This is the query which takes about 32 seconds to execute. Any help will be appreciated.
Checked the index on **ID which is only 10% fragmented. No blocking issues.
SELECT fct.AccountID, count(*)
FROM fctAssetFulfillment fct
JOIN FulfillmentPartnerInstall fpi ON fpi.FMProBoxID = fct.AMC_BoxID
WHERE fct.Source = 'FMPro' AND isnumeric(fct.AMC_BoxID)<>0
AND fct.SerialNo = fpi.SerialTag
AND fpi.CompletionDate IS NOT NULL
AND fpi.AssetUsage LIKE '%install%'
AND fct.InstallActualDate<>fpi.CompletionDate
--AND (fct.FulfillmentStatus <> 'installed')
GROUP BY fct.AccountID

He who learns only to accumulate wealth, dies an atheist. And he who learns for the sake of action, dies a mystic."[/i]

Can you attach the actual execution plan please, saved as a .sqlplan file? Thanks.

for this query, i think we'd need to see the actual execution plan on this, as well as a list of all indexes on the fctAssetFulfillment and the FulfillmentPartnerInstall tables.

can you post that here as a .sqlplan attachment?

one problem is this portion of the WHERE statement:

AND fpi.AssetUsage LIKE '%install%'

'that's going to require a scan of the table; is there another way to filter the data to get the same rows? a status which coincides with that, maybe?

Does this help?

No, they're just pictures. It's like asking for a car and being given a picture. Execution Plans are active - hover over objects to view properties etc.

Right-click on the execution plan (actual, not estimated) and select "save execution plan as..."

not really;

the actual SQL plan allows us to review deep details of the plan, and tell if stats are out of date, which columns were used, which indexes, and so much more;

a picture of it's not enough.

I did save the plan but I don't know how to copy it on my local machine.
