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.
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 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
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
insert into scn_transaction (sourceSystemName) values(@sourceSystem);
SELECT @txOut = @@identity
Whose purpose is to perform an insert into a table and return me the identity value of the inserted record, which I'll then use throughout the rest of my package. The identity column in the inserted table is numeric(18,0).
I execute the stored proc with the following sql with an OLE DB connection manager:
exec sp_newTransaction ?, ?
The first parameter is a string variable from earlier in the package, and the second is the output parameter. I have the following parameter mappings to the execute sql task:
The proc is correctly called, and the row insesrted, however I get a type conversion error when SSIS attempts to map the return parameter to my package variable... I've tried all sorts of combonations, and can't seem to get it to execute.
At one point I wasn't returning a numeric, but rather an int from the stored proc, and all was well until I went to use the variable in a derived column later in the package, and the type was converted quite incorrectly (a 1 was 77799789080 or some such), indicating a type conversion error likely related to the encoding of the number.
I'd like to keep the datatypes as numeric and make ssis use those - any pointers are greatly appreciated as to what type my package variable should be to allow proper assignment of a sql server numeric type to it.
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 trouble with script component. From time to time, I cannot see available data types of the column I´m just editing, in the Script component editor. The cell in the section Data Type properties, where normally combobox with data types is, is completelly black. This happens both with "old" script components I'm only viewing and new script component I'm creating.
This problem occured for the first time immediately after I migrated from Windows XP to Vista Bussiness 64bit and then several times without any obvious similarity among terms under which this appeared.
I have SP2 for SQL Server and SP1 for VisualStudio 2005 Professional edition installed.
I have an SSIS package that produces an Excel output file say File1 The Excel output file is created from a previous script task by copying a standard excel template to File1 after the copy, File1 has the disclaimer, legend etc... and a header row at row 10. So data rows should only start at row 11.
I was googling and found that people who read Excel file using an Excel source component have been successful reading from a range by the use of the OPENROWSET property. It is said to set this property to Sheet1$A5-B999 to start reading from row 5.
I tried to set the OPENROWSET property to be Sheet1$A11-B999 but am getting an error "Check that object exists" (Sheet1 does exist) So I guess it is the range that has an improper syntax or something else is wrong.
Hello, Using SSIS I am loading the data from SQL Server 200 to Oracle 10g R2. What should I use the destination object? Is it 'DataReader Destinations' or 'OLE DB Destinations'. If 'DataReader Destinations', how to specify the destination table? Thank you, Smit
I'm writing a custom source component that reads data from a SharePoint list with dynamic mapping to output columns. It's my first custom component and it's based on several samples and tutorials from Internet
Output columns are not created by the component itself, they must be added by user at design time. The component makes dynamically an association between SharePoint fields and available output columns at run-time (based on an mapping table).
I made a very basic skeleton and I encounter a problem when I add a column to output: it has no datatype and when I try to set one I have an the error Property value is not valid, The component xxxxxx does not allow setting output column datatype properties.

Hiii I am working on a application where I will upload my excel sheet.Then the application will read the header and will create a table to store the excel sheet. When the excel sheet will be uploaded first it will read the header of the excel and will display it inside a gridview to choose which columns are to be created along with datatype.I am giving u a snapshot
Column Name Select Datatype
Group Code
Emp No
Mem code
Amount
So Here the user is selecting tha data type.So I am passing the data type to my functions.But while assigning the datatype I am getting error that can no convert from sting to Microsoft.SqlServer.Management.Smo.DataType.I am giving u the demo codeprivate void button1_Click(object sender, EventArgs e) {ServerConnection objsvrconn = new ServerConnection(); objsvrconn.LoginSecure = false;objsvrconn.ServerInstance = "DEMO"; objsvrconn.Login = "sa";objsvrconn.Password = "sa"; Server objsvr;objsvr = new Server(objsvrconn); //objsvr.ConnectionContext.Connect();Table tb = objsvr.Databases["Demo"].Tables["Temp"]; Column c = new Column(tb, "GrpCode"); DataType dt = new DataType();dt.SqlDataType =(DataType)"Varchar" ---I am getting the error here.It only accecept from a enum i.e Datatype.Typename but doesnot accept like this dt.MaximumLength = 10; c.DataType = dt; tb.Columns.Add(c); tb.Alter(); }

