I have output from a select like this:
04:47:37> select * from attributes left outer join trailer_attributes on attributes.id = trailer_attributes.attribute_id;
+----+--------------+----------+-----------+------------+--------------+-----------------+
| id | name | datatype | list_page | trailer_id | attribute_id | attribute_value |
+----+--------------+----------+-----------+------------+--------------+-----------------+
| 1 | Make | text | 1 | 1 | 1 | Apple |
| 1 | Make | text | 1 | 2 | 1 | sdfg |
| 2 | Year | number | 1 | 1 | 2 | 2009 |
| 2 | Year | number | 1 | 2 | 2 | sdfg |

+----+--------------+----------+-----------+------------+--------------+-----------------+
I want to convert it to something more along the lines of:
id, Make, Year, Type, Axles, Size, Frame (etc)
1, Apple, 2009, iPhone, .....
2, sdfg, sdfg, sdfg, .....
Any suggestions?
