Xml Result Set To A Variable In Ssis And To Access It In Script Task
Apr 28, 2007
Hi!
I have an sproc that gives an xml result set. I want to save this to a file but by using ssis and script task. Now, I do exec usp_myProc in execute sql task and get the result as xml. (I can get it as result set too but niether has worked). Now I pass this variable to my script task User::XRset.
In the script task I create a file and then I want to write xml result of User::XRset to my file. I am at loss.
I cannot find the data type for parameter mapping from Execute SQL Task Editor to make this works.
1. Execute SQL Task 1 - select max(columnA) from tableA. ColumnA is varbinary(8); set result to variable which data type is Object.
2. Execute SQL Task 2 - update tableB set columnB = ? What data type should I use to map the parameter? I tried different data types, none working except GUI but it returned wrong result.
Does SSIS variable support varbinary data type? I know there's a bug issue with bigint data type and there's a work-around. Is it same situation with varbinary?
I set up a connection to mysql using ADO.NET's ODBC Data Provider. And I'm running a simple query to return one table's maximum ID(int32 unsigned). There is no problem to achieve that.
But when I bind the result to a variable and excute task. It gives out error message: "An error occurred while assigning a value to variable "MaxAuditLogID": "Result binding by name "MaxID" is not supported for this connection type. "
I tried to change the type of variable around but with no luck.
I have an Execute SQL Task that executes "select count(*) as Row_Count from xyztable" from an Oracle Server. I'm trying to assign the result to a variable. However when I try to execute I get an error: [Execute SQL Task] Error: An error occurred while assigning a value to variable "RowCount": "Unsupported data type on result set binding Row_Count.".
Which data type should I use for the variable, RowCount? I've tried Int16, Int32, Int64.
i need to know how many rows are in a certain table and store this value in a variable in order to process this variable later in the package. of course i can build a data flow task within a row count component but as far as i understand it's necessary to read all data from a data source in order to use the row count component. now the question is if it's possible to use a sql task in the control flow and put a select count(*) statement within the task and then write the result of this select statement into a variable. shouldn't that be much more faster than using a whole dataflow for this problem?
I have looked thru several similar threads with errors like this, but have not found a resolution. I have a SQL Task that runs this query:
Code Snippet select NetRevenue = cast(sum(Base_Price + AL + MI + PO) as dec(10,2)) from Lancelot.DataWhse.dbo.GrossMarginDetail where tran_date_key <= ? + ' 23:59:59' and label_group <> 'X' and not (ar_ship_key in ('S999991','S998101''S998102')) and Document <> 'Cust Bal Debit Memo'
There is a parameter mapping of "User::LastSaturday" of type date. I also have a result set with a result set name of "0" with a variable name of "User::GrossMargin," which is defined as a double in the package. The task has a resultset type of Single row, and at the moment the answer that is returned is 66228637.10.
If I change the package variable to a type of string it of course works, but then I cannot do comparisons against it. I have step by step manually copied this from an existing DTSX, so I am baffled why this isn't working, and I'm ready to throw myself under a truck!
I also tried to bring it in as a string, then convert it in a script task, but I cannot figure out how to reference the input and output variables. I can't seem to find any relevant docs on how to do that...
If anyone has any ideas, I and my sanity would greatly appreciate it.
I am building a simple package that looks at the results of a sql query, prior to running the next step.
Basically Outline and settings
SQL task
Result Set: Full result set
SQL Source: Direct Input
SQL Statement: Select Count (*) FROM X
Parameter Mapping
Variable Name: User::C
Direction: Return Value
Data Type: Numeric
Parameter Name: NewParameterName
Result Set = NewResultName: User::C
Precedence Constraint
Evaluation Operation: Expression and Constraint
Value: Success
Expression: @C > 0 ( I originally tried User::C and received an error message)
Execute SQL Server Agent Job
If step one results greater than 1, then execute the SQL agent job (SRS Report) Using this setup I receive an error message stating "
TITLE: Package Validation Error ------------------------------ Package Validation Error ------------------------------ ADDITIONAL INFORMATION: Error at Package: The expression "@C > 0" must evaluate to True or False. Change the expression to evaluate to a Boolean value. Error at Package: There was an error in the precedence constraint between "Execute SQL Task" and "Execute SQL Server Agent Job Task". (Microsoft.DataTransformationServices.VsIntegration)
Any thought or suggestions would be greatly appreciated.
