Performance Degradation - Any Ideas?
Apr 11, 2001
Hi all,
Up until recently one of our SQL 7 databases has been running quite happily. However over the last 2 weeks the users have started to complain about performance levles, operations that would normally take 2-3 seconds now run for about 40 seconds. I have rebuilt all indexes and even ran update statistics althought both the 'Auto create Statistics' and 'Auto update statistics' are turned on. This failed to help so I ended up stopping and starting SQL server but still no luck.
I have run a DBCC SHOWCONTIG and the fragmentation is well within acceptable levels, scan desnity is at 94%. The only other thing I can think of is to reboot the NT server as it has been up for 67 days now. Can anyone else think of anything I might have overlooked?
All replies welcome.
Thanks.

Hi,
I have an ASP.NET application used in my university for student management. Any now and then the application throws an error like "DataBinding: 'System.Data.DataRowView' does not contain a property with the name XXXX" where XXX may be different. Of course that this properties exist and they are generated ok by the stored procedures.
After an recopilation everything seems to work nomally for a while.
I did not succeed in identifying the moment when the error is thrown but I suspect some reports in sql reporting services that lead to a server overload ??? that also is strange because the server specifications are quite ok, I think:
- OS: Windows 2003 R2, 64 bit
- SQL Server 2005 Standard, 64 bit
- 8 GB RAM
- Intel Xeon E 5345 2.33 Ghz (2 quad-core)
I would need help for:
- identifying the moment when this error occurs and _why_
- how could I repair it
- how could I distribute the load on more cores (from time to time Process Explorer from Sysinternals shows that only 1 core from 8 is working at full capacity)
Thanks,
Catalin

Thanks in advance !
We are having a situation (PROBLEM) with our DW - SQL SERVER 2000 SP4 ENT X86, it suddenly slowed a lot.
CPU Usage : 20%
IO : AVR DISK QUEUE LENGHT Between 1.5 and 2 (rarelly spikes (20/40)).
MEM : 8 GB, 6GB to SQL SERVER.
All the code that is running against the DB is fined tuned ( Most tables are Index Seeked with Clustered Indexes ), biggest table 450 GB.
No Lock Waits ( Except the main process(spid) that is showed has locked by it's own spid ( latch_xx (sh,ix)).
I guess that the problem is related to storage, because it is only doing 1-3MB sec (sometimes 20MB/sec).
PerfMon ( PROCESS SQLSERVER ( DISK Read Bytes ( between 1-3MB sometimes 20 MB/s), Disk Bytes Write Bytes/Sec same as Reads).
No more sql server instances or other software hogging the server.
I can't understand why the SQL SERVER is never using the IO it is used to use (25MB/S).
I don't see any DISK QUEUE on the Partitions that are used to store the datafiles/logfiles)
No Pages splits in the SQL SERVER ACCESS METHODS.
Sometimes I get about 1 GB in dirty buffers.
98 % Cache Hit Ratio.
ALL points to IO contention, but the counters from windows don't indicate this.
All help is REALLY appreciated.
Best Regards.

Hello,
Working with SQL Server 2000, I have a table with the following structure:
ID (INT)
userID (INT, foriegn key)
productID (INT)
productQTY (DECIMAL(5,2))
purchaseDate(smalldatetime)
I have about a 1000 users, entering about 20-30 rows per day each, i.e ~20,000 - 30,000 new rows per day. The table might be queried with a simple "SELECT" for the products a user ordered per day or per time frame (purchaseDate column).
My question (finally) is - when should I expect to see performance degradation? Is there anything I can do to prevent it (i.e splitting this table somehow to several tables)?
Thank you all in advance

Hello guys,Wonder if any of you could help me out here. I have just created annew empty database and imported data from another database into it.This was done with the import wizard from MMC.First thing that I noticed was the size difference, the old databasewas well over 1GB, but the new one was only about 400MB.Second thing I've noticed, and this is the problem, is that accessingthe new (smaller) database instead of the old one causes a huge speeddegradation, about 5 times slower than the old version.We are using MS SQL Server 7. Any help would be very gratefullyreceived.RegardsGethyn

Hi all.
Any assistance would be greatly appreciated.
We recently created transactional replication to hopefully improve performance issues we were expereincing. The replication is between 2 SQL Servers (2000), and since we have introduced the replication, the performance has degraded considerably.
I will try and explain the scenario.
We have a primary db that our internal users use and we also have the newly replicated db that our website and another application use. The users are complaining that the website and the internal application is extremely slow and I was just wondering if it is possible to do an Index Tuning on both the primary db and replicated db based on trace files so as to create new indexes or would this have an impact on the replication?
Thanks in advance.

