Error While Trying To Assign A Value To A Read Write Variable In SSIS Package Script Component

Sep 26, 2006

Hi,

I am trying to develop a SSIS package which will read the records from the flat file and insert them into a destination table. I have some validations written in script component. I have declared two Read Write variables with package level scope. when i try to assign a value to the variable in the script component and run the package, the package throws me an error "The collection of variables locked for read and write access is not available outside of PostExecute".

What should be done to over come the problem please help me on this regard

Thanks

Attempted To Read Or Write Protected Memory Error In SSIS

Mar 17, 2006

I'm trying to import data from a Sybase ASE 12.0 database called "OurTestDatabase" into MS SQL Server 2005. I started SSIS Wizard and indicated "Sybase ASE OLEDB Provider" as a source and SQL Native Client as the target. I'm gettign the following error message:

-----------------------------------------------------------------------------------------------------------------

Cannot get supported data types from the database connection

"Provider=Sybase.ASEOLDEDBProvider;Password=;Persist Security Info=True;User ID=sa;Data Source=sybase;Initial Catalog=OurTestDatabase"

Additional information

|_ Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (System.Data)

-----------------------------------------------------------------------------------------------------------------

The same data source worked with DTS when we thought we'd convert to MS SQL Server 2000. Is this a bug in SSIS? What can be done? Using ".Net Framework Provider for ODBC" is not a good option because this doesn't allow me to choose any tables from the Sybase source.

Any help is greatly appreciated.

SSIS Package Designer Lookup Component GUI Error?

Jul 5, 2006

Has anybody seen this issue already?

If you try to "enable memory restriction" from the Lookup component GUI you need to input both 32 and 64 bit size of maximum memory. However when clicking "OK" on the editor you get a message like :

TITLE: Microsoft Visual Studio
------------------------------

Error at Update Execution Logs [Lookup folder path 1 [4429]]: Failed to set property "MaxMemoryUsage64" on "component "Lookup folder path 1" (4429)".

------------------------------
ADDITIONAL INFORMATION:

Exception from HRESULT: 0xC0204006 (Microsoft.SqlServer.DTSPipelineWrap)

------------------------------
BUTTONS:

OK
------------------------------

You can only set the properties directly for mthe Properties window (F4).

I think this is a post SP1 bug in Visual studio designer...

Assign A Value To A Package Variable From An SQL Statement

Mar 30, 2008

Hi

I want to use a variable in a number of SQL statements as paramenter. But I am not sure how to assign the value I want to the variable. The value I want is the maximum week number from one of my tables. I know how to put this value into a new table (which is one field and One row), but I cannot see how to pass this value to my variable. Using the table in my SQL is not straight forward unfortunately, at least not for me.

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 ��Object�? 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!

Write Value From Script Component To Variable (Datatype Object)

May 8, 2008

Hi,

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.

Many thanks for any help

That's an easy one. I've got a Send Mail task which might send a message in plain text along with a SSIS variable.

ERROR: A Variable May Only Be Added Once To Either The Read Lock List Or The Write Lock List.

May 22, 2006

Hi,
I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.

From the parent package-> Execute Process Task->
dtsexec /F etc... /<pkg variable> = "servername"

Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)

I "sometimes" get the following error:

OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.

Help would be appreciated!

I have seen other posts on this but, not able to relate the solution to my scenario.

HowTo: Read/write Package Level Variables In Custom Task

Oct 13, 2006

Hello all,

I have been struggling trying to read and/or write package level variables from within my custom task. I'd like to be able to get and set values from within the Execute method of my custom task. I have searched this forum and the books online and can't seem to find the answer. I thought maybe I could use an expression on my task (mapping the package variable to a custom task public property) but that doesn't seem to be working for me. I also would have thought I could use the VariableDispenser object from within my task but the collection is empty. I have 3 package level variables configured and can't seem to find a way to access them (with intentions of getting/setting). Could someone point me to a good doc or provide an example that may accomplish this? Thanks!

(I'm using package level variables as a means of passing simple information between tasks that are not using a DB, if there is a better way I'm open to suggestions.)

Is Ssis The Only Technology That Can Read/write Raw Data Type Files?

Sep 21, 2007

I'm contemplating a sql server archive strategy that rolls really old data off any sort of dbms and onto low cost media like dvds in a non relational archive format. I dont want to ever worry about these archives spanning different versions of sql when i go to retrieve a range of data that happens to span sql versions (eg one disc was sourced from 2005 another by 2008 but my report needs a union of both).

So I'm thinking about neutral/efficient formats for these archives and a live homegrown catalog that can determine exactly what disc(s) need to be mounted based on passed from and to date parameters...all so that the data that might span discs (and versions and maybe even schemas) can be merged and loaded into my sql version d'jour's "throw away" archive database for a one time report or other unplanned activity.

I remember raw data types being very convenient as an ETL format for our customers who have ssis, but wouldn't want our sqlexpress customers to be left without the archiving capability. Do the "things" that read and write raw data files really originate in some special T-SQL command that all sql editions can use, or is it strictly an ssis thing?

Accesing Package Variable In Conditional Component

Oct 6, 2006

Hello Experts,

I am trying to load data to a sql table from flat file..I have a script component which will validate the data. I am also firing the errros when data validation fails. Once I encounter an error I want the whole package to be aborted. What I have done is declared a variable called errorcount (Scope :Package) and I am incrmenting this variable everytime an error is raised and next I have a Conditional Split which will check if this variable count is greater than 0 if yes I will not update the table.This is the only way I think this will work.

error I am getting is :The collection of variables locked for read and write access is not available outside of PostExecute.

I understand they r in the same data flow thats the reason I get this error but how can I by pass it ?

