Hello,

select column1,column2,column3,count(*) from table
group by column1,column2,column3 having count(*) > 1;

>> 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

"What if everyting around You isn't quite as it seems,
What if all the world You think You know is an inelaborate dream
When You look at Your reflection is that all you want it to be
What if You could look right through the cracks
Would You find Yourself...... Find Yourself afraid to see"
