Really Weird SQL Failure
Jun 9, 2003
Last night our production server went crazy. The primary (production) database MDF file had size 15Gb and then for some reason the size became 0 (zero) K, So the SQL right away reported the error:
I/O error 38(Reached end of file.) detected during read of page buffer..
Error: 823, Severity: 24, State: 10
And the database became "suspected".
Now we restoring it, but have anybody seen such a thing before? I'm breaking my head to figure out what could cause this problem!!!!!

Hi all,
I am using ODBC to connect SQL Server 2000 + SP4 server runnig on Windows 2003 standard edition Server +SP1. But, sporadically my application server connectivity to DB fails and i receive the following error messages
[Microsoft][ODBC SQL Server Driver][DBNETLIB]ConnectionWrite (WrapperWrite()).
[Microsoft][ODBC SQL Server Driver][DBNETLIB]General network error. Check your network documentation.) In D:de.cpp 702 Apr 12 2006 20:34:47

I have a dts package that is mysteriously changing back to a previously saved version. Package is saved, and re-opened with saved changes, then moments later opened again to have been reverted back to an older version. Has anyone ran into this before?
The only thing that I can think of is that if a version of the package is left open on some other machine (as the older version0, it may be auto-saving, and reverting back.

I run a website, so all of this is done remotely, I do not have access to the servers directly.
On my prior host, everything on the DB worked just fine. Had it optimized and running pretty good for the site by adding indexes, etc.
Then I moved to my new faster server (new host) and at first everything seemed to be just fine. However, some users started complaining about speed in spots.
Sure enough when I checked a given page -- WHAM... the page took about 14 seconds to load. Not exactly fast. :)
So I checked to make sure the indexes copied over and sure enough they did. But it was still slow, even in Query Analyzer/MSE.
So I decided to rerun my view script... on a lark... just to see if that affected something. And sure enough it did. The page started running at 1 second or less. OK, I thought, the view just got corrupted or something.
All was fine until the next night when it happened again. I had added 12 new rows to the table (I do this nightly) and it seemed that adding the new rows slowed down the system. Until the view was rebuilt. With that done again, it's worked fine.
But each night now I have to rerun that view.
What gives??? Is there a DB setting or something causing views/indexes to not be maintained?
The prior server was 2000 or 2003. The new one is 2005.
Again, I cannot get access to the box itself except through Management Studio. The host's tech support group is less than useless, treating everyone as incompetent before they help you.
Any hints or solutions would be a big help!

I'm trying to CAST an integer to a varchar and I keep getting e+006 in my result set. The reason I need to do this is so that I can combine 2 columns to return a string.
Here is my table:
incomeBracket | lowIncome(int) | highIncome(int)
-----------------------------------------------
1 1000001 5000000
2 5000001 10000000
Here is my query:
SELECT CAST(incomeLow AS varchar) + ' - ' + CAST(incomeHigh AS varchar) AS incomeRange
FROM IncomeBracket_Currency
How can I get my result to look like this:
1000001 - 5000000
5000001 - 10000000
Instead of what it is returning now:
1e+006 - 5e+006
5e+006 - 1e+007
The query works fine for values that have a character length of 6 and less.
Thanks in advance.

I was developing a data-driven website but I got this 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)
(I have Sql server 2005 also downloaded before)
Please help me cause any website that has data can not be executed even the quick start tutorial that ships with the ASP.NET 2.0
What should I do?

Hello and thanks for taking a moment to read this message.I have two colums from which I am taking values. One of which(a bit field), i am running a CASE statement against it to get SQL Server to return a string. The other is just a simple varchar column. My SELECT statement for the columns look like this:
SELECT Case tblDisplayProfile.Approved When 0 then 'Not Approved' when 1 then 'Approved' else 'Not looked at' END AS Approved, tblDisplayProfile.DisplayProfileDesc
These statements do return me something. Now what I want to do is combine (concantenate) the two fields. This is where I have problems. Any suggestions would be greatly appreciated.

