If you delete rows in a table and do a full table scan...
Is that supposed to read up to the highest block/extent that the
table ever attended.(like in some databases I use)
If so what is the best way to take care of such tables in sql server.
I appreciate your responses

How would I go about finding out what my high-water mark would be for concurrent
connections over a period of time (SQL Server 7, SP 3 applied)?
Thanks in advance!!!

I have a SQL Server 2005 system that has been running for about 2 years. This morning nothing will connect. SQL Server Agent will not start. It gives me the message
"The request failed or the Service did not respond in a timely manner. Consult the event log or other applicable error logs."
The error log only states the SQL Server Agent cannot connect to server CANSPEC-TMMCSQLDEV and it is shutting down.
When i try to logon to SQL Server using Management Studio i get the following message:
"A connection was successfully established with the server, but then an error occured during the pre-logon handshake. Provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe. Microsoft SQL Server Error : 233"
The help for this error states that it could be caused by the fact that SQL Server does not allow remote connections. I have remote connections turned on.
Any ideas??

Attempting to upgrade standard edition to enterprise.
Tried running setup with the SKUUPGRADE switch per the documentation. Kept getting a modal message box that I had to use Control Panel to upgrade components. Searched Google & MSDN tried everything I found, no luck.
No problem, I'll backup, remove standard, and install enterprise.
Removed standard via control panel.
Ran Enterprise setup. On the setup screen everything is greyed out (e.g. disabled) except workstation components.
Install the workstation components, run it again, everything greyed out except workstation. Select again, says I have nothing to install.
Uninstalled via control panel.
Deleted the SQL Server directory from Program Files
Deleted all the files in WindowsTemp
Deleted every registry key with the words MicrosoftSQLServer in it.
Run install, everything greyed out except Workstation Components.
Okay I give up... Not sure what else to do except reformat the (#*$(@*&$(# computer which will take hours.
Any help would be greatly appreciated.

Is there a way to configure mirroring to go from High Availability to High Protection without having to reconfigure Database Mirroring? Using the interface in Management Studio, I can change the configuration option to High Performance, but not High Protection despite both of them being Synchronous.
If not, what are the recommended steps to configure the mirror once it already has been configured? Is just like initially setting up the mirror or would there be any shortcuts I could take? If I stop the mirroring and remove the witness, will the High Protection option be available?
Thanks,
J.
Hi There
I realise this is a stupid quesiton but i cannot really find any confirmation of this in BOL.
If you are running High Safety with automatic failover, when failover occurs does this automatically change to High Performance mode. SInce for failover to occur something has happen with the primary , it will be impossible to commit transactions on the new primary and mirror asyncronously since 1 of them is no longer available.
So am i correct in assuming that automatic failover also automatically changes the mode to High Performacne for that session?
Thanx
I am trying to select rows from a SQL2000 database table and then write a random number back into each row. I have already looked into do it all in a SP but there are well documented limitations for the SQL RAND function when called in the same batch, so I need to somehow do in .Net what I already have working in classic ASP.
I can't get the UPDATE (part two section) to compile. I don't know how to call the stored procedure inside the 'foreach' loop or extract the SP parameters. I have it working in classic asp but am having a lot of trouble converting to .Net 2.0. Is the below even close to working?
// stored procedure to write externally generated random number value into database
PROCEDURE RandomizeLinks@L_ID int,@L_Rank intASUPDATE Links SET L_Rank = @L_RankWHERE (L_ID = @L_ID)
// Part One select links that need random number inserted.
public DataTable GetRandLinks() { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString1A"].ConnectionString); SqlCommand cmd = new SqlCommand("RandomizerSelect001", con); cmd.CommandType = CommandType.StoredProcedure; SqlDataAdapter da = new SqlDataAdapter(); da.SelectCommand = cmd; DataSet ds = new DataSet(); try { da.Fill(ds, "Random001"); return ds.Tables["Random001"]; } catch { throw new ApplicationException("Data error"); } }
// Part Two I need two write a random number back into each row
protected void Button1_Click(object sender, EventArgs e) { GetRandLinks(); int LinkID; // this generates unassigned local variable "LinkID' error int LRank; // this generates unassigned local variable "LRank' error SqlConnection con2 = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString1A"].ConnectionString); SqlCommand cmd2 = new SqlCommand("RandomizeLinks", con2); cmd2.CommandType = CommandType.StoredProcedure; cmd2.Parameters.AddWithValue("@L_ID", LinkID); cmd2.Parameters.AddWithValue("@L_Rank", LRank); SqlDataAdapter da2 = new SqlDataAdapter();
int RowIncrement; RowIncrement = 0; DataTable dt = GetRandLinks(); foreach (DataRow row in dt.Rows) { System.Random myRandom = new System.Random(); int LinkRank = myRandom.Next(25, 250); LRank = LinkRank; da2.UpdateCommand = cmd2; RowIncrement++; } }

