Hi,

I am using a stored procedure and places the value into a dataset.
But it prompts me an error.

And here is my code:

Dim cmd As New SqlCommand("testProc", mySqlConnection)

cmd.CommandType = CommandType.StoredProcedure
cmd.Parameters.Add("@PrdCode", SqlDbType.VarChar, 50).Value = strBonPrdCode
cmd.Parameters.Add("@keyWord", SqlDbType.VarChar, 250).Value = srchKeyword
cmd.Parameters.Add("@keyWord_Count", SqlDbType.Int).Value = Keyword_count

Dim da As New SqlDataAdapter(cmd)
Dim ds As New DataSet

PrimeOutput() And NullReferenceException Problems With DataReader Source In SSIS

Jun 20, 2006

Hi

I have an integration services script that was working ok until a recent database upgrade. When I run the script in gui debug mode it behaves as follows. The data flow reads in data from an oracle server table VALNREQ & then uses it to populate a sqlserver table (with a little manipulation of the fields in between). For some reason although it populates the destination table with the correct number of rows (& the data looks ok) it errors out with the messages listed below. The DataReader Source dataflow source box turns red & all the other boxes turn green including the destination one. I have run out of ideas ... any suggestions? Have I inadvertently changed a property without noticing? I can't see anything obvious & the input data itself looks clean enough.

Any pointers in the right direction would be great, thanks. I've been thrown in at the deep end with this s/w so I imagine there are a number of large gaps in my knowledge so apologies if there is a simple solution to this.

[DataReader Source VALNREQ [1]] Error: System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostPrimeOutput(IDTSManagedComponentWrapper90 wrapper, Int32 outputs, Int32[] outputIDs, IDTSBuffer90[] buffers, IntPtr ppBufferWirePacket)


[DTS.Pipeline] Error: The PrimeOutput method on component "DataReader Source VALNREQ" (1) returned error code 0x80004003. 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.

I'm not a developer, so I'm pretty lost why it behaves like this on one server and not the other. Checked Aspnet.config-file and they are the same. Found this

http://support.microsoft.com/?id=911816

that described that the exception handling was different between the .NET-versions, but since this works on one of the servers, it shouldn't be related, or could it? Tried changing the setting in method 2, but with the same behaviour. Any ideas?

Best regards

Can't Assign Connection Manager Object To DataReader Source

Sep 22, 2006



I'm trying to create a DataReader source object using a working ADO.NET Oracle Client connection object that exists in the connection manager.

Problem:

When I open the editor the DataReaderSrc component shows only one row under the Connection Managers tab:

Name=IDbConnection
Connection Manager=blank
Description=Managed connection manager

I cannot assign the ADO.NET connection (or any connections). I see a warning at the bottom of the Connection Managers tab:

"Not all connection managers have been set. Set all connection managers."

When I click refresh the warning message changes to:

"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."

I am prevented from removing the IDbConnection or assigning my Connection Manager object to the DataReader Source.


Thanks, -- Mike

How To Reference ADO Object Source Variable Within Script Component?

Dec 7, 2007



Hello,
I have a 'ForEach Loop Container' that does a select from a table and I use Variable Mappings to map each row set result to Package Variables in SSIS. This works fine. However, in the Data Flow, I have a Script component in which I need to access the values of those variables that have been set in the ForEach Loop Container. How do I do this?

Perhaps I'm on the wrong track but I guess I need to access the ADO Object Source variable set in the ForEach Loop Container? Through my own experimentation, I know that accessing the VariableDispenser collection only returns whatever default values that happen to be assigned to the variables in the SSIS GUI (not the values assigned during each iteration of the ForEach Loop).

Thanks,
Clive

When Using A Sqldataadapter In VS 2005 I Get The Following Error At Runtime. Object Reference Not Set To An Instance Of An Object

Dec 21, 2006

Help! I have posted this before and I had hoped that the VS2005 SP1 would help my problem. It didn't. My code is shown below.