MY dataflow-> Flat File Source-Script Comp-Condtional Split-(If errorCount==0)-SQL Table

How can I redo the dataflow so that this err is not raised.

I have tried to add an output column (blnContinue) and use that in conditional stmt but as this is stored at row level values which have blnContinue as true are getting processed, I dont want this I just want to stop the package execution even if a single validation fails

Pardon my long question

Appreciate your help in advance

Error - Attempted To Read Or Write Protected Memory

Aug 22, 2007

Hi,

I am back with one more problem..

I have created few reports using SSRS 2005. I am using Oracle database in Data Source to fetch my data. It is working fine and showing me report correctly. But after running the report 8 to 10 times, it starts giving me Memory error. To get rid of that, I need to recycle (stop-start) ReportingService from IIS.

I am exactly getting following error...

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

I am not getting the actual problem, why is it giving memory error only after running few times? Please let me know if anyone facing same problem or knowing the solution for the problem.

Thanks,

The Return Of Problem Assigning Value To Package Variable From Data Flow Script Component

Jul 10, 2006

I have a Data Flow Script Component(Destination Type) and in the properties I have a read/write variable called User::giRowCount

User::giRowCount is populated by a Row Count Component previously in the Data Flow.

After reading http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=97494&SiteID=1 it is very clear that you can actually only use variables in the PostExecute of a Data Flow Script Component or you will get an error
"Microsoft.SqlServer.Dts.Pipeline.ReadWriteVariablesNotAvailableException: The collection of variables locked for read and write access is not available outside of PostExecute."

What I need to do is actually create a file in the PreExecute and write the number of records = User::giRowCount as second line as part of the header, I also need to parse a read/write variable such as gsFilename to save me hardcoding the path

(Me.Variables.gsFilename.ToString),(Me.Variables.giRowCount.ToString)

-they must go in the PreExecute sub --workarounds please-here is the complete script component that creates a file with header, data and trailer --Is there any workaround

Thanks in advance Dave

SSIS Script Task Alters Package Variable, But Variable Does Not Change.

Oct 25, 2006

I'm working on an SSIS package that uses a vb.net script to grab some XML from a webservice (I'd explain why I'm not using a web service task here, but I'd just get angry), and I wish to then assign the XML string to a package variable which then gets sent along to a DataFlow Task that contains an XML Source that points at said variable. when I copy the XML string into the variable value in the script, if do a quickwatch on the variable (as in Dts.Variable("MyXML").value) it looks as though the new value has been copied to the variable, but when I step out of that task and look at the package explorer the variable is its original value.

I think the problem is that the dataflow XML source has a lock on the variable and so the script task isn't affecting it. Does anyone have any experience with this kind of problem, or know a workaround?

SSIS Custom Data Flow Component - Variable Type Converter

Jun 27, 2007

Hi all,

I am creating a customer data flow component for SSIS for use in a package. I've got some custom properties that I am exposing using the supplied advanced editor (no custom property editor here).

Some of my properties are enumerated types, and I have deciphered how to get those properties to show as dropdown lists of their respective enumerations. (For those of you who may be looking as hard as I did as to how to accomplish this, see the end of this post.)

I also have a few properties which request SSIS package variable names - such as an file name variable. However, I can't figure out how to tell the advanced editor that the property is looking for an SSIS variable, so that it can show a dropdown list of package variables, much like virtually any other Microsoft supplied Data Flow component can.

Is there a Type Converter I could specify for those custom properties? Is there another way to instruct SSIS that my custom property is expecting a variable? Or do I need to code a custom UI for editing my Data Flow Task?

To create a dropdown list of values for a custom property that represents an enum, do the following:

1. Create your enum definition, such as "public enum ThisIsMyEnum { one, two }"

2. Create a new class that inherits from TypeConverter, such as "public class MyEnumConverter : TypeConverter"

3. Override "CanConvertFrom", and return true if "sourceType == typeof(string)"

4. Override "CanConvertTo", and return true if "destinationType == typeof(string)"

5. Override "ConvertFrom", and return the enum value (such as "one" or "two" in my example) that corresponds to the string passed in the parameter "value"

6. Override "ConvertTo", and return a string that corresponds to the enum value passed in the parameter "value"

7. Override "GetStandardValuesSupported" and return true

8. Override "GetStandarValuesExclusive" and return true to indicate that ONLY the enum values should be accepted

9. Override "GetStandardValues", and return a new StandardValuesCollection constructed with Enum.GetValues() of your enum, such as "return new StandardValuesCollection(Enum.GetValues(typeof(ThisIsMyEnum)));"

10. Just above your "public enum" declaration, add a "TypeConverter" attribute to link your type converter to your enum, such as "[TypeConverter(typeof(MyEnumConverter))]"

11. In "ProvideComponentProperties", after you've created your custom property like this: "IDTSCustomProperty90 propEnum = ComponentMetaData.CustomPropertyCollection.New()", add another line to specify the TypeConverter property of the property to the full assembly name of your type converter, like so: "propEnum.TypeConverter = typeof(MyEnumConverter).AssemblyQualifiedName;"

Read SSIS Package Contents Into SQL DB

Feb 1, 2008

Hi,

We have an extensive set of SSIS packages that run daily to build our datawarehouse. We have run into a bit off a maintenance issue which I am hoping someone can help me with. The SSIS packages execute stored procedures. What I would like to know is, is there a quick way to determine what SSIS package is running a certain stored procedure?

My first approach was to load the packages into a table in a database using various xml functions. Basically, the table would contain the package name, and then the stored procedures that package executes. I have run into some difficulties with this though. Has anyone tried anything similar or perhaps know of a tool which could provide similar functionality?

Some help would be much appreciated.
