Data Stream And SQL
Jul 28, 2004
Hi all,
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.
Thanks.

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:
@action varchar(10),
@GLTransactionID int = NULL OUTPUT ,
@GLBatchID int = NULL ,
@GLAccountID int = NULL ,
@CurrencyID int = NULL ,
@LocalDebit decimal(28, 13) = NULL ,
@LocalCredit decimal(28, 13) = NULL ,
@BaseDebit decimal(28, 13) = NULL ,
@BaseCredit decimal(28, 13) = NULL ,
@TransID int =NULL,
@Description varchar(255) = NULL
I am calling this proc from VS.NET 2003 using the .Net SqlClient Data Povider (C#). I'm setting the values of the parameters like this:
cm.Parameters.Add("@action", "insert");
cm.Parameters.Add("@GLBatchID", _gLBatchID.DBValue);
cm.Parameters.Add("@GLAccountID", _gLAccountID.DBValue);
cm.Parameters.Add("@CurrencyID", _currencyID.DBValue);
cm.Parameters.Add("@LocalDebit", _localDebit.DBValue);
cm.Parameters.Add("@LocalCredit", _localCredit.DBValue);
cm.Parameters.Add("@BaseDebit", _baseDebit.DBValue);
cm.Parameters.Add("@BaseCredit", _baseCredit.DBValue);
cm.Parameters.Add("@TransID", _transID.DBValue);
cm.Parameters.Add("@Description", _description.DBValue);
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:
?cm.Parameters["@BaseDebit"].SqlDbType
Decimal
?cm.Parameters["@BaseDebit"].Precision
0
?cm.Parameters["@BaseDebit"].Scale
22
?cm.Parameters["@BaseDebit"].DbType
Decimal
?cm.Parameters["@BaseDebit"].Value
1000000
[System.Decimal]: 1000000
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.
Any clues or suggestions weclome.
Thanks

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.

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
insert into Event_Transactions (
OrphanedFlag
,ProcessedFlag
,ProcessedTimeStamp
,EventTimeStamp
)
values (
1
,0
,NULL
,'2004-05-07 15:15:24.000'
)
insert into Event_Transactions (
OrphanedFlag
,ProcessedFlag
,ProcessedTimeStamp
,EventTimeStamp
)
values (
0
,1
,'2004-07-08 13:04:01.513'
,'2004-07-07 16:52:08.000'
)
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.

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?
tia for any info

Hi everybody,
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.

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" )
Anyway, any idea on how to solve this?
Code Snippet
using Microsoft.Reporting.WebForms;
protected void Page_Load(object sender, EventArgs e)
{
LocalReport localReport = new LocalReport();
localReport.ReportEmbeddedResource = "Monkey.Report1.rdlc";
ReportDataSource reportDataSource = new ReportDataSource("FamilyCollection", Monkey.Family.RetrieveAll());
localReport.DataSources.Add(reportDataSource);
string reportType = "PDF";
string mimeType;
string encoding;
string fileNameExtension;
string deviceInfo =
"<DeviceInfo>" +
" <OutputFormat>PDF</OutputFormat>" +
" <PageWidth>8.5in</PageWidth>" +
" <PageHeight>11in</PageHeight>" +
" <MarginTop>0.5in</MarginTop>" +
" <MarginLeft>1in</MarginLeft>" +
" <MarginRight>1in</MarginRight>" +
" <MarginBottom>0.5in</MarginBottom>" +
"</DeviceInfo>";
Warning[] warnings;
string[] streams;
byte[] renderedBytes;
//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();

Hi,
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.

Hey Guys,
This may be easy...or it may be impossible!
I need to match a text field on zero or more characters. If available, the 'or more' characters need to be in a specific sequence.
The % wildcard doesn't quite cut it.
For instance, I need to match the name field with 'm', 'ma' or 'mar' (but no other character combinations).
Is this possible?

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'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 the following code in an SSIS package and I get the following error:

Instead of the GZipStream do I have to use some other stream class for a zip file. Please let me know.

Hi, all here,
Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,

After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.
anyone having this problem before?? hopefully you guys can help.

I have used both data readers and data adapters(with datasets) in the projects that I have worked on. I am trying to get some clarification on when I should be using which one. I think I am doing this correctly but I want to be sure I am developing good habits.
As the name might suggest, it seems like a datareader is for only reading data. I have read that the data adapter and dataset are for a disconnected architecture. Or, that they can be used for this type of set up. I have been using the data adapter and datasets when writing to a database and the datareader when reading from a database.
Is this how these should be used? Is the data reader the best choice for reading data? Am I doing this the optimal way from a performance stand point?

I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.
The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?
Is there any performance impact if we enable CDC on OLTP db?
Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?
What is the best way to implement CDC to take incremental changes for reporting.

Hi all, i got this error:
[DTS.Pipeline] Error: "component "Excel Source" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
and also this:
[Excel Source [1]] Warning: The external metadata column collection is out of synchronization with the data source columns. The column "Fiscal Week" needs to be updated in the external metadata column collection. The column "Fiscal Year" needs to be updated in the external metadata column collection. The column "1st level" needs to be added to the external metadata column collection. The column "2nd level" needs to be added to the external metadata column collection. The column "3rd level" needs to be added to the external metadata column collection. The "external metadata column "1st Level" (16745)" needs to be removed from the external metadata column collection. The "external metadata column "3rd Level" (16609)" needs to be removed from the external metadata column collection. The "external metadata column "2nd Level" (16272)" needs to be removed from the external metadata column collection.
I tried going data flow->excel connection->advanced editor for excel source-> input and output properties and tried to refresh the columns affected.
It seems that somehow the 3 columns are not read in from the source file?
ans alslo fiscal year, fiscal week is not set up up properly in my data destination?
anyone faced such errors before?
Thanks

RE: XML Data source .. Expression? Variable? Connection? Error: unable to read the XML data.
I want my XML Data source to be an expression as i will be looping through a directory of xml files.
I don't see the expression property or the connection property??

I setup this package to import data from a Sharepoint list to a SQL Server data table. The primary key of my SQL table is mapped to the Title column of my Sharepoint list. There is a possibility that duplicate values will be entered in the Title field of the Sharepoint list. So when importing data into my table via SSIS, my package always error-out when there it comes across duplicate values. how you others have managed data integrity when importing from a Sharepoint list with the Title column being mapped to the primary key of a table.
