方法：1、“show charset”語句，查看MYSQL所支持的字符集；2、“show create database 庫名G”語句，查看庫的字符集；3、“show full columns from 表名”，查看表中所有列的字符集。

本教程操作環境：windows7系統、mysql8版本、Dell G3電腦。

查看字符集

1、查看MYSQL數據庫服務器和數據庫字符集

方法一：show variables like '%character%'; 方法二：show variables like 'collation%';

方法一：

mysql> show variables like '%character%'; +--------------------------+--------------------------------------+ | Variable_name            | Value                                | +--------------------------+--------------------------------------+ | character_set_client     | utf8                                 | | character_set_connection | utf8                                 | | character_set_database   | utf8                                 | | character_set_filesystem | binary                               | | character_set_results    | utf8                                 | | character_set_server     | utf8                                 | | character_set_system     | utf8                                 | | character_sets_dir       | /usr/local/mysql5535/share/charsets/ | +--------------------------+--------------------------------------+ 8 rows in set (0.00 sec)

方法二：

mysql> show variables like 'collation%'; +----------------------+-----------------+ | Variable_name        | Value           | +----------------------+-----------------+ | collation_connection | utf8_general_ci | | collation_database   | utf8_general_ci | | collation_server     | utf8_general_ci | +----------------------+-----------------+ 3 rows in set (0.00 sec)

2、查看MYSQL所支持的字符集

使用show charset可查看MYSQL所支持的字符集

mysql> show charset; +----------+-----------------------------+---------------------+--------+ | Charset  | Description                 | Default collation   | Maxlen | +----------+-----------------------------+---------------------+--------+ | big5     | Big5 Traditional Chinese    | big5_chinese_ci     |      2 | | dec8     | DEC West European           | dec8_swedish_ci     |      1 | | cp850    | DOS West European           | cp850_general_ci    |      1 | | hp8      | HP West European            | hp8_english_ci      |      1 | | koi8r    | KOI8-R Relcom Russian       | koi8r_general_ci    |      1 | | latin1   | cp1252 West European        | latin1_swedish_ci   |      1 | | latin2   | ISO 8859-2 Central European | latin2_general_ci   |      1 | | swe7     | 7bit Swedish                | swe7_swedish_ci     |      1 | | ascii    | US ASCII                    | ascii_general_ci    |      1 | | ujis     | EUC-JP Japanese             | ujis_japanese_ci    |      3 | | sjis     | Shift-JIS Japanese          | sjis_japanese_ci    |      2 | | hebrew   | ISO 8859-8 Hebrew           | hebrew_general_ci   |      1 | | tis620   | TIS620 Thai                 | tis620_thai_ci      |      1 | | euckr    | EUC-KR Korean               | euckr_korean_ci     |      2 | | koi8u    | KOI8-U Ukrainian            | koi8u_general_ci    |      1 | | gb2312   | GB2312 Simplified Chinese   | gb2312_chinese_ci   |      2 | | greek    | ISO 8859-7 Greek            | greek_general_ci    |      1 | | cp1250   | Windows Central European    | cp1250_general_ci   |      1 | | gbk      | GBK Simplified Chinese      | gbk_chinese_ci      |      2 | | latin5   | ISO 8859-9 Turkish          | latin5_turkish_ci   |      1 | | armscii8 | ARMSCII-8 Armenian          | armscii8_general_ci |      1 | | utf8     | UTF-8 Unicode               | utf8_general_ci     |      3 | | ucs2     | UCS-2 Unicode               | ucs2_general_ci     |      2 | | cp866    | DOS Russian                 | cp866_general_ci    |      1 | | keybcs2  | DOS Kamenicky Czech-Slovak  | keybcs2_general_ci  |      1 | | macce    | Mac Central European        | macce_general_ci    |      1 | | macroman | Mac West European           | macroman_general_ci |      1 | | cp852    | DOS Central European        | cp852_general_ci    |      1 | | latin7   | ISO 8859-13 Baltic          | latin7_general_ci   |      1 | | utf8mb4  | UTF-8 Unicode               | utf8mb4_general_ci  |      4 | | cp1251   | Windows Cyrillic            | cp1251_general_ci   |      1 | | utf16    | UTF-16 Unicode              | utf16_general_ci    |      4 | | cp1256   | Windows Arabic              | cp1256_general_ci   |      1 | | cp1257   | Windows Baltic              | cp1257_general_ci   |      1 | | utf32    | UTF-32 Unicode              | utf32_general_ci    |      4 | | binary   | Binary pseudo charset       | binary              |      1 | | geostd8  | GEOSTD8 Georgian            | geostd8_general_ci  |      1 | | cp932    | SJIS for Windows Japanese   | cp932_japanese_ci   |      2 | | eucjpms  | UJIS for Windows Japanese   | eucjpms_japanese_ci |      3 | +----------+-----------------------------+---------------------+--------+ 39 rows in set (0.00 sec)

3、查看庫的字符集

語法：show create database 數據庫G;

mysql> show create database shiyanG *************************** 1. row ***************************        Database: shiyan Create Database: CREATE DATABASE `shiyan` /*!40100 DEFAULT CHARACTER SET gbk */ 1 row in set (0.00 sec)

4、查看表的字符集

語法：show table status from 庫名 like 表名;

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)

5、查看表中所有列的字符集

語法：show full columns from 表名;

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)