It compiles without any errors but at runtine I receive the system error "Object reference not set to an instance of an object." The error occurs at the first line where the sqldataadapter is mentioned. I have shufflled the code and the error still occurs at first mention of the dataadapter. I have set parameters to a simple string such as "myemail." It hasn't helped. I have used the "Dim" statement as "Dim DaAuthorLogin as System.Data.SqlClient.SqlDataadapter and Dim DaAuthorLogin as New ......) at the start of the private sub generated by the event requiring the data.

Predict Query Gives 'DMPluginWrapper; Object Reference Not Set To An Instance Of An Object' Error

Mar 17, 2008



Hi,

I am trying to develop a custom algorithm. I have implemented and tested training methods, however I fail at prediction phase. When I try to run a prediction query against a model created with my algorithm I get:


Executing the query ...
Obtained object of type: Microsoft.AnalysisServices.AdomdClient.AdomdDataReader
COM error: COM error: DMPluginWrapper; Object reference not set to an instance of an object..
Execution complete


I know this is not very descriptive, but I have seen that algorith doesn't even executes my Predict(..) function (I can test this by logging to a text file)
So the problem is this, when I run prediction query DMPluginWrapper gives exception -I think- even before calling my custom method.

As I said it is not a very descriptive message but I hope I have hit a general issue.

Thanks...

VS 2005 Error 'Object Reference Not Set To An Instance Of An Object' With Integration Services Project Create Failure

Previously I had SQLServer 2000 client with the little VS tool that came with it installed. Uninstalled these prior to installing the 2005 tools (VS and SQLServer).

I'm not finding any information on corrective action for this error.

Any one have this problem and found the solution?

For the life of me I cannot figure out why i'm getting the "Object Refence Not Set To an Instance of An Object" error after I try and create a Report Services project in Business Intelligence Studio.

Does anyone have any other ideas as to how I can get rid of this annoying error and start creating some reports?

Datareader Object Throws A Non-descript Error.

Mar 4, 2008

I call the datareader using a sqlCommand that I programmatically build and it accesses the database fine.  I can use the exact SQL command that I generate and I can get a result when i run it in SQL Management Studio.  When I run the application and try to access the datareader, it throws an exception whose message is quite frustratingly, <column name>, or in this case "image_URL".  Anyone have any idea what might be causing such an ambiguous error?

Error On DataReader Source

May 21, 2008



I have a problem with DataReaderSource.
I'm trying to get data from Notes table. I created a Connection manager
and the connection was successful. The SQLCommand in "Component properties"
tab is a simple "select * from <table_name>". When I switch to the
"Column mappings" tab, only the first column from the table is displayed.
Pressing the "Reftesh" button resulst in the following error:
Error at Data Flow Task {DTS.Pipeline]: The "output column <column_name> has a length that is not valid.
The length must be between 0 and 4000.
When I go to the "Input and Output Properties" tab, the DataType for the output column is not populated
and the error message "Error in Data Flow Task [DTS.Pipeline]: The output column <column_name> had an
invalid datatype (0) set."
The DataType property is not populated at all. Changing the data type to DT_STR results in error:
"Property value is not valid". Details: Error at Data Flow Task [DataReader Source]:
The data type of output columns on the component "DataReader Source" cannot be changed".



I read on a previous post to explicitly convert field , and tried to explicitly covnert the dataype on the field
in my query (ex. select convert(varchar(50) from fieldname)

It then gives foll err:


ERROR [42000] [Lotus][ODBC Lotus Notes]Incorect syntax near ','
[Lotus][ODBC Lotus Notes]Name, constant or expression expected.



Any idea on how to resolve this?

Datareader Source Error

Oct 25, 2007

I get an error at the end of a 47 million row job when I use the datareader source. It goes through all the records and then the package fails. The error (DataReader Source [1]] Error: System.NullReferenceException: Object reference not set to an instance of an object. ) occurs at the datareader source. I suspect it's because my record set returns a null value at some point. Any ideas?