I am building this as an expression, but it is not working. I am trying to return the row count into a variable to use later in an update statement. What am I doing wrong? I am using a single row result set. I have one variable defined in my result set. I am receiving an error stating: Execute SQL Task: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_SingleRow". Any help is appreciated!
SELECT count(*) FROM hsi.itemdata a JOIN hsi.keyitem105 b on a.itemnum = b.itemnum JOIN hsi.keyitem106 c on a.itemnum = c.itemnum JOIN hsi.keyitem108 d on a.itemnum = d.itemnum WHERE a.itemtypegroupnum = 102 AND a.itemtypenum = 108 AND b.keyvaluechar = " + (DT_WSTR,2)@[User::Branch] + " AND c.keyvaluechar = " + (DT_WSTR,2)@[User:epartment] + " AND d.keyvaluesmall = " + (DT_WSTR,7)@[User::InvoiceNumber] + ")
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?
I have a SQL Task that updates running totals on a record inserted using a Data Flow Task. The package runs without error, but the actual row does not calculate the running totals. I suspect that the inserted record is not committed until the package completes and the SQL Task is seeing the previous record as the current. Here is the code in the SQL Task:
DECLARE @DV INT; SET @DV = (SELECT MAX(DateValue) FROM tblTG); DECLARE @PV INT; SET @PV = @DV - 1;
I've not been successful in passing a SSIS global variable to a declared parameter, but is it possible to do this:
DECLARE @DV INT; SET @DV = ?; DECLARE @PV INT; SET @PV = @DV - 1;
I have almost 50 references to these parameters in the query so a substitution would be helpful.
I am using SQL Server 2005 Integration Services to create new values for my tables. One step I must do is execute a query and the script task that receive its constraint (it is set to completion) must do different things depending on the query result.
My question is: how can I know the result of the precedence constraint?
I am trying to create a SSIS package that will create a csv of a dataset for daily events in the database. However there will be days that there was no activity and thus an empty dataset. The package still runs fine but I want to stop the package if the dataset is empty.
FLOW:
DATA FLOW task: get daily data and put in CSV file
FTP TASK: upload the file to FTP server
MAIL/Copy file task: Move the file and then send a confirmation mail on task completion status.
Pretty simple and it all works great, I do have a few complexities in there. What I would like to add and I am at a loss is at the beginning, if the OLE DB Task resultset is empty then move to Mail Task otherwise process normally. I have tried conditional split, derived columns, the only thing I haven't tried in Script task and am not sure about that yet.
I need to use a variable as column in SQL statement in Execute SQL task of integration services. I am setting Parameter Setting to map variable use it in the query like; select ? , col1name from tablename. But its not working. Anybody having any idea; would be of great help.
I had the SP, I want to call in Script Task , had the Result set data value then I need pop up message box. So how can I call stored procedure result in message box in ssis script task using C#.
and I want to use SSIS -OLEDB connection.  ConnectionManager cm; System.Data.SqlClient.SqlConnection sqlConn; System.Data.SqlClient.SqlCommand sqlComm; cm = Dts.Connections["OLE_TEST_"]; sqlConn = (System.Data.SqlClient.SqlConnection)cm.AcquireConnection(Dts.Transaction); sqlComm = new System.Data.SqlClient.SqlCommand("Exec dbo.sOp_xx_XXXe_VXX 280", sqlConn); sqlComm.ExecuteNonQuery();
I am creating SSIS package which using Execute SQL Task to which I am supplying one .sql file code is
delete from Test where ID = @ID
I defined @ID variable to SSIS and also path where .sql file placed but i am not able to execute this package i am getting error like can not find C:@Path file......
As i got information that passing such variable to .sql you need ADO.net connection so I changed SQLSERVER Database connection string to ADO.net .... after that when i set hard core value for these variable i.e for @ID and @Path then it runs sccessfully but by setting parameter i am getting above error
I've been having an error with Script Tasks in SSIS, where the error is every time I use a For Each In Dts.Variables, it always seems to crash. I'm trying to log the variables before I proceed in any other tasks. I'm passing in one value as a ReadOnlyVariables.
