SQL Server WHERE Clause using Temporary Columns
- by AbeP
Hi all,
I have the following query, which uses a CASE statement.
Is there anyway to add into the where clause WHERE IsBusinessDayFinal = 0? without using a temporary table?
thanks so much!
SELECT
ac.DateTimeValue,
CASE
WHEN pc.IsBusinessDay IS NOT NULL THEN pc.IsBusinessDay
ELSE ac.IsBusinessDay
END AS IsBusinessDayFinal,
ac.FullYear,
ac.MonthValue,
ac.DayOfMonth,
ac.DayOfWeek,
ac.Week
FROM
[dbo].[AdminCalendar] ac LEFT JOIN
[dbo].ProjectCalendar pc ON ac.DateTimeValue = pc.DateTimeValue AND pc.ProjectId = @projectId
WHERE ac.DateTimeValue >= @startDate AND ac.DateTimeValue <= @finishDate;
