | nama_obat | satuan | stok_awal | pemakaian | persediaan |
+--------+-----------+--------+-----------+-----------+------------+
| 1 | Paramex | Botol | 30 | 40 | 5 |
| 2 | Oskadon | Botol | 30 | 41 | 27 |
| 3 | Lindon | Botol | 31 | 30 | 4 |
+--------+-----------+--------+-----------+-----------+------------+
如何修改我的查询以获得这样的结果？
+--------+-----------+--------+-----------+-----------+------------+-------+
| id_oba | nama_obat | satuan | stok_awal | pemakaian | persediaan | total |
+--------+-----------+--------+-----------+-----------+------------+-------+
| 1 | Paramex | Botol | 30 | 40 | 5 | 45 |
| 2 | Oskadon | Botol | 30 | 41 | 27 | 67 |
| 3 | Lindon | Botol | 31 | 30 | 4 | 34 |
+--------+-----------+--------+-----------+-----------+------------+-------+
请帮我解决我的问题。
感谢。

像这样改变
select id_oba, nama_obat, satuan, stok_awal, sum(pemakaian) AS pemakaian,
persediaan,(sum(pemakaian)+persediaan) as total from tes group by id_oba;
