What I'm trying to solve:
I have an application that generates SQL queries, and sometimes uses
DISTINCT where the result set has no dupe rows. In terms of database
resources, I'm trying to figure out if it's worth it to change to app to be
smart enough to not use DISTINCT where it won't serve any purpose, or
whether to let it do the DISTINCT and save added complexity to the query
building application. I.e. what is the cost of DISTINCT where there are no
dupe rows?
What I want to know:
Can someone explain how the stream aggregate operator actually goes about
doing its work?
Does this always create a temp table for sorting and discarding duplicates
(for DISTICNT)? If the answer is "no or sometimes", how does it do so in
the case where a temp table is not involved? I noticed the the estimated
I/O for this operator was zero for some queries I wrote agains pubs. Does
this mean that the optimizer believes the temp table needed will fit
in-memory and creates it in-memory? Or does the estimated I/O figure not
included disk writes for work tables?
I've read the other posts related to this issue, but I'm just REALLY confused as to whats happening in my case. Like everyone else it was working fine in SQL 2000 but now in SQL 2005 there is an issue. I'm calling a stored procedure with parameters defined like this:
When I execute the call to the stored proc I get this:
"The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 8 ("@BaseDebit"): The supplied value is not a valid instance of data type numeric. Check the source data for invalid values. An example of an invalid value is data of numeric type with scale greater than precision."
Using the VS.NET command window I then inspect that parameter to see what the heck is going on and get this:
So I set a decmial parameter to 1,000,000, that parameter in the DB is defined as decimal(28,13) so should fit no problem, but it seems the Sql data provider is confused and thinks 1,000,000 is decimal (0,22)???
I receive this error when I make a depolyment to our new server(virtual server). The report works fine in the report manager. In my application, I use RenderStream method to retrieve the images and embed in the webform. I googled it and found some people having the same issue because of the cookie, so they set 'UseSessionCookies' = false in the table ConfiurationInfo of ReportServer database. I tried this, but no luck.
Also, there is a hotfix from Microsoft http://support.microsoft.com/kb/913363. I have requested a copy, but not sure whehter it's gonna be helpful.
I am just trying to establish if there is a way that I can capture a direct data stream(feed) from another server and have it input into a table.
The scenario is - I have a PABX that is outputting a stream of data with each record being 83 characters long. Each of the fields is seperated by a space. The end of the record is distinguished by a "Line Feed". The port it is being sent to on my local machine is Port 5000.
Is this possible to do or not? I know that some of our DB guys who use oracle can do it, I would like to have this as a MSSQL database so that I can use it and manipulate it a bit further.
I dont know if this is the right place to put in this question.
The problem is
I have an application developed using VB 6.0 and SQl Server 2000. It was working fine on my machine. I had MS XP installed on my system alongwith SP1. But when i installed MS XP SP2, i got the error while saving the record. the error is "Protocol Error in TDS Stream". I went to microsoft site searcing for the resolution of this error. They gave the solution of installing MDAC 2.8 SP1. But when i install MDAC 2.8, it gives me this error "MDAC 2.8 RTM is incompatible with this version of Windows. All of its features are currently part of Windows." And since MDAC 2.8 is not installed so i can not install MDAC 2.8 SP1 also.
I have MDAC 2.5 installed on the system.
How can i resolve it. Please give a solution as soon as possible. I am in great need of it.

Hi,I have a problem which I don't entirely know how to tackle:Essentially, is it possible to query a web service (via http), usingsql server 2000, and then import that data in to the database?I have seen many posts on openxml and sql servers bulk load facilitiesbut nobody seems to mention whether you can open an http stream andread the xml in from there.Any help would be greatly appreciated.Thanks.
I have a very simple test report created in Visual Studio 2005 as an rdlc file in my dll. The rdlc file is in the dll because it is built off of the business objects. I need to be able to stream this file (i.e. not use a report viewer) to the browser.
I found code that I included below, but get an error:
The report definition for report 'Monkey.Report1' has not been specified
Yes my test namespace in my dll is named "Monkey" )
//Render the report renderedBytes = localReport.Render(reportType, deviceInfo, out mimeType, out encoding, out fileNameExtension, out streams, out warnings);
//Clear the response stream and write the bytes to the outputstream Response.Clear(); Response.ContentType = mimeType; Response.AddHeader("content-disposition", "attachment; filename=foo." + fileNameExtension); Response.BinaryWrite(renderedBytes); Response.End(); }
I have a problem with a database on our SQL 7 system . I had set away a restore from tape, but cancelled it after users complained that a different database was performing slowly . However, this has resulted in the database being marked as inaccessible when trying to access it through SQL Enterprise Manager and trying to access it through Query Analyser produces message 927 informing me that the database is in the middle of a restore . How do I remove this error and make the database accessible again??
Many thanks in advance

I am trying to enable the FileStream in SQL Server 2012 Enterprise Edition. I can successfully enable "Enable Filestream for Transact-SQL Access" but I am unable to enable "Enable Filestream for the file I/O access". Due to this I am unable to open the folder location of the filetable.
I am loading data from one server to another server using SSIS,After loading some rows i am getting the below mentioned Error.Each time i run i am getting the error in different Dataflow tasks in the package.
Error : " [OLE DB Source [199]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available.

