Help With Invalid Destination Component.

Sep 24, 2007

I am creating and running a package programmatically. I have the source component set up fine, and the destination component seems good, but when the package is run, it gets the error message: "Excel destination failed validation and returned validation status "VS_NEEDSNEWMETADATA" ". This would lead me to believe that I need a ReinitializeMetaData() call, but I already have that (see below). How do I fix this? Thanks for your help.



' Create and configure an OLE DB destination.

Dim conDest As ConnectionManager = package.Connections.Add("Excel")

conDest.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _

Dts.Variables("User::gsExcelFile").Value.ToString & ";Extended Properties=""Excel 8.0;HDR=YES"""

conDest.Name = "Excel File"

conDest.Description = "Excel File"

Dim destination As IDTSComponentMetaData90 = dataFlowTask.ComponentMetaDataCollection.New

destination.ComponentClassID = "DTSAdapter.ExcelDestination"

' Create the design-time instance of the destination.

Dim destDesignTime As CManagedComponentWrapper = destination.Instantiate

' The ProvideComponentProperties method creates a default input.

destDesignTime.ProvideComponentProperties()

destination.RuntimeConnectionCollection(0).ConnectionManagerID = conDest.ID

destination.RuntimeConnectionCollection(0).ConnectionManager = DtsConvert.ToConnectionManager90(conDest)

destDesignTime.SetComponentProperty("AccessMode", 0)

destDesignTime.SetComponentProperty("OpenRowset", Dts.Variables("User::gsSheetName").Value.ToString)

destDesignTime.AcquireConnections(Nothing)

destDesignTime.ReinitializeMetaData()

destDesignTime.ReleaseConnections()



' Create the path from source to destination.

Dim path As IDTSPath90 = dataFlowTask.PathCollection.New

path.AttachPathAndPropagateNotifications(source.OutputCollection(0), _

destination.InputCollection(0))

' Get the destination's default input and virtual input.

Dim input As IDTSInput90 = destination.InputCollection(0)

OLE DB Destination Component

Feb 6, 2007

when loading the transformed data into OLE DB destination, there is no options to truncate destination table first. Have to insert a middle step to run script to truncate the destination table first.

I'm very confused. We even has the options of keeping or deleting the data in destination table in SQL2000 DTS package. Why we don't have this option in SQL2005??

How To Set Sheetname On An Excel Destination Component ?

Sep 21, 2007

Hello, I am trying to create a simple package programmatically. I am following the examples in the BOL, and from some advice here. I am getting stuck at creating an Excel Destination and setting its sheetname. Everything works fine, including setting the output Excel filename. I get a runtime exception when I try to set the sheetname via SetComponentProperty. Is there another way, or am I doing something wrong? Thanks for any info you may have.

Create A Table And Then Using It As OLE DB Destination Component

Apr 12, 2007

I want to do the following in a package:



Create a table at the beginning of a package (using a ExecuteSQLTask component) and then use the created table as a OLE DB destination component, later on the package.



Is this possible in SSIS?



The problem I run into is that I have to point the OLE DB destination component to a table and set up mappings, however as the table does not exist until the package is running, it does not seem to be possible.



I've looked at:

http://blogs.conchango.com/jamiethomson/archive/2006/11/19/SSIS_3A00_-Using-temporary-tables.aspx



Which is slightly similar to what I want, but the table I create would not be a temp tables, and I need to set up mappings and I don't see how this is possible.



Thanks

Invalid Destination Path When Trying To Create Distribution Database

Jun 6, 2007

Hello. I am attempting to add a distribution database to an instance of SQL Server on my local PC. I am using SQL 2005 Developer Edition. I am able to set the instance up as a distributor using the following command:



exec sp_adddistributor @distributor = N'computernameinstancename'



I use the following command to create the distribution database:



exec sp_adddistributiondb @database = N'distribution', @data_folder = N'C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLData',

@data_file_size = 4, @log_folder = N'C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLData',



I get the following error when executing that command:



Msg 14430, Level 16, State 1, Procedure sp_adddistributiondb, Line 214

Invalid destination path C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLData.



