表:

SHOW TABLE STATUS将列出所有的表。

使用过滤:

SHOW TABLE STATUS where name like 'table_123';

数据库: 使用db_name;选择@@character_set_database;

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  |

要查看数据库的默认排序规则:

USE db_name;
SELECT @@character_set_database, @@collation_database;

要查看表格的排序:

SHOW TABLE STATUS where name like 'table_name';

要查看列的排序规则:

SHOW FULL COLUMNS FROM table_name;

查看表的默认字符集

SHOW CREATE TABLE table_name;

数据库:

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