SQL Server JDBC Deriver Problems
If the SQL data type is 'timestamp', we need to use ResultSet.getBytes() to retrieve its value. If the SQL data type is 'datetime', we can use ResultSet.getTimestamp(). It is said timestamp is interanlly saved as binary data.
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection conn = DriverManager.getConnection
("jdbc:sqlserver://<url_address>;user=<user>;password=<password>;database=<database>");
Statement statement = conn.createStatement
(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
ResultSet rs = statement.executeQuery("...");
while (rs.next()) {
System.out.println(rs.getTimestamp(1));
}
} catch (Exception e) {
e.printStackTrace();
}