Hi all,
I am experiencing performance problems with one of my stored procedures. When the stored procedure is first compiled an executed, it behaves as expected (it usually takes 1 or 2 seconds to complete). But its performace it is degradated, so in 1 day, it usually takes 120 seconds to complete !!!. Once the stored procedure is compiled, its performance it is then the expected.
It is a complex stored procedure with two integer parameters with only one select, but composed by multiple views and sub-queries. We have been trying to break the query into small pieces using temporary tables but without success. The SQL Profiler shows an unusual number of reads when it goes wrong (more than a million reads).
I think the problem is in the execution plan. I know than compiling the stored procedure, the problem is fixed, but I do not know exactly when and why it starts to happen.
The stored procedure is running under the following configuration:
- Microsoft SQL Server Standard Edition (64-bit).
- Version: 9.00.1399.06
- RAM 16 MB
- 8 CPUs
Anyone has any ideas or possible solutions?
Thanks in advance,
Carlos.

Hi all
I am fishing for ideas on the following scenario and hope someone can point me in the best direction.
I create a new table and insert data from relevant other tables but i want to set the data in the new table colums to set widths that have leading zeros where applicable.
I.E the new table column is varchar (10) the data going in to the column is coming from another table where the size was varchar (8) but the data was only 2 characters in size so i want to pad it out to the full new varchar (10) with leading zeros if that makes sence.
I am really just trying to get some ideas on the best possible way to do this thanks.

I have a table with 18,000 records with beg_eff_date since the year 2005. I need to separate the entries based on their daily activity. For example if Beg_eff_date 01/0/2005 then day is "1" if Beg_eff_date is 01/27/2005 then the day is "27".
Repeating the same process until I reach "NOW" present time. Any ideas of how can I do this?

Hi everyone
We've got currenlty around 500 dts 2000 in production.
In order to know in what ETL processes we have Oracle connections, or FTP tasks or whatever, we did a VB6 app using dtspkg.dll which load all the properties for each DTS into Sql server tables. So that, then you could see from a specific DTS how many connections, Sql Tasks it had and so on..
How to accomplish the same with SSIS? I know, doing the same but using .Net, of course, but is there any else approximation? I am little bit concerned when we will have hundreds of them up.
Maybe 2005 is offering this feature automatically, I don't know.
Thanks in advance for your time/advices/ideas,

Am working on an SSIS project and I am not sure how to handle this situation. I have four tables in two completely separate networks {AB} {CD} and I want to populate one of the tables D based on the information from tables A and C with the following scenario I get data from from table A make a lookup transformation to check what did has changed if the data has changed or if there is a new entry in table A get the identity key from table C {they both share a common field} and add the identity key as part of my data inserted in table D
A ----lookup <
data that has changed --- get the identity key from C ---- insert data from table A + identity key into D

I have a text file that I am importing in a data flow task. Not all of the rows are the same, there are "header" rows that contain a company code.
What I want to do is keep that company code and append that to the row of text that I am writing to a CSV file.
Since you cannot change variables until the post execute, what are my options?
Hope that's clear
Thanks!

I have some performance issues which I can not explain; The database it is running on on a dedicated SQL server box with 8 cpu€™s 4 GB memory. Users are connecting with a fat client.
There is hardly on users using it but they are getting long delays. So I kicked of a profiler trace and sp_blocker. I noticed some queries taking over 30 sec to complete in profiler but when I run them in query analyzer they run in under a second.
I check the output from the blocker and there was no blocking over that time period and it was the only processes actually running.
How can it be so slow I have run out of ideas please any ideas would be welcome
Many thanks

I'm looking for Ideas on how to handle a Pldege Reminder process. For example; a pledge is made to pay $2400 over the next two years. They will pay $100 per month and each month a reminder will be sent. No real mistery if there is a balance you send a reminder. My problem is how to handle things like what if they want to pay quarterly or annually and how to determine if a payment is really due based on when they paid last, etc... You most likely see what I mean.
If anyone has done this in the past and/or has any ideas and is willing to share I would greatly appreciate any help.
Some stuff that may help you help me better:
tblClient (ClientID)
tblPledge (PledgeID, ClientID, PledegedAmt, PledgeDate,Frequency,NumberYears)
tblPledgePayments (PmtID, PledgeID,PmtAmt,PmtDate)

