How to query???

[Arthur Radulescu]

Can anyone help me with this query???

I have a very big table (70.000 rows) which has several rows like this:

id        product        description

1        P1                desc1
2        P1                desc2

and I want to transform it into:

id        product        description

1        P1                desc1 desc2

I now how to do it in PHP but, is there anyway to do it with a SQL query???