It's not due to permissions on that particular folder. I have tried using other folders, all with the same results. Also, I am an Administrator on the PC, so I have full permissions. I have tried running the SQL Server services as myself and Local System. Same results both times. Co-workers with apparently the same setup are able to create the distribution database without a problem.



Has anybody had this type of problem?



Thanks,

Evan

Write To Excel Destination Component With Specified Range

Apr 24, 2008

I have an SSIS package that produces an Excel output file say File1
The Excel output file is created from a previous script task by copying a standard excel template to File1
after the copy, File1 has the disclaimer, legend etc... and a header row at row 10.
So data rows should only start at row 11.

I was googling and found that people who read Excel file using an Excel source component have been successful reading
from a range by the use of the OPENROWSET property. It is said to set this property to Sheet1$A5-B999
to start reading from row 5.

I tried to set the OPENROWSET property to be Sheet1$A11-B999 but am getting an error "Check that object exists"
(Sheet1 does exist) So I guess it is the range that has an improper syntax or something else is wrong.

Please advise. Thanks

How Do I Programatically Fail My Custom Destination Component?

Nov 8, 2006

I am writing a custom dataflow destination that writes data to a named pipe server running in an external process. At runtime, in PreExecute, I check to see if the pipe exists. If it does not exist I want to be able to fail the component and gracefully complete execution of my package.

Question is, how do I do this? If I make a call to ComponentMetaData.FireError() that will only create an OnError event and not actually stop the execution. So, how to I halt the execution of my component and return the error message?

Thanks,

The Data Flow's Default Destination Component

Dec 10, 2007

Is there a default destination component used when a new data flow is created? The reason I ask is simply curiosity. I have an xml file with 2 pieces of data: item A and item B. A should simply get copied out of the file. B should undergo a quick transform. I set up an XML source such that two columns are mapped correctly to the XML source data of A and B. I set up my data transform task as well. So, if I leave those two components on the .dtsx page with no other components, then will there be a default data flow destination already created? ...OR, do you always have to have a destination component?

Thanks for the input. I am just curious.

How Do I Order Columns In My Custom Destination Component?

Nov 17, 2006

Here is the situation. I have created a package that takes 50 columns from a comma delimited flat file. I then validate and clean the data. Next I add two columns that were not in the original source file. These two columns need to be in the 5th and 9th column position when the file is then re-written to a text file. How do i get those two columns to write out in the desired order? Any ideas?

Selecting Connection In Custom Destination Component UI

Feb 24, 2006

Hi there,

I am writing a Custom Destination component with a custom UI. The UI contains a combo box which contains the connection names of type €œFLATFILE€?. I also have provided a button which would create a new connection of type €œFLATFILE€? by making a call to CreateConnection method of IDtsConnectionService.
The combo box gets properly updated showing the connections of type €œFLATFILE€? but on clicking on the new Connection button the application hangs up.
Am I missing something or is there some other way to do it?

The function are the events handlers which are called by the UI.





void form_GetConnections(object sender, AvailableColumnsArgs args)
{
Debug.Assert(this.ServiceProvider != null, "Service Provider not valid.");

this.ClearErrors();

try
{
IDtsConnectionService connectionService = (IDtsConnectionService)this.ServiceProvider.GetService(typeof(IDtsConnectionService));

if (connectionService != null)
{
ArrayList temp_Connections =
connectionService.GetConnectionsOfType("FLATFILE");

args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count];
for (int i = 0; i < temp_Connections.Count; i++)
{
ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections;
args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection);
}

}
}
catch (Exception ex)
{
this.ReportErrors(ex);
}
}

void form_GetNewConnection(object sender, AvailableColumnsArgs args)
{
Debug.Assert(this.ServiceProvider != null, "Service Provider not valid.");

this.ClearErrors();

try
{
IDtsConnectionService connectionService = (IDtsConnectionService)this.ServiceProvider.GetService(typeof(IDtsConnectionService));

if (connectionService != null)
{
connectionService.CreateConnection("FLATFILE");

ArrayList temp_Connections =
connectionService.GetConnectionsOfType("FLATFILE");

args.AvailableColumns = new AvailableColumnElement[temp_Connections.Count];
for (int i = 0; i < temp_Connections.Count; i++)
{
ConnectionManager runtimeConnection = (ConnectionManager)temp_Connections;
args.AvailableColumns.AvailableColumn = new DataFlowElement(runtimeConnection.Name, runtimeConnection);
}

}
}
catch (Exception ex)
{
this.ReportErrors(ex);
}
}

Has anyone else run into this?

