mysql
介绍2种查询表字符集编码的方法。1、利用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;2、利用show table status
语句查看指定表的字符集编码。
1、利用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
show full columns from 表名;
mysql> show full columns from 表名; +-------+----------+-----------------+------+-----+---------+-------+---------------------------------+---------+ | 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)
2、利用show table status语句查看指定表的字符集编码
show table status from 库名 like 表名;
mysql> show table status from 库名 like 表名; +-----------+--------+---------+------------+------+----------------+-------------------------+-------------+------------+-----------------+----------+- | 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)
