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;

数据库:

SHOW CREATE DATABASE "DB_NAME_HERE";

在创建数据库(MySQL)时，默认字符集/排序规则总是LATIN，而不是在最初创建数据库时选择了不同的字符集/排序规则

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。

数据库: 使用db_name;选择@@character_set_database;
