Hey guys I can't get this view to be faster. It is causing me serious problems. I am trying to get all this data gathered to return to the client but I can't make it any faster. My Low return time is 24 seconds and my High return time is 77 Seconds. But the it will take 24 Seconds even if no data is returned.
What can i do?
I have indexed every foreign key.
i have pictures of my execution path that you can look at at the following address

If you need anything to help me let me know I am more than willing to help to get this thing going faster..
The Main view is below

Hmm... Three table scans (at 25% of the execution plan each) seem to indicate you're missing appropriate indexes somewhere.|||Ok but where?
|||
You have a lot of joins in your query. Have you tried using temporary tables instead to store intermediate results and then join them ?
|||
Well, two of them are on the tbClient with CancelationDate and ClientStatusID, and one of those also looks at Contingency.
(Those are tables 2 and 3 with the 25% costs on the far right of the plan).
You're only indexing on ClientStatusID
You're also using a lot of functions in the filtering which will pop the plan back to table scans.
You may want to develop and "grow" this incrementally. Just do the first two tables and get them honed in, then add in the next table.
Get a good clean manageable baseline to grow from.
|||Also, to go along with Dale, you'll want to create indexes based on the composite key of the join. Don't just create an index for each column individually. Do as he says and "grow" the view. Each time you add something new, review the execution plan again to ensure nothing has snuck up on you.|||
These are all great ideas...
Thanks
|||How do i get rid of a hash match left?