I'm new to asp.net. Please help me with some ideas about the design of databases and interface of the web site.
We are a public school district, I want to create a website for families to go on line to update their family and student's demographic information. Basically I put the students' infomation pulled from our student information system software on the web, the parents can log in on line to update it at the beginning of school year. After that, I will create some report and let secretary manually do the update to our student information system.
The demographic infor includes 3 parts,
1. family street address, city, state, zip2 guardian1 primary phones,second phone, emails. primary phones,second phone3, student date birth, gender. may have multiple students in one family
But how can I track which field parents changed, shall I do it in programming in the web form, or later when I create some kind of reports. For I only want to pull students with the fields that updated and give them to secretary to update manully, and I don't want to generate a full report and let them compare which field is changed and then update, it will take them too much time.
Thanks much in advance

I've read thru all the threads here which say basically the same thing, use a drop table & then a create table to clear the spreadsheet. My problem is the process works the first time to create the table in a new Excel file but fails to clear excel after that. The processes drop, create, & pump data all work without fail but the spreadsheet data is appended to. I've used the wizard as well, saved the package and ran it again without success. Anyone ran into this one?

I have tried to make my basic audit log do more, but i haven't gotten very far;
In my basic audit log, i record this information:
table
type of change
field modified
old value
new value
db user
date/time
This audit records everything, which is great, but it cannot relate information when i go back to analyze the changes; for example, when a "directory" record is added, a user's information may be entered into several different tables, such as:
name (different table)
addresses (different table)
phone numbers (different table)
If one wanted to look up the changes to addresses of a person in the directory based on the person's name, i could not do it with my existing audit log because the addresses would be in a different table than the name table and there is no relating data in the audit log to relate the address changes to a persons name;
What might be a solution? I have tried a few approaches and am at a loss;
Thank you!

To Whom It Concerns - MS Product Design - SQL Server Reporting Services:
I've been working with an ASP.NET web based project utilizing SQL Server Reporting Services for a while and have some things that I think need to be addressed in the next version:
1) I finally got security working utilizing the form based authentication of my Web based app and passing that to SSRS through the ReportViewer control. Not that it was easy. From what I see, a lot of people are having problems with this and so I didn't feel like I was alone. That said, instructions on how to do it need to be easier. Ultimately, it would be better if on the ReportViewer control, you could add properties as follows:
* Impersonate SSRS User
* Impersonization Password
2) Maybe I'm missing something, but in the web app the system logs in to different production databases based on the user id. The only way that I can figure out how to make the same reports available to each database (all on the same SQL Server DB) is to copy the reports and change the data source in the copied directory to copy to the new DB in SQL Server. Could ReportViewer contain a property that allows you to override the connection sring?
3) You have the ability to create PDF's. This is a very nice feature. However, I would like to extend the capabilities that you have. I want to be able to embed a PDF inside the report and have it generated in-line with the report. As an example, I have meta data concerning the PDF kept in the database. When the report prints, I want the meta data printed and the full PDF referenced by the meta data to print. I actually posted a message concerning this to find that there is no solution - I've seen that many people have looked at the message indicating that they are interested in the same feature.
4) It would be nice to have additional controls available - panel, calendar , checkbox, checkboxlist, radiobutton, radiobuttonlist and hyperlink in particular.
5) Dashboard widgets that we can use. Your promoting SSRS as a way to build data decision front ends. It would be nice if out of the box SSRS included several widgets that we could use as indicators to metrics being tracked by the system. As it stands, I can do simple bar, line and pie charts and that is about it. No progress bar, no guages. It would be nice to have some sexier graphing components.
All in all, I do like the product. It was a pain to get setup due to the authentication issues, but I do like it.

