1.mysql中的\G和\g；
2.值得注意的是直接在mysql工具里面执行会被转义成： select * from member limit 3G;导致直接报错。
3.直接在命令行执行是没有任何问题的如图：
(1).\g等价于;号,例如下面两条sql语句的输出结果是一样的:
select * from member limit 3 \g;
select * from member limit 3;
输出结果:
+----+-------+
| id | name |
+----+-------+
| 1 | zhang |
| 1 | zhang |
| 1 | zhang |
+----+-------+
3 rows in set (0.00 sec)
(2).\G是为了让输出结果纵向显示
select * from member limit 3\G;
输出结果:
*************************** 1. row ***************************
id: 1
name: zhang
*************************** 2. row ***************************
id: 1
name: zhang
*************************** 3. row ***************************
id: 1
name: zhang
