数据库: 使用db_name;选择@@character_set_database;

数据库:

USE your_database_name;
show variables like "character_set_database";
-- or:
-- show variables like "collation_database";

参考本页。查阅MySQL手册

对于表和列:

show create table your_table_name

对于服务器上的所有数据库:

mysql> SELECT SCHEMA_NAME 'database', default_character_set_name 'charset', DEFAULT_COLLATION_NAME 'collation' FROM information_schema.SCHEMATA;

输出:

+----------------------------+---------+--------------------+
| database                   | charset | collation          |
+----------------------------+---------+--------------------+
| information_schema         | utf8    | utf8_general_ci    |
| my_database                | latin1  | latin1_swedish_ci  |
...
+----------------------------+---------+--------------------+

对于单个数据库:

mysql> USE my_database;
mysql> show variables like "character_set_database";

输出:

    +----------------------------+---------+
    | Variable_name              |  Value  |
    +----------------------------+---------+
    | character_set_database     |  latin1 | 
    +----------------------------+---------+

获取表的排序规则:

mysql> USE my_database;
mysql> SHOW TABLE STATUS WHERE NAME LIKE 'my_tablename';

OR -将输出创建表的完整SQL语句:

Mysql >创建表my_tablename

获取列的排序规则:

mysql> SHOW FULL COLUMNS FROM my_tablename;

输出:

+---------+--------------+--------------------+ ....
| field   | type         | collation          |
+---------+--------------+--------------------+ ....
| id      | int(10)      | (NULL)             |
| key     | varchar(255) | latin1_swedish_ci  |
| value   | varchar(255) | latin1_swedish_ci  |
+---------+--------------+--------------------+ ....

数据库:

SELECT SCHEMA_NAME 'database', default_character_set_name 'charset', DEFAULT_COLLATION_NAME 'collation' FROM information_schema.SCHEMATA;

示例输出:

mysql> SELECT SCHEMA_NAME 'database', default_character_set_name 'charset', DEFAULT_COLLATION_NAME 'collation' FROM information_schema.SCHEMATA;
+----------------------------+---------+--------------------+
| database                   | charset | collation          |
+----------------------------+---------+--------------------+
| information_schema         | utf8    | utf8_general_ci    |
| drupal_demo1               | utf8    | utf8_general_ci    |
| drupal_demo2               | utf8    | utf8_general_ci    |
| drupal_demo3               | utf8    | utf8_general_ci    |
| drupal_demo4               | utf8    | utf8_general_ci    |
| drupal_demo5               | latin1  | latin1_swedish_ci  |

...

mysql> 

表:

SHOW TABLE STATUS将列出所有的表。

使用过滤:

SHOW TABLE STATUS where name like 'table_123';