Why does ado.net produce this error when I kow for a fact that there are no connections to any sql server 2005 database involved - this could and probbaly has had people off looking at the wrong connection strings in their web.configs.
Note:- The connection string we have is to a sql 200 db I just wanted to make that clear.
CheersGegor

Hi, I moved a SQL 2000 DB to a SQL 2005 server. When I run my .NET 1.1 or 3.5 website to call a stored procedure it returns the wrong results.The SQL stored proc runs fine when I excute it within SQL Manager but gives a different result when called via .NET The funny thing is I have 3 SQL servers 2000 , 2005 , and another 2005. The same data on each of the databases and the same website. Two of the databases work but the second 2005 database my production server decrements the dates some how. The funny thing is the stroed proc is not returning dates as such but a varchar of the name of the day that's getting decremented. My stored proc is SELECT
Case datepart(dw, DT_DATE)
When 2 Then 'Mon'
When 3 Then 'Tue'
When 4 Then 'Wed'
When 5 Then 'Thu'
When 6 Then 'Fri' End AS [WeekDay],
Sum(VL_HOURS) as Total
FROM ...
WHERE ....
GROUP BY datepart(dw, DT_DATE) and My c# .net code is "SqlHelper.ExecuteReader( connectionstring, storedproc, paramaeters);"using MS.ApplicationBlocksWhat happens that from sql, and 2 of my websites is when week day = 4 it returns "Wed" However on my Production server it returns "Tue" ???

i have a form which takes in a lot of input...one of them is a date field..am passing all the values to the stored proc and inserting into a table from there...pretty simple...however when the user does not enter any value in the field...its errors out as...
String was not recognized as a valid DateTime.
heres the code in asp.net
myCommand.Parameters.Add(New SqlParameter("@cusbday",SqlDbType.datetime))
myCommand.Parameters("@cusbday").Value = trim(bday.text)
the field is optional....in my stored proc i am setting a default value too
....@cusbday Datetime =NULL,...
i also xplicitly set it to null through code
if @cusbday is null set @cusbday=null
how else do i resolve this...

When I run the command:
exec master..xp_cmdshell 'NET USE'
from the analyzer the box responds there are no entries in the list.
After that, I run the command:
exec master..xp_cmdshell 'NET USE Z: /DELETE'
after which the box responds with a "network connection could not be found."
and that's all okay.
The weird thing is:
exec master..xp_cmdshell 'NET USE Z: \MACHINESHARENAME'
results in a "The local device name is already in use.".
The machine in this particular case is the box itself. I have no problem accessing other disks on other systems. I can see the share using the view command. There's no maximum on the share itself and I can connect to the share using another sql box with the same user.
I don't know why it won't budge, worked before like a charm. After six months or so it just stopped. Anyone seen/solved this behaviour?
thanx,

I have a datetime field with a value of '-28049-03-16 10:01:16.267' in SQl Server 2000. I haven't a clue how or why this value was entered as I did not design or write the database. However, I do have the task of writing a DTS package to export the data to Access. The problem is that the DTS fails when it tries to export the record with the above value into an Access table with a Date/Time field. I thought I could get round this by using a UDF to say if the date equals this value then make it null:
RETURNS DateTime
As
BEGIN
DECLARE @CheckDate varChar(300)
SET @CheckDate = CONVERT(varChar(300),@Date)
IF (@CheckDate = '-28049-03-16 10:01:16.267')
BEGIN
SET @Date = Null
END
RETURN (@Date)
END
However when I use the UDF it gives me the following error:
Server: Msg 542, Level 16, State 1, Procedure UDFn_CheckDate, Line 23
An invalid datetime value was encountered. Value exceeds the year 9999.
I have tried many variations of Convert, Cast etc. but still can't get it to work.
Anybody got any ideas???

Hello,
I'm now converting my queries from Access db to SQL Server db and I'm new with SP only.
I have a big query that is building from 1 or 2 sub-queries with "TOP x" (x is a variable in ASP).
SP can't be used with an outside variable for "SELECT TOP x.." so I tried to send the sub-query as a variable to the SP
but it refer it as a string and not a code so I can't run this sub-query in the SP.
Example:
CREATE PROCEDURE usp_test
@subSQL varchar(200)
AS
SELECT id FROM tbl WHERE id IN (@subSQL) ORDER BY id DESC
GO
----------------
exec usp_test 'SELECT TOP 15 id FROM tbl2'
What's wrong here? Am I working in a wrong method? :(
Thanks for the helpers,

INSERT INTO Contact_Info (First,Last,Age) VALUES ('Alex','Strait',19)
Now it seems basic, but there in one more field that you're not supposed to specifiy a value in the SQL, its an int IDENTITY datatype field called num_id. Now this SQL works if it doesnt have the num_id field. But heres the error is gives me, I have never seen it before

have a dts package that is run by a scheduled job which was runningsuccessfully for several months and suddenly stopped working.The dts package does the following: Truncates the table, does a datapump from a specific excel file to a table on sql server, deletes theexcel file. The job does the following:Step 1: Look to see if a file exists and if so, run the dts package. Onsuccess of this step the job goes to step 2.Step2: Looks to see if any files still exist after the first stepStep3: Failure notification. To be triggered on failure of step 1 or2.The owner of the job is the Account that is used to run theSQLServiceAgent and in the SysAdmin server role.The owner of the job is also in the SysAdmin server role.Both the accounts are Windows Accounts.The job runs at schedule time, finds the file, and runs the dtspackage. The first part of the dts package runs successfully - Thetable is cleared. However it is not doing the data pump part. Thereare no failure notifications. The job then goes to step two and sendsa message that the file still exists. The dts task is set to output anerror file which is not being updated, which tells that the task is notexecuted. If the dts package is run manually, then the package runssuccessfully.Any help would be appreciated.ThanksKR

I'm seeing some strange behavior from a stored procedure of mine. It essentially grabs a bunch of rows using a fairly simple JOIN....here's the from statement:
Code Snippet
FROM Payment PY (NOLOCK)
JOIN (SELECT DISTINCT
PY.AccountPaymentId,
ROW_NUMBER() OVER(ORDER BY PY.AccountPaymentId ASC) AS RowNum
FROM Payment PY (NOLOCK)) AS SQ
ON (SQ.AccountPaymentId = PY.AccountPaymentId)
INNER JOIN Payee PE ON PE.PayeeId = PY.PayeeId INNER JOIN
Party PT ON PE.PartyId = PT.PartyId INNER JOIN
Distribution DS ON PY.DistributionId = DS.DistributionId LEFT OUTER JOIN
Account AC ON DS.AccountId = AC.AccountId INNER JOIN
clm CM ON PE.clm_no = cm.clm_no LEFT OUTER JOIN
PartyAddress PA ON PY.PartyAddressId = PA.PartyAddressId AND
PT.PartyId = PA.PartyId
WHERE RowNum BETWEEN (((@Page * @PageSize) - @PageSize) + 1) AND ((@Page * @PageSize) - @PageSize) + @PageSize
and ((@PayeeName IS NULL) OR (PT.[Name] LIKE '%' + @PayeeName + '%'))
AND ((@AccountId IS NULL) OR (AC.AccountId = @AccountId))
AND ((@DistributionId IS NULL) OR (DS.DistributionId = @DistributionId))
AND ((@PaymentDate IS NULL) OR (DATEADD(day, DATEDIFF(day, 0, PY.PaymentDate), 0) = DATEADD(day, DATEDIFF(day, 0, @PaymentDate), 0))) -- Ignores the time
AND ((@PaymentNumber IS NULL) OR (PY.AccountPaymentId = @PaymentNumber))
AND ((@IsReconciled IS NULL) OR (PY.ReconciledInd = @IsReconciled))
AND ((@AmountIssued IS NULL) OR (PY.PaymentAmount = @AmountIssued))
AND ((@AmountPaid IS NULL) OR (PY.AccountPaidAmount = @AmountPaid))
AND ((@IssueStatus IS NULL) OR (PY.PaymentStatusEnumItemId = @IssueStatus))
AND ((@AccountStatus IS NULL) OR (PY.AccountStatusEnumItemId = @AccountStatus))
AND ((@IsReissued IS NULL) OR (PY.ReissuedInd = @IsReissued))
ORDER BY AccountPaymentID ASC
When I pass a 1 for the @IsReconciled parameter, I get the right number of rows back - 9779. But when I pass a 0 (zero), i get no rows back, although there are 222 rows which satisfy the condition.
Is there somethig I'm overlooking (I don't think I am...)? I don't know whay 1 works and 0 wouldn't...
FYI - the @IsReconciled parameter is set to NULL at the outset of the procedure -
@IsReconciled Bit = Null

