How do I see what character set a MySQL database / table / column is?

Question

What is the (default) charset for:

• MySQL database

• MySQL table

• MySQL column

Answer 1

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";