SSIS Error On DataReader Source

Feb 29, 2008

I have a package that runs every hour. It runs fine most of the time but once in a while

I get this not very helpful error message "the component 'xyz' is unable to process data" on DataReader Source component.

when i try to run it again on the same data it works fine. So i dont think it has to do with data.

Is there a way i can get more information on this error?

Hello, I get the following error when I run my package interactively.

It seems as if this error occurs when the DataReader source tries to process the received data.

SSIS Datareader ODBC Source Error

Feb 24, 2006

I am trying to import data from an ODBC source using the Datareader but have come accross a problem, can anyone help?

Whenever I try to do a 'SELECT * FROM sometable' I get the following error:

Error at Data Flow Task [DTS.Pipeline]: The output column "notes" (521) has a length that is not valid. The length must be betewwn 0 and 4000



Most of the tables we require have this field.

Is there any way to by pass this error and import the field as DT_WSTR type and convert to DT_NTEXT?

Our original DTS package (2000) worked well but we would like to move forward.



Thanks in advance.

Error When Changing The Length On DataReader Source

Nov 3, 2006

Hi,
I am trying to import data from Oracle RDB into SQL Server 2005 using SSIS. Created a ODBC data source to connect to Oracle and used DataReader Source component and ADO.net to connect to the ODBC data source.

Under the Component properties tab, the SQL Command looks something like this.

Select ID, ADDRESS, REVISED from ADDRESS

The data type for the source columns are Integer, Varchar(30) and DATE VMS.

Now when I look at the Input and Output properties window,

The External columns has the following data types.

ID - four-byte signed integer [DT_I4]
ADDRESS - Unicode string [DT_WSTR], length = 0
REVISED - database timestamp [DT_DBTIMESTAMP]

The Output columns has the following data types

ID - four-byte signed integer [DT_I4]
ADDRESS - Unicode string [DT_WSTR], length = 0
REVISED - database timestamp [DT_DBTIMESTAMP]

When I tried to change the length of the ADDRESS on the output column, I get the following error.

Error at Data Flow Task [DataReader Source [1]]: The data type of output columns on the component "DataReader Source" (1) cannot be changed.

Error at Data Flow Task [DataReader Source [1]]: System.Runtime.InteropServices.COMException (0xC020837D)
at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)
at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostSetOutputColumnDataTypeProperties(IDTSManagedComponentWrapper90 wrapper, Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)

Is this the default length for the Unicode string type. I was not able to load the ADDRESS column as it gets truncated before I load it into destination. Even if I use Derived or Data Conversion transformation, the ADDRESS is getting truncated before it reaches this transformation.

Any thoughts.

Thanks,
SK

Error Assigning Connection Mgr To Datareader Source Component

Jan 13, 2006

Synopsis:

Attempting to create a data flow task to copy data from AS/400 (DB2) to SQL2005, using an existing System DSN ODBC connection defined on the SQL2005 host.

Problem:

When adding the DataReader Source component to the package, I cannot assign the Connection Manager. Designer issues the error message:

"The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."

Editing the DataReaderSrc component shows only one row under the Connection Managers tab:

Name=IDbConnection
Connection Manager=blank
Description=Managed connection manager

The datareadersrc component editor displays the warning message: "Not all connection managers have been set. Set all connection managers.". Clicking the Refresh button causes the error message to be displayed "The runtime connection manager with the ID "" cannot be found. Verify that the connection manager collection has a connection manager with that ID."

I am prevented from assigning my Connection Manager object the DataReaderSrc.


The package already contains one Connect Manager object:

Provider: .Net Providers/Odbc Data Provider
System DSN


Test Connection operation succeeds

Any help would be appreciated.

Fraser.

Error Message: Object Reference Not Set To An Instance.........