Hi, I hope someone can help me with a weird problem I'm having. Towards the end of last week a number of users started reporting problems with one of our legacy applications. The application is written in VB6 connecting via ADO to a SQL 7 database. I managed to trace the error to a piece of inline SQL (shock!horror!) in a DLL that hasn't been changed since 2002, it occurs on the adodb recordset open and generates the error "could not complete cursor operation because the table schema changed after the cursor was declared" although nothing has changed on the database. It does not always happen, it depends on the contents of the strOrganisationIDs and the order of the numbers, although the same combination of numbers will generate the error every time! Initially there were certain users who were not having the error, but they have all gradually 'caught up'! There were some windows updates rolled out about the same time the errors started occuring, but un-installing them makes no difference. Here is a snippet of the code:-
Dim rsRecordSet As ADODB.Recordset
Dim strOrganisationIDs As String
strOrganisationIDs = "(111974,21986,0)"
strSQL = "SELECT o.organisation_id, o.name, o.town, o.county," & _
" o.country, o.key_customer, i.industry_sector," & _
"(SELECT Name FROM SODA_User WHERE User_Id = o.User_ID) as Name1," & _
"(SELECT Name FROM SODA_User WHERE User_ID = o.Assignee) AS Name2," & _
"o.registered_on_web " & _
" FROM Organisation o, Industry_Sector i WHERE o.Sector_ID = i.Sector_ID" & _
" AND Organisation_Id IN " & strOrganisationIDs & _
"ORDER BY o.Search_Name"
rsRecordset.open strSQL
I have managed to find a way around the error - I removed the spaces in front of the o.country, don't know why they were there, and they shouldn't cause the error - in fact they are there on the occasions it works, it seems to be the combination of spaces and certain numbers in the strOrganisationIDs . It sounds stupid and i've been pulling my hair out looking for a reason, as have several colleagues. I don't want to have to roll out the fix as it will be quite messy and affects a lot of users, although i may have to - but what I really want to know is why it has happened. I hope someone can shed some light on this, if any other info is required, let me know.

I have an int field in my custom data transform component, it's increased by 1 each time the data flow is executed, following is the code snippet I used:
Code Snippet
// fields used
bool isIncreased = false;
int field = 0;
// in Validate() method, after all validation passes:
if (!isIncreased)
{
field++;
isIncreased = true;
}
// in Cleanup() method:
isIncreased = false;
But each time I open the SSIS project in Business Intelligence Development Studio or change the ConnectionManager, the int field will be increased twice, and after that, each execution of the data flow will only increase the field by 1(which is correct). Does anyone encountered this problem before? I don't understand why it's increased twice in the situations I described.