Hi,
I am encountering a problem. There are lots of duplicate rows in the cobol flat files (due to improper data entry and missing columns values )from where I am transforming data to sql 7. 0 tables using DTS. After transformation , can I some how mark the duplicate rows ? it is not for the purpose of eliminating them, but to enter the missing values and make all the rows complete and unique.
I have the transformed table as a temporary table. Can I add a column like 'status' etc.. and have the column values marked '1' for the repeating rows etc....
Can anyone suggest 'any' possible way of implementing it ?
Thanx

One of the tables in my database was originally designed with a question mark in the column name. When creating my query for jdbc i did this:
String q = "o."Cancelled?" from ORDERS o";
However, this query gives me the following error message:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]Invalid column name 'Cancelled@P1'.
Is there a way of stopping the driver from turning the '?' into '@P1'?
I have tried single quotation marks instead of the double ones around the column name and also back ticks, but with no success.
I have also seen an option in a local ODBC connection I have created an option for ansi quoted strings which solves the problem for oDBC queries, is there an equivilant for JDBC?
Thanks to anyone able to help!
Sincerely,
Andrew
I can find nothing in MSDN or the Web to explain
the question mark in the WHERE clause here:
SELECT DEPARTMENT.ID,
DEPARTMENT.NAME,
DEPARTMENT.FUNDCODE,
DEPARTMENT.DEPTCODE,
DEPARTMENT.DEFAULTCONTACT,
CONTACT.LNAME AS DEFAULTCONTACTLASTNAME,
CONTACT.FNAME AS DEFAULTCONTACTFIRSTNAME,
CONTACT.POSITION AS DEFAULTCONTACTPOSITION,
CONTACT.PHONE AS DEFAULTCONTACTPHONE,
CONTACT.FAX AS DEFAULTCONTACTFAX,
CONTACT.EMAIL AS DEFAULTCONTACTEMAIL,
DEPARTMENT.ISACTIVE,
DEPARTMENT.ISACTIVECOMMENTS,
DEPARTMENT.POSTUSERID,
DEPARTMENT.POSTDATETIME
FROM TDEPARTMENT AS DEPARTMENT
LEFT JOIN TCONTACT AS CONTACT
ON DEPARTMENT.DEFAULTCONTACT = CONTACT.ID
WHERE DEPARTMENT.ID = ?
ORDER BY DEPARTMENT.NAME ASC
I have never seen a question mark in the WHERE clause like this before.
If I run such a query in Query Analyzer I get:
[Microsoft][ODBC SQL Server Driver]COUNT field incorrect or syntax error
Can anyone explain: "DEPARTMENT.ID = ?" ?
Hallo All,
Can somebody explain why the same function works different with MS SQL 2000 and MS SQL 2005?
On both systems 2000 and 2005 I have 2x databases named ACCT and PROD (actually only a test environment).
On both systems I try to execute the following statements:
BEGIN TRAN TRAN_01 WITH MARK 'My TRAN_01'
USE PROD
INSERT INTO [PROD].[dbo].[_PROT]([STR_COMMENT], [R_NUM_T1], [R_NUM_T2])
VALUES('PROT_COMMENT', 1004, 1004)
USE ACCT
INSERT INTO [ACCT].[dbo].[_PROT]([STR_COMMENT], [R_NUM_T1], [R_NUM_T2])
VALUES('PROT_COMMENT', 1004, 1004)
COMMIT TRAN TRAN_01
After executing the statements I start the following query:
SELECT * FROM [msdb].[dbo].[logmarkhistory]
On MS SQL 2000 I get as results:
PROD TRAN_01 My TRAN_01 SUPPORTAdministrator 3944000000107600001 2006-03-29 17:15:13.930
ACCT TRAN_01 My TRAN_01 SUPPORTAdministrator 8000000009200001 2006-03-29 17:15:13.930
Seems to be correct. I think it is the way it should work according to the documentation.
On MS SQL 2005 I only get the following results:
PROD TRAN_01 My TRAN_01 SU 29000000107800001 2006-03-29 17:31:32.283
There are no entries in the table for the ACCT database and the account / user_name is shown incorrectly.
It seems to be an ERROR in the processing of such marked transactions in MS SQL 2005.
Hi,
For the last week, our production SQL server is running very slow and causing the CPU usage to go 80-100 % almost all the time. This causes certain queries to time out. Our application has never timed out before ever. Also, we did not do any updates on our production machine or installed anything recently.
Has anyone of you ever experienced this issue? If yes, then what did you do to resolve it? any help would be greatly appreciated.
Thanks for your help!
I have a 2003 server with sql 2005 on it and the sqlservr.exe is using 880 meg of memeory and it will climb to 1.4 gig. if i reboot server it will go back to 100 meg and slowly climb back up. any ideas i am not a sql guy.
View 2 Replies View RelatedWe have a live server that has had very high CPU usage in the last few days, therefore the site is extremely slow. There are about 60,000 users per day on the average. It always had high CPU usage, but not as bad as in the last few days, in the 90s, sometimes even reaching a 100.
Any solutions? I've run SQl Profiler to check on queries that have high CPU usage. When I run the same queries on our staging server, they are very quick. For example, the same query can take 1 minute on stage, but 12 minutes on the live site. We do know that this is also related to traffic, during lower traffic times, the same query takes less time, but still never as fast as stage.
Oh yeah, it's SQL Server 2005 and asp code running IIS6 on windows 2003 server.
Please help. I really appreciate any advice. Thank you.
Hi,I've created a table in SQL Server 2000 and I'm now trying to searchthrough the data and return specific rows. I'm using this command:select * from Export where libelle_court='Recherche d'investisseurs'The problem is this: The search fails whenever there is a curlysingle quotation mark within the table field ( ' as opposed to ' ).For example, if the field entry in my table is this:Recherche d'investisseursthen both of the following commands retun no fields:select * from Export where libelle_court='Recherche d'investisseurs'select * from Export where libelle_court='Recherche d''investisseurs'However, if the field entry in my table is this:Recherche d'investisseursthen both of the commands quoted above succeed.How can I get SQL Server to treat the curly quotation mark correctlyand return the right results? I've tried changing the collation butwith no success.Thanks,Rob
View 3 Replies View RelatedI've been asked to look into the possibility of using SQL Server in a high availability environment. We have a few web based applications that use SQL Server back end DBs. What we are looking into is whether we can use multiple instances (on multiple physical servers) of SQL Server using some type of clustering/load balancing. I haven't worked with SQL Replication before, so I'm not even sure where to start in exploring the possible avenues we can explore.
Can anyone push me in the right direction? Any info would be greatly appreciated!

