Hi

I'm trying to query the following tables to find out the Resource Companyname and Project Title for any Recruiters who have worked on more than/less than 6 projects within a specified period.

These are the tables:

dbo.tblResources
ResourceID
Company Name

dbo.tblRecruiters
RecruiterID
ResourceID

dbo.tblProjects
ProjectID
Datecreated

dbo.tblProfiles
ProfileID
ProjectID
RecruiterID

Basically I need to locate on the Profiles table where a recruiterID occurs 6 or more times - but it often occurs more than once per ProjectID. And I have to be able to query within specified time periods eg - today and 6 months ago.

Below is the table code and insert data:

Use DISTINCT to eliminate double row in Pf.RecruiterID, Pf.ProjectID. Then count the ProjectID
The query may be looks like below:

declare @StartDate smalldatetime,
	@EndDate smalldatetime

select	@StartDate = '2010/01/01',
	@EndDate = '2010/12/31'

select	RecruiterID, count(*)
  from (select	distinct Pf.RecruiterID, Pf.ProjectID
	  from	tblProfiles Pf inner join tblProjects Pr on
		Pf.ProjectID = Pr.ProjectID
	  where Pr.DateCreated >= @Startdate and 
		Pr.DateCreated < @EndDate + 1
	) X
  group by RecruiterID
  having count(*) >= 6

That query isn't recognising that a recruiterID can occur multiple times against any projectID, but with a different respondentID.

This is the query I have so far but the date part isn't working for me - its returning results outside of the 6 month window specified. If I remove that clause it still returns the same results.

select distinct r.CompanyName, p.projectID, p.Title, p.datecreated
from tblResources r
join tblRecruiters rc on rc.ResourceID = r.ResourceID
join tblProfiles pr on pr.recruiterID = rc.recruiterID
join tblProjects p on p.ProjectID = pr.projectID
where rc.recruiterid in
(select pr.recruiterid
from tblProfiles pr
join tblProjects p on p.projectID = pr.projectid
where p.datecreated >= DATEADD (mm,-6,getdate())
group by pr.recruiterid
having count(distinct pr.projectid)>= 6
)
order by r.companyName, p.projectID
go