Hi,
I want to write a sproc whose main table is Order and it inner joins another table called OrderShipTo with a one to many relationship so the way i have written the first query is as follows
SELECT
o.OrderId,
o.OrderDate,
o.PlanId,
o.CreatedByUserId,
o.Quantity,
o.BillToCompany,
o.BillToContact,
o.BillToAddress,
o.BillToCity,
o.BillToState,
o.BillToZip,
o.BillToEmail,
o.BillToPhone,
o.ShipToIsBillTo,
o.BookTypeId,
o.RequiredDeliveryDate,
o.SpecialInstructions,
o.ApprovedBy,
o.ApprovedByPhone,
o.ApprovedByEmail,
os.ShipToId,
os.ShipTypeId,
os.ShipToCompany,
os.ShipToContact,
os.ShipToAddress,
os.ShipToAddress1,
os.ShipToCity,
os.ShipToState,
os.ShipToZip,
os.ShipToEmail,
os.ShipToPhone,
os.Quantity
FROM
[Order] o
Inner Join OrderShipTo os on o.OrderId = os.OrderId
WHERE
o.OrderId = @OrderId
So suppose if i give an OrderId of 15 In the OrderShipTo table they may be 3 Or 2 or none entries for this order in the Ordership to Table So if there is 3 entries in the OrderShip i will get 3 rows of data which is correct... But i just want o.Columns to appear once and i want n rows for the os.Columns to appear.
So in Order To acheive i wrote this query DECLARE @OrderId int
SET @OrderId = 311
SELECT
o.OrderId,
o.OrderDate,
o.PlanId,
o.CreatedByUserId,
o.Quantity,
o.BillToCompany,
o.BillToContact,
o.BillToAddress,
o.BillToCity,
o.BillToState,
o.BillToZip,
o.BillToEmail,
o.BillToPhone,
o.ShipToIsBillTo,
o.BookTypeId,
o.RequiredDeliveryDate,
o.SpecialInstructions,
o.ApprovedBy,
o.ApprovedByPhone,
o.ApprovedByEmail
FROM
[Order] o
WHERE
o.OrderId = @OrderId
EXEC usp_OrderShipToLoadByOrderId @OrderId
But at the end i want all the rows o.Columns + the rows from os.columns... I also tried giving a union of both the tables but that didnt work of type mismatch..
How can i acheive that???
Regards
Karen

I have about 20 remote databases that I need a query/scheduled task to run that generates a .rpt file. That part I can get.
However, I need to get this file to another company (via email or ftp, etc) and make it automated.
For example:
Scheduled task runs twice a month and generates a file that then needs to be emailed to an individual or ftp'd to a ftpsite. Is there a way to do this in SQL 7.0 (or 6.5)?
Thanks for all your help,

SELECT DISTINCT WO_NO, wo_type, wo_status (incomp,compl,open), wo_status_code, wo_create_date, wo_post_date
I need to do a stored proc in sql server 2005 where I have to count the total work orders based on their wo_type + wo_status, i.e. open, compltd, incomplete. For example I may have (wo_types) AB, AC, AD, orders that are in open status. I need to count the total AB_Type, AC_Type, AD_Type then the total of all 3 in another column (as Total Open). I must do this for all wo_status.
I also have to allow the user to be able to enter the date they want. I.e. if they would want to know on 3/17/08 how many orders were opened that day only. I know I have to use a parameter for this but how do i do that?
Should I do separate select statments for each status, multiple tables ?
Also for 'open' wo_status the wo_status_code can change from O to S but it is still considered 'open'. For this wo_status how can I get the most recent status_code for the open order, i.e., I want to count a particular 'open'work order's - most recent status_code in the work order count for a given wo_type -->> the order should only be counted once on any given date entered. So if the status changed from O then S the same at 1pm then 2pm, respectively, then only the 2pm status should be counted. Thanks in advance for your assistance.

This way the data will stay together. The secondcolumn would be just text, varchar(100).I'd like to end up with a table something likeUSER_ID, GROUP_MEMBERSHIP, GIVENNAMEIn the example of robert.camarda, that user belongs to 7 groups, sothere would be 7 records, one for each group. I think once I have thispart, I can build my final table with PK's an all the good-housekeeping of a SQL Table.Now the part that I have no idea how to solve:How do I convert the data from unfriendly for databases, to something Ican use?1. I know I have a new user when I find dn:2. I know I am done with the user when I get a blank (null) line.3. I know what I want to populate rows with name and the contents onceI find rows starting with memberOf:4. It appears there is a max line length that LDIFDE will export, andstarts a new line. So, it will be necessary to join lines.I would think this is a combo of CURSORS, a do/while loop and otherassorted magic.If someone can help me get started, I would have something to reseachor model from. As of now, im staring and a blank page and not sure howto start. Maybe someone knows of a simular problem that can share theSQL.TIARob

I would like to write a user defined function that takes as an input a varchar and returns an xml. If the string is valid xml the function would just return it. If the string is not valid xml then the function would encode the value before returning it.
The function would look something like this:
Code Snippet
CREATE FUNCTION dbo.EncodeXMLIfNotValid (
@InputString varchar(max)
)
RETURNS xml
AS
BEGIN
DECLARE @xml xml
BEGIN TRY
SET @xml = CAST(@InputString as xml)
END TRY
BEGIN CATCH
SET @xml = '<![CDATA[' + @InputString + '>]]>'
END CATCH
RETURN( @xml )
END
However, after writting this I figured out that using BEGIN TRY and CATCH is not allowed in a UDF.
Any thoughts or ideas how I could write a function with this behavior?

