How to Generate a Temporary Date Table with Placeholder Columns in SQL Server 2000?

Generating a Temporary Date-Filled Table in SQL Server 2000

To generate a temporary table containing a range of dates with additional placeholder columns, we can utilize a method similar to the one outlined in a previous question.

First, declare the start and end dates of the range:

DECLARE $startDate SET $startDate = SELECT MIN(InsertDate) FROM customer
DECLARE $endDate SET $endDate = SELECT MAX(InsertDate) FROM customer

Then, create a CTE (Common Table Expression) to generate a sequence of dates within the specified range:

WITH DateSequence AS (
    SELECT DATEADD(DAY, -1, @startDate) AS d
    UNION ALL
    SELECT DATEADD(DAY, 1, d)
    FROM DateSequence
    WHERE d < @endDate
)

Finally, use the CTE to create the temporary table and populate it with the placeholder columns:

SELECT d AS Month, 0 AS Trials, 0 AS Sales
INTO #dates
FROM DateSequence

This approach ensures that no gaps exist in the date range, even if there are no corresponding records in the customer table.
