Creating A Script Component Using SSIS Object Model
Jan 2, 2006
I had a SSIS Package which was developed on Beta Version Of SSIS, Now We have Standard Edition Of SSIS(Sql2k5) Installed.
In the Package we have One Flat file Source, One Script Component and A Sql Server as Target, We are programaticaly creating the package, Now When we open this Package in the Designer and Try to Run We get this error
"The script component is configured to pre-compile the script, but binary code is not found. Please visit the IDE in Script Component Editor by clicking Design Script button to cause binary code to be generated. "
Now when we just open the Script Designer and close it, The package runs.
I found the Error description at this link
http://msdn2.microsoft.com/en-us/library/microsoft.sqlserver.dts.runtime.hresults.dts_e_binarycodenotfound.aspx
but could not find any help on this.
Same thing use to work on Beta version now it is now working.
From my understanding the problem is that in beta version, the script use to run at runtime, Now what they have done is that they generate a compiled code out of script and run.
My problem is that since i am using C# code to generate the package, How Will I Create a Binary Code out of Script.
I need to create RDF files dynamically. As one example, I need to output a report that contains an OLAP table from an MDX query and will need to generate the RDL that represents the table on the fly. (Binding to a data source with any built-in control will not even come close to solving the problem. The actual requirements are extremely complex.)
In short... Rather than outputting the RDL XML the hard way is there an object model I can use to construct an RDL document with? Even if it's a bindhind-the-scenese, not-supported library?
Can anyone point me to some sample source codes or any articles that describes how I can programmatically create a package which will import data from a flatfile (csv) to Sql server database.
I know there is some example that describes exporting data from sql server to flatfiles. Anyway I have failed to accomplish my goal by following those examples.
If anyone have a code snippet to do that please help me with that.
I've ran into trouble while creating a rather simple transformation script component (one input, one output). The only thing it has to do is test the values coming from it's input rows and set the values of the output rows according to some rules; something like:
Code Block
Public Overrides Sub InputBrowser_ProcessInputRow(ByVal Row As InputBrowserBuffer)
If Row.UserAgent.Contains("MSIE") Then 'test input Row.BrowserName = "Internet Explorer" 'set output End If
End Sub
This raises an "Object reference not set to an instance of an object." exception. Commenting out the input (Row.UserAgent) solves the exception, but I actually do need to test the contents of the input row (and by leaving only the output manipulation, the script won't reach it's end, the components remain yellow). What can I do about this?
i have some code in a script task component which is meant to find a cell in an excel sheet and assign a variable to its value in the script component. I receive an error that the object is not set in instance of object. below is the code which i tried to simplify to find the error, but it is still occurring. any help would be appreciated. thank you
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!
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)
Does any body have experience in capturing DTS step error information through VB Script.
When I run following code , the code in the IF loop is executed but I get 0 as the error number. Please note that stp_sql points to an Execute SQL task and the execute SQL task is failing and this script is executed on completion ( not success) of the Execute SQL task.
If stp_sql.ExecutionStatus = DTSStepExecStat_Completed And _ stp_sql.ExecutionResult = DTSStepExecResult_Failure Then
In visual studio 2005, I create a new Integration Services Project. It tries to create the first package by default "Package.dtsx". The "Package.dtsx[Design]" tab displays
Microsoft Visual Studio is unable to load this document
Object reference not set to an instance of an object
I try to create new SSIS package or edit an existing one (from tutorial), I get the same error in the SSIS graphical user interface tab.
If I create an Active Script like this : function Main() Dim fso Dim a Set fso = CreateObject("Scripting.FileSystemObject") Set a = fso.CreateTextFile("c:est.txt") a.WriteLine("This is a test") a.Close end Function
I got an error ErrorCOde: 0 ErrorSource : VBScriptENgineError Error Description : ActiveX Component can't create object : CreateObject
Hi,Facts:I created a database to support an application that tracks events ondifferent objects. The two main tables are tbl_Object andtbl_EventLog. Each table has unique ID and on the tbl_EventLog thereis FK for a record in the tbl_Object. The events are inserted all thetime for the same or different objects from the tbl_Object. There areabout 600,000 objects in the tbl_Object and 1,500,000 (and growing)events in tbl_EventLog.Question:The user often wants to know what the last event was for a specificobject.What is the best way of retrieving the last event?Should I simply do a max(eventdatetime) on a specific object? orShould I add a LastEventID column to tbl_Object and update it everytime a new event is inserted? or any other way to implement it?I chose the second method because I didn't think it made sense searchthe event table everytime the user wants to know the last event, but Iwanted to know what the experts thought.Please let me know what you think.Thank you,Oran Levin
Hi, I'm pretty sure the answer to this is "no" but thought I'd ask anyway. Is there any way of mimicing the /Validate & /WarnAsError options of dtexec if executing a package using the object model?
