MYSQL：使用/G参数改变输出结果集的显示方式

在MYSQL命令行中使用/G参数，将输出按列显示。当需要看表中各字段的值时非常有用。

普通的SQL命令输出如下：

[sql]

mysql> select * from t_goods;

+------+------------+----------+------------+-----------------------------------

-----------------------------+

| id | goods_name | quantity | add_date | description

|

+------+------------+----------+------------+-----------------------------------

-----------------------------+

| 1 | MYSQL5 | 50 | 2012-12-12 | A book that has been read but is i

n good condition. See the seller’s listing for full details and descr iption of

any imperfections. |

+------+------------+----------+------------+-----------------------------------

-----------------------------+

下面是使用/G选项的输出：

[sql]

mysql> select * from t_goods /G

*************************** 1. row ***************************

id: 1

goods_name: MYSQL5

quantity: 50

add_date: 2012-12-12

description: A book that has been read but is in good condition. See t

he seller’s listing for full details and description of any imperfections.

注意：/G为大写字母，不可使用小写；使用/G参数后，SQL语句后可以不加分隔符，如果加分隔符，则会报“error:no query specified”的错误。

这样的显示效果与MYSQL命令的-E参数是一样的。使用-E参数后，结果集默认以列的方式显示：

[sql]

C:/Users/qxl>mysql -uroot -E
