如何查看 MySQL 数据库/表/列的字符集是什么?

What is the (default) charset for:

• MySQL database

• MySQL table

• MySQL column

解决方案

Here's how I'd do it -

For Schemas (or Databases - they are synonyms):

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

For Tables:

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";

For Columns:

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