MySQL查询表字符集编码的两种方法
1、使用show table status语句查看指定表的字符集编码
SHOW TABLE STATUS命令可以获取指定数据库中每个数据表的信息，包括字符集编码。
show table status from 数据库名;
但只想获取指定表的信息，就可利用like进行限制：
show table status from 库名 like 表名;
示例：查看class_7数据库中test_info表的字符集编码
show table status from class_7 like 'test_info';
mysql> show table status from class_7 like 'test_info'; +-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+- | Name | Engine | Version | Row_format | Rows | Avg_row_length | Data_leate_time | Update_time | Check_time | Collation | Checksum | +-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+- | test_info | InnoDB | 10 | Compact | 10 | 1638 | 17-12-05 19:01:55 | NULL | NULL | utf8_general_ci | NULL | +-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+- 1 row in set (0.00 sec)
2、使用show columns语句配合full关键字查看当前数据库中指定表中所有列的字符集编码
在mysql中，SHOW COLUMNS命令可以显示表的列信息，而要获取有关列的更多信息，请将FULL关键字添加到SHOW COLUMNS命令中：
show full columns from 表名;
该语句可以输出指定表中所有列的字符集编码
示例：查看test_info表中所有列的字符集编码
show full columns from test_info;
mysql> show full columns from test_info; +-------+----------+-----------------+------+-----+---------+-------+---------------------------------+---------+ | Field | Type | Collation | Null | Key | Default | Extra | Privileges | Comment | +-------+----------+-----------------+------+-----+---------+-------+---------------------------------+---------+ | id | int(3) | NULL | NO | PRI | NULL | | select,insert,update,references | | | name | char(12) | utf8_general_ci | YES | | NULL | | select,insert,update,references | | | dorm | char(10) | utf8_general_ci | YES | | NULL | | select,insert,update,references | | | addr | char(12) | utf8_general_ci | YES | | 未知 | | select,insert,update,references | | | score | int(3) | NULL | YES | | NULL | | select,insert,update,references | | +-------+----------+-----------------+------+-----+---------+-------+---------------------------------+---------+ 5 rows in set (0.00 sec)
