Question

Good morning, mysql query which displays cases that have a date field completed & a total row amount, I want calculate this against the total cases but unsure if I can do all this inside one query. For example the current query outputs

Aug Sep Nov Total
10  20  20  50

The code for that being

     SELECT * from(
     Select Count(b.CaseID) As TotDB 
     from tblcontacts a 
     Inner Join  tblcases b 
     On a.ContactID = b.ContactAssignedTo)a
CROSS JOIN
    (Select
  Sum(Month(b.StatusSubmittedDate) = 8) As Aug,
  Sum(Month(b.StatusSubmittedDate) = 9) As Sep,
  Sum(Month(b.StatusSubmittedDate) = 10) As Oct,
  Count(b.CaseID) As Total,
  ROUND (100*Count(b.CaseID)/Count(b.CaseID),2) As Conversion
From
  tblcontacts a Inner Join
  tblcases b On a.ContactID = b.ContactAssignedTo
Where
  b.StatusSubmittedDate > '2012 - 01 - 01'
Group By
  a.ContactFullName With Rollup
Having
  Sum(b.CaseCommission) > 0.01)b 

What I need to it output is the below so I added the TotDB line above to see if that would help, it didn’t. What I need to find out is can I have a column in this query that bypasses the where/having clause to display all records

Aug Sep Nov Tot TotDB %Converted
10  20  20  50  100   50%

Thanks

probably you should do like this:

select Aug,Sep, Nov, Tot,TotDB,(Tot/TotDB*1.0)*100 as '%Converted' 
 from 
(SELECT * from(
     Select Count(b.CaseDate) As TotDB 
     from tblcontacts a 
     Inner Join  tblcases b 
     On a.ContactID = b.ContactAssignedTo)a
CROSS JOIN
    (select  
      Sum(Month(b.StatusSubmittedDate) = 9) As Sep,
      Sum(Month(b.StatusSubmittedDate) = 10) As Oct,
      Sum(Month(b.StatusSubmittedDate) = 11) As Nov,
      Count(b.CaseID) As Total,
    From tblcontacts a 
    Inner Join tblcases b 
    On a.ContactID = b.ContactAssignedTo
    Where
      b.StatusSubmittedDate > '2012-01-01'
    Group By
      a.ContactFullName With Rollup
    Having
      Sum(b.CaseCommission) > 0.01)b)c