Hi,
I need some help regarding SSIS.
I have a table containing a list of source table names to be transferred to destination.I need to pass each and every table name as a variable and based on the name of the variable I need to select data from source and insert into destination.The source and destinations are on 2 different servers.The source tables have different metadata (different column names and data types).Any help how to implement this would be greatly appreciated.
To be more clear I have List table which has below format
TABLE NAME
CUSTOMER
PRODUCT
INVENTORY
Customer , product, inventory are tables names. So my package should first go and collect the table name from LIST table and then transfer the Customer table data from Server A to Server B. This should be repeat untill all the tables listed in LIST table are transferred.

I am trying to insert a value into a field in a database named ASPNETDB.MDF. The table name is "profiles_BasicProperties" and the field name is "UserID". I get an error when I attempt to do this. See the code I am using to try to do this below...and then the error that I get which is further down in this post. Note...both the code and the database are on my laptop. I can connect to the database just fine using Server Explorer in MS VS 2005. Thanks in advance for any help anybody can offer...
Here is the code I am using:
<%@ Page Language="VB" MasterPageFile="~/Master02.master" Title="Create Your Free Account" Debug="true"%><%@ Import Namespace="System.Data.SqlClient" %><%@ Import Namespace="System.Web.Configuration" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder_Main" Runat="Server">
<script runat="server"> Sub CreateUserWizard_CreatedUser(ByVal sender As Object, ByVal e As EventArgs) Dim CWZ As CreateUserWizard CWZ = CType(Me.LoginView1.FindControl("CreateUserWizard"), Wizard)
CreateUserProfile(CWZ.UserName)
Private Sub CreateUserProfile(ByVal UserName As String) Dim conString As String = WebConfigurationManager.ConnectionStrings("Main").ConnectionString Dim con As New SqlConnection(conString) Dim cmd As New SqlCommand("INSERT profiles_BasicProperties (UserName) VALUES (@UserID)", con) cmd.Parameters.AddWithValue("@UserID", UserName) Using con con.Open() cmd.ExecuteNonQuery() End Using End Sub
</script>
...and here is the error and stack trace (the offending Line 49 is in bold):

Hello, i am trying to get this to work, i made a SP that send internalmessages to x number of users, the users is located in a variable called @To, they are seperated by commas.
INSERT INTO [dbo].[post] (touser, fromuser, subject, body, recived, w, a) (SELECT s.nstr, @From, @Subject, @Message, getdate(), 0, 1 FROM iter_charlist_to_table(@To, DEFAULT) s)
the function iter_charlist_to_table takes the usernames inside of @To and returns a table of usernames, i then want to insert a record for each of these users.
When i try to run this:
EXEC SendInternalMessageToUsers@From = N'nouser',@To = N'Dirk,piffo,Steve',@Subject = N'Test',@Message = N'This is to test message'I get the following result:
Msg 512, Level 16, State 1, Procedure LaberMail_SendInternalMessageToUsers, Line 36
Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
The statement has been terminated.

I installed MSDE. Then I changed the name of my machine. Then I uninstalled MSDE, so I could create a new, properly-named instance.
Now, when I try to install, the installer gets about 75% of the way through the "gathering information" stage, and hangs, every time. I have to kill it with Task Manager.
Help! What can I do?
Extra info: I thought maybe the problem was related to Norton AV, so I uninstalled that. While that was uninstalling, the installer announced that there was a "suspended" install of MSDE that needed to be cleared. So I said, yes, clear it. How do I find out if there are other suspended installs in progress?
Thanks...

Today when I came into work, I noticed all of my jobs failed on a particular server. I tried to manually kick off the packages, but to no avail. Both the job history and the error message from the packages state a timeout error.
Any idea on this? Also, I have no problem running a query from query analyzer...even on a remote machine.
Any help would be appreciated
Trevor
