I am on a learning project where I need to take Inputs to the Script Component from an OLE DB Source. Then I am supposed to be able to access these input columns in my Script. My Script code is in VB.NET.
My questions is:
1) How do I access these input variables in my script?
2)How to assign outputs to the output columns which will go to two separate OLE DB Destinations?
Thanks,

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)
Hi,
How can I set a variable value in a Script Component?
This syntax does not work:
Dts.Variables("myVariable").Value
Pls help.
Thanks
I have a set of comma separated variables in a Script Component list. I want to access them in Script code and use them to build string in the code.
View 9 Replies View RelatedHello, I am trying to configure a Script Component as a data source. Although this should be a simple exercise, I am running into a problem.
My control flow contains a Foreach Loop with a file iterator. The Directory Expression of the Foreach Loop Editor is supplied by an expression mapped to a package level variable called inputdirectory. The FileNameRetrieval Expression is mapped to a package scoped variable called filename.
My data flow is encapsulated by the Foreach Loop, and contains a Script Component as Source for the Data Flow Source, and a Flat File for the Data Flow Destination. The contents of the Script Designer are as follows:
Code Block
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Pipeline.Wrapper
Imports Microsoft.SqlServer.Dts.Runtime.Wrapper
Imports System.IO
Public Class ScriptMain
Inherits UserComponent
Dim thisFileDate As Date
Dim thisFileName As String
Dim thisFilePath As String
Public Overrides Sub CreateNewOutputRows()
thisFileName = ReadOnlyVariables("filename").Value.ToString()
thisFilePath = ReadOnlyVariables("inputdirectory").Value.ToString()
thisFileDate = File.GetCreationTime(thisFilePath & "" & thisFileName)
FileSpecBuffer.AddRow()
FileSpecBuffer.FileName = thisFileName
FileSpecBuffer.FullPath = thisFilePath & "" & thisFileName
FileSpecBuffer.CreateDate = thisFileDate
End Sub
End Class
When I debug the package, I get the following error:
The collection of variables locked for read access is not available at this point.
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponent.get_ReadOnlyVariables()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.ScriptMain.CreateNewOutputRows()
at ScriptComponent_67311120e6eb4162a3ea1f70847f04de.UserComponent.PrimeOutput(Int32 Outputs, Int32[] OutputIDs, PipelineBuffer[] Buffers)
at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.PrimeOutput(Int32 outputs, Int32[] outputIDs, PipelineBuffer[] buffers)
My googlefu fails me at reconciling this. I have read various posts about changing the line ReadOnlyVariables("filename").Value to ReadWriteVariables("filename").Value, and handling the buffer assignment in PostExecute. The problem is that all examples shown are either for Script Component as Destination or Script Component as Transformation. I have tried playing with the Custom Properties in the Script Commponent set the ReadOnlyVariables and ReadWriteVariables, using a PreExecute method, a PostExecute method, all with different errors returning. I'm at a loss here. Could anybody provide me with a simple working example so that I can correctly populate my output buffer in the context of Script Component as Source?
I fully understand that I could just run a Script Task Using System.IO.Directory, and System.IO.File, but I really want to make this package work in the manner I've described. Any help would be appreciated.
Thanks,

