i wasnt aware that you could create a PK that wasnt clustered, i thought they were all clustered indexes.

In SQL Server they are clustered as default. But you can make then non-clustered and use the clustered index for yourself.

As I'm sure you know - it depends on your database design and how you access the tables.
I think they are made this way by default to ensure at least some "workable" indexes for default databases from people who haven't looked too much into indexation.
Because if you mainly access a table via - for example - foreign keys and extract 2 or 3 specific rows of data, it makes sense - to me at least  - to make that your clustered index.
Also if your PK is primarily an identity or similar number which mattes little then I would also say it makes sense to keep that index non-clustered, because it usually means you'll access data not in the index anyway and the benefits of the clustered index diminishes.
However if your primary key consists of "relevant data" and you need to access this data only - and often - then it is beneficial to have it as clustered.
In my opinion - it is as all things with databases, a case-by-case evaluation, but as mention first - my main guess is that it is made to simply have some "default" clustered indexes for the default databases, and those who know what they are doing will evaluate whether it is a beneficial index and change it if not anyway.

One instance I have seen is when using a GUID as a PK field.

use UNION
select convert(varchar(10),status.Logintime ,101) as Date,empcode,empname,count(*) as [No of Calls]<br />
from status join empmaster on empmaster.empid = status.empcode<br />
where empmaster.Permission <> '1' and logintime between '06/02/2006' and '06/03/2006' <br />
group by empcode,empname, convert(varchar(10),status.Logintime ,101) order by empcode asc<br />
<br />

<br />

where empmaster.Permission <> '1' and logintime between '06/02/2008' and '06/03/2008' and<br />

Use "Union All" instead of "Union" if your 2 queries doesn't return duplicates.

Yes you are right, I forgot to write UNION ALL in both two places on my first response.Thanks for correcting me dude.

Hi guys,
I have the following query, example
Select a.id, b.description
from table1 a
left join (select top 1 c.id, c.description from tableb c where c.id = a.id) as b on b.id = a.id
The reason I do this is because tableb could have multiple duplicates of c.id and I want it to only do the select on one specific id from the table1.
But I get the error because a.id is not within the select statement of tableb.
Is there any way that I can do this, if I remove the where clause in the tableb select statement it returns duplicate values on the description.
Thanks in advance

Try this
Select a.id<br />
(select top 1 c.id from tableb c where c.id = a.id) ,<br />
(select top 1 c.description from tableb c where c.id = a.id) <br />
from table1 a

ChandraRam is correct, but you can use this query too:
select top 1 id from tablename where id < 5 order by id desc