Here is the snippet of code:
Dts.Log(String.Format("{0} variables:", Dts.Variables.Count), 0, Nothing) For Each v As Variable In Dts.Variables Dts.Log(String.Format("{0} = {1}", v.Name, v.Value), 0, Nothing) Next
It's very strange because the Dts.Variables.Count gives me the correct number of items that I have passed in, but after I step into the For Each, I get this for Dts.Variables.Item:
In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user. Microsoft.SqlServer.Dts.Runtime.Variable
And as soon as I step into the next line, it crashes with this error:
Value does not fall within the expected range. at Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables90.GetEnumerator() at Microsoft.SqlServer.Dts.Runtime.Variables.GetEnumerator() at ScriptTask_932938a13af547149ade0331cf39ecfe.ScriptMain.Main()
My colleagues have tried this snippet of code and it worked fine on their machine, only mine has this error :-(
I tried to do several searches online and they recommended me to: Get the latest SP (I have all the updates now for .net and SQL) Re-register some .dll's such as dts.dll/pipeline/etc Change/toggle the PreCompileBinary Alter the script a little and rebuild.
None of these suggestions have had any success on this error that I'm having. I was wondering if anyone had any insight or had any similar problems as me. Any help would be much appreciated!
In my ssis 2012 package, I have a 'object' type variable with some table like records. I want to do some SQL operations like insert/update on the records in another table based on this 'Object' type variable records. Basically I want to use a MERGE statement with another physical table with the records in the 'Object' type variable.how to map/use the Object type variable in Execute sql task.I am not good in script task. How to utilize this Object variable in a Execute sql task? Â
I am working on the SSIS FTP Task that transfer file from one FTP server to local location, rename the file name, and finally transfer the renamed file to another FTP server. So I defined 2 FTP tasks.
For the FTP file receive operation, I need the remote path to be updated by a script and pass to the user define variable. So I set TRUE to IsRemotePathVariable. In the RemoteVariable, I set User::FTPSourcePath where the variable is set in the script with "/DMFTP/filename1.jpg"
For the FTP file send operation, I set TRUE to IsRemotePathVariable. In the RemoteVariable, I set User::FTPDestPath where the variable is set in the script with "/DestFTP/"
After all the setting, the FTP Task box show me the error as "Variable "FTPSourcePath" doesn't start with "/". Another FTP box show me "Variable "FTPDestPath" doesn't start with "/"
I have an Execute SQL Task that saves the results in a variable such as, RecCounts.
I have a Send Mail Task with a message source of: [User::RecCounts]
However, when I run the package I get this error.
Error: Failed to lock variable "[User::RecCounts]" for read access with error 0xC0010001 "The variable cannot be found.
This occurs when an attempt is made to retrieve a variable from the Variables collection on a container during execution of the package, and the variable is not there. The variable name may have changed or the variable is not being created.".
I have a SSIS package that has a SQL task which gets a result set and stores it in an SSIS object variable. The package then iterates through that result set in a foreach Loop Container. In the loop container I have a script task and a Send Mail Task. The script task sets the contents of the email message (through an SSIS String variable). In the dataset I have an EmployeeCode column. I need to select a single EmployeeCode and grab all the records associated with that code to create a single EmailMessage for that Employee that includes all their records. I've got that done, however the way I'm implementing it I then have to update the SSIS Object variable that holds the result set to remove those records I've already processed. Doing this causes an error at the next ForEach loop iteration stating it can't find a source.
Result Set from SQL Query (16 columns, 674 rows, 145 distinct Employeecodes) Employee Code EmailAddress Other columns 1 email1 set1 1 email1 set2 2 email2 set3 2 emial2 set4 2 email2 set5 etc etc etc
The first iteration should be sent to email1 where the body includes set1 and set2, the second iteration sends to email2 where the body includes set3, set4, and set5 and so forth.
The SSIS ForEachLoop Container is looping through the entire Result Set and passing into the .NET Script task the EmployeeCode (readonly) and the entire Result Set (readwrite) and setting the value of EmailMessage. So I create the value of EmailMessage based on the EmployeeCode and then use the value of Email1 and EmailMessage in the SendMail Task. I was trying to delete the rows I processed so I don€™t process them the next time the ForEachLoop Executes (otherwise I'll get duplicate emails).
Or if there's a different way to do this, I'm open to that as well.
See below for the code I'm using (colEmployeeCode is a ReadOnlyVariable and rsRecipients and EmailMessage are ReadWriteVariables in the Script Task).
