We have a strange occurrence in one of our dev Sql server. Our platform is Sql Server 2000 on SP4. Build Number is 8.00.2039
TableA
Sid int, --Non-Clustered Index
Aid int,
Uid int,
€¦..
TableB
Iid int,
Sid int, ---No foreign key constraint to TableA.Sid but logically refers to that column. --Non-Clustered Index
€¦..
Now, we are working on schema changes, now TableB looks like
TableB
Iid int,
Uid int, ---Logically refers to TableA.Uid
€¦..
Sid in TableB is dropped and a new column Uid is added.
And there is no Sid in TableB.
We have an existing SP that refers to TableB.Sid like
Create proc sp_ab
As
Select Uid from TableA where Sid = (Select Sid from TableB where Iid = @Iid)
After making the schema changes listed above, if I try to compile this SP without making any changes to the procedure, it should fail. Surprisingly it passes compilation and also retrieves data using hash joins and doing table scans on TableA avoiding index seeks. This SP used to take less than second, now takes almost 90 seconds to retrieve data. I couldn't replicate this problem with another set of objects.
If I make changes to the SP sp_ab like
Create proc sp_ab
As
Select Uid from TableA where Uid = (Select Uid from TableB where Iid = @Iid), it runs less than a second as it should.
Whats surprising is, if I do 'Select Sid from TableB where Iid = 1 ' in Query analyzer, it throws error referring to invalid column Sid in TableB but couldn't throw this error when the sql is wrapped in a SP. Everything else in the DB and in the db server seems to be ok except this.
If I query Syscolumns table, I couldn't see any references to Sid in TableB after the schema chnages and not sure why the code in SP is not caught during compilation. Any clues.
Hi I've got a sql server 2000 database that when running is runnign fine. About 9 months ago I altered one of the stored procedures and ever since then when the machine is rebooted the stored procedure is "reverted" back to the old sproc... ??? is there any way I can recrete a sproc in a job that runs every day?? why would it be doing this?
I'm using MS SQL 2000 Analisys services by using the RDC to the server. After a power breakdown I logged again to the server and the analisys services and got the error attached.
What sould I do ? I thought to restart the analisys services service but I'm afraid I'll need to process the cube again
Can any one let me know as how can I query the first occurence of a record. I need to select all distinct Order Types from a table. If there is more than one record with the same Order Type, then I need to get the first record.
Hi all,How can I get a row that has only one occurence in a table? Notthrough 'distinct' because this gets a single row that might havemultiple occurences, I want to get only rows that have only oneoccurence in the table.I tried the group by and within the having clause I placed thecount(myfield) = 1, did not work...select f1, f2, count(f2)from table1inner join table2 on table1.id = table2.fidwhere .....group by f1, f2having count(f2) = 1gives me result like this: (basically in this situation, I dont want toreturn any results)f1 f2 count(f1)--- --- -----------1 a 12 a 1any ideas sql gurus?thanks
Hi ...I have a weblog database where I want to count the occurences of atable of string values that appear in all the urls viewed.My tblWebLog as a field that contains the url ...tblWebLog.[cs-uri-stem]I have another table ... tblStrings ... that has a field [strSearch]for a string value and an integer field [intViewCount] to count theoccurence of the string in tblWebLog.[cs-uri-stem]I've been trying ...Update tblStringsSet [intViewCount] = (Select Count(*) From tblWebLog Where[cs-uri-stem] Like '%_' + tblStrings.[strSearch] + '.htm%').... but it doesn't fly and I'm stumped. Any thoughts?Cheers.
I have a table that tracks GPS records broadly speaking as followstsDATETIMEusernameVARCHAR(16)...GPS data...I want to select the most recent GPS data for each distinct user.That is, the table will have may records for a given username, but Ionly want the most recent for each one.For a single user I know I can doSELECT TOP 1 * from <table> order by ts descBut I want a set of results that effectively does this forall users, and I can't work out the necessary query/subquery Ishould be using.I'm sure I'm missing something fairly obvious, so usual newbiedisclaimers apply.--HTML-to-text and markup removal with Detaggerhttp://www.jafsoft.com/detagger/
Hi All, I want to extract a numeric value from a string. Example, in a string like - Mgmt Pack: Processor Exception Threshold >80% Every 10 Minutes. - I want to extract that number 80. Since, later I'll want this number to plot a graph.
Since this is going to be an alert pulled from OnePoint (MOM Operational Database), the number will vary, and so I cannot look for the same number. So, can anyone help me how to get this working?
Thanks a lot in advance and let me know if the question is not clear.
