User-Created GENERATE_SERIES() Function for Older SQL Server Versions

In the world of SQL Server, adaptation is key. While the built-in GENERATE_SERIES() function was a valuable addition in SQL Server 2022, its absence in older versions created a functionality gap. Enter the user-written GENERATE_SERIES function. Adapted from Jeff Moden's "dbo.fnTally", it offers an efficient means to generate a series of numbers within a defined range in older SQL Server versions. Its design mirrors the built-in function in SQL Server 2022, making the transition between versions as simple as removing the dbo. prefix. This forward-thinking design reflects the ingenuity of the SQL Server community, ensuring a seamless, efficient database migration experience.

A DateRange Table Valued function

The function is an inline table-valued function (or sometimes called a parameterised view) so it can be used just like a view or a table but needs parameters. It generates a single-column table of datetime2 with rows differing by any multiple of any of the dateparts that SQL Server provides.

Too Many Choices

I have a table, dbo.MasterBrands, with this data:

BrandID OfficialName
1       Samsung
2       Apple
3       Microsoft
4       Adidas
5       Coca-Cola
I run this query. What is returned for Coca-Cola?
SELECT CHOOSE(BrandID, 'Conglomerate', 'Tech and Design', 'Desktop', 'Apparel')
FROM dbo.MasterBrands;
