We implement partition table to improve performance. It is a feature in 2008/2005 and It is very easy to do.
1) create filegroups and database files for partitioning. This can be seen in the first portion of the above script.
2) Create a partition scheme and partition function. This can be seen in the second portion of the above script. Remember to use generic name if it is to be used by multiple tables.
3) create a table to use the partition scheme. This can be seen in the third portion of the above script.
4) once inserted all records, you can use the last query to see the partion being used by records.
For we have table used to be small but grown over a few million records now, I have to create a new partition table, move over all records. Remember the key column should be on the cluster index (the fastest).
Violla, we are ready. You can use the same partition scheme on another table.
