SQL join conditional either or not both?
I have 3 tables that I'm joining and 2 variables that I'm using in one of the joins. What I'm trying to do is figure out how to join based on either of the statements but not both. Here's the current query: SELECT DISTINCT WR.Id, CAL.Id as 'CalendarId', T.[First Of Month], T.[Last of Month], WR.Supervisor, WR.cd_Manager as [Manager], --Added to search by the Manager-- WR.[Shift] as 'ShiftId' INTO #Workers FROM #T T --Calendar RIGHT JOIN [dbo].[Calendar] CAL ON CAL.StartDate <= T.[Last of Month] AND CAL.EndDate >= T.[First of Month] --Workers --This is the problem join RIGHT JOIN [dbo].[Worker_Filtered]WR ON WR.Supervisor IN (SELECT Id FROM [dbo].[User] WHERE FullName IN(#Supervisors)) or (WR.Supervisor IN (SELECT Id FROM [dbo].[User] WHERE FullName IN(#Supervisors)) AND WR.cd_Manager IN(SELECT Id FROM [dbo].[User] WHERE FullNameIN(#Manager))) --Added to search by the Manager-- AND WR.[Type] = '333E7907-EB80-4021-8CDB-5380F0EC89FF' --internal WHERE CAL.Id = WR.Calendar AND WR.[Shift] IS NOT NULL What I want to do is either have the result based on the Worker_Filtered table matching the #Supervisor or (but not both) have it matching both the #Supervisor and #Manager. The way it is now if it matches either condition it will be returned. This should be limiting the returned results to Workers that have both the Supervisor and Manager which would be a smaller data set than if they only match the Supervisor. UPDATE The query that I have above is part of a greater whole that pulls data for a supervisor's workers. I want to also limit it to managers that are under a particular supervisor. For example, if #Supervisor = John Doe and #Manager = Jane Doe and John has 9 workers 8 of which are under Jane's management then I would expect the end result to show that there are only 8 workers for each month. With the current query, it is still showing all 9 for each month. If I change part of the RIGHT JOIN to: WR.Supervisor IN (SELECT Id FROM [dbo].[User] WHERE FullName IN (#Supervisors)) AND WR.cd_Manager IN(SELECT Id FROM [dbo].[User] WHERE FullName IN(#Manager)) Then it just returns 12 rows of NULL.
