Name and version of the database you are using: postgres 8

So know with this i think that all information are in the message.
Could you tell me why the concat (||) is not permitted in having count instruction ?

Thanks in advance

Thanks in advance.

I do believe it doesn't recognize it at all. What are you trying to do? What does your query have to do?

i have a table (MyObject) that contains two fields (field1 and field2).
I would like to get a list of information of the couple fields who is in the table more than once.

--------------
| MyObject |
--------------
| field1 |
| field2 |
--------------

Rows
----------------------
| field1 | field2 |
----------------------
| 1 | 1 |
----------------------
| 1 | 0 |
----------------------
| 0 | 1 |
----------------------
| 1 | 1 |
----------------------
| 0 | 0 |
----------------------
| 0 | 1 |
----------------------

With the request i should have this list :
----------------------
| field1 | field2 |
----------------------
| 1 | 1 |
----------------------
| 0 | 1 |
----------------------

Witch represent the couple of fields witch are more than one in the table.
I hope that is more clear.

Denez

Do you only need the values or instances of MyObject. If you only need the values then you would do a simple group by:
