Well, what do YOU think the sql should be? Have a try, post your sql and then someone may help you.

Thank you. OP was beginning to sound like an annoying mooch who wants someone to do their work for them.

Not just the past two or so, but the OP was going on about the same thing the other day. Did get some replies. It just goes to show how true it is with my sig from John Simmons

Hi everybody,
I made a primitive cost control database system using Microsoft Access 2007 as a front-end (don't ask my why did I use Microsoft Access!!!) and SQL Server 2005 Enterprise as a back-end
This program depends on regrouping data, so I have sections and each section in front of it has the total of it's item
Everything is working smoothly, except that the last line in any list, which is empty, gives me #Error in calculated controls
What should I do to avoid that?
Thank you...

Hi! I have such problem: when my web application make a request to
MS SQL Server 2005, and the last one have to send back a lots of data, it's throwing an error:
"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
SqlException
"
But on all other cases, it works well. It's very strange I think. Have you any ideas?

Hi,
The first thing that comes in mind is timeout. What is your operation timeout defined in connection and how long the data retrieval is taking (until you get the error).
Another thing is your connection pool. Sure that the connection isn't aging out?
Few additional questions:
- is the request a select statement or procedure call
- check the state of the connection before executing the command. Is it open?
- does the error occur immediately or when some time has elapsed
- what about database server side? Do you see the open connection
- are you able to trace the statement execution at server side

Timeout is set to default, it's not defined in connection string. About connection pool - I don't know, I haven't direct access to this server for now.
Answer your questions:
- Request is a select statement
- I'm using linq database context
- error occurs after 10 -50 seconds.
- no, I don't
- no I'm not
This error occurs with 80% frequency, not always.
Thanks.

Hmm,
What you could try is (modify only one thing at once and if nothing is changed, return to original configuration):
- add connection timeout-parameter to connection string ("Connection Timeout=60 ") The default id 15 seconds.
If the server is running low on resources, it may be unable to give you a connection in 15 seconds.
- increase packet size by adding "Packet Size=16384 ". Default is 8192.
This way the server doesn't need to send so many packets especially when large amount of data is to be sended
- Try disabling connection pooling by adding "Pooling=false " to your connection string. Default is true.
This will eliminate possible aging problems in pool
if possible at database server side you should check:
- start the query and check in database, how your connection is doing.
This can be done by using Management studio or sp_who stored procedure. You should see your connection in "runnable" state
- check the error logs for sql server. When the query is returning you an error, is anything recorded in error log
And of course you could try to run the select statement using 'normal' SqlCommand class along with data reader without LINQ. Just to make sure that LINQ isn't causing any problems.
I'm sorry that I cannot be more specific, but the problem isn't the easiest one to solve.
If you find out anything, please post your findings

Situation changed, now it works, but not always. I reproduced the same query several times.
1. I logged in
2. Make this query - everything okay
3. Then I have tried to repeat it - exception occured
4. Then I made browser refresh(F5), and tried again - works well.
I have tried to reproduce the same actions locally - with the same database on my local MS SQL Server 2005 - everything good in 100%! I don't know what to say
|
|
|
|

Ok,
- When you say that situation changed, what did you do in order to achieve this change in behaviour?
- Do you close the connection after running the query and before the connection object goes out of scope?
Because what you wrote, it seems that something from the first execution is affecting the second, something that browser refresh resets.
If you could post the key-parts of the code (connection opening, partial connection string without any user information, command execution and connection closing) it would help a lot (I hope ).

My connection string:
"Data Source=dbserver;Initial Catalog=mydb;Persist Security Info=True;User ID=user;Password=password;Connection Timeout=60;Packet Size=16384;Pooling=false"
I could not pass all programming code, it's very huge, I'll describe common steps,so, I click some button then:
1. EntitiesDataContext db = MyProject.Misc.HttpDataContext<entitiesdatacontext>.Current;
2. Client client = Application.GetClient();
3. db.GetPartsByClientType(...)</entitiesdatacontext>
Here is this property for my class httpDataContext<t> for step 1:
public static T Current {
get {
string key = typeof(T).FullName;
T datacontext = (T)System.Web.HttpContext.Current.Items[key];
if (datacontext == null)
System.Web.HttpContext.Current.Items.Add(key, datacontext = new T());
return datacontext;
}
}
For step 2 . In function GetClient I'm using the same
EntitiesDataContext db = MyProject.Misc.HttpDataContext<entitiesdatacontext>.Current;</entitiesdatacontext> to get db context.
And then on step 3 my query executing several time in cycle "for".
I hope this information will help

Ok,
Didn't yet have any specific idea.
Is the connection open all the time during a single request? I mean that there is no way that the connection could be closed or disposed by your code before the failing statement?
Could you:
- wire StateChange event for the connection
- every time the state changes, write to a log file (or similar) both CurrentState and OriginalState from event arguments
- wire InfoMessage event for the connection
- write every element from Errors collection from message event argument. Also write Message and Source
- wire Disposed event for the connection
- when Disposed occurs, write info about this to the log file
- write to the log file every time you get data context from httpcontext
- write to the log file every time you call open method on the sql connection
- write to the log file every time you execute the statements (especially the failing one)
- write to the log file every time you call close method on the sql connection
This should give a good output which shows the order how things are happening and some extra info what is actually happening.
Another thing that I'm thinking of is that why this doesn't happen on your local SQL Server but happens if you try to use SQL Server on another server. This could be because:
- network problems (packets are occasionally not delivered)
- the server under heavy stress and cannot respond
What do you think, could the reason be in those?

no probs i got the solution i modified my query to
string sql = "select format([dateregistered],'MM/dd/yyyy') as Dates,[user],[client facility],sum([payroll score]) as LC from [sheet1$] group by [user],[client facility], format([dateregistered],'MM/dd/yyyy') order by [user]";
its working for me..........

Hi ,
I am working on some report generation project.Any idea about inserting data from MS SQL SERVER in MS EXCELL Sheet.
G Singh
|
|
|
|
|
This example is using SQL 2005.
Create a new Excel file: c:\testXL.xls
Open the file and write ID into the cell A1, FirstName into the cell B1.
Sace and close the file.
The code below will add 3 rows to the Excel file.
CREATE TABLE #T (ID INT IDENTITY(1,1), FirstName nvarchar(20))
INSERT INTO #T (FirstName) SELECT 'John'
INSERT INTO #T (FirstName) SELECT 'Kyle'
INSERT INTO #T (FirstName) SELECT 'Stacey'
INSERT INTO
OPENROWSET (
'Microsoft.Jet.OLEDB.4.0'
, 'Excel 8.0;Database=c:\testXL.xls;HDR=YES;'
, 'SELECT ID, FirstName FROM [Sheet1$]'
)
SELECT ID, FirstName
FROM #T
DROP TABLE #T
Remember, you have to have the Excel file closed while running the query.
In order to have the code above working PROBABLY you'll have to run also this code to enable *Ad Hoc Distributed Queries* usage.
EXEC sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
EXEC sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;
GO

I am using the SQL Server to send an email by executing the msdb.dbo.sp_send_dbmail stored procedure. The problem is that the command is executed but the mail is queued and never sent. That is the email is not being received by the destination. Can someone help me with it please?
Thanks
Regards

Check that you have a configured profile.
If you pass the profile name as a parameter to the procedure, make sure that the profile exists and is correctly configured.
If you do not pass the profile name, check that you have a public profile which is default or the user executing the command has a private profile.
Check (with Surface Area Configuration) that database mail is enabled. By default, it's disabled
Check that you are a member of DatabaseMailUserRole in msdb.
You can increase logging on mail using command:
EXECUTE msdb.dbo.sysmail_configure_sp 'LoggingLevel' , '2';
This may help to pinpoint the problem.
Information about the queue is retrieved as follows:
sysmail_help_queue_sp @queue_type = 'Mail';
Hope this helps you,
Mika

