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 ;

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。
表:
SHOW TABLE STATUS将列出所有的表。
使用过滤:
SHOW TABLE STATUS where name like 'table_123';
对于表和列:
show create table your_table_name
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
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;
