Hi Experts,

Does anybody know how to make the (Executed)  Execution Plan output from OSQL, just like it does from within Query Analyser ? (Possibly via a SET Command ? the SHOWPLAN options/are not suitable as this does not actually execute the statement and generates inconsistencies between the run / estimated run plans..)


Regards,

Dan.

May not be as easy as you want it to be, but take a look at DBCC TRACEON using traceflag 310 or 317 in combination with trace flag 3604  You can tell it to log the plan that was actually used to a file.  This  is actually pretty cool because it gives TONS more information than a QA plan does.

Looks like the above flags were holdovers from sybase--this is actually pretty interesting:

Just to clarify -- I'm using SQL Server 2000 & 7.  (Might need one version for each system, I understand that they do not always run the same on both systems.)

Its not getting any results back under sql-server 2000 (using QA) with these options at all ...
(This is more of a 6.5 option ?)

Ok, I don't have a 7.0 server here to test with, but I think this works on both (I can test tomorrow).  This returns the actualy query plan used:

set statistics profile on

@arbert -- now you know that old question where a user was requesing what indexes are used on sps/views.. (cached execution plan...) instead of using sql-server profiler wouldnt' it be better to use this 'set statistics profile on' as it lists the indexes used (as long as you can generate a test work-load for every sp)... points are yours' arbert.  
This works and does the trick for me on my sql 2000 box...

Ya, I understand.  The whole "estimated" and "actual" plan is kind of a pain.  Especially if your talking para plans when it depends on the actual workload on the box too--sometimes it might run para, sometimes not.