To All,I have a SQL2KSP3a database(<1GB) running on a 4x3GB physical CPU with4GB of ram. It is Windows Server 2003 with hyper-threading turn on.There are ~420 .Net users/cxns (fat client, no web/app servers) withconnection pooling and ~1 trx/sec. The database growth is neglegeableand actually is not even relevent which I will explain in a minute.99% of the trxs are from one SP that does a select. The resultsets arerelatively small as well 1~100 rows. Yes I have tuned it with indextuning wizard as well, changed the SQL memory configurations, etc....My problem is this...The first day after a reboot, the server runs 6%CPU during peak hours.During the non-peak hours until the next day something apparentlyhappens. The next day (2nd day after a reboot), it jumps to 40%CPUduring peak hours. The server will continue to run at 40%CPU duringpeak hours until the next reboot. This phenomenon has been occurringfor 6 months or more and the traffic on the server is the same for day1 as it is for day 2,3,4,... This database was on another server with100+ dbs and exibited the same behavior, thus bringing that server toits knees, and thus we had to move it to the server in question with noother dbs.I have googled my eyes out, Microsoft site, white papers, perfmon,SQLDiag, PSSDiag, execution plans, index tuning wizard, and the listgoes on! I currently have a case open with Microsoft that has beenopen for months now. I have been passed around to the 3rd "MS TechSpecialist". I have ran PSSDiag a total of 6 times for them for hourson end. I have changed MAXDOP. I could give more information, but Iwould be here for days. I am running out of patience/ideas andMicrosoft is apparently blowing smoke.Any ideas are greatly appreciated!Thanks in advance!JL

