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.