I have been building a custom component with the default GUI. I want to have all the input fields selected to be passed through to outputs without having to explicitly check each one in the GUI. Is there some method or property to set on the input to do this?
View 3 Replies View RelatedI have a Data Flow Task. I have one "OLE DB Source" which gets my data from a SQL Server Database. I have a second "OLE DB Source" which uses DATEADD to derive a date qualifier that I would like to use as a date qualifier in my subsequent Excel spreadsheet...opting to use SQL Server and DATEADD rather than messing around with VB syntax to get the previous week date qualifier.I am trying to connect the flow from one OLE DB Source to the next OLE DB Source and get the error..Component OLE DB Source has no inputs, or all of its inputs are already connected to other outputs. You may be able to edit the component to add new inputs to it.Can't I connect two completely different and independent SQL Server queries using "OLE DB Source" within my Data Flow?
Is there any way to store my derived date from my second "OLE DB Source" to a variable so that I cana then use that as my date qualifier within my Excel destination?
I've followed all of the instructions in Donald Farmer's book to create a proxy to access my SSRS web service but keep getting the following error..."Type ReportingServices2005 is not defined"....on my Dim statement for the new ReportingServices2005.dll I created and all my methods (ListSubscriptions, etc.) are similarly flagged.
My brain is not yet .Net compliant so I probably screwed this up somewhere.
I executed the following....
wsdl /language:VB http://ssrs_servername/reportserver/reportservice.asmx
sn €“k "C:Program FilesMicrosoft Visual Studio 8SDKv2.0Bin
s.snk"
vbc /target:library /out:ReportingServices2005.dll /keyfile:"C:Program FilesMicrosoft Visual Studio 8SDKv2.0Bin
s.snk" "C:Program FilesMicrosoft Visual Studio 8SDKv2.0BinReportingService.vb"
gacutil /if "C:WINDOWSMicrosoft.NETFrameworkv2.0.50727ReportingServices2005.dll"
then I added a reference to the System.Web.Services to my project (script component) and added the import statement to the script.
Is there something I'm missing??

Hi,
I am trying to make a call to a third-party web service in my SSIS package. The request has custom complex data type as the parameter. As has been pointed out in this forum before, the Web Service Task only lets you assign the outside parameter from a variable, not the internal parameters needed to create the complex data type.
To be more specific, the web service input wants a 'ContactSearchRequest' parameter. I can assign this from a variable. If I click on the 'value' field under the 'Input' section for the web service task, it shows me that the 'ContactSearchRequest' data type is made up of the following:
contactId - long
numResults - int
offset - int
passKey - string
searchParam - string
sortType - int
Unfortunately, I can't assign these internal parameters from a variable, at least not through the web service task interface.
My next thought was to create a variable of type 'object' and then set it in a script task prior to calling the web service task. However, I'm not sure exactly how to do this. How will my script know about the class definition of 'ContactSearchRequest'? Do I just create a class called 'ContactSearchRequest'?
I've used this same web service in a .NET C# project and after I imported the web service, visual studio knew all about the custom data types. How do I do something similar in SSIS?
Of course, the easiest solution would for Integration Service to allow me to set those internal parameters via variables, but we're apparently not there yet.
Any suggestions?
Thanks,

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!
I have a package variable that I set via an ExecuteSQL task. I want to reference it in a data flow script component. In the Script component I enter the variable into the ReadOnlyVariables collection, then in the script I reference it as Me.Variables.var. (E.G. counter = Me.Variables.var)
I'm getting errors when the data flow starts:
Error: 0xC0047062 at Provider, Set Surrogate Key [4261]: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> Microsoft.SqlServer.Dts.Pipeline.ReadWriteVariablesNotAvailableException: The collection of variables locked for read and write access is not available outside of PostExecute.
I have no problem referencing other variables that I have in DerivedColumn transformations. I've tried putting the variable in the ReadWriteVariables collection but I get the same error. I don't understand why this is so difficult. Please help.
Hi,
I've read the various posts and articles regarding this matter, but I seem to have problems getting to work:
In my control flow, I start by declaring a variable named "LastJobLedgerEntryID", to identify the records I need to add to the stage. From there I would like to use this variable in the source component in my dataflow, i.e.:
"SELECT [Entry No_],[Job No_],[Posting Date],[Document No_],[Type],[No_],[Description],[Quantity],[Direct Unit Cost],[Unit Cost],[Unit Price],[Chargeable],[Job Posting Group],[Global Dimension 1 Code],[Global Dimension 2 Code],[Work Type Code] FROM mytable WHERE [Entry No_] > " + @[User::LastJobLedgerEntryID]
But this fails? I should note that the variable LastJobLedgerEntryID is stored as a int32, and with the default value of 0
Could someone please help me with this?
Thanks in advance!
I have a script component in a data flow that is exhibiting some strange behavior. In the PreExecute event of the data flow, I stuff a recordset into a variable that is declared at the data flow scope. Within the data flow, I use a script component to read in the data from the recordset.
Example:
Dim olead As New Data.OleDb.OleDbDataAdapter
Dim dt1 As New System.Data.DataTable
Dim row As System.Data.DataRow
olead.Fill(dt1, Me.Variables.rsIntRateStrata)
If I display the count of the records in the data table dt1, it shows 42 rows, which is correct. Run the package, everything runs as expected. So far, so good.
Now, I set up another source/destination within the same data flow, as well as a script component between them, same as the first flow described above. Now my data flow has two parallel flows (different source & destinations). I copy the same script logic from the first flow into the second. Run the package- no errors, everything is fine... except when I inspect the data, it looks like the transformation isn't working correctly in the second script.
So I display a messagebox of each script component during run time. The first component displays 42 records, while the second displays 0 records? Same variable. Same data flow.
So I delete the first (original) flow from my data flow. Run the package again. Now the messagebox says 42.
What is happening here? Do I have to create two variables to duplicate the same recordset if I need to use it multiple times within the same data flow? Is this a bug?