Hi Everyone- i woder if someone know Built in function to search the occurence of char in string in T-SQL
and iam not talking about the Index of the first occurence (e.g CHARINDEX ) but it is more generic
i want to send to the function to ask about the index the second or the third or N occurence of the char. and i wonder if it is built in for performance reasons
example getseachIndex("M|d|d","|",2)==> the result is 4
i m using sql server 2000. My problem is tht no matter what date i enter, sql server always displays it as 1900-1-1. This is happening on all columns which have been specified as datetime. Whts the problem & the solution to the problem?
I get this SQL-sever error in my application. I guess it has something to do with the declaration of namespaces? Does anyone know for sure? Thanks in advance!

I have a script that creates a database and sets up everything required for merge replication. Merge replication is pull with a single parameterized row filter based on HOST_NAME() and joins on other tables. It works perfectly. I recently decided to drop all my identity columns and use rowguid's instead.
I modified my script by only changing the primary key column definitions, basicaly I went from "[Id] [int] NOT FOR REPLICATION IDENTITY (1,1) NOT NULL PRIMARY KEY CLUSTERED" to "[Id] [uniqueidentifier] ROWGUIDCOL NOT NULL DEFAULT NEWSEQUENTIALID() PRIMARY KEY CLUSTERED".
The script still works fine. Everything is executed succesfully and even the snapshot agent finishes it's job.
But the problem is, that when I want to create a partition I get the following error:
A value for the parameter @host_name was specified, but no articles in the publication use HOST_NAME() for parameterized filtering. (.Net SqlClient Data Provider). Microsoft Sql Server, Error: 20672
If I try to synchronize a subscription then the subscription is created succesfully, but I get an error while synchronizing stating: Merge agent was unable to determine if another subscription exists for the current partition.
And yes, I do have my filters set up 100% correctly.
The funny thing is, if I create the publication via Management Studio, then I don't get that error. But if I create the publication via Management Studio, immediately afterwards generate the script for it, delete the publication and create the publication from the generated script, I get the error again
From this I have concluded that no way can the problem be in my new script... Everything is dandy fine with the server as well, because the original scipt still works flawleslly.
Does anyone have any ideas what I could try to get things working? Has anyone even gotten merge replication set up via script, while database -> uses only rowguids, hostname parameterized filter and joins? Or should I just report this as a bug to Microsoft and go back to my original script, including the identity hell?

Hi, I have a SQL Server stored procedure that gets called in the ASP.NET application. For a while it will return results quickly. After an unknown amount of time the stored procedure starts taking forever to execute. If I go into Query Analyzer and execute the same stored procedure using the exact same input parameters the results return quickly. If I then go back into the application and run the code that executes the stored procedure, the results return quickly again. So basically every time the application call to the stored procedure begins to slow, I run that stored procedure in query analyzer and then it runs fine in the application again. Has anyone else experienced anything like this or have any ideas as to why this would happen?
We've been experiencing this strange error from our SQL server for about a month now and i've tried alot of things, visited alot of websites and manufactured a few possible solutions but nothing helps! Its very frustrating. This is the error i get when i try and expand the server tree:
A connection could not be established to [OurServerName]
Reason: SQL Server does not exist or access denied.
ConnectionOpen (Connect())..
Please verify SQL Server is running and check your SQL Server registration properties by clicking on [OurServerName] node) and try again.
What really gets to me is that everything works after i restart the server. Then things will go fine for about a day or two and then the same thing again. This i causing alot of downtime for us. Can anyone please just give me a suggestion? :confused:
We have a stored proc that accepts a date and uses that date in a filter. This procedure worked fine for a couple of weeks then started hanging. Basically, this date parameter is used in a where clause.
Our workaround: when we declare a new variable, set it equal to the parameter, then use the declared variable - that fixes it. Take away the declared variable and use the parameter instead and the proc chokes. But the paremeter and the declare variable are both datetime typed. Weird.
We are worried (partly because it worked without hanging for a while) that we are experiencing a larger issue. We are reporting off a database we denormalize and populate nightly with transactional data. A poor man's warehouse if you will, staging the data in a fast reporting format with the prep done each night. This database is wiped and re-populated each night. We have been testing this process with the same source data, so we are not growing our data at all (net result at end of each night is same data as previous day).