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
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.
We've all seen this, where it uses an individual .write statement for each column.
Code Snippet
Public Overrides Sub AWCCogent_ProcessInputRow(ByVal Row As AWCCogentBuffer)
With textWriter
Dim item As Object
If Not Row.AddressID_IsNull Then .Write(Row.AddressID) End If .Write(columnDelimiter) If Not Row.City_IsNull Then .Write(Row.City) End If
.WriteLine()
End With
End Sub
But hard coding this seems not the smartest way. Especially since in my text file, there needs to be close to 100 columns. This could be a nightmare to update down the road. But I can't seem to find the object collection to loop through, like row.items which would seem to be logical.
The DATEDIFF(s, time1, time2) function output is of the 'datetime' datatype. How can I alter the 'datetime' to 'int' (or 'bigint') datatype to make it compatible with other variables in my calculations?
I have image type col.I'm trying to do the following,DECLARE @Data varbinary(16)SET @Data = (select imageCol from Table1 where id=3)As image datatype returns varbinary value, so I want to store image col value to a varbinary variable(or any other type variable, eg., varchar). But getting following error,========================================Server: Msg 279, Level 16, State 3, Line 2The text, ntext, and image data types are invalid in this subquery or aggregate expression.========================================Is there anyway to store image datatype value to a variable?Cheers.
I've created a stored procedure that converts an input string in richtext format (input as type TEXT) to plain text. I would like to be able to return this newly converted string, but I need to have some way of storing it in a local variable. My problem is that since I can't use the TEXT datatype as a local variable, I have no way of storing the large amounts of text I converted within the procedure. The VARCHAR(8000) just isn't large enough for my purposes. Anyone have any suggestions on how to go about doing this?
hi everyone, How do i declare a global variable in my package which takes a numeric value like User::VAR1 = 200402 and later on work on it
Later in the properties of the Dataflow i want to have this expression..
"select * from " + "TAB1" + " where Date=" + @[User::VAR1]
Here i want to subtract 190000 from @[User::VAR1] to get it in to myformat i.e the DATE format in the table
I can only see String datatype and othe datatypes wont allow me to to do any kind of manipulation in the expression: and to be more specific what are Int16 Int32 Int64 Double
I tried to use all of the above but the expression doesnt allow me as it says:
TITLE: Microsoft Visual Studio ------------------------------
Nonfatal errors occurred while saving the package: Error at Extract: The data types "DT_WSTR" and "DT_I8" are incompatible for binary operator "+". The operand types could not be implicitly cast into compatible types for the operation. To perform this operation, one or both operands need to be explicitly cast with a cast operator.

I have developed a simple package utilizing script component and variable. What I am trying to do is declare a variable in the parent package that can be change at run time to either 1 or 0. If 1 I want the package to succeed and branch off to run some child packages and if 0, then branch the other way and run another child package. In ether way, I want to be able to load one of the two child packages and not both.
I I declare a variable in my parent package like IsExist, int32 with default 0.
Then I have this code thanks partly to Jamie Thomson in " SSIS: Writing to a variable from a script task"
I also place the variable name in the ReadWriteVariables in the script component.
The problem now is it is always failing. It stopped at the script task and fail. This is not what I want. I want the package to execute another task upon failure. Anyone knows what I am doing wrong?
I am writing a custom transformation component that utilises a user variable.
Before using the variable at run time I am checking that the variable exists, but it would be nice to be able to add it if it does not. I cannot find any documentation on the subject, though I can see that the Variables class is derived from a ReadOnlyCollectionBase.
Is there a way to add a user variable with package scope from a custom component, either at run time or design time?
Why can varchar datatype variable only 4000 byte? For example: in a storedprocedure declare @aa varchar(8000) ...... while select @aa=@aa+@otherinfo end when the length is more than 4000 ,the data in the behind will be lost
I have a Store Procedure that kept wanting to specify something like maidenName = null if there is not value for maidenName field. The maidenName is already set up to allow null value. How do I write the store procedure to automaticaly recognized that if a field has nothing in it's a null? Below is the error I kept getting if I do not have the expiration number. Msg 201, Level 16, State 4, Procedure spInsertName, Line 0 Procedure 'spInsertName' expects parameter '@expNo', which was not supplied.
Each user who inserts a new SQL record from the FormView control needs to have their UserID in one of the fields of the record. I have the user ID stored in the Session("UserID") variable. I am having trouble finding the right way to get this done. I have tried using a hidden text box but I can't seem to assign the value. I have tried the Insert Parameters but that will not accept <%# Session("UserID") %> as a DefaultValue. Any ideas would be helpful. Thanks.
