mysql charecter set 설정 (DB 글자깨짐)

한글 등록시 글자 깨질때 DB의 character set을 확인해 보자.

1. 확인

1) SHOW CHARACTER SET;

2) DB 확인

SELECT default_character_set_name FROM information_schema.SCHEMATA S

WHERE schema_name = "[DB명]";

3) Table 확인

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 = "[DB명]"

  AND T.table_name = "[Table명]";

  

4) Column 확인

SELECT character_set_name FROM information_schema.`COLUMNS` C

WHERE table_schema = "[DB명]"

  AND table_name = "[Table명]";

  AND column_name = "[Column명]";

2. UTF-8로 변경

SET character_set_client = utf8;

SET character_set_results = utf8;

SET character_set_connection = utf8;

ALTER DATABASE [DB명] DEFAULT CHARACTER SET utf8;

ALTER TABLE [Table명] DEFAULT CHARACTER SET utf8;