Aug 22, 2006

I have migrated an existing ASP.net 1.1 application into ASP.net 2.0. After correcting the reported errors and warnings the application builds without any errors. I have a login page for users (AuthorLogin.aspx) that receives input from the user and checks the database to determine if the user is valid. If the user is in the database they are directed to a navigation page. The SqlDataAdapter used to access the SQL 2000 database causes the above error when I try to pass parameters to it using the input by the user. The dataadapter was added on the using the component designer for the AuthorLogin.aspx page. The parameters are the user's email address and a password. The dataadapter fills a dataset. If the dataset's rows are >0 then the user is redirected. The dataadapter and dataset are declare on the.vb code behind page as "protected with events...." Here is the code I am using.
Public Sub AuthorLoginValidate()
'use the email and password text values as parameters
DA_AuthorLogin.SelectCommand.Parameters.Item("@AuthorEmail").Value = AuthorLoginEmail.Text
DA_AuthorLogin.SelectCommand.Parameters.Item("@AuthorPassword").Value = AuthorLoginPassword.Text
MDData.Open()
DA_AuthorLogin.Fill(DS_AuthorLogin, "T_Author")
MDData.Close()
'if the database has an existing record then add session objects and redirect
If DS_AuthorLogin.T_Author.Rows.Count > 0 Then
Session.Add("AuthorAlias", DS_AuthorLogin.T_Author.Rows(0).Item("AuthorAlias"))
Session.Add("PreferredName", DS_AuthorLogin.T_Author.Rows(0).Item("PreferredName"))
Session.Add("LastName", DS_AuthorLogin.T_Author.Rows(0).Item("LastName"))
Response.Redirect("AuthorPaths.aspx")
Else : AuthorLoginNotValid.Visible = True
Exit Sub
End If
End Sub
Steps I have taken.

Reordered the parameters. Whichever parameter occurs first in the code throws the error
Set the parameters to a string instead of the user's input. The error still occurs.
Previewed the data to make sure the dataadapter and dataset are working correctly. They are.
Double-clicked the dataadapter and dataset to determine if the .vb code page will open with a new sub for the dataadapter or datatable. It does.
Declared the dataadapter explicitly at the beginning of the code. "Dim DA_AuthorLogin as new system.data.sqlclient......... You get the idea. This causes a warning that the dataadapter has not been assigned a value. I don't want to assign a value. I want to retrieve data.
I have tried to use the datasource control but this seems designed specifically for the datagrid, datalist, etc and it must be assigned a value
I have tried to use a dataset designed to use a datatableadapter and a datatable. This throws the same error.
I found a MSDN KB article that said to register the adodb file in the configured assemblies. I ran this command line as stated. It did not help.
This code worked well in my .net 1.1 application. I know other data adapters work in the application. Help please. What will work? I am about to go back to my .net 1.1 application and forget Visual Studio.net 2005 simply because I cannot access the data.
Thanks, David

DataReader Source Error - Cannot Change The Datatype, Precision Or Scale In The Output Columns

Oct 3, 2007

I have a data source that I access via odbc in a DataReader Source component in SSIS. I can access the data fine. However, I am having problems with certain fields that are numeric (specifically home prices ranging from 100,000.00 to 99,999,999.00). In the advanced editor for my data reader source under the input and output properties tab, in data reader output under the external columns and output columns, these fields for some reason default to numeric data types with a precision of 4 and a scale of zero, not large enough to hold the data that is coming in. This causes errors that make the data come in as null (after i specify to ignore the errors).

I can change the precision and scale to 18 and 4 in the external columns, but when I try to change the datatype, precision or scale in the output columns I get the following message:

Property Value is not valid.