Public Sub Main() Dim Header As String Dim Body As String Dim Footer As String Header = "blah"
Footer = "blah"
Try Dim olead As New Data.OleDb.OleDbDataAdapter Dim dt As New Data.DataTable olead.Fill(dt, Dts.Variables("rsRecipients").Value)
For Each row As Data.DataRow In dt.Rows If UCase(Trim(row("EmployeeCode").ToString())) = UCase(Trim(Dts.Variables("colEmployeeCode").Value.ToString())) Then Body = Body + "Label: " + Trim(row("colum").ToString()) + System.Environment.NewLine row.Delete() End If Next Dts.Variables("rsRecipients").Value = dt Dts.Variables("EmailMessage").Value = Header + Body + Footer Dts.TaskResult = Dts.Results.Success Catch ex As Exception Dts.TaskResult = Dts.Results.Failure End Try End Sub
I need to send the result of a procedure to an update statement.Basically updating the column of one table with the result of aquery in a stored procedure. It only returns one value, if it didnt Icould see why it would not work, but it only returns a count.Lets say I have a sproc like so:create proc sp_countclients@datecreated datetimeasset nocount onselect count(clientid) as countfrom clientstablewhere datecreated > @datecreatedThen, I want to update another table with that value:Declare @dc datetimeset @dc = '2003-09-30'update anothertableset ClientCount = (exec sp_countclients @dc) -- this line errorswhere id_ = @@identityOR, I could try this, but still gives me error:declare @c intset @c = exec sp_countclients @dcWhat should I do?Thanks in advance!Greg
In my current project i have a requirement to assign value of an aggregate transform to a variable. But i need to accomplish it without using a script task.
I am having a hard time setting the executable path for an Execute Process Task in SSIS. I have a variable that is initialized at package statup which holds the path to an executable in Windows. When I set the property "Executable" Path in an expression, I get a warning that the path for the executable is not set. One workaround was to try and initialize the variable with a bogus path with the hopes that the "correct" value will be written on run-time. NO LUCK. I still get the error and I cannot run the package until I put a static path.
I sometimes come accross this error when I attempt to execute an isolated task in the control flow. What is funny is that I am still able to debug the package.
It eventually resolves after a while. What could it be?
Thanks
Philippe

I have found that populating a data table from an SSIS variable (recordset) within a script task works fine first time round but produces no results subsequently:
Code Snippet
Public Class ScriptMain
Public Sub Main()
Dim ad As New OleDb.OleDbDataAdapter
Dim dt1 As New DataTable ad.Fill(dt1, ReadVariable("myRecordset"))
'below returns count of 5500 System.Windows.Forms.MessageBox.Show("dt1 Count: " + dt1.Rows.Count.ToString)
Dim dt2 As New DataTable ad.Fill(dt2, ReadVariable("myRecordset"))
'below returns count of 0 System.Windows.Forms.MessageBox.Show("dt2 Count: " + dt2.Rows.Count.ToString)
Dts.TaskResult = Dts.Results.Success
End Sub
Code Snippet
Private Function ReadVariable(ByVal varName As String) As Object

Try result = vars(varName).Value Catch ex As Exception Throw ex Finally vars.Unlock() End Try
I am try to transfer some tables data from one database server into another database server. I create a package in SSIS, and I use a variable to pass each table name. In Data flow, I use a OLEDB Source, but I cannot set the Data access mode to Table name or view name variable. Ever time, I will get this following error info "===================================
Error at Data Flow Task [OLE DB Source [31]]: A destination table name has not been provided.
(Microsoft Visual Studio)
===================================
Exception from HRESULT: 0xC0202042 (Microsoft.SqlServer.DTSPipelineWrap)

Some one can tell me what is the reason, or give me some examples.
In the Control flow tab, I have an Execute SQL Task that outputs full Result set into a variable of an object type. Now how can I write the contents of the Full Result Set into a text file using Script Task. I also want to format the following way while I output into a file:
Column Name 1 : Column Value
Column Name 2: Column Value and so on
I tried writing the contents of the Object Variable into a file, but the file had an output of single word: System.__ComObject.
Code for Writing the Full Result Set into a Text File
Dim RSsqloutput as String = Dts.Variables("objVariable").Value.ToString
Dim strVal as String = "File completed on " & Now() & vbCrLf & "------------------------------------------------------" & vbCrLf
I have a stored procedure that is executed via a sql script task that returns a full result set. I map this result set to a variable or object type. Is there a way to use this variable as a data source in a subsequent data flow task?
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!Can anybody give me a hint how to put sa resut from EXEC into avariable.EXEC is called:EXEC(@TmpQuery) and it returns a single int value (SELECT COUNT(*)....)Thanks!Mario.
