Oracle JDBC Timestamp test

Oracle JDBC,  날짜에 시간 포함하여 DB에 입출력하기

오라클의 DATE 형 컬럼에 java.sql.Date 형 오브젝트를 저장할 때

pstmt.setDate(1, hiredate);

오라클로부터 java.sql.Date 형으로 가져오기

java.sql.Date hiredate = rs.getDate("HIREDATE");

오라클의 DATE 형 컬럼에 날짜와 시분초까지 저장하고 가져오기( java.sql.Timestamp )

pstmt.setTimestamp(1, new java.sql.Timestamp( uDate.getTime() ) );

java.sql.Timestamp hiredate = rs.getTimestamp("HIREDATE");

	public boolean insertDate(){
		String sql = "INSERT INTO emp2 (empno, ename, hiredate) VALUES(?,?,?)";
		conn = getConn();
		try {
			pstmt = conn.prepareStatement(sql);
			pstmt.setInt(1, 1234);
			pstmt.setString(2, "김인철");
			SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
			java.sql.Timestamp hiredate = null;
			try {
				java.util.Date uDate = dateFormat.parse("2016-12-05 06:11:03");
				hiredate = new Timestamp(uDate.getTime());
			} catch (ParseException e) {
				e.printStackTrace();
			}
			pstmt.setTimestamp(3, hiredate);
			int n = pstmt.executeUpdate();
			return n>0 ? true : false;
		} catch (SQLException e) {
			e.printStackTrace();
		} finally{
			closeAll();
		}
		return false;
	}
