Hello:

I think your syntax for the SQL statement string is the problem.  It 
should read:

ResultSet myResult = stmt.executeQuery("Select * from logKilang where 
idKlg = " + id);

If 'id' is an integer.  If 'id' is a string it should read:

ResultSet myResult = stmt.executeQuery("Select * from logKilang where 
idKlg = '" + id + "'");

String values need to be single quoted in SQL.  Also, you do not put a 
semicolon at the end of SQL statements.
