How Can I Efficiently Create a Temporary Table of Dates in SQL Server 2000?

Crafting a Temporary Table of Dates in SQL Server 2000

With the necessity to create a temporary table in SQL Server 2000, it becomes imperative to populate it with a range of dates and additional placeholder values. The original approach, utilizing a user-defined function, while promising, resulted in potential data gaps due to missing insert dates.

Moving forward, anticipate the need for a more comprehensive solution by incorporating the declaration of start and end dates:

declare $startDate set $startDate = select min(InsertDate) from customer
declare $endDate set $endDate = select max(InsertDate) from customer

To generate the desired temporary table, leverage the following approach:

DECLARE @dIncr DATE = $startDate
DECLARE @dEnd DATE = $endDate

WHILE ( @dIncr <= @dEnd )
BEGIN
  INSERT INTO #dates (Month) VALUES( @dIncr )
  SELECT @dIncr = DATEADD(MONTH, 1, @dIncr )
END

By iterating through the specified date range, this approach ensures a continuous set of dates, eliminating gaps and fulfilling the requirement for a complete and comprehensive table.
