A Very Disturbing Finding about SQL Server Performance

After some testing, we have found that, when a client
computer is connected to an MS SQL server, and they are
listening to a music cd, in their own computer, the
performance of the SQL server degrades badly, until the
client stops listening to the CD. We have used
performance monitor to check this and are incredulous at
the findings. I have gone out on the web and, after some
exhaustive searching, have come up with nothing written
on the subject. Has anyone else experienced this
behavior? Has anyone else tested this? Does anyone have
an idea as to why this may be happening and how we can
insulate the performance of the SQL server from the
casual activities of the clients?
Thanks in advance for your replies.
John MangioneI listen to CDs as well as many of our developers while
connected to SQL server. We've never experienced what you
mention here.

implementing database access.
If its done through cursors or VB Recordsets, this could
well be the case.
A (I won't say better) perhaps more efficient way is to
use SET commands.
E.g.
Issue the command to UPDATE directly to the server, rather
than locking the cursor.
Microsoft do recognise this as being more efficient.
Good Luck.

Why, these 3D graphics can eat up between 30-50% of your CPU.
I do not have any idea about the spec's of the machine they are running on
but if it is a desktop with SQL running on it, it can slow them down
significantly
Hope this helps|||This problem may very well expose design flaws in your application.
Regardless of what a user does on his/her machine SQL server must never be
slown down. You do not open a cursor at the client side and keep it open for
a log time, actually you are better off if you never use client side
cursors.

a simple question on compatibility

Hello,

I was wondering if there is a version conflict with SSRS for SQL 2000 and Visual Studio 2005? When I went to install the client it was looking for visual studio 2003 and well, I don't have that. Asides from stating it during the install, the client appeared to fully install and of course when I opened VS, no option for SSRS.

I was installing the client over a WAN and figured I should ask before I go on a bug hunt for what I did wrong.

Thanks

VS 2005 will produce 2k5 reports which can′t be deployed on a SQL 2k RS.

A Simple Insert statement in European version of SQL

I have a client that uses my utility program to insert a record into a
table. Once my program receives the values, creates an insert statement
with comma separated values. Ie:
Insert into T (a,b) values (1.578, 2)
I now understand that those numeric values could have ',' in place of
decimal point for European version. So, the above values would look like
1,578 and 2.
How does the insert statement would know ',' is not a separator in this
case ? Ie:
Insert into T (a,b) values (1,578, 2) --> resulting
into syntax error
Should I be using a different value separator character ?
TIA.
MacI am not the one producing the values with ',' in place of decimal points.
It is SQL Server of European version that returns the data I am collecting
with embedded comma. So, when I submit a query of "Select a from T"
( a is defined to be a real type number), it returns 2,476 instead of
2.476. So, my question is how do I take these returned value with
embedded comma and insert them back into say another field in a table ? I
do not have such SQL version in my site to see what is going on and how to
accomplish such inserts.

VB does use the client-settings to format numbers, dates,...
You'll have to use a format function to convert to a propre string.
e.g. strsql = "insert into table1 (col1) values (" & Format(numcol,
"###0.00") & ")"

formats something that SQL Server outputs with a comma doesn't mean that SQL Server accepts that as
a valid input format.

I've checked my vb-code again, and found this extra.
'Aparently the format still uses the client-setting for decimal point !!!
replace$(string, ",",".")
so you'll have to come up to this :
e.g. strsql = "insert into table1 (col1) values (" &
Replace$(Format(numcol, "###0.00"),",",".") & ")"
I guess you don't need the ###-part, in fact, you only need the format if
you want control of the format, else you can use the cstr-function.
Replace$(CStr(numcol), ",", ".")

'A required privilege is not held by the client' when re-initalization

Hi all,
the sys admin has changed the service a/c to another admin. id. But now, i can't start the replication jobs even re-created the publication and subscription with the new admin. id. Any advise? Thanks in advance!

'Executed as user: test.com\admin. A required privilege is not held by the client. The step failed.'

Hi Stephaine,

How do your admin change the service account? He/she might use Windows Service Control Manager to change account. To solve the issue, please refer to this KB article (http://support.microsoft.com/kb/911305/en-us).

Thanks,

Peng

|||an issue i found was that sql server agent and ssis had been changed to not use the local system account. this caused me to continually get the dreaded --> "A required privilege is not held by the client" error. i fought with it all afternoon and eventually updated the services to use the local system account and it worked. perhaps this will save some other as much time as i wasted.

a minus b, how?

Hi, I know that under oracle you can do simple minus calculations of set
data extracted via select statements i.e.
select client from tableA
minus
select client from tableB
But how do ytou do this in sql?
I tried two methods:
method 1:
select a.client from tableA a where a.client not in (select b.client from
tableB b)
... this doesnt return any results
method 2:
select a.client, b.client from tableA a left join tableB b on a.client =
b.client
.. those results with b.client= null are the ones im interested in
I've noticed that method 1 and method 2 dont give the same results. method 1
gives no results, method 2 gives > 0 results. Whats the difference between
method 1 and 2, and my objective of setA - setB ?
any help most appreciated!

In SQL Server 2005 use EXCEPT instead of Oracle's MINUS.
In SQL Server 2000 use either the NOT IN method or your LEFT JOIN
method (add WHERE b.client IS NULL) or use NOT EXISTS.
The difference between your NOT IN query and your LEFT JOIN query is
almost certainly to do with NULLs in TableB. If a client in the
subquery is NULL then the result of NOT IN is always false or unknown
so no rows will be returned. Change your first query to:
SELECT A.client
FROM tableA A
WHERE A.client NOT IN
(SELECT B.client
FROM tableB AS B
WHERE B.client IS NOT NULL) ;

A little help with clustered SQL server setup.

Guys,
I keep getting errors while trying to install SQL 2K5 server on Win2K3 x64
R2 SP2 cluster.
The setup sequence was
1. Install SQL client/tools on all nodes
2. Install first instance of SQL server
3. Install SQL SP2 for client/tools on all nodes
4. Install SQL server SP2 for instance
5. Install second instance of SQL server
This step keeps failing no matter what I tried.
I did similar setup before in “slightly” different order and it works fine:
1. Install SQL client/tools on all nodes
2. Install first instance of SQL server
3. Install second instance of SQL server
4. Install third instance of SQL server
5. Install SQL SP2 for client/tools on all nodes
6. Install SQL server SP2 for all instances
With my current setup I don’t want (actually I can not) follow same order.
What if the first instance is already in production AND SP2 is applied
already, and then I need to install a new instance?
Anyway, setup keeps failing on remote nodes with this error:
(I tried both, GUI and command line with exact same result)
Running: LoadResourcesAction at: 2007/4/22 22:22:59
Complete: LoadResourcesAction at: 2007/4/22 22:22:59, returned true

Is the Cluster service account the same on all nodes?
