以下均为查看mytable表的信息

1.查看表的存储引擎、记录数等

mysql> show table status like 'mytable' /G;*************************** 1. row ***************************           Name: mytable  #表名         Engine: InnoDB  #存储引擎伟InnoDB        Version: 10   #mysql版本     Row_format: Compact   #行格式。有Dynamic,fixed,Compact等格式。Dynamic是动态行,表字段里面宝航varchar,BloB等不定长字段。fixed是定长行。Compact是行压缩。           Rows: 0  #表中的行数 Avg_row_length: 0  #平均每行的字节数    Data_length: 16384   #整个表的数据量(字节)Max_data_length: 0  #表最大的容量。0表示无限   Index_length: 0    #索引数据占用磁盘空间的大小      Data_free: 10485760  #表示已分配但还未被使用的空间大小。 Auto_increment: NULL  #下一个AUto_increment的值    Create_time: 2011-08-06 22:39:46  #创建时间    Update_time: NULL  #更新时间     Check_time: NULL  #使用check table等命令时的检查时间      Collation: utf8_general_ci  #默认字符集和字符列排列顺序       Checksum: NULL  #如果启动,则表示整个表的校验和 Create_options: max_rows=4294967295 avg_row_length=32  #表创建时的选项        Comment: 1 row in set (0.00 sec)