Hi
Quite recently we have moved ourdatabase from SQL 6.5 to SQL2k. Since then we are experiencing very rare but extremely weird problems -- typically they are look like at one point zero appears instead of valid value. So far I have caught 4 such cases.
Here is the configuration:
- access -- through DBLib (ntwdblib.dll v2000.80.2039.0)
- connection string is DBMSSOCN,address,port
- server/client is Win2003 Server SP1 (server and client are different boxes)
- 2-processor systems with HT enabled
Case #1:
we have a C appliation that recalculates some data and updates two different tables simultaneously with almost the same set of data. It looks like this:
// prepare three data structures...// send data to DBswInsFxSumPlTable(pData, 3, pDbProc);swInsFxTradeExpoTable(pData, 3, pDbProc);
every function looks like:
for ( usCount=0; usCount<3; usCount++ ) { sprintf ( szQuery+strlen(szQuery), "exec sp_swFxedrq_Add_fx_sum_pl " "'%s', '%s', '%s', " "%f, %f, %f, %f ", pData[usCount].szPcId, pData[usCount].szCcyPairId, pData[usCount].szCcyLen, pData[usCount].rfNpvTodPl, pData[usCount].rfMtdPl, pData[usCount].rfNomPos, pData[usCount].rfShaPipHdg ); } fReturn = imExecMultiQuery (pDbproc, szQuery);
(no buffer overruns happen). The only difference between them is the name of called procedure and set of parameters. Both stored procedures are simple inserts, both tables are truncated beforehand. imExecMultiQuery is equivalent to:
dbcancel( dbproc ); dbfcmd ( dbproc, "%s", pszQuery ); dbsqlexec ( dbproc ) while ( dbresults ( dbproc ) != NO_MORE_RESULTS ) dbcanquery(dbproc);
(error handling is omitted for clarity). Problem: rfNomPos is different in only one row in resulting tables. I could not believe my eyes, I have checked extract from transaction log:
"INSERT","pc_id","ccy_pair_id","ccy_code_len","npv_tod_pl","mtd_pl","nom_nop","sha_plp_hdg""INSERTED","CRINST"," FJD ","3","0","0","0","0""INSERT","pc_id","ccy_pair_id","npv_tod_pl","mtd_pl","nom_nop","sha_plp_hdg","usd_eq_nop""INSERTED","CRINST","FJD ","0","0","-1.38099e+008","0","-7.92688e+007"
Red-marked values should be the same, I simply can't see any way for them to be different (except of bugs in ntwdblib.dll or SQL2k). Table and stored procedure uses type float, C code uses DBFLT8. Repeated execution produces correct results.
Case #2:
we have SQR report running every day (this is script language for report generation). It uses ODBC to connect to DB. It simply reads the table and dumps all values to text file. One row has value 0 instead of correct value. Happened only once, repeated calls produced correct results. No comments, I simply dropped my jaw when I saw it. We have zillions of SQR scripts running every day, we never had such problem before. I have checked this specific row -- nobody was touching it for ages.
Bad thing that this happens randomly in various parts of our (quite big) system, and every time we find the 'magic' place after costly and time consuming reconciliation process. Every time (whether it is reading or writing) we have similar behavior -- one column's value was replaced by 0.
I do really appreciate any suggestions, because I ran out of ideas. I do suspect bug in ntwdblib.dll related to multithreading. It is impossible to reproduce it so far... I'll try to get most fresh ntwdblib.dll, if it won't help -- I'll try one shipped with SQL6.5.
Bye.
Sincerely yours, Michael.
P.S. Sorry for font size -- looks like forum is buggy too... It looks fine in editor

hey all, i have a weird authentication error.i have two servers, both running sql server 2005. one is on my workstation the other is on my dev server. i backed up my workstation database and restored it on the dev server. my workstation is xp and my server win2k3. i'm developing an asp.net 2.0 app that talks to my sql server using windows auth. on my workstation my website runs under the ASPNET account, IUSER_COMPUTERNAME and i had that account setup in sql on my workstation in the main security folder, then again in the db security folder the name of it was [ASPNET LOGIN]. each sproc had EXEC permission for [ASPNET LOGIN].when i restored it over to my win2k3 box i deleted that login from the database and revoked it on all the sprocs. i then setup another account for the application and set my website to use that account. i couldn't use the original account because of the group it was in, blah blah blah, not important. the thing is, i got rid of all instances of that ASPNET LOGIN account and i'm running the website under a new account, and some of the stored procedures work, but some of them i get the error "Cannot find the user 'ASPNET LOGIN', because it does not exist or you do not have permission." which is crazy, because i've gotten rid of all references to that. it's not anywhere i see in the database, not in either security/users folder, it's not on any of the stored procedures. and it's NOWHERE in the website. not in IIS or code. furthermore some of the stored procedures work. as far as i can tell, the ones that are not called from my custom MemberShipProvider are working. so i went back to my database on my workstation, revoked exec permission on the sprocs, deleted the login from the db and then from the sql server instance, backed it up again, restored on my server and i'm still getting this issue.where can that ASPNET LOGIN be hiding? i restarted too thinking maybe it was cached somewhere. this is my connection string that the entire app uses: "Server=[serverName]; Database=[dbName]; Trusted_Connection=true;"my web.config is using <identity impersonate="true"/> and my website is running under the account i created.any ideas? i've been battling this for half a day.and why would it only happen with the membership provider? it's using the same connection string the rest of the app is.

