When a database table grows in size to the hundreds of gigabytes or more, it can become more difficult to load new data, remove old data, and maintain indexes. Just the sheer size of the table causes such operations to take much longer. Even the data that must be loaded or removed can be very sizable, making INSERT and DELETE operations on the table impractical. The Microsoft SQL Server 2008 database software provides table partitioning to make such operations more manageable.
Partitioning a large table divides the table and its indexes into smaller partitions, so that maintenance operations can be applied on a partition-by-partition basis, rather than on the entire table. In addition, the SQL Server optimizer can direct properly filtered queries to appropriate partitions rather than the entire table.
This paper covers strategies and best practices for using partitioned tables and indexes in SQL Server 2008. It is intended for database architects, developers, and administrators of both data warehouse and OLTP systems, and the material is presented at an intermediate to advanced level.

I have a huge table with millions records and have problem for retrieve data from it.I Partitioned table by integer column and create a clustered index on this column on partition scheme and use it in my query but i have no change.please help me
How are you selecting data? Did you use any functions on the indexed column?
no,but i have to join my table to itself to select correct data . let me explain:
table Example:
OrderNumber OrderElement
1 0
1 1
1 2
2 0
3 0
3 1
I don’t want to see fourth record in my select. so i wrote:
select * from Example as E inner join Example az E_elemnt on
E.ordernumber = E_element.ordernumber and
E_element.orderelement > 0
