Query to do an additional Count

Question

Me again....

I'm writing a query which will total the COUNT returned in the subquery alias b. But I need to add another subquery which will COUNT based on lets say an alias c.

Here is what I have:

SELECT b.Employee , b.[Time In], b.[Time Out], COUNT(b.empnid) AS Orders
FROM (
         SELECT E.FIRSTNAME + ' ' + E.LASTNAME  AS Employee
                 , right('0' + ltrim(right(convert(varchar,  MIN(cast(LogInTime as time)), 100), 7)), 7)  AS [Time In]
                 , right('0' + ltrim(right(convert(varchar,  MAX(cast(LogOutTime as time)), 100), 7)), 7)  AS [Time Out]
                 , o.TicketNumber , o.ToCusNid , e.EmpNid 
         FROM DBO.SESSIONS AS S
              JOIN DBO.EMPLOYEES AS E ON E.EMPNID = S.EMPNID
              JOIN Orders AS O ON o.SlsEmpNid = e.EmpNid 
         WHERE CONVERT(DATE, S.LOGINTIME, 102) = '2011-03-08'  
                 AND CONVERT(date, o.OrderedDate, 102) = '2011-03-08'
         GROUP BY E.FirstName, e.LastName , o.TicketNumber , o.ToCusNid, e.EmpNid 
       ) b
GROUP BY b.Employee, b.[Time In], b.[Time Out]

I would like to add as a subquery alias C

SELECT * FROM CustomerVisits 
WHERE CONVERT(DATE, VisitTime, 102) = '2011-03-08'

And have a COUNT(c.cusnid) or something like that to give me an additional column count on the main select. I was trying to join alias C on employeeid but this was not working. the ORDERS count would increase and become incorrect.

Any suggestions how I can add an additional count to a subquery or how I should go about writing this?

Answer 1

I stepped away from this and came back with a cleared head. I was able to add the alias C and join on empnid and visitedbynid and pull count through the alias subquery for c. This is taken care of. Thanks again.

SELECT 
  b.Employee , b.[Time In], b.[Time Out], COUNT(*) AS Orders, c.NONSERVICE 
FROM (
            SELECT E.FIRSTNAME + ' ' + E.LASTNAME  AS Employee
                        , right('0' + ltrim(right(convert(varchar,  MIN(cast(LogInTime as time)), 100), 7)), 7)  AS [Time In]
                        , right('0' + ltrim(right(convert(varchar,  MAX(cast(LogOutTime as time)), 100), 7)), 7)  AS [Time Out]
                        , o.TicketNumber , o.ToCusNid , e.EmpNid 
            FROM DBO.SESSIONS AS S
                    JOIN DBO.EMPLOYEES AS E ON E.EMPNID = S.EMPNID
                    JOIN Orders AS O ON o.SlsEmpNid = e.EmpNid 
            WHERE CONVERT(DATE, S.LOGINTIME, 102) = '2011-03-08'  
                        AND CONVERT(date, o.OrderedDate, 102) = '2011-03-08'
                        AND e.RecName like '(SR%'
            GROUP BY E.FirstName, e.LastName , o.TicketNumber , o.ToCusNid, e.EmpNid 
        ) b       
 JOIN ( 
         SELECT visitedbynid, COUNT(*) AS NONSERVICE FROM CustomerVisits 
         WHERE CONVERT(DATE, VisitTime, 102) = '2011-03-08' 
         GROUP BY VisitedByNid
       ) c ON c.VisitedByNid = b.EmpNid 
GROUP BY b.Employee, b.[Time In], b.[Time Out], c.NONSERVICE

Answer 2

does this give you what you need:

SELECT 
  b.Employee , b.[Time In], b.[Time Out], COUNT(b.empnid) AS Orders,
  (SELECT COUNT(c.cusnid) FROM CustomerVisits 
     WHERE CONVERT(DATE, VisitTime, 102) = '2011-03-08') as AdditionalCount
FROM (
            SELECT E.FIRSTNAME + ' ' + E.LASTNAME  AS Employee
                        , right('0' + ltrim(right(convert(varchar,  MIN(cast(LogInTime as time)), 100), 7)), 7)  AS [Time In]
                        , right('0' + ltrim(right(convert(varchar,  MAX(cast(LogOutTime as time)), 100), 7)), 7)  AS [Time Out]
                        , o.TicketNumber , o.ToCusNid , e.EmpNid 
            FROM DBO.SESSIONS AS S
                    JOIN DBO.EMPLOYEES AS E ON E.EMPNID = S.EMPNID
                    JOIN Orders AS O ON o.SlsEmpNid = e.EmpNid 
            WHERE CONVERT(DATE, S.LOGINTIME, 102) = '2011-03-08'  
                        AND CONVERT(date, o.OrderedDate, 102) = '2011-03-08'
            GROUP BY E.FirstName, e.LastName , o.TicketNumber , o.ToCusNid, e.EmpNid 
        ) b
GROUP BY b.Employee, b.[Time In], b.[Time Out]
