Question

我有一个新问题，作为我之前的问题的信息，我已经成功显示加入另一个表的4 coloumn，但我有另一个问题显示另一个coloumn /字段，更详细：

表格个人（tbl_personal）

+---+-----+------------+
|ID |Name |Skill       |
+---+-----+------------+
| 1 | Nia | Accountant |
| 2 | Tia | Banking    |
| 3 | Ria | Technicall |
| 4 | Dia | Admin      |
+---+-----+------------+

表大师（tbl_master）

+---+---------+---------+-----------+--------+----+
|ID |Employee1|Employee2|Departement|Division|Note|
+---+---------+---------+-----------+--------+----+
| 1 | 1       | 2       | MSO       | MWS    | etc|
| 2 | 2       | 1       | DSO       | SE     | etc|
| 3 | 3       | 4       | OSO       | GA     | etc|
+---+---------+---------+-----------+--------+----+

我想在codeigniter中显示上面的tbl_master网页，如下所示：

+---+-------+-----------+-------+-----------+-----------+--------+----+
|ID |Name 1 |Skill 1    |Name 2 |Skill 2    |Departement|Division|Note|
+---+-------+-----------+-------+-----------+-----------+--------+----+
| 1 | Nia   | Accountant| Tia   | Banking   | MSO       | MWS    | etc|
| 2 | Tia   | Banking   | Nia   | Accountant| DSO       | SE     | etc|
| 3 | Ria   | Technicall| Dia   | Admin     | OSO       | GA     | etc|
+---+---------+---------+-------+-----------+-----------+--------+----+

我已经有了解决方案，使用此代码显示名称1，技能1直到技能2：

select tp1.name name1,tp1.skill skill1,tp2.name name2,tp2.skill skill2 
from tbl_master tm
join tbl_personal tp1
on tm.Employee1 =tp1.ID
join tbl_personal tp2
on tm.Employee2 =tp2.ID

但我还有另一个问题是显示离开，分区和注释字段，如果有任何建议，请，谢谢......

Answer 1

您只需更改您的选择并添加这些列：

select tp1.name name1,tp1.skill skill1,tp2.name name2,tp2.skill skill2,tm.Departement, tm.Division, tm.Note
from tbl_master tm
join tbl_personal tp1
on tm.Employee1 =tp1.ID
join tbl_personal tp2
on tm.Employee2 =tp2.ID

将表连接到4个列并显示另一个字段
