Thanks I have checked it, I wanted to know How Can I Run SQL Tuning Advisor on the SQL statement with SQL_ID " XYZ " in EM ?The links provided to you will tell you how to do it, and the EM wizard is fairly self explanatory. I'm going to ask why you want to. You ran a report for 1/2 an hour on a system presumably with at least 2 CPUs (though you don't say) so that means you have most likely over an hours worth of CPU available to you. Your total database time is 6 minutes. That doesn't sound like a struggling database to me, does it to you? If you manage to save 66% of the time then you'll have saved 4 minutes. Is that a worthwhile goal.
However let's take a look at the most costly statement - the update - that consumes 112s or nearly 2 of your 6 minutes. However each execution only takes a twentieth of a second. Do your users notice that and want the update time to be (say) a fiftieth of a second instead? Where you might have an opportunity is in the fact that this statement is really quick, but is executed 2256 times in that half hour - that is 75 times a second. It's more than likely that this is a loop and that a more efficient way of doing this would be not to execute in the loop but execute a set based update. Unfortunately the SQL Tuning advisor isn't capable of making this sort of recommendation.
In total then it looks like you've only actually got 4 minutes of your half hour that the SQL Tuning Advisor is likely to be able to improve. The count(*) might be improvable - if say you haven't got an index on the send_unsend column and that column is selective - but you still have to ask is the potential improvement worth it.