The details are:

Error at Import DataReader Source: The data type of output columns on the component "DataReader Source" cannot be changed.
Error at DataReader Source: System.Runtime.InteropServices.COMException (0xC020837D)
at Microsoft.SqlServer.Dts.Pipeline.DataReaderSourceAdapter.SetOutputColumnDataTypeProperties(Int32 iOutputID, Int32 iOutputColumnID, DataType eDataType, Int32 iLength, Int32 iPrecision, Int32 iScale, Int32 iCodePage)

Any help is greatly appreciated.

Connecting To Database - Object Reference Not Set Error Message

Feb 11, 2005

I've got code that on my own machine (visual studio .net 2003 and iis and sql server all exist on this box) works great. I display my test page, which loads a dropdownlist on page_load. This works great on my own machine.

When I move the code to our dev environment. Web server and database servers on separate boxes. I get the error "Object reference not set to an instance of an object" when i try to open the connection to the database. I thought it had to do with permissions and I check all through sql server and everything looks great. I then thought it was the connection string. I still haven't ruled this out, but I wrote a quick vbscript app to attach to the database and try to pull a record. The vbscript worked fine. So, the code works fine on my computer, but not on the web server. The connection does work with vbscript, but through my asp.net web app I get the "object reference" error.

All code below...

ASP.NET webpage:
private void Page_Load(object sender, System.EventArgs e)
{

if( !IsPostBack )
{
// Create a command object for the query
string mySelectQuery = "select id from vw_abcd order by ID";

SqlCommand myCommand = new SqlCommand(mySelectQuery,sqlConnection1);
sqlConnection1.Open();

DropDownList1.DataSource = myCommand.ExecuteReader(CommandBehavior.CloseConnection);
DropDownList1.DataBind();
sqlConnection1.Close();

RangeValidator1.MinimumValue = "1";
RangeValidator1.MaximumValue = DropDownList1.Items.Count.ToString();
}
}

Connection string on my machine:
workstation id=wXXXXXX01;packet size=4096;user id=testuser;password=testpass;integrated security=SSPI;data source=wXXXXXX01;persist security info=False;initial catalog=TestDB"/>

Connection string on web server:
network library=DBMSSOCN;data source=xxx.xx.xxx.xxxinstance1;user id=testuser;password=testpass;initial catalog=TestDB


vbscript:
Dim connConnection, rstresultset
strConnectionString = "driver={Sql Server};server=xxx.xx.xxx.xxxinstance1;user id=testuser;password=testpass;database=TestDB"

Set connConnection = CreateObject("ADODB.Connection")

connConnection.Open strConnectionString
Set rstresultset = createobject("ADODB.Recordset")

rstresultset.ActiveConnection = connConnection

rstresultset.Open "select id, comment from testtable", connConnection

msgbox rstresultset(0)
msgbox rstresultset.Fields(0).Value



Error message and stack trace:
Object reference not set to an instance of an object.

at System.Data.SqlClient.ConnectionPool.GetConnection(Boolean& isInTransaction)
at System.Data.SqlClient.SqlConnectionPoolManager.GetPooledConnection(SqlConnectionString options, Boolean& isInTransaction)
at System.Data.SqlClient.SqlConnection.Open()
at Web2.Drilldown.Page_Load(object sender, System.EventArgs e)




Any ideas what's going on?????

Datareader Destination As Source For Other Datareader Source ?

Aug 30, 2006

HI!

as far as I know from docs and forum datareader is for .NET data in memory. So if a use a complex dataflow to build up some data and want to use this in other dataflow componens - could i use data datareader source in the fist dataflow and then use a datareader souce in the second dataflow do read the inmemoty data from fist transform to do fursther cals ?

how to pass in memory data from one dataflow to the next one (i do not want to rebuild the logic in each dataflow to build up data data ?

Is there a way to do this ? and is the datareader the proper component ? (because its the one and only inmemory i guess, utherwise i need to write to temp table and read from temp table in next step) (I have only found examples fro .NET VB or C# programms to read a datareader, but how to do this in SSIS directly in the next dataflow?

THANKS, HANNES