I am running
SQL 2005 9.0.1399 and VS 2005 8.0.50727.42 (RTM.50727.4200) on Windows Server 2003 Enterprise Edition SP1.
Any suggestions would be welcome.

The code sample is an extension to the RemoveDuplicates sample (Dec 2005) which comes along with the SQL Server.

TIA,
Robinson

SSIS And SQL Server Destination And Invalid Data For Type Numeric.

Oct 11, 2007

We have an SSIS package that reads in a tab delimited file and throughs the data into a SQL Server 2005 table. The package worked fine on the test files but when we recieved the production files we are getting the error message:

Invalid data for type "numeric".


Needless to say this is not very discriptive. I ran a trace on the DB durning the call and its doing a bulk insert

BULK INSERT [dbo].[FNIAllAppData]
FROM 'GlobalDTSQLIMPORT 00000000000015b800000000009fbd88'
WITH (DATAFILETYPE = 'DTS_Buffers', CODEPAGE = 'RAW', CHECK_CONSTRAINTS, TABLOCK)


When I changed the Data Flow Destination off to OLE DB Destination the error does not occure and all records are loaded successfully.

Any suggestions or help would be appreciated. Thanks.

Performance Issue With Custom Data Destination Component

Feb 12, 2008

Hi,
All the examples I've seen for creating custom data destinations (scripts or components) show that in the ProcessInput method you need to iterate through each record and execute a commit for each row. Here's a sample from http://forums.microsoft.com/msdn/showpost.aspx?siteid=1&postid=70469



Public Overrides Sub MyAddressInput_ProcessInputRow(ByVal Row As MyAddressInputBuffer)
With sqlCmd
.Parameters("@addressid").Value = Row.AddressID
.Parameters("@city").Value = Row.City
.ExecuteNonQuery()
End With
End Sub

This works for me but is extremely slow when processing lots of rows. Has anyone come across a better/faster example for committing rows to a database when creating a custom data destination component? I was thinking about using the ADO.NET batch update. Any thoughts on this or other approaches?

Thanks,

Mike Fulkerson

Custom Destination Component Logging - Wrote 0 Rows

Mar 17, 2006

I wrote a custom destination component. Everything works fine, except there is a logging message that is displayed that I cannot get rid of or correct. Here is the end of the output of a package containing my component:

Information: 0x40043009 at Data Flow Task, DTS.Pipeline: Cleanup phase is beginning.
Information: 0x0 at Data Flow Task, MyDestination: Inserted 40315 rows into C: empfile.txt
Information: 0x4004300B at Data Flow Task, DTS.Pipeline: "component "MyDestination" (9)" wrote 0 rows.
SSIS package "Package.dtsx" finished: Success.

I inserted a custom information message that contains the correct number of rows written by the component. I would like to either get rid of the last message "... wrote 0 rows", or figure out what to set to put the correct number of rows into that message.

This message seems to happen in the Cleanup phase. It appears whether I override the Cleanup method of the Pipeline component and do nothing, or not. Any ideas?

public override void Cleanup()

{

ComponentMetaData.FireInformation(0, ComponentMetaData.Name,

"Inserted " + m_rowCount.ToString() + " rows into " + m_fileName,

"", 0, ref m_cancel);

base.Cleanup(); // or not

}

Script Destination Component Code Sample Here That Creates A Csv Or Xml File

Jul 11, 2006

After much work and thanks to all of you who helped on this here is a code sample that can be adapted. From the dataflow task add an OLEDB source component, a row count component and finally a Script Destination Component.