Hi i am getting probs in nested cursor...
Outer cursor i am getting managers...,
Inner cursor based on managers getting employee details...,
In this for all the managers the last employee records i am getting more than one time...,
This is my cursor:
DECLARE curMgr CURSOR FOR
SELECT distinct ManagerID FROM @tbl_TempManagers
OPEN curMgr
FETCH NEXT FROM curMgr INTO @mgID
Insert Into @tbl_TempEmployee Select MId,ID,UserName,EId from tbl_login Where Mid=@mgid
WHILE (@@FETCH_STATUS = 0 )
BEGIN
SET @EmpDetail = ''
SELECT @Count=Count(*) FROM @tbl_TempEmployee
--
SET @Counter=1
DECLARE curDetailList CURSOR FOR
SELECT distinct EmployeeName from @tbl_Tempemployee where ManagerId = @mgID order by EmployeeName
OPEN curDetailList
FETCH NEXT FROM curDetailList INTO @EmployeeName1
SELECT dbo.tbl_Login.MID,
convert(varchar(20),TSDate,101) as [Date],TSSubject as [Subject],TSDescription as [Description],
TSHour as [Hour],TSMin as [Minute],convert(varchar(20),CreationDate,101) as [Creation Date],
CreationBy as [Name Of Employee] FROM tbl_TSEnterData
INNER JOIN
dbo.tbl_Login ON dbo.tbl_TSEnterData.CreationBy = dbo.tbl_Login.UserName
where CreationBy=@employeename1
AND TSDate BETWEEN
CONVERT( NVARCHAR, DATEADD(wk, -1, @d) , 101) AND CONVERT( NVARCHAR, DATEADD(dd, -1, @d) , 101)
order by CreationBy asc,TSDate Desc
WHILE (@@FETCH_STATUS = 0 AND @Counter <= @Count)
BEGIN
SET @EmpDetail = @EmpDetail + @EmployeeName1 + ', '
FETCH NEXT FROM curDetailList INTO @EmployeeName1
SELECT dbo.tbl_Login.MID,
convert(varchar(20),TSDate,101) as [Date],TSSubject as [Subject],TSDescription as [Description],
TSHour as [Hour],TSMin as [Minute],convert(varchar(20),CreationDate,101) as [Creation Date],
CreationBy as [Name Of Employee] FROM tbl_TSEnterData
INNER JOIN
dbo.tbl_Login ON dbo.tbl_TSEnterData.CreationBy = dbo.tbl_Login.UserName
where CreationBy=@employeename1
AND TSDate BETWEEN
CONVERT( NVARCHAR, DATEADD(wk, -1, @d) , 101) AND CONVERT( NVARCHAR, DATEADD(dd, -1, @d) , 101)
order by CreationBy asc,TSDate Desc
SET @counter=@counter+1
END
CLOSE curDetailList
DEALLOCATE curDetailList
INSERT INTO @Result VALUES (@mgID, @EmpDetail)
FETCH NEXT FROM curmgr INTO @mgID
Insert Into @tbl_TempEmployee Select MId,ID,UserName,EId from tbl_login Where Mid=@mgid
END
CLOSE curmgr
DEALLOCATE curmgr
Actuall o/p have to be like this:
Managerid Date EID EmplName
22 7-2-2008 100 Name1
22 7-3-2008 100 Name1
Managerid Date EID EmplName
22 7-12-2008 101 Name2
22 7-23-2008 101 Name2
Managerid Date EID EmplName
23 7-22-2008 103 Name3
23 7-23-2008 103 Name3
Managerid Date EID EmplName
24 7-12-2008 104 Name4
24 7-30-2008 104 Name4
But,I am getting o/p of that cursor like this:
Managerid Date EID EmplName
22 7-2-2008 100 Name1
22 7-3-2008 100 Name1
Managerid Date EID EmplName
22 7-12-2008 101 Name2
22 7-23-2008 101 Name2
Managerid Date EID EmplName
22 7-12-2008 101 Name2
22 7-23-2008 101 Name2
Managerid Date EID EmplName
22 7-12-2008 101 Name2
22 7-23-2008 101 Name2
Managerid Date EID EmplName
23 7-22-2008 103 Name3
23 7-23-2008 103 Name3
Managerid Date EID EmplName
23 7-22-2008 103 Name3
23 7-23-2008 103 Name3
Managerid Date EID EmplName
23 7-22-2008 103 Name3
23 7-23-2008 103 Name3
Managerid Date EID EmplName
24 7-12-2008 104 Name4
24 7-30-2008 104 Name4
Managerid Date EID EmplName
24 7-12-2008 104 Name4
24 7-30-2008 104 Name4
Managerid Date EID EmplName
24 7-12-2008 104 Name4
24 7-30-2008 104 Name4
See that all the managers last employee record coming more than one time
Becoz of cursor loop i am getting like this...,
