Help needed in Table partition

Hi,
I'm doing horizontal partition with partition key as an
integer datatype.It's a part of primary key also.When i
search for a particular value, it's fetching correct
results ,but if we examine execution plan all the
partitions are searched for a particular search.
Please help me to fetch the correct result in execution
plan
Thanks in advance,
Sunish
is your primary key clustered? Are you saying the the execution plan does a
table scan?

|||hi,
yea, the primary key is a clustered one.When i checked
the execution p[lan it shows Clustered Index Scan for
each partition ......also instead of compute saclar it's
showing Concatenation ,Cost=2%.
Thanks in advance

Since it has to search for the corresponding partition
only rather than searching the entire partition views ,i
think i am wrong some where .
also in the execution plan ,it has to show compute scalar
instead of concatenation, as i referred to articles which
i collected from the net.
please inform if there is any other way i need to perform
this .
my query is like this only
select * from detailstable where programcode =222
