现在有两个表格,用来演示表格的内连接、做连接及右连接;
A表 B表
id | name |
1 | a |
2 | b |
3 | c |
4 | d |
5 | e |
id | name |
1 | 白 |
2 | 黑 |
3 | 红 |
4 | 绿 |
5 | 蓝 |
内连接:select * from A,B where A.id=B.id与Select * from A JOIN B ON A.id=B.id
结果
id | name | id | name |
1 | a | 1 | 白 |
2 | b | 2 | 黑 |
3 | c | 3 | 红 |
4 | d | 4 | 绿 |
5 | e | 5 | 蓝 |
