表:

SHOW TABLE STATUS将列出所有的表。

使用过滤:

SHOW TABLE STATUS where name like 'table_123';

正如前面所写的，SHOW FULL COLUMNS应该是获取列信息的首选方法。 缺少的是在不直接到达元数据表的情况下获取字符集的方法:

SHOW FULL COLUMNS FROM my_table WHERE Field = 'my_field'
SHOW COLLATION WHERE Collation = 'collation_you_got'

我总是看SHOW CREATE TABLE mydatabase。mytable。

对于数据库，似乎需要查看SELECT DEFAULT_CHARACTER_SET_NAME FROM information_schema.SCHEMATA。

我是这么做的——

对于模式(或数据库-它们是同义词):

SELECT default_character_set_name FROM information_schema.SCHEMATA 
WHERE schema_name = "schemaname";

表:

SELECT CCSA.character_set_name FROM information_schema.`TABLES` T,
       information_schema.`COLLATION_CHARACTER_SET_APPLICABILITY` CCSA
WHERE CCSA.collation_name = T.table_collation
  AND T.table_schema = "schemaname"
  AND T.table_name = "tablename";

列:

SELECT character_set_name FROM information_schema.`COLUMNS` 
WHERE table_schema = "schemaname"
  AND table_name = "tablename"
  AND column_name = "columnname";

数据库:

只需使用这些命令:

USE db_name;
SELECT @@character_set_database;
-- or:
-- SELECT @@collation_database;

SELECT TABLE_SCHEMA,
       TABLE_NAME,
       CCSA.CHARACTER_SET_NAME AS DEFAULT_CHAR_SET,
       COLUMN_NAME,
       COLUMN_TYPE,
       C.CHARACTER_SET_NAME
  FROM information_schema.TABLES AS T
  JOIN information_schema.COLUMNS AS C USING (TABLE_SCHEMA, TABLE_NAME)
  JOIN information_schema.COLLATION_CHARACTER_SET_APPLICABILITY AS CCSA
       ON (T.TABLE_COLLATION = CCSA.COLLATION_NAME)
 WHERE TABLE_SCHEMA=SCHEMA()
   AND C.DATA_TYPE IN ('enum', 'varchar', 'char', 'text', 'mediumtext', 'longtext')
 ORDER BY TABLE_SCHEMA,
          TABLE_NAME,
          COLUMN_NAME
;
