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.