On the Script Destination Component rename the Input node of the imports and outputs tree view to "ParsedInput"

The readonly User: variables that start with gs can be read in the PreExecute method

The readwrite User: variable giSuccessCount can only be used in the post execute task because it is populated by the Row Count Component which is the previous object in the Dataflow

The xml code is adapted from an idea in Donald Farmers book

enjoy

Excel Destination Data Flow Component Shows No Sheet Name Or Output Column Names For Mappings

Mar 8, 2008



I have a data flow that consists of

OLE DB source which calls a stored proc that returns a result set

data conversion

Excel destination
I am in design mode in Business Intelligence studio. My excel destination (with an Excel Connection) shows no sheet name though I have an execute SQL task before the data flow to create the excel table called SHEET1. Needless to say, there are no output columns visible to do any mappings. I did go to the ExcelConnection to set the OpenRowset Property to SHEET1 but it seems to have no effect.

I can do the export in SQL Server Management studio and that works fine, but it is basic and does not meet my requirements. I have to customize the package to allow dynamic Excel filenames based on account names and have to split my result set into multiple excel sheets because excel 2003 has a max of 65536 rows per sheet. Also when I use the export wizard, I have the source as a table and eventually the source has to be a stored proc with input parms.

What am I missing or doing wrong? Thanks in advance

Error: The ProcessInput Method On Component OLE DB Destination (513) Failed With Error Code 0xC0202009

Mar 22, 2007

I'm trying to create a simple Data transfermation. I have a flat file that came of a unix server.. it's 177 bytes wide.. thought it was 175, but when I created the flat file connector, I could see some extra characters on the end.



My output is going to be an excel spreadsheet, I only want two columns from the input. I created an oledb jet 4.0 connection. and followed instructions from here :

to create my datafow.



On my first attempt to dataflow, I ran into unicode errors and had to do this:



ran into a problem with unicode errors. went to the source for the flat file. for the output column in question changed to Unicode string [DT_WSTR].



When I run , here are the errors I get:

Hi,

I have a package which reads an Access file from a folder. My connection manager to this file is .NET providers for OledbMicrosoft Jet 4.0 OLE DB Provider.

Package works from my computer. But when I execute it on the server as a SQL Agent job, I get







The component metadata for "component "DataReader Source" (1) could not be upgraded to the newer version of the component. The PerformUpgrade method failed.  

I copied the mdb file to a folder on the server which my packages have no problem reading data from.

My packages run under the same domain account as defined in proxies.

Appreciate a help.

SQLDescribeParam With Subselect: Invalid Parameter Number/Invalid Descriptor Index

Apr 21, 2008

Hello,

I've got the following query:

SELECT zA."ID" AS fA_A
, zA."TEXT" AS fA_B
, (
SELECT COUNT(zC."ID")
FROM Test."Booking" AS zC
) AS fA_E
FROM Test."Stack" AS zA
WHERE zA."ID" = ?

With this query I call:
- SQLPrepare -> SQL_SUCCESS=0
- SQLNumParams -> SQL_SUCCESS=0, pcpar = 1
- SQLDescribeParam( 1 ) -> SQL_ERROR=-1, [Microsoft][ODBC SQL Server Driver]Invalid parameter number", "[Microsoft][ODBC SQL Server Driver]Invalid Descriptor Index"

Is there a problem with this calling sequence or this query? Or is this a problem of SQL Server?

Use Of A SSIS Variable Of Type “Object� Inside Script Component And Task Component

Mar 16, 2007

In a Data Flow, I have the necessity to use a SSIS variable of type €œObject€? inside Script Component and assign to it the content of 'n' variables of string type.
On exiting from the script the variable of type object should contain something like in the following lines:
AAAAAAAAAAAAAAAAAAAAAAAAAAAAA
BBBBBBBBBBBBBBBBBBBBBBBBBBBBB
CCCCCCCCCCCCCCCCCCCCCCCCCCCCC
DDDDDDDDDDDDDDDDDDDDDDDDDDDDD
€¦€¦€¦€¦€¦€¦€¦.
€¦€¦€¦€¦€¦€¦€¦.
On exiting from the data flow I will use the variable of type Object in a Script Task, by reading each element in a cyclic fashion.
Is there anyone who have experienced something like this? Could anyone provide any example of that?
Thanks in advance!

