Hi All,

I have a query that returns everyone who has completed a variety of courses.  Five of these courses are part of a specific curriculum. I'm trying to return ONLY the people who have completed ALL five courses and then count them.

Have a great day!

Here's the query.  It returns a count of anyone who has completed any of the five courses grouped by Instructor.  I need it to only count the people who have completed ALL five courses.
SELECT dbo.Inst.Inst_No,dbo.Inst.Inst_FName, dbo.Inst.Inst_LName,
       SUM(CASE WHEN TBL_TMX_Attempt.AttndStatusFK=1 then 1 else 0 end) AS Completions
FROM  dbo.Org INNER JOIN
               dbo.tblEmpOrg ON dbo.Org.Org_PK = dbo.tblEmpOrg.EmpOrg_OrgFK RIGHT OUTER JOIN
               dbo.Inst INNER JOIN
               dbo.TBL_TMX_ActInst ON dbo.Inst.Inst_PK = dbo.TBL_TMX_ActInst.InstFK INNER JOIN
               dbo.TBL_TMX_Activity AS TBL_TMX_Activity_1 INNER JOIN
               dbo.TBL_TMX_Attempt AS TBL_TMX_Attempt_1 ON TBL_TMX_Activity_1.Activity_PK = TBL_TMX_Attempt_1.ActivityFK ON 
               dbo.TBL_TMX_ActInst.ActivityFK = TBL_TMX_Activity_1.Activity_PK RIGHT OUTER JOIN

GROUP BY Inst_No,dbo.Inst.Inst_FName, dbo.Inst.Inst_LName

yes please post the query
but it sounds like just a sum(count)

What is the structure of the table that contains the employees and the courses they have taken?  Does that table indicate course dates and whether they passed the course or not?  Are instructors of any interest, if not, I'd leave them out of the mix.

Generally, with an EmployeeCourses table that contains EmpID, CourseID, CourseDate, CourseStatus, I would write something like

SELECT CoursesPassed.EmpID
FROM (
SELECT DISTINCT EmpID, CourseID
FROM EmployeeCourses
WHERE CourseID IN (1, 2, 3, 4, 5)
AND CourseStatus = 'Pass') as CoursesPassed
GROUP BY EmpID
HAVING Count(CoursesPassed.CourseID) = 5

The TBL_TMX_ATTEMPT table has UserID, ActivityID, StartDate, EndDate, and CompletionStatus.  I need the instructors because I'm trying to see how many people each instructor has taught the curriculum to.  The instructors are pulled in from the TBL_TMX_ActInst and Inst tables.

My result should look something like this:

InstFName  InstLname  Completions
John             Doe             7  (means 7 people completed all five courses with this inst).
Jane             Doe             2
Frank           Smith          4

So the people have to have had the same instructor for all 5 courses?

If not, say they had 1 course each from 5 different instructors -- does each instructor get to count that as 1 or 0.2?

Author

Commented:
Good question.  Each instructor would count it as .2.

I'm having trouble working thru the table relationships, given the way the joins are written/structured.

What you need to do is first, in a separate subquery (easiest), just get the students who have passed all five courses.  Then join that to the other tables to get your totals.  I tried to write that up but the table relationships in the original query aren't clear to me.

So, the base query, which identifies all of those individuals who took all five courses might look something like above.   You would then have to join that back to your EmployeeCourses table, and probably your instructors table

SELECT I.InstFName, I.InstLName, Sum(.2) as Completions
FROM (
             SELECT CoursesPassed.EmpID
             FROM (
             SELECT DISTINCT EmpID, CourseID
             FROM EmployeeCourses
             WHERE CourseID IN (1, 2, 3, 4, 5)
             AND CourseStatus = 'Pass') as CoursesPassed
             GROUP BY EmpID
             HAVING Count(CoursesPassed.CourseID) = 5
             ) as Passed5
INNER JOIN EmployeeCourses as EC
ON Passed5.EmpID = EC.EmpID
INNER JOIN Instructors as I
ON EC.InstructorID = I.InstructorID
WHERE EC.CourseID IN (1,2, 3,4,5)
GROUP BY I.InstFName, I.InstLName

Scott,

LOL,

I gave up on the OP's original query for the same reason you did.  I just wrote my query based on how I might have constructed my tables.  Seems the OP was able to figure that out.

Dale - yes, I was able to adapt your query to make it work.

Scott - Lol!
