We have a financial accounting system that has been certified for SQL 2005. Before I upgrade, I'm wondering if I should expect better/faster performance from SQL 2005 vs. SQL 2000?
Anything I should lookout for when upgrading to SQL 2005?
Thanks, Al
Hello!!
we use SQL2000(64bit) and we are considering our system to apply SQL2005
so i tested two SQL-Server on One Machine by installing each instance of them.
The RESULT..
i can't find difference of performance between two instance.
is there no impoving in Database engine?
* i'm sorry, for my poor sentence...

Hi,
I've passed my ASP application database from SQL Server2000 to SQL Server 2005 and have some problems with the
new functions in SQL Server2005, which do not acsept the Date & Time format as SQL 2000..in insert query.

Is there some some other way of resolving the problem?
Hello,
In the process of migrating a logshipped database (in non recovery mode) from SQL2000 SP4 to SQL2005 SP2, I got the following error (sorry for the french translation!):
---

Of course, the restore operation performs well when the destination is SQL2000. I suspect the integrity checker of SQL2005 to be less permissive, hence I run a checkdb on the original DB, which raise several errors, which are quite difficult for me to analyse:

Is there any easy option you can see to operate the transfer, since the backups I have from the DB already contain the data corruption?

Hi All,
I've got a stored procedure called from a trigger on another database. There are two xp_cmdshell statements in the procedure. One writes a couple variables, passed from the trigger, into a text file. The second fires off an executable that uses the text file via a batch file.
Here's the code that worked on the old 32bit SQL2000 box
Code Block
begin
declare @cmd varchar(150)
select @cmd = 'echo ' + @sVariable1 + ',' + @sVariable2 +' > c:aFolderTextFile.txt'
exec master..xp_cmdshell @cmd
declare @cmd2 varchar(150)
select @cmd2 = 'c:aFolderRun.bat'
exec master..xp_cmdshell @cmd2
end
The new box is 64bit SQL2005. When invoked the stored procedure executes without an error. The textfile is written sucessfully. But, the executable called from the second xp_shell statement does not produce the expected result. Because there is no error I'm having trouble determining where the failure lies.
To troubleshoot the problem I've tried:
Running the batch file from the command prompt in the system32 directory... Success
Using sp_xp_cmdshell_proxy_account to be sure of the credentials of the running xp_cmdshell... Failure
My questions:
Does 64 Bit SQL2005 have a different set of parameters when invoking an executable from xp_cmdshell? ie Do I need to rewrite the batch file?
Is there another way call an executable, SQLCMD maybe?
Any help is appreciated...
Code Block
The batch file if you're curious:
"c:Program Files (x86)someVendersomeAppsomeEXE.exe" "C:aFolderTextFile.txt"
I've come up against a wall with regards to adding login via a windows group. My end goal is to be able to manage sysadmin access to many servers via a domain group instead of via individual logins at each server.
I've got a mix of 2000 and 2005 servers, with a related issue for each. Searching far and wide has come up empty so far.
In each case below, the a login for the group was created via EM/SSMS, and set with the sysadmin role.
1. Domain Local Group
I added a domain local group "domainsql accounts" with myself among others as members, including the domain account for the sql and agent services.
Adding this group to SQL2005 worked fine, and authenticates my login as a member of this group. Oddly, xp_logininfo [domainsql accounts] , 'members' returns error code 0x8ac.
It does log me in, and it does correctly grant me sysadmin.
Adding this group to SQL2000 from EM, the group does not appear in the list for the domain. Typing it manually does recognize it as a group, but it does not allow login.
Review:
2000 fails login, fails xp_logininfo
2005 allows login, fails xp_logininfo
2. Domain Global Group
Next, I added a global group "domainsql dba", with myself among others as members.
This group IS viewable in SQL2000 EM to add as a login. Unfortunately, I still cannot login via windows auth. Even stranger, xp_logininfo [domainsql dba] , 'members' correctly returns the members of this group. I know SQL can authenticate that group, and I am part of that group, yet it won't authenticate my login?
SQL2005 fails to allow login but will also return member info via xp_logininfo.
Review:
2000 fails login, returns xp_logininfo
2005 fails login, returns xp_logininfo
The closest thing I found was a MS kb entry that suggested creating a local group, adding the domain group as a member of the local group, and adding a login for the local group. It didn't work.
Thanks for any offered suggestions

