使用選擇我有表姓名jual
我怎樣才能查詢從表在MySQL
Field | Type | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+-------+
| id_jual | int(11) | NO | PRI | NULL | |
| tanggal | date | YES | | NULL | |
| jumlah | int(4) | NO | | NULL | |
| id_obat | int(11) | YES | MUL | NULL | |
| id_periksa | int(11) | YES | MUL | NULL | |
| pemakaian | varchar(30) | YES | | NULL | |
當我執行select * from jual
「在這裏結果」
id_jual | tanggal | jumlah | id_obat | id_periksa | pemakaian |
+---------+------------+--------+---------+------------+-----------+
| 1 | 2014-10-29 | 20 | 1 | 1 | 3x1 |
| 2 | 2014-10-29 | 10 | 5 | 1 | 2x1 |
| 5 | 2014-10-29 | 20 | 8 | 2 | 2x1 |
| 6 | 2014-10-29 | 20 | 1 | 3 | 3x1 |
| 10 | 2014-10-29 | 13 | 5 | 4 | 2x1 |
| 11 | 2014-10-29 | 10 | 8 | 4 | 2x1 |
| 12 | 2014-10-29 | 30 | 1 | 5 | 2x1 |
| 15 | 2014-10-29 | 30 | 3 | 6 | 21 |
| 16 | 2014-10-29 | 20 | 8 | 6 | 3x1 |
| 18 | 2014-10-29 | 30 | 3 | 7 | 1x2 |
| 22 | 2014-10-30 | 20 | 3 | 9 | 1x2 |
| 39 | 2014-10-30 | 10 | 3 | 18 | 1x1 |
| 43 | 2014-10-31 | 15 | 3 | 20 | 2x1 |
| 46 | 2014-10-31 | 10 | 5 | 21 | 2x1 |
| 47 | 2014-11-01 | 20 | 6 | 22 | 1x1 |
| 50 | 2014-11-01 | 7 | 6 | 23 | 1x1 |
我怎樣才能得到這樣的結果視圖這樣的:
id_obat | tanggal
+---------+------------+----------+----------+----------+-----------+
2014-10-29 |2014-10-30|2014-10-31|2014-11-01|2014-11-02
+---------+------------+----------+----------+----------+-----------+
| 1 | 20.20.30 | | | | |
| 3 | 30.30 | 20.10 | 15 | | |
| 5 | 10.13 | | 10. | | |
| 6 | | | 20.7 | | |
| 8 | 20.10.20 | | | | |
+---------+------------+----------+----------+----------+------------+