If not, should I request it in the interests of consistency?

If I use the example from SQL Server BOL (http://msdn2.microsoft.com/en-us/library/ms135917.aspx), and make a new package for the sample in the same project, the sample works. The only thing that I can see that is significantly different between my code and the sample is that my DataReaderDestination has a lot more data in it, but here's the relevant code:
string dtexecArgs;
string dataReaderName;
DtsConnection dtsConnection;
DtsCommand dtsCommand; //IDbCommand
IDataReader dtsDataReader;
DataTable dtsTable;
dtexecArgs = @"/FILE ""C:Documents and Settings heinMy DocumentsVisual Studio 2005ProjectsCA3DataImportToolML3000_IntegrationProjectPackage.dtsx"" ";
dataReaderName = "DataReaderDest";
dtsConnection = new DtsConnection();
dtsConnection.ConnectionString = dtexecArgs;
dtsConnection.Open();
dtsCommand = new DtsCommand(dtsConnection);
dtsCommand.CommandText = dataReaderName;
dtsDataReader = dtsCommand.ExecuteReader(CommandBehavior.Default); // EXCEPTION HERE
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).
I have a script component that contains a script similar to that shown below;
Public Sub Main()
Dim sqlConn As New SqlConnection("Server=myserver;Database=mydb;Trusted_Connection=True;")
Dim SQLStmt As String
SQLStmt = "select top 10 CountID from mytable"
Dim sqlComm As New SqlCommand(SQLStmt, sqlConn)
sqlConn.Open()
Dim r As SqlDataReader = sqlComm.ExecuteReader() While r.Read()
Dim MyValue As Integer
If r("CountID") IsNot DBNull.Value Then
MyValue = CInt(r("CountID "))
' HERE I WANT TO WRITE MyValue TO A PACKAGE VARIABLE AS A ROW
End If
End While
r.Close() sqlConn.Close()
Dts.TaskResult = Dts.Results.Success
End Sub
Once i have a value assigned to MyValue, I want to write this as a row to a variable (DATATYPE Object Value VALUE System.Object) in the package which will be an ADO Recordset Destination that i can then loop through later.
At work, we have a rather large VB project that uses MSSQL as the back end. This program was used to gather employee data and statistics. The author has since quit and I'm trying to add some functionality to the program. Unfortunately, there is no documentation on the db and there are about 80 tables. Is there any way to create a chart/Erwin Model of some sort that would show the primary keys/relationships between the tables? Thanks!
in my report model project, i'm able to successfully create and deploy a report model based on a data source view that is in turn based on a table object in my data store.
but if i try to create a report model that's based on a a data source view that is in turn based on a view in my data store, well then, the report model that gets created comes up blank - i.e. shows no objects.
What gives? Is it not possible to create a report based on a view? that can't be right!
I have been looking at implementing a tabular model based on an OLTP database that's not dimensional. I know that this is possible but during my proof of concept I have encountered numerous problems ...
The things that I have run into are: After setting up the relationships I have found that measures filter context don't propagate along the relationships as I would expect. if the measure is coming from a target table and not a source then an ALL member is returned ( as in multi dimensional when a dimension isn't related to a measure group). Given the lay out of an OLTP database this will be hard to avoid.
One thing I have done to try an mitigate the above problem is to combine the tables used for measures in a view and using that in the source to connect to the rest of the tables. however due to the tables being of different grains this has then created duplication in some of the keys and measures. so the keys cant be used in relationships and the measures aren't accurate.
Are these things other people have come across? or should I give up the ghost and just recommend using dimensional models for the source? is tabular just geared towards a DW the same as multidimensional?
I made a Java application to pre-process portuguese texts (stopwords, stemming, BOW creating, etc.)
I want to transform this application on a Integration Service component. I understand I will have to code this new component from zero. But I have no idea on how to start.