I have an application which stores records on a local SQL Express and I need to move the records to a SQL 2000 database. I have the SQL 2000 server linked in the Express Management Console (under Linked Servers). I'm trying to use a stored procedure to accomplish this, but get an error "Invalid object name 'ngtxa4-rsmsz-01.newpurchase.tblRequest'." Express uses a table named tblTRequest in the TempPurchase database, while 2000 uses a table named tblRequest in a NewPurchase database. Here is the stored procedure I'm using:
USE [tempPurchase]
GO
/****** Object: StoredProcedure [dbo].[InsertRequestToMain] Script Date: 07/09/2007 08:54:56 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[InsertRequestToMain]
AS
BEGIN
INSERT INTO [ngtxa4-rsmsz-01].newpurchase.tblRequest
(fldRequestDate, fldRequiredBy, fldUserID, fldWorkAreaID, fldVendorID, fldClassID, fldEstimate, fldMemo, fldStatusID, fldStatusDate, fldSystemID,
fldtmpRequestID, fldUpdateCode)
SELECT fldRequestDate, fldRequiredBy, fldUserID, fldWorkAreaID, fldVendorID, fldClassID, fldEstimate, fldMemo, fldStatusID, fldStatusDate, fldSystemID,
tmpRequestID, UpdateCode
FROM tblTRequest
WHERE (fldHold = 0)
END
Any assistance with this would greatly be helpful. Thank you.