I think the source code here is overkill, but I enclosed the proc anyway. The way it is written below, it hangs. Replace these two uses of @AsOf in the proc with @test and the procedure almost instantly returns data. There is a third use of @AsOf that doesn't affect the issue one way or the other. This line is where the replacement fixes the problem:
--Breaks Where (OpenedDt < DateAdd(day, 1, @AsOf) or ClosedDt < DateAdd(day, 1, @AsOf)) and (PlanType = @PlanType or @PlanType is null)
--Fixed Where (OpenedDt < DateAdd(day, 1, @test) or ClosedDt < DateAdd(day, 1, @test)) and (PlanType = @PlanType or @PlanType is null)
If anyone has experienced this or knows some other symptoms to check for, we are all ears. This is scaring us because otherwise we have a working system on our hands and are near a delivery point. Help would be greatly appreciated.
Here is the complete proc...
ALTER PROCEDURE [dbo].[ClaimCountsByLineOfBusiness] -- Add the parameters for the stored procedure here @AsOf datetime, @PlanType varchar(50)
AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON;
DECLARE @DataFreshness datetime Select @DataFreshness = DataFreshness From metaReportList Where StoredProcedure = 'ClaimCountsByLineOfBusiness'
If @AsOf is null SET @AsOf = Convert(datetime, Convert(varchar(10), GetDate(), 101))
DECLARE @test datetime SET @test = @AsOf
-- Insert statements for procedure here Select PolicyGroup, Lines, SUM(CASE WHEN HasPayment = 1 and OpenClosed <= 0 THEN 1 ELSE 0 END) as ClosedClaimswithPayment, SUM(CASE WHEN HasPayment = 0 and OpenClosed <= 0 THEN 1 ELSE 0 END) as ClosedClaimswithoutPayment, SUM(CASE WHEN OpenClosed > 0 THEN 1 ELSE 0 END) as ClaimsOpen, Count(ClaimSummary.ClaimNumber) as ClaimsReported, AccidentYear, ReportingYear, --Return the value of the parameters in a friendly way (if null) Convert(varchar(10), @Asof, 101) as AsOfParameter, IsNull(@PlanType, 'any value') as PlanTypeParameter, @DataFreshness as DataFreshness
FROM (Select ClaimNumber, Max(OpenedDt) as OpenedDt, HasPayment, PolicyGroup, Lines, AccidentYear, ReportingYear From dbo.factClaimSummary Where (OpenedDt < DateAdd(day, 1, @AsOf) or ClosedDt < DateAdd(day, 1, @AsOf)) and (PlanType = @PlanType or @PlanType is null) Group by ClaimNumber, HasPayment, PolicyGroup, Lines, AccidentYear, ReportingYear) as ClaimSummary
INNER JOIN
(Select ClaimNumber, SUM(CASE WHEN OpenedDt is not null THEN 1 ELSE -1 END) as OpenClosed From dbo.factClaimSummary Group by claimnumber) Status ON ClaimSummary.ClaimNumber = Status.ClaimNumber
Group by PolicyGroup, Lines, AccidentYear, ReportingYear Order by PolicyGroup, Lines END
Can anyone help me solve why my server is locking up.
We're running sql server 2005 ent on a 2 cpu dual core server. With 3gig. Once each the last couple weeks, the machine has hung and the only thing I can find that's suspicious is on the sql server log. It's below. After the excerpt is about 50 more different memory errors. As far as I know there's no ssl configured for log in, it mostly uses private lan cards for security between it and the web/application server.

I am getting a linked server connectivity errors randomly. We have a set of DTS packages to pull data from OLTP (SQL 2000) to reporting server (SQL 2005) through linked server and both instances are on same server. The process is running ok on Acceptance server, and failing on production server. It is throwing the following error randomly, and it is getting fixed for a while after restarting SQL 2000 service.
An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available.

I€™m suffering a queer behaviour when I use BIDS. Concretely, when I open a dtsx from my project (it has 10 packages) many times Sequence Container and Data Flow tasks are invisible. I mean, its lines are not visible at all whereas its titles are. I mean, what you see is just a white box€¦
Then, I€™m gonna Data Flow layer and I have to do double-clik over the tasks and are visible but on Control Flow I don€™t see how to solve.
Curiously in our development and production server such behaviour doesn€™t happen (we are accessing by mean Terminal Server from our workstations)
How odd!. Everything is fine except this.
I want to remark you that such project has been copied from the server, this is, these packages are been built on the server
I have two SQL Server Instances on two servers. One server is my webserver and database server and the other one is just a database server. i have an application that calls a stored procedure located on the webserver/database server that runs a query on the OTHER database server. I use linked tables in my first instance to make the call possible.
