Application For Replaying A Table
Mar 17, 2006
I'm on a quest to find a way to "replay" a selected time range of records
from a table. The purpose is to simulate the pace and content of the records
in the table exactly as they were parsed during run-time. The ideal solution
would read records from a source table and write them to a destination table
as per a specified pace, i.e clock speed, 1/2 clock speed, 4x clock speed.
Just looking to see if there's something available currently before I jump
in and develop my own solution.
Thanks,
Chris

I'm currently working on a project at work to test the effects of database compression, trying to obtain measurable data on the impact of the compression on other server resources, and therefore whether the reduction in space used is worth the extra overhead. This has involved taking a trace of a production customer's workload for a period of time and replaying it against a backup using Distributed replay in synchronised mode.
I'm then taking a trace of that replay, as well as using perfmon to record useful data about the server, before and after compression is enabled. Finally, I'm loading the traces into a tool called Qure to analyse the impact of the compression on reads, writes, CPU, overall duration etc.
What I'm finding is that even across 2 different 'baseline' runs, which are replaying the exact same workload against the exact same database, performance etc differs to a significant enough degree that it calls into question the validity of the test. I can only put this down to the fact this server is on a VM, which is affecting available resources, which in turn affects execution plans the workload is generating and causes different replays of the same workload. I'm therefore looking at doing this on a standalone server, but I still can't be sure the differences will go away.
How to make tests such as this as similar as possible on multiple runs, when elements outside of SQL Server are in effect out of my control?

My Pocket PC application exports signature as an image. Everything is fine when choose Use SQL statements in TableAdapter Configuration Wizard.
main.ds.MailsSignature.Clear();
main.ds.MailsSignature.AcceptChanges();
string[] signFiles = Directory.GetFiles(Settings.signDirectory);
foreach (string signFile in signFiles)
{
mailsSignatureRow = main.ds.MailsSignature.NewMailsSignatureRow();
mailsSignatureRow.Singnature = GetImageBytes(signFile); //return byte[] array of the image.
main.ds.MailsSignature.Rows.Add(mailsSignatureRow);
}
mailsSignatureTableAdapter.Update(main.ds.MailsSignature);
But now I am getting error "General Network Error. Check your network documentation" after specifying Use existing stored procedure in TableAdpater Configuration Wizard.
ALTER PROCEDURE dbo.Insert_MailSignature( @Singnature image )
AS
SET NOCOUNT OFF;
INSERT INTO MailsSignature (Singnature) VALUES (@Singnature);
SELECT Id, Singnature FROM MailsSignature WHERE (Id = SCOPE_IDENTITY())
For testing I created a desktop application and found that the same Code, same(Use existing stored procedure in TableAdpater Configuration Wizard) and same stored procedure is working fine in inserting image into the table.
Is there any limitation in CF?

Professor Corrie.

Hi,I'm writing a telecom billing system where it is necessary to import csv delimited files into a sql server table.
1) The csv files to import differ in column arrangement i.e SQL server table arrangement = A, B, C, D whilst CDR = - , A, -, C, D2) The csv files are delimited via different characters i.e some are del.. by commas some by semi colons
I can import a CSV file from my application using a BULK INSERT query but only using CSV that resembles the structure of the table exactly
How can I pass a CSV to the table and state where I want each CSV column to fill a column in the SQL SERVER table
Below is how I am managing to pass a CDR to the SQL table that I have pre manufactured to resemble the structure of the SQL table Is there a way I can state which values from the CSV I want to pass to corresponding columns in the SQL table:
string conString = @"Provider=SQLOLEDB;Server=(local);Database=Billing;Uid=sa;Pwd=sa;";
for (int i = listBox1.Items.Count - 1; i >= 0; i--)
{
string strSQL;
OleDbConnection objConnection = null;
OleDbCommand objCmd = null;
objConnection = new OleDbConnection(conString);
string cdr = listBox1.GetItemText(listBox1.Items[i]);
strSQL = "BULK INSERT Campaign FROM '"+ cdr +"' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '')";
OleDbDataReader objDataReader;
try
{
objConnection.Open();
objCmd = new OleDbCommand(strSQL, objConnection);
objCmd.ExecuteNonQuery();
objCmd = null;
objDataReader = null;
objConnection.Close();
listBox1.Items.Remove(listBox1.Items[i]);
}
catch (Exception ex)
{
objConnection.Close();
}
objCmd = null;
objConnection = null;
}

Hopefully someone can at least point me in the right direction for moreresearch (e.g.: correct terminology). My only previous experience was justdumping data into a database using ODBC, and that was some years ago so nowmostly forgotten.I need to write an NT Service/Application (in C/C++) that will be gettingdata sent to it via SQL Server 2000. The data will arrive in my SQL Server(read-only access), via replication of tables from another remote SQLServer.My application needs know when new row are inserted, or updated so it can toread this data (needs to be quick/timely so hopefully no polling) to theninterface with other remote proprietary systems.T.I.A.PS: If you can recommend appropriate books on SQL Server 2000 that wouldalso be useful.

