Developer Version

I have been trying to determine why an stored proc that I wrote that makes a
single random selection from a list of about 3 million phone numbers works
slowly in a particular client's office when in use by multiple Clients.
During investigation I found that the IT entrepreneur who supplied and
installed my Client's software provided a Developer's edition of SLQ Server.
As it is illegal to use this Edition commercially, my Client will be
upgrading to an appropriate version before the app goes into commercial use.
Meanwhile I would like to know if the Developer's Edition includes a
concurrent workload governor like the the Personal Edition or any other kind
of governor that would result in performance degradation?Bruce Thomas wrote:

No. You can't use Developer Edition in a production environment. But for
testing it's fine. There is no workload governor. Same as enterprise
edition.

How are you performing a single random selection from a 3 million row
table? Are you scanning the entire table or using some other means?

www.quest.com|||Thanks for info about governor. I am going to re-write the application so
that it grabs 1000 rows (which is enough for a user for a day) and then uses
them from a disconnected dataset in the front end, synchronising back
periodically. The stored proc now picks 1000 rows in 3 secs as compared to
0.7 secs for 1 row. I'm just worried about what will happen if 30 users log
on at about the same time.
The selection of rows is not really random, just somewhat random. When the
rows are entered they are given an index ID which is the reverse of the last
6 digits of the phone number. The selection is as follows where SPID =Unique
Sales person ID and is varchar(4):-
UPDATE tbTelNums SET SPID=@.SPID WHERE TelNumID IN (SELECT TOP 1000 TelNumID
FROM tbTelNums WHERE SPID IS NULL ORDER BY CallCount, RevIndx). The proc
then returns details for the marked rows. When I was returning one row I
used output parameters but this will now be a select query such as SELECT *
FROM tbTelNums WHERE SPID=@.SPID.
I plan to use a separate stored proc for UPDATE to synchronise the dataset.
ADDing and DELETEing only take place in a separate Admin front end.
Please let me know if you feel the stored proc for selecting rows could be
improved.