The PrimeOutput method on OLE DB Source returned error code 0xC0202009. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.There may be error messages posted before this with more information about the failure.".IS this SSIS package Error or Network related?
before anyone even says it, i checked the collation order on everything and it's the same. i get the error when the snapshot is trying to be bulk copied to the subscriber.
i'm on sql2k sp4, server and db collations are SQL_Latin1_General_SP1_CI_AS. here's a repro. 1st, run this in a blank db:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Event_Transactions]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table [dbo].[Event_Transactions] GO
CREATE TABLE [dbo].[Event_Transactions] ( [EventTransactionId] [int] IDENTITY (1, 1) NOT NULL , [OrphanedFlag] [bit] NOT NULL , [ProcessedFlag] [bit] NOT NULL , [ProcessedTimeStamp] [datetime] NULL , [EventTimeStamp] [datetime] NOT NULL ) ON [PRIMARY] GO
CREATE CLUSTERED INDEX [EventTransactions_IDX_ProcessedOrphanedEventTimeSt amp] ON [Event_Transactions] ( [ProcessedFlag], [OrphanedFlag], [EventTimeStamp] ) ON [PRIMARY] GO
ALTER TABLE [dbo].[Event_Transactions] ADD CONSTRAINT [PK_Event_Transactions] PRIMARY KEY NONCLUSTERED ( [EventTransactionId] ) ON [PRIMARY] GO
Now, use transactional replication to replicate it to another db taking all the defaults. when the distribution agent tries to apply the snapshot, it fails with the message mentioned in the title..
Has anyone ever seen this? It's keeping us from considering MS replication for one of our major products. Thanks.

Hello all, I was trying to run a test to write a ebcdic file out with a comp - 3 number (testing this for other people) and have run into a problem writing the string out to the flat file destination. I have the following script component:
Code Block
' Microsoft SQL Server Integration Services user script component ' This is your new script component in Microsoft Visual Basic .NET ' ScriptMain is the entrypoint class for script components Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper Imports Microsoft.SqlServer.Dts.Runtime.Wrapper Public Class ScriptMain Inherits UserComponent Public Overrides Sub CreateNewOutputRows() ' ' Add rows by calling AddRow method on member variable called "Buffer" ' E.g., MyOutputBuffer.AddRow() if your output was named "My Output" ' Output0Buffer.AddRow() Dim myByteArray() As Byte = {&H12, &H34, &H56, &H7F} Output0Buffer.myByteStream = myByteArray Output0Buffer.myString = "ABCD" Output0Buffer.myString2 = "B123" myByteArray = Nothing End Sub End Class
I have added myByteStream as a DT_BYTES length 4, myString as (DT_STR, 4, 37) and myString2 as (DT_STR, 4, 37) to the output 0 buffer.
I then add a flat file destination with code set 37 (ebcdic us / canda) with the corresponding columns using fixed width.
When i place a dataviewer on the line between the two the output looks as I expect ("0x12 0x34 0x56 0x7F", "ABCD", "B123"). However, when it gets to the flat file destination it errors out with the following:
Code Block [Flat File Destination [54]] Error: Data conversion failed. The data conversion for column "myByteStream" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
If i increase the size of the byte stream (say, to 50) the error goes away but I am left with the string "1234567F" instead of the appropriate hex values. Any clues on how to go about this? I obviously don't care if it gets transferred to "readable" text as this is supposed to be a binary stream, thus the no match in target page seems superfulous but is probably what is causing the problems.
NOTE: this is relating to the following thread (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=2300539&SiteID=1) in that I am trying to determine why these people are not seeing the "UseBinaryFormat" when importing an EBCDIC file (i see this fine when i use an ftp'd file, but it auto converts to ascii) with comp-3 values. I also see the "UseBinaryFormat" when I am importing a regular EBCDIC file which I create that has no import errors with zoned decimals.
I was putting a database together (its a C# application MSSQL)  the application will handle a few hundred customers records and save  maybe a couple of thousand  word docs/images/other doc files wondered if the way to go was blob or filestream, I see the medium and larger databases seem to go for filestream but just wondered as not much mentioned about smaller dbs.I do not think  security/disk space/super fast access  will be a big issue.
I have a column that has an expression with a runningvalue in it, a "Carrying Cost" for each month. I need to create another column that aggregates the monthly Cost. I can't to do a Runningvalue on the Runingvalue. I can't even do a Sum on the Runningvalue.
I'm getting the following error from a few hosts that are querying a db in SQL Server 2005. The error has occurred while executing various queries that we would expect to return various sized result sets (from a couple rows to a couple million rows). Many hosts have never experienced the error but it is occurring fairly frequently on a couple.
using Windows Server 2003 on both the jdbc client and the DB host.
using jdbc driver from sqljdbc_1.1
netstat doesnt increment the TCP connection reset count after this error occurs.
using standard sql server authentication.

