Detailed SQL Server Partition Script
I've been working with data warehouses again recently and needed to help out the rest of the team who were not familiar with partitioning in SQL Server. It's one of those subjects that really requires hands on experience with to truly appreciate the mechanics of partitioning, and for me it especially helps if I can visualize a concept.
I've always thought that the best way to explain partitioning as imagining that any one table in SQL Server has a partition count of exactly one. When we actually partition the table on a range value on a column then we introduce multiple copies of that table, and that it is the meta data that is replicated for the table. And it is from this copying of the table behind the scenes that helps with archiving and query performance. This is probably not far off from how partitioning actually works.
