너무 궁금해서 아무리 찾아도 저와 비슷한 질문을 한 사람이 없더군요. like 검색시에 대소문자를 구분해서 검색하는 방법이 뭐가 있을까 생각하다가... 예를들어, name 컬럼에 abc 라는 값이 들어있고, select * from table where name like '%Bc%' 이렇게 해도 검색이 되더라 이겁니다. 물론 필드형을 바꾸어 주거나 하는 방법이 있지만.... select * from table where binary(name) like '%Bc%' 이렇게 하면 대소문자를 구분하여 검색이 안되고, select * from table where binary(name) like '%bc%' 이렇게 해야만 검색

To make this search case sensitive, make sure that one of the operands has a case sensitive or binary collation. For example, if you are comparing a column and a string that both have the latin1 character set, you can use the COLLATE operator to cause either operand to have the latin1_general_cs or latin1_bin collation:
col_name COLLATE latin1_general_cs LIKE 'a%'
col_name LIKE 'a%' COLLATE latin1_general_cs
col_name COLLATE latin1_bin LIKE 'a%'
col_name LIKE 'a%' COLLATE latin1_bin
