Access Read Only Variables In Script Component In A Dataflow
Dec 6, 2006I 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 RelatedScript Component As Source: The Collection Of Variables Locked For Read Access Is Not Available At This Point.
Jan 17, 2008Hello, 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,

How To Access Inputs As Variables In Script Component Script In SSIS
Jan 17, 2008
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,

Using Variables In Data Flow Script Component
Jan 12, 2006I 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.
Passing Variables To Data Flow Component
Apr 27, 2006Hi,
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!
Weird Behavior Using Variables In Script Component
Mar 27, 2007I 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?

Global Variables And The Script Component In DataFlow
Apr 12, 2006I 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.

Mapping Package Variables To A SQL Query In An OLEDB Source Component
Nov 2, 2006Learning 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.
http://msdn2.microsoft.com/en-us/library/ms139904.aspx
The article, is the closest I have (what I belive) come to finding a solution. I am sure the solution is so easy that it is staring me in the face and I just don't see it. Thank you for your assistance.

Access Datasource In Script Component
May 2, 2006I'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?
Passing Variables From Access To SQL
Apr 24, 2001Hi,
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.
Access To Dts.Variables Causes Exception
Aug 23, 2007Hey 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 RelatedHow To Use DTS To Export To Access Using Global Variables ...

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:

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????

Passing Variables From Access Forms To Sp's
Mar 12, 2006Hi 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

Access To Variables In Custom Log Provider?
Jun 29, 2006Hello,
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!
How To Access Output Column Length Within Script Component?
Mar 7, 2007My 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!

Stand Alone Custom Dataflow Component Trying To Access MainPipe...
Feb 4, 2008Hi,
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.
How To Access Package Variables In A Custom Task
Jul 3, 2006Hi Everyone,
I created a script task that uploads a file to a HTTPs site. The script task works well and now I want to turn this script task into a custom component...
I'm having problems on how to call the variables I have in the package, I already locked them for reading, but how am I suppose to access them and how can I put their values into strings so I can easily call them in the WebClient.UploadFile method?
Also, I am very new to custom tasks in SSIS.. and would appreciate if anyone of you can send me something (code, link, etc.) of a very simple custom task without any form or properties, that I can try to study.
Basically, what I want my custom task to do is,
1. Read the varialbes in the package.
2. use the variables values as input in my WebClient.UploadFile("varURLstring", "PUT", "varFilePath")
as you can see, my custom task is really simple... but I'm a noob here and I don't know where to go.
Thanks in advance,

Problem Using SSIS Script Component To Access SRSS Service....
Feb 19, 2007I'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??
Custom Task: How To Access/modify The Variables Of A Package
Feb 1, 2007Hi,
I'm trying to simplify the deployment process of my project. I already had some troubles with the config files but lets say I solved that issue. I'm going to read a flat file and set the variables of my packages from this file. I was thinking to use a Script Task to do that but I will need to copy this task in every package (I have at least 30). So if I want to make some change this will be painful.
Then, I came up with the idea of creating a Custom Task called Config File Task. I'm working on this but I got stuck trying to get the variables from the package that is running my Config File Task.
This is the code I had in the Script Task:
Dim streamReader As New StreamReader(Dts.Variables("ConfigFilePath").Value.ToString)
Dim line As String
Dim lineArray As String()
Dim variableName As String
Dim variableValue As String
Dim readConfigurations As Boolean = False
While (streamReader.Peek() <> -1)
line = streamReader.ReadLine()
If line = "[CONFIGURATIONS]" Then
readConfigurations = True
ElseIf line = "[/CONFIGURATIONS]" Then
readConfigurations = False
Else
If readConfigurations And line <> "" Then
lineArray = line.Split("|".ToCharArray())
variableName = lineArray(0).Trim()
variableValue = lineArray(1).Trim()
If Dts.Variables.Contains(variableName) Then
Dts.Variables(variableName).Value = variableValue
End If
End If
End If
End While
Dts.TaskResult = Dts.Results.Success
All I want to do is set the variables that exists in each package from the config file. In my UI Class (ConfigFileTaskUI.cs) I can have access to the variables via the TaskHost which is passed as an argument of Initialize() method.
Any thoughts? I'd really appreciate some help!
P.S. I've been working on this for 2 days!
Use Of A SSIS Variable Of Type “Object� Inside Script Component And Task Component
Mar 16, 2007In 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, 2007Hi 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, 2006I 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.
Does anyone have any suggestions?

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[")

rd.Close()
Dim wr As StreamWriter = New StreamWriter(fileName)
wr.Write(xml)
wr.Close()
Dim xdoc As XmlDocument = New XmlDocument()
xdoc.Load(fileName)

Execute DTS 2000 Package Task Editor (Inner Variables Vs Outer Variables)
Sep 4, 2006 Hi,
I am not comfortable with DTS 2000 but I need to execute a encapsulated DTS 2000 package from a SSIS package. The real problem is when I need to pass SSIS variables to DTS 2000 package. The DTS 2000 package have 3 global variables that I can identify on " Execute DTS 2000 Package Task Editor - Inner Variables ". I believe the SSIS variables must be mapped on " Execute DTS 2000 Package Task Editor - OuterVariables ". How can I associate the SSIS variables(OuterVariables ) to "Inner Variables"? How can I do it? Much Thanks.
