[MS-SQL] CONVERT 함수로 DATETIME 타입 변환

Published: by Creative Commons Licence

CONVERT( data_type [( length )] , expression [, style ])
SELECT
  GETDATE() AS ex1,
  CONVERT(VARCHAR, GETDATE(), 120) AS ex2
FROM dbo.bod_faq

ex1
-----------------------
2013-11-11 18:45:28.560

ex2
-----------------------
2013-11-11 18:45:28

왜 썼는지 기억 안나는 문단

org.apache.ibatis.session.SqlSession을 이용한 JDBC의 경우:

MS-SQL의 DATETIME은 java.sql.Timestamp 클래스 타입으로 반환한다. String으로 받고싶다면 CONVERT()를 통해 VARCHAR 타입으로 변환한다.
