It takes over a minute for this query to return 1060 rows. Is there anything you can recommend that I can do to speed this up? By the way, just selecting from the invoice table is not enough. I need a complete list of customers and not all customers have been invoiced.
Select cust.name, inv.BalanceRemaining, inv.DueDate, inv.TxnDate, inv.IsPaid, cust.listId from customer cust
left outer join invoice inv on inv.customerRefListId = cust.ListId where cust.IsActive = 1
Thanks, Rob |

Sorry, your left outer join has to do a full table scan of the customer table and look up all the the invoices for each customer for every customer you have.
This is the fastest, but only shows Customers with outstanding balances:
sp_report CustomerBalanceSummary show Text, Label, Amount
parameters DateMacro = 'All' |
