Accessing Estimated Query Execution Plan (QEP) statisitics

Hi,

I have a question about estimated query execution plans that are
generated in QA of MSSQL.

If I point at an icon/physical operator in the estimated QEP, it shows
me
some statistics about the operator.
Is there a way to retrieve these statistics through a query, i.e., can
these statistics be available to the user?

Also, is there a way to generate these statistics on my own?

thanks in advance

-TC.

Yes. It's all done through SQL statements. Rather than saying the exact
statements to use(*), I will tell you how find out: Use the SQL Server
Profiler to see what commands that Query Analyzer submits to SQL Server
when you have enabled these options.

(*) Since to tell which they are, *I* would have to run Profiler.
Also, is there a way to generate these statistics on my own?


I'm not sure that I understand the questions, but if I'm guessing right
the answer is: no, you can't.

TC,

See SET SHOWPLAN_ALL IN BOL for getting the data you're asking about. To
get the results of your query *and* the plan, see SET STATISTICS PROFILE.

Craig

P.S. Playing with these for a while will give you some real appreciation for
QA! :)

I came across a situation that I've been unable to explain and was hoping somebody had an answer: I had written an update query which was taking about 8 seconds to run and considered it too slow.

To make sure that I didn't miss anything, I copied the SQL statement back into a query and tried running it again. It now also only took 1...

Hi NG, does IBM Universal Database 8.2 make any difference between actual and estimated execution plans like in SQL Server ("set showplan_all on" for estimated execution plan and "set statistics profile on" for actual execution plan)? Does "explain plan selection for" generate the *estimated* execution plan? Didn't find any distinction of actual or estimated execution plans in the information center. Thanks for help,

I have a stored procedure that will execute with less than 1,000 reads one time (with a specified set of parameters), then with a different set of parameters the procedure executes with close to 500,000 reads (according to Profiler). In comparing the execution plans, they are the same, except for the actual and estimated number of rows. When the proc runs with parameters that produce reads that are less than 1,000 the actual and...

Hi, We are trying to solve a real puzzle. We have a stored procedure that exhibits *drastically* different execution times depending on how its executed. When run from QA, it can take as little as 3 seconds. When it is called from an Excel vba application, it can take up to 180 seconds. Although, at other times, it can take as little as 20 seconds from Excel.
