Question

Answer 1

To get auto generated key we have method getGeneratedKeys method in preparestatement which return resultset that contain key value all we need is pass key column name to preparestatement

pstm = con.prepareStatement("insert query",new String[]{primarykeycolumnname});
int i = pstm.executeUpdate();
if (i > 0) 
{
    ResultSet rs = pstm.getGeneratedKeys();
    while(rs.next())
    {
        System.out.println(rs.getString(1)); 
    }
}