HiWe have an intranet portal site, using IIS 6, .NET 2.0 & SQL2005.One page is searching matched results in several tables and giving hints to the user using AJAX, IIS may send query to SQL pretty often. Normally it is very fast (<2s) to get the result and no problem. But occassionally someone (two different users in one week recently) might get the timeout (45s set in web.config) problem consistently while other users could get the result at the same time using the same query. The same user, same PC could run the same page correctly in another duplicated developing portal site during the probelm. It implies the problem is not in theclient side. This problem is gone automatically after a while (maybe half a day or one day, not sure yet).We do not use the window's authentication to access SQL2005, i.e., a common account is used; we do not find any abnormal on IIS server and SQL 2005 server when this problem happens.Any help/suggestion is highly appreciated.Thanks,WYW

I have built a DTS package in SQL Server 2000 to Delete all rows from a table and then import from another table. I have scheduled it run twice a day and everytime it runs, it does not delete anything but imports all the records from another table. So when its done, I have twice the number of records in my final table. Then I go back to the server and execute the package manually and it works perfect. It deletes all and then imports new. I have enabled package logging and it shows both the steps executed perfectly (even when it executes on scheduled time).
What can be the problem?
Thanks,
Bullpit

Hello,
I've set up a basic login page that grabs some data from sql server. I've set up an sql server user for the connection and it all works fine.... until now that is... I get an "System.Data.SqlClient.SqlException: SQL Server does not exist or access denied." error..
Here's the weird thing though - I'm storing my connection string in web.config. If I open up web.config and re-save it, my login system works again - for a while anyway. Then it goes back to not working. When you save a web.config file, is it compiled in any sort of way? because when I do save it and run my web page, there's that sort of delay the first time round like there is when you update an aspx page or a dll. ? Anyway - it's as if that process sorts out my problem but only for a an hour or so and then the problem happens again.
I'm not making any changes to the web.config, just re-saving it. And everything else works fine, for a while at least, then the sql error happens.
Any ideas?
Thanks.

Hi, I just installed SQL Server 2005 EE. After installed it, I took a
look at the program. However, I found out that SQL Server 2005 EE
doesn't any program that you can create your database on. There nothing
like Ms. Access where you can run the program to create access database
file. SQL Server 2005 EE doesn't have something like that so that I
will have to create the database file under Visual Studio 2005
applications such as VWD or VB.
Is this just me or is that the way SQL Server 2005 EE is?

I have an application which is a SQL Server 7 back end with VB 6 SP5 front end.
For some of my users, when the VB code calls a particular stored procedure, it causes VB to die without executing the stored procedure. I am connecting via ADO.
If I execute the same stored procedure via Query Analyzer on the same machines it works perfectly.
The same code also works perfectly on all the development machines.
The error only occurs for a particular stored procedure. Other stored procedures execute perfectly on the users' machines.
Any ideas?????

I have a weird problem!
I have a database which takes up 12.5Gb of disk space yet when I drop all the objects out of it, it says that I still have 9.5 Gb of disk taken up by the database!
The database itself is nothing special. There are a couple of inefficient tables (char rather than varchar etc) and one that contains a column of datatype "image" but other than that it is pretty good.
Can anyone help?

Does anyone know why the following script won`t work unless I am already in the pubs database?
EXEC("USE pubs")
EXEC("SELECT * FROM authors")
By the way, I get this error message
Msg 208, Level 16, State 1
Invalid object name `authors`.
which would seem to indicate that (I am in the master database why I ran this script)
the EXEC("USE pubs") did not work. The weird thing is that I took this script right
from the MS SQL Server Online Books.
