Question

I am using durpal 6. while retrieving data i got the following output:

| nid | fid |
------------
| 10 | 49 |
| 10 | 57 |
| 10 | 76 |
| 14 | 34 |
| 14 | 45 |
| 14 | 95 |
| 18 | 57 |
| 18 | 65 |
| 18 | 75 |
| 19 | 56 |
| 19 | 45 |
| 19 | 75 |

Now i want to refine the above output like this

| nid | fid1 | fid2 | fid3 |
----------------------------
10    | 49   |  57  |  76  |
14    | 34   |  45  |  95  |
18    | 57   |  65  |  75  |
19    | 56   |  45  |  75  |

Please suggest sql query for that..

Answer 1

You should better explain what you are trying to do. You can use GROUP_CONCAT() to return the fids as a comma separated list.

SELECT nid, GROUP_CONCAT(fid)
FROM tbl
GROUP BY nid
