Question

I have a SQL-Sever query that returns the Capacity available to a person on any particular day.
The result is returned against each assignment the person has planned on that particular day.

My problem is that it returns the total capacity for that day on each line of the query’s result.
So when you show all the results for one day for one person, in a linked pivot table in excel (for example), you get the number of records multiplied by the base capacity.

I have written another query that counts the number of assignments per day per person.

I would like to divide the Capacity from the first query, by the number of records returned by the second query, but don’t know how to join the queries together.

This is the query that returns the list of assignments by day with capacity:

SELECT 
  MSP_EpmAssignmentByDay.TimeByDay, 
  MSP_EpmAssignment.ResourceUID, 
  MSP_EpmAssignmentByDay.AssignmentActualWork, 
  MSP_EpmResourceByDay_UserView.Capacity
FROM 
  MSP_EpmAssignment MSP_EpmAssignment,      
  MSP_EpmAssignmentByDay MSP_EpmAssignmentByDay,
  MSP_EpmResourceByDay_UserView
  MSP_EpmResourceByDay_UserView
WHERE   
  MSP_EpmAssignmentByDay.AssignmentUID = MSP_EpmAssignment.AssignmentUID 
  AND MSP_EpmResourceByDay_UserView.TimeByDay = MSP_EpmAssignmentByDay.TimeByDay

This is the query that returns the number of assignments per day per person:

SELECT 
  count(TimeByDay) as DayCount 
FROM 
  MSP_EpmAssignmentByDay_UserView 
  LEFT JOIN MSP_EpmAssignment_UserView
  ON MSP_EpmAssignmentByDay_UserView.AssignmentUID =
     MSP_EpmAssignment_UserView.AssignmentUID
GROUP BY ResourceUID, TimeByDay 

Any help would be greatly appreciated.

Thanks

Assuming the only fields you need are those included in the query, try:

SELECT 
  MSP_EpmAssignmentByDay.TimeByDay, 
  MSP_EpmAssignment.ResourceUID, 
  SUM(MSP_EpmAssignmentByDay.AssignmentActualWork) TotalWork, 
  MAX(MSP_EpmResourceByDay_UserView.Capacity) Capacity
FROM 
  MSP_EpmAssignment,      
  MSP_EpmAssignmentByDay,
  MSP_EpmResourceByDay_UserView
WHERE   
  MSP_EpmAssignmentByDay.AssignmentUID = MSP_EpmAssignment.AssignmentUID 
  AND MSP_EpmResourceByDay_UserView.TimeByDay = MSP_EpmAssignmentByDay.TimeByDay
GROUP BY
  MSP_EpmAssignmentByDay.TimeByDay, 
  MSP_EpmAssignment.ResourceUID

Alternatively, try changing the summary operation on Capacity in the pivot table to be MAX instead of SUM.

EDIT: To include a count of records for the same ResourceUID and TimeByDay in the details, try:

SELECT 
  MSP_EpmAssignmentByDay.TimeByDay, 
  MSP_EpmAssignment.ResourceUID, 
  MSP_EpmAssignmentByDay.AssignmentActualWork, 
  MSP_EpmResourceByDay_UserView.Capacity,
  count(*) over (partition by MSP_EpmAssignmentByDay.TimeByDay,
                              MSP_EpmAssignment.ResourceUID) DayCount
FROM 
  MSP_EpmAssignment MSP_EpmAssignment,      
  MSP_EpmAssignmentByDay MSP_EpmAssignmentByDay,
  MSP_EpmResourceByDay_UserView
  MSP_EpmResourceByDay_UserView
WHERE   
  MSP_EpmAssignmentByDay.AssignmentUID = MSP_EpmAssignment.AssignmentUID 
  AND MSP_EpmResourceByDay_UserView.TimeByDay = MSP_EpmAssignmentByDay.TimeByDay