Hi everybody.
I created an application role in a database (DB1) and gave it all the rights on a view in DB1 which refers to a table located in another db (DB2). I also gave the rights to the app role on a table of DB1
I tried to use this app. role through the sp_setapprole launched by a user (server principal?) which is SQL Server administrator (and local administrator (Win 2003 Server)).
With the following query
SELECT USER_NAME()
I see that the approle is being used.
Than, if I query the table on DB1 everything works, but if I query the view, referring a table in db2 I get following error:
The server principal "NameOfServerPrincipal" is not able to access the database "DB2" under the current security context.
What should I do to make it work?
The table in DB2 has the same schema of the view in DB1 which refers to it.
I put the DB1 TrustWorthy and both the database have the db_chaining option activated.
Any idea on how to solve the problem would be widely appreciated.
Thank you very much.

Hi,
autorized user: sa
any user : nuran
temporary table: birtablo
I need a stored procedure will execute by sa and it will create some required temporary tables for each users. For example table name is birtablo. I mean sa will create table for nuran, and when I checked the owner of the table (birtablo) I want to see nuran not dbo.
sa will execute following command:
create table nuran.birtablo (...........)
Is it possible to cerate a table by sa on behalf of any user? If it is, could you please explain?
Thanks

Hi,
I have a table in my database with several car types, and the order I want for that table is:
Car_typeA_1
Car_typeA_2
Car_typeA_3
Car_typeA_4
Other_Cars_typeA
Car_typeB_1
Car_typeB_2
Car_typeB_3
Other_Cars_typeB
Car_typeC_1
Car_typeC_2
Car_typeC_3
Car_typeC_4
Car_typeC_5
Other_Cars_typeC
...
This table is more or less always the same, but from time to time I want to add a new car type, for instance; Car_typeA_5, but this new type must be located under the last register, in the example under ‘Other_Cars_typeC’. So, now the order is wrong, and when I want to display these car types to a web form object, the items will appear wrong ordered.
My question is: To order the values(items) correctly, Where I have to do it? In the web page (ASP.NET) code behind, or somewhere in SQL Server (for example in the Stored Procedure that passes the value to the application)? Or maybe in the same database table..?
Thank you,
Cesar

I need to randomly order the selected rows from my table. Is this better to do on the Application level or in a stored procedure using "orderby NewID()"?
Which is faster? There will be about 100 rows returned with 10 columns.

I am working with a vendor application called Cisco Unified Attendant Console - it operates on a Windows server with a SQL express database. The CUPs function of the application needs to reference a "contact" field with only the user portion of the contact's email address - generally, the contact's User ID will match the user portion of their email address, however, for this customer it does not (they use the employee number as the User ID and firstname.lastname as user portion of the email address.
Writing a script to accomplish the following:
The dbo.Contact_Properties table of the ATTCFG database has the following fields that we can work with:
Â
- First_Name
 - Last_Name
 - Email
 - User_Field_2
 - Contact_Unique_Ref (appears to be the field that ties all other contact tables together ?)
Is it possible to create a script that could run daily to either, combine the First_Name and Last_Name fields (with a period between) and populate the User_Field_2 field for each user, or populate the User_Field_2 field with everything before the @ symbol in the Email field for each user?
Also, by default the servers that this application is installed on does not have SQL Server Management Studio installed - is it possible to accomplish with PowerShell script triggered from the Windows Scheduler?

Hi
I have created a Visual Basic application the connects to my SQL database.
The appliction lets a user click on a button, data is retrieved from the database
and then formatted in Excel. Everything works fine on my machine (this is probably
because i have both VB and SQL installed on my machine)
I have created a .exe and deployed the application on some users desktops. The
problem is that when they click on a button - nothing happens. I dont even get any
error messages! Everything else appears to be fine. I have tested the DSNs and
they appear to be fine too.
Does anyone know why this would happen ??
Thanks, Ruaidhri.

Whenever a user logs on to SQL-Server there´s
a message in the application log of windows NT
like
"Login succeeded for user 'Domainusername'. Connection: Trusted."
Since we have lots of users. The application log fills up twice a day.
Is there any way to prevent SQL-Server from doing this ?
(I know that there are settings in the event-viewer which clear events
whenever space is needed).
Thanks.

I'm not sure if this is the right section for the question, but here goes...
I have an application that needs to be run in network client mode. This app is supposed to connect to a SQL 2005 db hosted on a server. As I procede through the installation process I get a prompt when i populate the serverdb information.
'The listener port was responsice, but did not return a primary port number for <servername>. Please verify that <servername> is a valid and running database before proceeding.
A little background is in order:
Host:
Server 2003 Standard
SQL Server 2005
Installed instance of said db
Client:
Windows XP Pro sp2
Network config:
We have a domain with about 125 workstationslaptops. Windows firewall is turned off using a group policy (makes it easier to push apps out to clients). For giggles I made exceptions to the 'turned off' firewall policies for the needed ports etc. This was done on both the host server and the client.
Thank you in advance.