Hi all, I m new to this forum and this is my first question. I m having 2 pages in my web site ... page 1 query directly to db using sqldatasource, the second page query through a BLL then DAL by following the step in this tutorial (http://www.asp.net/learn/dataaccess/tutorial02vb.aspx?tabid=63).... Page 1 is using a "Like" query search and the Page 2 is the normal displaying some product detail.... Under normal circumstances, one will expect Page 1 will be way fastest than the Page 2... however the problem is Page 1 is in thunder speed while Page 2 takes 10 secs to load... 10 seconds is really not acceptable... I really couldnt figure out what happens... both Page 1 and Page 2 are using the same connection string which connection through a DSN.... How is the connection different by using sqldatasource and DAL?? Could someone please help.... ThanksP.S. I m using a Pervasive database
View 5 Replies View RelatedHi y'all,
I've recently run a profiler on my code and following query took 7 seconds:
SELECT TOP 10 UI, COUNT(UI) AS Expr1 FROM table WHERE (UI <> 'custom_welcome') GROUP BY UI ORDER BY COUNT(UI) DESC
Is it possible to rewrite this so my code gets faster? It's also possible that it's due to the size of the table?
Thanks in advance! I'll let you know how long your query takes :)
I have a cursor prcedure that is pretty slow because as the cursor moves through the data I have three select statement on the same table to find other rows information. Is there a better way to do this?
Simple Example of Code is:
DECLARE MyVARABLES 1 to X
DECLARE c1 CURSOR
FOR
SELECT MyData1, MyData2 to X
FROM MyTable
FOR UPDATE OF MyUpdateData
--Start Cursor
OPEN c1
FETCH NEXT FROM c1
INTO MyVariables
--LOOP
WHILE @@FETCH_STATUS = 0
BEGIN
-----------------------
-- Get other rows data to add to this rows data ......GUESSING THIS IS THE SLOW PART as the table is LARGESELECT MyVar1 = MyData1
FROM MyTable
WHERE MyTableColumns = MyVariables AND MyTableColumns2 <> MyVariables2 --FINDS OTHER ROW (I have three of these)
--Calculate & Update
If MyVarable = 'this or that'
BEGIN
UPDATE MyTable
SET MyUpdateData = MyVar1 * x *y WHERE CURRENT OF c1
END
-------------------
-- NextFETCH NEXT FROM c1
INTO MyVarables 1 to xEND
CLOSE c1
DEALLOCATE c1
Hi!
I M basically an application developer & use simple sql queries in my programmings. I do not have much idea abt tuning/auditing part & thatswhy i m unable to answer them properly in my interviews. Can anybody give me some tips?????
Question 1:
In a stored procedure, One SELECT stmt is there & depending upon the @rowcount, it updates around 14000 records which is also written inside this stored procedure. Instead of writing this way, there is some other way which is faster than this. Can anybody tell me the correct way???
Question 2:Can anybody give me few examples like this?????? I need them desparetly.
Thanx. Bye.
I´ve created a class to make some standard transaction development a little bit faster. The destructor seem to run, but something makes this object slow down the database, if SqlTransaction and/or SqlConnection isnt manualy handled with the method Commit(). Any ideas on how to handle the SqlTransaction and SqlConnection better?
public class DataTransaction
{
private bool blnError = false;
private ArrayList arrErrorList = new ArrayList();
private SqlConnectionobjConnection = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["ConnectionString"].ToString());
private SqlTransactionobjTransaction;
public DataTransaction()
{
objConnection.Open();
objTransaction = objConnection.BeginTransaction();
}
~DataTransaction()
{
if(objTransaction.Connection != null)
{
objTransaction = null;
objConnection.Close();
}
}
public int ExecuteNonQuery(string Query)
{
int intRowsAffected = -1;
SqlCommand objCommand = new SqlCommand(Query, objConnection, objTransaction);
try
{
intRowsAffected = objCommand.ExecuteNonQuery();
}
catch(Exception e)
{
blnError = true;
arrErrorList.Add(e.ToString());
}
finally
{
objCommand.Dispose();
}
return intRowsAffected;
}
public System.Object ExecuteScalar(string Query)
{
System.Object objToReturn = null;
SqlCommand objCommand = new SqlCommand(Query, objConnection, objTransaction);
try
{
objToReturn = objCommand.ExecuteScalar();
}
catch(Exception e)
{
blnError = true;
arrErrorList.Add(e.ToString());
}
finally
{
objCommand.Dispose();
}
return objToReturn;
}
public bool Commit()
{
if(!blnError)
{
objTransaction.Commit();
return true;
}
else
{
objTransaction.Rollback();
return false;
}
objConnection.Close();
}
}
Hi,
Previosuly I was executing 2 DTS packages one afte the other manually and together they took a CONSIDERABLE time. The 1st one was pulling data from the OLPT, doing transformations and populating the tables in my Datamart and the 2nd one was doing a FULL process of all the dimensions and cubes.
However I tried scheduling the DTSs as jobs and havethen merged the 2 resulting jobs as a SINGLE job having 2 sequential steps. To my surprise the resulting job takes less than half the time (actually even lesser) as compared with my original approach i.e. running the DTSs. And I am talking about major improvement in terms of completion of the tasks here :)
Am i getting over excited here or is this natural? I assume that if this is correct then jobs much be some sort of "compiled" version as compared to DTS and maybe that's why I have this terrific improvement in terms of execution times.
I'll appreciate comments. Thanks
I have rewritten a stored procedure that consists of a single select that selects from a view. Essentially I combined the select in the view and the select in the sp into one select. I am now trying to determine if the new version is faster.
The estimated execution plan gives a ratio of 96% : 4% in favour of the new version when I run them together from a query window but when I try to time them I can't get a satisfactory result.
If I run each query once and display the difference between start and end time, they display 0. If I run each one 100, 200, etc times I get different results each time.
Is there anything I can do?
Hypothetically,
If I had a WHERE clause that had to compare a string to another string would it be faster one way or another if I broke it down to three different, smaller searches?
An example:
WHERE a = 'abc'
OR a = 'def'
OR a = 'ghi'
as opposed to:
WHERE a = 'abcdefghi'