Thanks in Advanceshan
Our company recently combined our DBs into one SQL 2005 Server.
Dell Power Edge 1800 with 3.00 GHz Xeon Processor 800 FSB, 1 GB of RAM
Dell Power Edge 1600 with 2.80 GHz Xeon Processor 533 FSB, 1 GB of RAM
Combined into one:
Dell Power Edge 2950 Dual Core 1.6 GHz Xeon Woodcrest Processor, 4 GB of RAM
However, the CPU utilization on this new server is maintaining at about 90% with 3.82 GB of RAM used as well. It's a Windows Server 2003 R2 x64 edition running SQL Server 2005 SP2 x64. I have searched around Microsoft's website for any information that could be of help to me, but I was unable to locate anything. I was hoping that someone could provide some insight as to why this might be occuring. Or if this is a known issue.
Thanks,

We are using an IBM Xeon server with 4 GB RAM with windows 2000 server and MS Sql server 2005.
More frequently our server responce time is very slow, although the cpu utilization is between 7 - 10 %. we can not able to run even notepad on the server. we observed that the memory occupaid by the sqlserver prog is high. If we restart the server then it will return to normal level. But we do not want restart the server frequently.

We are using an IBM Xeon server with Sevrer 2000 and sql server 2005 with 4B RAM.
We noticed that the responce time of the server is very slow. During this time the memory occupancy by the sqlserver is very high. Althouh the cpu utilization is very low (7-10%) we are unable to run even notepad on the server. In some other situations the cpu utilization will be 100% (for more than one hour) during this time also the sql server occupaies more memory. If we reatarts the server then the problem will be fixed, but we do not want to restart the server very frequently.
Kindly provide us a suitable solution

Hi,
We are having a big performance issue at our site. Here is the configuration of the box running SQL Server 2005:
64 bit Windows Enterprise Edition + SP1
Dual CPU, 16GB RAM
RAID 1 and RAID 5 - internal
SQL Server 2005 64-bit Enterprise Edition
With SP2 (CTP from December)
The "Lock Pages in Memory" is set and is being run under the same account that is being used to run SQL Server Services.
We are noticing that under load, the CPU utilization becomes nearly
100%. I have researched this and have come across a couple of
posts that indicate that this issue was fixed in SP2 - example: One
post talked about the hotfix #716 which is also a part of SP2 but even
after the application of that service pack, we are still having this
issue. I haven't tried setting the parameterization option to
forced for the database yet.
Is this a known issue with SP2? If not, what can we look for and
fix in our environment? Please let me know if I can provide more
information.
I have a requirement to mark duplicate records when I pull them from the database.
However, I only want to mark the 2nd, 3rd, 4th etc record - not the first one.

I have about a 447 MB SQL server 2000 database on a desktop PC acting as a QA server. The hardware specs of the QA box are as follows:
CPU: P4 2.4 GHz
Memory: 1GB
Drives: 80 GB IDE
I recently purchased a Dell PowerEdge 2650 server to act as the staging box. The staging box has
CPU: P4 2.4 GHz
Memory: 2GB
Drives: 40GB SCSI, mirrored
I made a backup of the database on the QA box, and restored it on the staging box. Yet when I run something as simple as a select query (select * from <table>), the less powerful QA box is faster.
I figured maybe the statistics are different on the staging box. I ran dbcc showcontig to make sure the statistics were identical. Also ran RedGate's SQL compare and data compare to make sure everything was identical.
I figured maybe the query optimizer needs to be tweaked. I recreated the indexes and updated statistics on the staging box. The queries actually got slower as a result.
I thought maybe SCSI drives are slower. Tried breaking the mirror on the staging box. No luck. Put the mirror back in place, ran a test where I copied a large folder from one directory to another on the staging box. Repeated the same test with the same data on the QA box. The staging box was more than twice as fast than the QA box.
It doesnt appear to be a problem with the query, adjusting memory in SQL server has not effect, both boxes are using SQL server 2000 SP3, why is the bigger machine running queries hundreds of milliseconds slower than the smaller machine? Any help will be appreciated!