I can't find anything on how to get to a global variable in a script component in the dataflow. I can get to it in a script task with no problem by using dts.variables but i doesn't appear you can do the dts variables in the script component.
I did add it to the readwrite variable list but I haven't been able to access it.
I am using one URL in script component, I want to pass the URL through variable, How can we achieve that...
I am using SSIS 2012.
I am trying to reference a package level variable in a script component (in the Code) and am unable to do so successfully. I have it listed as a ReadOnlyVariables in the custom properties of the script component, however unable to reference it in the code.
Any help will be appreciated.

Learning how to use SSIS...
I have a data flow that uses an OLEDB Source Component to read data from a table. The data access mode is SQL Command. The SQL Command is:
select lpartid, iCallNum, sql_uid_stamp
from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare)
I wanted to add additional clauses to the where clause.
The problem is that I want to add to this SQL Command the ability to have it use a package variable that at the time of the package execution uses the variable value.
The package variable is called [User::Date_BeginningYesterday]
select lpartid, iCallNum, sql_uid_stamp
from call where sql_uid_stamp not in (select sql_uid_stamp from import_callcompare) and record_modified < [User::Date_BeginningYesterday]
I have looked at various forum message and been through the BOL but seem to missing something to make this work properly.

Hello,
I have a package that has a data lfow task. this task imports data from a db2 database (using the IBM Ole DB provider fro db2) and adds it to sql server database table. This package was created on the server. then though version control (using TFS source control) I check out the package on my local machine. and when I open the package I get the foll 3 errors.
Error 1 Validation error. Import Account Num from BMGP_BDR: DTS.Pipeline: The component metadata for "component "DataReader Source" (1113)" could not be upgraded to the newer version of the component. The PerformUpgrade method failed.

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.

I'm trying to access a group of rows in a data source in my script
component (transformation). Currently im using the connection manager
in the script component, acquire the connection, and issue a query
command to get the data. This will happen on every rows being pass to
the script component from the data source. Is there a better way to
access the a group of rows from the data source?
Hi,
I have created a view. However this view needs a specific variable that a user has inputted in Access. The variable I need to pass into the first view is a DocketID..Similar to a StoreID. I then must run the second view, which also depends on the same DocketID. Finally I must run a final query that takes the result from the second view, which takes the results of the first view.
Basically, I want to pass the variable from my VBA application to the SQL statement. I have been reading, and it seems that like in VB I must declare a local variable in a DECLARE statement. Is that right?
How would I pass the variable that can be held in the VBA application ex. DocketId = 220 and pass that 220 to my SQL statement which is running is SQL 7.0. Most of the statement will be running in SQL, not the VBA application.
Hey all...I'm pretty new to SSIS packages and things are coming along nicely. My problem is accessing variables in script tasks.
I've created two variables (package scope, strings, readonly = false) - aDetailFiles and strDetailFile
Within a Foreach Loop I loop through a folder. I've added a script task and within that I try the following:
Dts.Variables("User::aDetailFiles").Value = Dts.Variables("User:trDetailFile").Value.ToString() + "|" + Dts.Variables("User::aDetailFiles").Value.ToString()
Everytime this script executes I get the following errors:
at Microsoft.SqlServer.Dts.Runtime.Variables.get_Item(Object index)
at ScriptTask_feac87c947ce4431a4fee0ba0e13631d.ScriptMain.Main() in dts://Scripts/ScriptTask_feac87c947ce4431a4fee0ba0e13631d/ScriptMain:line 25
I have searched this error message but the only thing I found was to set the ReadWrite variable property but I don't know where to set that.
Expresion property set as false also.
Any ideas? Thanks.

