mysql中\G的作用

使用\G按行垂直显示结果

在SQL语句或者命令后使用\G而不是分号结尾，可以将每一行的值垂直输出

mysql> show create table log \G
*************************** 1. row ***************************
       Table: log
Create Table: CREATE TABLE `log` (
  `logId` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `uName` varchar(255) NOT NULL,
  `logIp` varchar(255) NOT NULL,
  `logTime` datetime NOT NULL,
  `handout` int(10) unsigned NOT NULL DEFAULT '0' COMMENT '电子讲义  0:无讲义，1:有讲义。默认为0',
  PRIMARY KEY (`logId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
1 row in set (0.00 sec)

注：\g的作用和sql语句后面的分号类似，水平显示查询数据

mysql> show create table log \g
