Today I will show you how to query the character set of mysql. The content of the article is good. Now I would like to share it with you. Friends who feel in need can understand it. I hope it will be helpful to you. Let's read it along with the editor's ideas.
Methods: 1, "show charset" statement to view the character set supported by MYSQL; 2, "show create database library name\ G" statement to view the character set of the library; 3, "show full columns from table name" to view the character set of all columns in the table.
The operating environment of this tutorial: windows7 system, mysql8 version, Dell G3 computer.
View character set
1. View MYSQL database server and database character set
Method 1: show variables like'% character%'; method 2: show variables like 'collation%'; method 1:
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)
Method 2:
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. View the character sets supported by MYSQL
Use show charset to view the character sets supported by MYSQL
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. View the character set of the library
Syntax: show create database database\ G
Mysql > show create database shiyan\ gateway * 1. Row * * Database: shiyanCreate Database: CREATE DATABASE `shiyan` / *! 40100 DEFAULT CHARACTER SET gbk * / 1 row in set (0.00 sec)
4. View the character set of the table
Syntax: show table status from library name like table name
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. View the character set of all the columns in the table
Syntax: show full columns from table name
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 | unknown | select,insert,update | References | | score | int (3) | NULL | YES | | NULL | | select,insert,update References | | +-+-- +-+ 5 rows In set (0.00 sec) above is how to query the full contents of the character set of mysql.
