I can't get the next record when i use t开发者_如何学Pythonhis code .. it only shows the first record.

try using

while(rs.next())
{
    int id_col = rs.getInt("ID");

    String id = Integer.toString(id_col);

    String first = rs.getString("First_Name");

    String last = rs.getString("Last_Name");

    String job = rs.getString("Job_Title");

    ......
}

Hope this helps.

Assuming you want to loop through and show them all one by one, you'll need to use a loop.

You're using an if statement on the next method, which will only get the next one and then stop. If you want to get each of them you need to do a loop.
