Question

Think my problem is I am trying to sum a count in the same query, could this be achieved in php to avoid this? The Records column displays count of records while the Costs sums the costs, this works great but I would like to then peform a sum of both these columns to show a grand total?

Select
  tblcontacts.ContactFullName As Name,
  Count(tblcases.CaseID)As Records,
  Sum(tblcases.CaseCommission) As Costs
From
  tblcontacts Inner Join
  tblcases On tblcontacts.ContactID =
    tblcases.ContactAssignedTo
Group By
  tblcontacts.ContactFullName

Answer 1

Use With RollUp at last. Single time scanning of table, so it’s performance oriented.

Select
  tblcontacts.ContactFullName As Name,
  Count(tblcases.CaseID)As Records,
  Sum(tblcases.CaseCommission) As Costs
From
  tblcontacts Inner Join
  tblcases On tblcontacts.ContactID =
    tblcases.ContactAssignedTo
Group By
  tblcontacts.ContactFullName
WITH RollUP