A Custom Component For Use As A VIEW In SSIS- Is It Possible To Create One MERGE Like Component With More Than 2 Inputs

Aug 13, 2007

Hi all
I'm into a project which uses a lot of views for joining 2 or more tables. Using the MERGE component in SSIS will be a huge effort coz it only has 2 inputs and I gotta SORT the input too.
Isnt it possible to have a VIEW like component that joins more than 2 tables and DOESNT need sorting??
(I've thought about creating views in database engine but it breaks my data floe in SSIS and is'nt a practical solution)

Reference To Preceeding Component From Custom Dataflow Transformation Component

Mar 30, 2006

I am writing a custom dataflow transformation component and I need to get the name of the preceeding component.

I have been trying to find a way to get a reference to the Package object, MainPipe object or IDTSPath90 object (connecting to the IDTSInput90 of my component) from my component because I think from there I can get to the information I want.

Serious Script Component Bug - Clears Out All Code Inside Component

Nov 27, 2007



No idea where this bug crept in from. Have been using SSIS for 1.5 years now without hitting this problem.

I had a script component opening an XML document and parsing it using XPATH. I added some code that uses StreamReader / Streamwriter (closing one stream before starting the other). The code works without issue in my C# app.

And it ran without issue 2-3 times in SSIS. Then suddenly after running my package again, the script component says it completes successfully, yet nothing happens. I set a breakpoint on the first line of code - it never hits it. I add a msgbox as the first line of code - and it never displays.

I then close my package / exit out of ssis ... and then re-open it. When i open my script component, all of my code is GONE. All references that I added are gone.

I tried adding the streamreader/writer process to a dll I created from my c# app ... and added the DLL to the package -- same result.

I can reproduce this on 2 different computers.

Anyone experience this problem ? Any idea how to stop it ? Or debug it ?


Here is a slimmed down code sample of what causes the error :


Public Class ScriptMain
Public Sub Main()
Try
Dim xmlDoc As New XmlDocument
xmlDoc.Load("c:ulkasync_86281519_20070628045850225_4.xml")
MsgBox("xmlLoaded") --this doesn't display once the package starts "acting up"
Catch ex As Exception
MsgBox(ex.Message)
UpdateXML("c:ulkasync_86281519_20070628045850225_4.xml", ex.Message)
End Try
Dts.TaskResult = Dts.Results.Success
End Sub
Private Sub UpdateXML(ByVal fileName As String, ByVal message As String)
Try
Dim invalidChar As String = message.Trim().Substring(message.Trim().IndexOf("0x"), 4)
Dim rd As StreamReader = New StreamReader(fileName)
Dim xml As String = rd.ReadToEnd()
Xml = Xml.Replace(invalidChar, String.Empty)
xml = xml.Replace("", String.Empty)
xml = xml.Replace("<![CDATA[<![CDATA[", "<![CDATA[")
xml = xml.Replace("]]>]]>", "]]>")
MsgBox("replaced")
rd.Close()
Dim wr As StreamWriter = New StreamWriter(fileName)
wr.Write(xml)
wr.Close()
Dim xdoc As XmlDocument = New XmlDocument()
xdoc.Load(fileName)
Catch ex As Exception
UpdateXML(fileName, ex.Message)
End Try
End Sub
End Class

OLE DB DESTINATION And SQL Server Destination

Jul 4, 2007

Hey All:



I was totally confused.

When designing the SSIS dataflow part, firstly , i tried SQL Server Destination because my target server is a sql server.

then execute the task with failure.

Then i tried to use OLE DB DESTINATION instead of SQL Server Destination.

This Dataflow worked.



i can not figour out why.

By the way , i used the connection is OLE DB.And i choosed OLE DB source as the datasource cuz i can not find SQL server datasource.



Who can tell me some reasons for this?

Any ideas....

Invalid Value For Key 'attachdbfilename'.