Everything was working just fine for months until the database server was restarted and the IP address was changed. The name of the database is the same however and my first SQL Server instance has no problems running queries on the other databases tables. However, when you try to run the application i get the following error:
Login failed for user 'sa'. Reason: Not associated with a trusted SQL Server connection
I have mixed mode authentication selected and my security uses the security context with username=sa and password=sa.
So here's the weird part.
The application will only run correctly when i manually run a SQL command from my webserver's SQL Analyzer on the linked SQL Server. however, after a few minutes, the same error comes back!! so as a temporary fix, i scheduled a dts job to run a simple query on the linked server every two minutes, so the application keeps working! It's almost as if the webserver's sql server forgot that the linked server is there, and by running a simple query in query analyer, the connection gets refreshed and everythings normal again - for about 3 minutes!
I am completely stumped by whats happeneing and appreciate any help. Thank you.
I'm a wee bit of a newbie concerning DTS and have inherited a db with a DTS containing a Copy SQL Server Objects task set to run nightly. Essentially, it does an informal backup of some core data.
Recently, I was notified that one of the tables it copies over is now empty on the Destination db. The DTS shows that it runs successfully with no errors logged, the table in question IS selected to be copied from the Source database, there IS data in the Source database table, and every other table in the Destination database is populated appropriately.
Any ideas on what would cause this one table to be empty without generating any errors?
Wondering if anyone can help with a strange exception thrown while using the SqlBulkCopy class. I am using the class to transfer records from a DataTable in memory (approx 11,000 rows) into a SQL Server 2005 table.
Initially, the WriteToServer method was timing out a la KB913177 (http://support.microsoft.com/default.aspx/kb/913177), however I downloaded the hotfix, which eliminated this issue.
Now, I get a new exception thrown, as follows:
System.Data.SqlClient.SqlException: OLE DB provider 'STREAM' for linked server '(null)' returned invalid data for column '[!BulkInsert].Power_Avg'. at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlBulkCopy.WriteToServerInternal() at System.Data.SqlClient.SqlBulkCopy.WriteRowSourceToServer(Int32 columnCount) at System.Data.SqlClient.SqlBulkCopy.WriteToServer(DataTable table, DataRowState rowState) at System.Data.SqlClient.SqlBulkCopy.WriteToServer(DataTable table)
I can't see anything wrong with the data I have. The column "Power_Avg" is of type "float". When forming the DataTable, I cast my data to float expcilitly in C#.
Other things to know:
I am using SQL Server Express (2005) This same code works fine with SQL Server 2000 (MSDE) My code makes all modifications inside a single transaction of type "Snapshot" (I have activated SNAPSHOT READ COMMITTED in the database) I have not activated MARS in the connection
A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.) (Microsoft SQL Server, Error: 233)

When I consult the error log I see:
Could not connect because the maximum number of '4' user connections has already been reached. The system administrator can use sp_configure to increase the maximum value. The connection has been closed. [CLIENT: <local machine>] 2007-01-30 04:53:14.93 Logon Error: 17809, Severity: 20, State: 3.
The log error message doesn't make any sense because there aren't 4 user connections.
After I received the error message, mgmt studio still lets me access the database make changes, but I cannot connect via my application. Any ideas? Thanks!
Hi There,I am having a strange problem with my identity column...... 1). I have a table of Products that have an identity column auto-incremented by 1. 2). I have my asp program working quite well in which the Data entry operators are adding the products into my database..... and they do not have any interface through which they can delete products........ 3). My Database is running at Web server(MS SQL Server)My problem is that when i cehcked my database.... there were around 1000 records but the auto increment number have reached to 1500. and when i checked in details then i saw that Auto number column is being skipped certain numbers..... like one entry is 1478 then the next one comes to be 1482..... and 1508 to 1516........ Its happening alot of times and it seems that SQL Server is skipping some numbers............Since it is Auto-Number so i do not have control over it through my code.... So i think the coding might not be the problem...... I have set Identity seed as well as Identity Increment both to 1.Is there any thing that you can suggest me to do??(Thanx)
we are working on a web application created in ASP & SQL 2000 environment. In the code , we have a single connectionstring to connect database. The application was running fine for the past 3 years, but all of a sudden we are getting "timeout expired" error only in someparts of the application but not on all database access. The code which raises this error is a bit large which need to look into table of 8k recs with more conditions. The same sql query took 1:01 minutes to execute in query qnqlyser. I changes the script timeout to 900secs, I herd we need to upgrade MDAC or we need to change connection timeout or we need to cahnge the code.
we cannot change the query, it is the most possible way we could get that.
