A date dimension for SQL Server

The most common table you will find in a data warehouse will be the date dimension. There is no "right" implementation beyond what the customer needs to solve their business problem. I'm posting a date dimension for SQL Server that I generally find useful as a starting point in the hopes that I quit losing it. Perhaps you'll find it useful or can use the approach to build one more tailored to your environment.

As the comments indicate, this will create: a DW schema, a table named DimDate and then populate the date dimension from 1900-01-01 to 2079-06-06 endpoints inclusive. I also patch in 9999-12-31 as a well known "unknown" date value. Sure, it's odd to have an incomplete year - this is your opportunity to tune the supplied code ;)

-- At the conclusion of this script, there will be
-- A schema named DW
-- A table named DW.DimDate
-- DW.DimDate will be populated with all the days between 1900-01-01 and 2079-06-06 (inclusive)
--   and the sentinel date of 9999-12-31

    SELECT * FROM sys.schemas AS S WHERE S.name = 'DW'

    EXECUTE('CREATE SCHEMA DW AUTHORIZATION dbo;');
END

    SELECT * FROM sys.schemas AS S INNER JOIN sys.tables AS T ON T.schema_id = S.schema_id
