Hello,

As Jay wrote your query should look like this:
select column1,column2,column3,count(*) from table
 group by column1,column2,column3 having count(*) > 1;

2010/12/21 Jayadevan M <Jayadevan.Maymala@ibsplc.com>:
>>                 select column1,column2,column3,count() from table
>> group by column1,column2,column3 having count() > 1;
>>
>>         This however gives me the following error:
>>
>>                 ERROR: count(*) must be used to call a parameterless
>> aggregate function
>
> Shouldn't it be count(*)?
> select column1,column2,column3,count(*).......having count(*) > 1
