sql - 如何查看MySQL数据库/表/列的字符集？

(默认)字符集是什么:

MySQL数据库

MySQL表

MySQL列

最佳答案

这是我的做法-

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";

对于表:

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";

对于列:

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