I'm reading and testing several tutorials on Integration Services that came with the SQL Server install package but none of them has clues on developing new components. These tutorials seams more focused on demostrate the (awesome) capabilities of Integration Services.
Is there any tutorials on how to implement new components to Integration Services ?
Hi I am currently trying to write a custom transform componet in c# that will take a row of data, perform a look-up via an external system, then if there is a match then send the data from the extranel system down macth ouptut (which will have different columns to the input) and drop the data that was read, else send the data down the unmacthed output which will be the same as the input.
So I would like to write a synchrons transform becuase I don't need read all the rows from the input buffer before I started processing, also I wish have millions of rows load in memory.
Can this be done? also does any have explame code of how to do this? becuse I can't see how to send data down the match output buffer, as this will have the lookup results data which will have diffent columns to the input data and how disgard the input data as well.
Does anyone have any examples of programmatically creating a Transformation Script Component (or Source/Destination) in the dataflow? I have been able to create other Transforms for the dataflow like Derived Column, Sort, etc. but for some reason the Script Component doesn't seem to work the same way.
I have done it as below trying many ways to get the componentClassId including the AssemblyQualifiedname & the GUID as well. No matter, what I do, when it hits the ProvideComponentProperties, it get Exception from HRESULT: 0xC0048021
Does anyone know how to create a Source Script Component programmatically. I can only seem to create a Transformation Script Component. I have this:
PipeLineWrapper.IDTSComponentMetaData90 sourceComponent = ((dataflowTask as TaskHost).InnerObject as PipeLineWrapper.MainPipe).ComponentMetaDataCollection.New();
In MS Visual Studio, when creating a new Report Model Project, after defining a datasource to an Oracle database (and successfully testing it), and a simple datasource view (1 table), when I click "Run" in Report Model Wizard, I receive the following error: "ORA-02179: valid options: ISOLATION LEVEL { SERIALIZABLE | READ COMMITTED }"
It does not appear that one can create Report Models from an Oracle database (since the SQL being used to query the Oracle database cannot be edited and contains syntax errors?). Is this the case?
Hi, I would like to demonstrate mining temporary models in an ASP.NET application.
Creating, trainning, predicating actions are all witten at C# codes as follows:
Code Snippet
using (AdomdCommand cmd = new AdomdCommand()) { // Build temporary mining model cmd.Connection = asConn; cmd.CommandText = "CREATE SESSION MINING MODEL " + modelName + " (" + "HCVS_MemberId Text KEY," + "HCVS_MeasureDate DATE KEY TIME, " + "SysPressure LONG CONTINUOUS PREDICT, " + "DiaPressure LONG CONTINUOUS PREDICT," + "Pluse LONG CONTINUOUS PREDICT" + ") " + "USING Microsoft_Time_Series(Missing_Value_Substitution='Mean' ) "; // Periodicity_Hint = '{12}' cmd.ExecuteNonQuery();
// Train Data cmd.CommandText = "INSERT INTO " + modelName + " (HCVS_MemberId, HCVS_MeasureDate, SysPressure, DiaPressure, Pluse) " + "OPENQUERY([Healthcare], " + " 'SELECT HCVS_MemberId, HCVS_MeasureDate, SysPressure,DiaPressure,Pluse" + " FROM v_VitalSignForecast WHERE HCVS_MemberId=''" + id + "'' AND HCVS_MeasureDate>=''" + from.ToShortDateString() + "'' AND HCVS_MeasureDate<=''" + to.ToShortDateString() +"'' ')";
cmd.ExecuteNonQuery(); // Predict upon the Train Data. In addition, the standard deviation of each predicated value is retrieved cmd.CommandText = "SELECT FLATTENED " + "( SELECT *, " + " SysPressure + PredictStdev(SysPressure) AS [SysPressure_PlusStdev], " + " SysPressure - PredictStdev(SysPressure) AS [SysPressure_MinusStdev] " + "FROM PredictTimeSeries(SysPressure, " + fDays + ") AS SysTable " + ") " + "FROM " + modelName ;
AdomdDataAdapter adapter = new AdomdDataAdapter(cmd);
DataSet sysDS = new DataSet(); adapter.Fill(sysDS); The problem is that I do not know how to configure my Analysis Service Server to let ASP.NET account can utilize it. And ASP.NET account in trun impersonates the account who is authorized to use Healthcare DB in the Openquery. Please give a help. Thanks a lot.
