SHOW TABLE DOES在MySQL中显示什么信息
MySQL中的SHOW TABLE STATUS显示表的NAME、ENGINE、VERSION、ROWS、CHECKSUM等 -
示例
我们首先要创建一个表。这里,我们使用MyISAM引擎。创建表的查询如下 -
mysql> create table Post_Demo -> ( -> PostId int, -> PostName varchar(100), -> PostDate datetime, -> PRIMARY KEY(PostId) -> )ENGINE = MyISAM; Query OK, 0 rows affected (0.28 sec)
现在你可以使用SHOW TABLE命令检查表状态。查询如下 -
mysql> show table status where Name = 'Post_Demo'\G
输出
*************************** 1. row *************************** Name: post_demo Engine: MyISAM Version: 10 Row_format: Dynamic Rows: 0 Avg_row_length: 0 Data_length: 0 Max_data_length: 281474976710655 Index_length: 1024 Data_free: 0 Auto_increment: 1 Create_time: 2019-02-12 16:27:26 Update_time: 2019-02-12 16:27:26 Check_time: NULL Collation: utf8_general_ci Checksum: NULL Create_options: Comment: 1 row in set (0.00 sec)
