Re: List of SQL Statements run on system by time and date

Well, thanks for taking the trouble; I confess to avoiding the Information
Centre as I find the drilling up and down the links makes it hard for me to
retain details; I prefer to read an actual document.

Hi Rob

I'm sensing (maybe) a tiny bit of sarcasm here which is fine as I love
sarcasm; if that was not intended then please accept my apologies :)

Out of interest, have you actually read the documentation provided by the
links you sent through ? Some of it's pretty superficial, and reads like
programmer comments that are just re-stating code.

Based on your reading of the docs are you able to tell me if the number of
times run in the statement summary is for the time period selected in the
cache snapshot or for the life of the query ?

Did you find anywhere it indicated you could get a list of statements for
a
time period.

Does the documentation on "Plan Cache Procedures" or "Utility

Procedures"

help?

Hi

I am doing some performance investigation and would like to retrieve a
list
of statements run by time and date in order to examine the statements

run

at particular times of the day when CPU spikes.

I don't have performance tools or job watcher installed on the system

but

I
could get this done if it is the solution to my question.

I do have collection services running and I have extracted SQL Cache
snapshots to review the statements for particular periods.

I have some questions about the SQL Cache, for instance, if I run a

cache

snapshot selecting statements that ran after a certain date or time, the
statistics for the statements included in that snapshot look to be for

the

lifetime of that statement rather than for the just the period included

in

the snapshot.

Is there a decent reference that anyone is aware of as to what is

included

in the Cache snapshot and how to interpret/query the contents ?
