Pardon me, too early & not enough coffee, that's not quite the 'max-concat trick', but it oughtta work.

Right. The 'max-concat trick', 'Group column statistics in rows', might be easier, eg...
SELECT 
  name,
  MAX( IF(question=100,answer,'') ) AS Ans100, 
  MAX( IF(question=101,answer,'') ) AS Ans101, 
  MAX( IF(question=102,answer,'') ) AS Ans102, 
  MAX( IF(question=103,answer,'') ) AS Ans103, 
  MAX( IF(question=104,answer,'') ) AS And104
FROM tbl 
GROUP BY name

stuck in modifying to get the result for the five questions (100 to
104). 

mysql> select * from test;
+-------+-------------+--------+
| name  | question_id | answer |
+-------+-------------+--------+
| Mark  | 100         | Yes    |
| Mark  | 101         | No     |
| Mark  | 102         | Yes    |
| Mark  | 103         | No     |
| Mark  | 104         | Yes    |
| Leigh | 101         | No     |
| Leigh | 102         | Yes    |
| Leigh | 103         | No     |
| Leigh | 104         | Yes    |
| Leigh | 100         | Yes    |
+-------+-------------+--------+
10 rows in set (0.00 sec)

Adapting the query for my table like so:

select 
t1.name,
answer as '100',
t2.101 
from test as t1 
inner join (
select name,answer as '101' from test where question_id='101'
) 
as t2 on t1.name=t2.name and t1.question_id='100';

+-------+------+------+
| name  | 100  | 101  |
+-------+------+------+
| Mark  | Yes  | No   |
| Leigh | Yes  | No   |
+-------+------+------+
2 rows in set (0.00 sec)

Any clues to get the other questions and their answers into the table
greatly appreciated.


cheers

Subject: Re: Returning results as a field name

  
I have a simple table that outputs results like so:
select name, question_id, answer from table;
     +-------+--------------+---------+
     |NAME   |QUESTION_ID   |ANSWER   |
     +-------+--------------+---------+
     |Mark	  |100	     |Yes	   |	
     |Mark	  |101	     |No	   |
     |Leigh  |100	     |Yes      |	
     |Leigh  |101	     |No	   |
     +-------+--------------+---------+	
Is there a way to query things so the result looks like this:
     select ???
     +--------+-----------+-----------+
     |NAME    |100        |101        |
     +--------+-----------+-----------+
     |Mark	   |Yes	   |No         |
     |Leigh   |No	   |Yes	   |	
     +--------+-----------+-----------+