Nov 8, 2006

HI,
 We upgraded to SQL Server 2005 Standard Edition for our ASP.NET 2.0 website.  We were using SQL Server Express 2005.  That worked fine.  Now we are unable to connect to the database.  I have googled, but I just cann't figure out what is going on.  Any help is appreciated.  Here is the 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
In our firewall sqlbrowser.exe and sqlservr.exe are allowed.
Thanks Matt

Invalid Connection

Jun 19, 2008

When trying to connect to a remote SQL 2005 Express Server, I get this error message:  [DBNETLIB][ConnectionOpen (ParseConnectParams()).]Invalid connection.
 I can remotely connect to the server with the same username and password using osql in command and I can also connect to the server remotely with SQL Server Management Studio installed on this machine.
 Here is my connection string:
 Provider=SQLOLEDB.1;Password=password;Persist Security Info=True;User ID=uid;Initial Catalog=EBM;Data Source=xxx.xxx.xxx.xxxSQLEXPRESS;Use Encryption for Data=False
 The same connection string works if connecting locally, via changing the ip address to the machine name:
Provider=SQLOLEDB.1;Password=password;Persist Security Info=True;User ID=uid;Initial Catalog=EBM;Data Source=machinenameSQLEXPRESS;Use Encryption for Data=False
 
Any help would be appreciated.

Invalid Column Name

Aug 19, 2004

Hi the following SP that causes an error.



CREATE PROCEDURE GetInfo
(
@MinPriceint=0,
@MaxPriceint=9999999999,
@TypeHomenvarchar(50)=NULL,
@Locationnvarchar(100)=NULL

)
AS

Declare @strSql nvarchar(255)
Set @strSql="Select * from table WHERE "
Set @strSql=@strSql + 'Price BETWEEN ' + CONVERT(nvarchar(20),@MinPrice) + ' and ' + CONVERT(nvarchar(20),@MaxPrice )

If @TypeHome != "No Preference"
Set @strSql=@strSql + ' and Type = ''' + @TypeHome+ ''''

If @Location != "No Preference"
Set @strSql=@strSql + ' and City = ''' + @Location+ ''''

Set @strSql=@strSql + ' and IDX = ''Y'' ORDER BY Price'
Exec(@strSql)
GO



The Error I get is:
"Error 207: Invalide Column Name 'Select * from table WHERE'
Invalid Column Name 'No Preference'
Invalid Column Name 'No Preference'

I have checked the table and the columns do exist, spelled correctly and caps are all the same. Also, this same SP in another table works just fine.

What is causing this error?

Thanks in advance!

Invalid Connection

Mar 30, 2005

Hey everyone, hope you all can help me with this problem. 
We have a remotely hosted website, but we have a SQL server in our company (powers our instore portal).  I have set up our router so that i can connect to remote desktop and sql server.  I can connect to the remote desktop and i can connect to the sql server with query analyzer.  On our local site i can set up a connection to look at sqlserver.underpargolfutah.org and it works fine, everything goes well.
Now here is the problem.  On the hosted site i have set up the following
web.config >
<appSettings>
      <add key="sql_dsn" value="server=************.underpargolfutah.org;database=online;uid=sa;pwd=*******" />
</appSettings>
default.aspx >
Public Class shopDB   'publicly declare typical stuff for connections   Public conn As SqlConnection   Public cmd As SqlCommand   Public reader As SqlDataReader   Public dsn As String = ConfigurationSettings.AppSettings("sql_dsn").ToString   Public Function getBaseSelectionsByType(ByVal type)   'declare the connection   conn = New SqlConnection(dsn)   'declare command   cmd = New SqlCommand("SELECT * FROM category", conn)   'open the connection   conn.Open()   'grab data   reader = cmd.ExecuteReader(CommandBehavior.CloseConnection)   Return reader   End Function
End Class
This should all work but i get the following error
[SqlException: Invalid connection.]   System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction) +474   System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction) +372   System.Data.SqlClient.SqlConnection.Open() +384   v3.shopDB.shopDB.getBaseSelectionsByType(Object type) in shopDB.vb:21   v3.shop_default.Page_Load(Object sender, EventArgs e) in default.aspx.vb:32   System.Web.UI.Control.OnLoad(EventArgs e) +67   System.Web.UI.Control.LoadRecursive() +35   System.Web.UI.Page.ProcessRequestMain() +742Any ideas? i am stumped.
Thanks in advance-Darren