I have a table that has 4 colums (id,projectno,date,price) i want to make a select that returns the sum per project no i used this query select projectno,sum(pice) as sum from supplier group by projectno
but i want to include additional columns like id and date for the result but its giving this message: Column 'supplier.id' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
is there a better way to do so without joining the main table with the upper select query? Best Regards
Hi, I have we have a client who gives their invoices in a flat file format, we import it into a SQL Server table. Nothing is normalized – everything is repeated in every record. The fields are: customerNumberInvoice_numberPO_numberQtyDescriptionLine_numberLine_totalFreightTaxInvoice_date So an if an order has 10 line items, the header information (invoice number, PO number, ivoice date) are repeated on each of the lines I am writing a query to show the following Order number, Invoice total, Date select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice_date from invoices group by invoice_no, Invoice, customerNumber This works great - for each invoice I get the invoice number, InvoiceTotal, and Date Then I was asked to add the PO Number – this is where I can’t get it right. When I added “PO_number� to the query, I got two lines for each invoice select invoice_no, sum(line_total + freight + tax) as invoiceTotal, customerNumber, Invoice, PO_number from invoices group by invoice_no, Invoice, Sold_To_Cust_No, PO_number Please help - I need to end up with: invoice_no, invoiceTotal, customerNumber, Invoice_date and PO_number (sequence does not matter) Thanks

I have a table that is used for employee evaluations. There are six questions that are scored either 1, 2, 3, 4, or 5. I want to tally the responses on a page, but I wonder if I can do it without 35 separate calls to the database (I also want to get the average response for each question). I know I can do "SELECT COUNT(intWorkQuality) AS Qual1 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '1' " and then "SELECT COUNT(intWorkQuality) AS Qual2 FROM dbo.Summer_Project_Req WHERE intWorkQuality = '2' " and so on. But can I somehow do the aggregating at the page level, and just refer back to a datasource that uses a generic statement like "SELECT intWorkQuality, intDepend, intAnalyze, intWrite, intOral, intCompatibility FROM dbo.Summer_Project_Req"? If I can, I am not sure what type of control would be best to use or what syntax to use to write the code-behind. I would like the results to be displayed in a grid format. Thanks in advance for your help.
I was doing a SUM on my returned rows and i found that what i really want is an aggregate bitwise OR on all the returned rows. Do you know what's the function for that?
I have two tables tb1 with item and qtyOnHand and a second table tb2 with item and qtyOrdered I am trying without success to make this happen;select sum (onHand-Ordered) from (select sum (qtyOnHand) from tb1 where item = RD35 group by item) as onHand, (select sum (qtyOrdered) from tb2 where item = RD35 group by item) as OrderedI kind of gathered it would work based on this http://weblogs.asp.net/jgalloway/archive/2004/05/19/135358.aspxI have also tried this;select tb1.item from (select sum (qtyOnHand) from tb1 where item = RD35 group by item) as onHand, (select sum (qtyOrdered) from tb2 where item = RD35 group by item) as Ordered, sum (onHand-Ordered) as available from tb1 where tb1.item = RD35Any ides, there are multiple rows of each item in each table tb1 is inventory with several different locations and tb2 is an orders table.
I was told that on Oracle there's something called an Aggregate Navigator which should be capable of changing the table you're addressing in a query to another table (with aggregate data) and in this way optimize performance in a data warehousing environment.
I need to run a query to get the following result(by carrier and for each calc_date, calculate the percentage of all individuals who have rcf greater than 0.73):
carrier,calc_date,count of ind with rcf > 0.73, count of all individual, percentage of individuals with rcf's greater than 0.73.
does anyone have an idea of how to achieve that result?