View 6 Replies View RelatedHi all,
i am not very experienced with the SSIS. I am just wondering if there is something like a "if-then-else"-componente like the foreach-component in SSIS.
I want to delete the values of all tables in one database. So I took a foreach-component and selected the smo-enumeration with all tables. I store the tablename in a variable and execute a sql-task with "delete table.." with the variable tablename as parameter. Now I want to delete all except one certain table. I would like to add a selection where the variable tablename is checked. If the tablename is this certain table, I don't want to execute the sql-command, else I want to excecute the delete-command.
Are there any suggestions?
Thank you very much

Hi,
I am trying to export data from SQL7 to Access using a DTS package. I want to use the global variables within the package in sql statements.
How can I do that?
I have 2 global variables set: @DID & @Rowid
When tranfering data I used the sql statement to get the data from SQL7:
Select * from Tablex where ColumnX=@DID AND ColumnY > @rowid
but when I do that I get an error: You must declare the variable @DID
Why is that, if I declared it in the global variables section????
TIA.
Hi everyone,
passing variables (values) from a form (MS Access Project) to a stored procedures in order to select records shouldn't be all that difficult. However after searching for hours and hours in various forums and discussions i'm still nowhere. I really hope someone can give me the missing hint.
OK All I whant to do is select data from the sql server via an access interface. the value entered into the access form by the user (for example the client name) should then be transferred to the stored procedure which will then return all the records of the chosen client.
The simple task of transferring this form value to the stored procedure is driving me crazy. Does anyone have an idea.
Thanx in advance

Hello,
I found one post from the past asking this question, but didn't see an answer, so I am hoping someone can shed some more light on it:
I am writing a custom log provider in C#. Is it possible give this custom log provider access to the variables collection (via a variabledispenser object)? First glance at the log provider classes would tell me that this is not possible, though I would like confirmation. Also, if I am correct in thinking it is not possible, what was the reason for leaving this out?
Thanks!
My script component defines a (DT_WSTR, 450) output column named keyword. How can I access its length within the script, instead of hard-coding 450 as a constant?
My feeble attempts to tease this out through Visual Studio got me this far:
Output0Buffer.keyword.GetType.GetProperty("Length").GetValue(
but now I'm stuck. Also, if it matters, this is an asynchronous transformation component.
Thanks!

Hi,
I've created a stand alone custom dataflow component in VB and I need to set up the connection to the Input and Output components and instantiate it. The only way I've seen this done is to create an entire package and Task then use the TaskHost wrapper object to instantiate the Mainpipe (IDTSPipline90 interface) so that you can create the IDTSPath90 interface and setup the connection to the input and output components...
After all that, all that I would like to know is whether it is possible to instantiate the mainpipe interface without creating a package programmatically? I've seen something Darren Green put in an answer to a thread, about accessing the Mainpipe interface in the UI, to the effect that you can access it through IServiceProvider using the interface IDTSPipelineEnvironmentService - I think that's it... But I'd like to know if there is a more straightforward route to instantiating and accessing the Task or data flow directly?
Thanks in advance,
Will.
I have just migrated a DTS 2000 package
as an SSIS package.
one of the features that failed to migrate, was a transformation
that , selected 2 colums of data with a stored procedure,
file name, and full path of filename,
Then the file name only was written to a txt file,
Then there was an ActiveX transformation task that used the other
column (full file path) to copy said file to another location (specified as a global str variable eg \127.0.0.1directory..etc)
Now my question is this, with SSIS script task
can i save the path name (2nd column) to a variable and then
using this variable copy the file to another location (global str variable) ?
Is there a CopyFile function like there is in ActiveX ?
And can i add this script task along with the DATA FLOW ?
because if i add it outside the DF , it will only (im assuming) copy the last line (path) into the variable...
