HELP: How Do I Pass Variables From Control Flow To Data Flow
Mar 9, 2007I have an Execute SQL Task that returns a Full Rowset from a SQL Server table and assigns it to a variable objRecs. I connect that to a foreach container with an ADO enumerator using objRecs variable and Rows in first table mode. I defined variables and mapped them to the columns.
I tested this by placing a Script task inside the foreach container and displaying the variables in a messagebox.
Now, for each row, I want to write a record to an MS Access table and then update a column back in the original SQL Server table where I retreived data in the Execute SQL task (i have the primary key). If I drop a Data Flow Task inside my foreach container, how do I pass the variables as input to an OLE DB Destination on the Data Flow?
Also, how would I update the original source table where source.id = objRects.id?
Thank you for your assistance. I have spent the day trying to figure this out (and thought it would be simple), but I am just not getting SSIS. Sorry if this has been covered.
Thanks,
Steve
SSIS Variables Between Data Flow And Control Flow... How To????
May 17, 2007Hi everyone,
Primary platform is 64 bit cluster.
How to move information allocated in SSIS variables from Data Flow to Control Flow layers??
We've got a SSIS package which load a value into a variable inside a Data Flow. Going back to Control Flow how could we retrive that value again????
Thanks in advance and regards,
ForEach Loop And Data Flow
Jul 7, 2006In my Control Flow, I execute a data flow that opens a flat file and populates the file into a recordset.
Back to my Control Flow, I have a ForEach container that uses a ForEach ADO Enumerator. Inside the ForEach, I execute an "Execute SQL Task" that updates a table.
This is where I'm confused, while in the ForEach, I also want to call a Data Flow and use the current record (record in my ForEach) and perform several lookup tasks. Unfortunately, I'm now sure how to use the ForEach record as a source in my Data Flow....What am I missing?
Thanks,
Gary
Variables In Data Flow OLE DB
Feb 2, 2007I'm storing a sql command (could be an SP call or simple select) that I would like to pass into the "OLE DB Source" container in my data flow task. If I choose Data Access Mode: SQL Command from variable, I get an error saying there is a data source column with no name.
I've fought SSIS pretty good up to this point. I realize you need to "initialize" variables & expressions in the control flow ahead of time if you want to access them in the data flow. But I was kind of hoping that all I would need to do in this case would be pass a SQL command into a variable and access that somehow in the data flow without jumping through any hoops. Is this possible?
This is a great forum btw, thanks,
Phil
Data Flow Task Within For Each Loop Not Executing
Aug 22, 2007All:
I am sure I am missing something really silly but I am not able to figure out what. The For Each Loop uses an ADO Enumerator and passes variable values to a data flow. In executing the package the loop runs fine but nothing is happening to the data flow. When I move the data flow out of the loop it runs fine. What is going on?
Thanks!

Data Flow Inside For Each Loop - Error Handling
Jun 23, 2006Hopefully this is an easy question:
Inside of a for each loop (looping through an ADO record set of objects to import) I have a data flow task (along with many other processes).... if the dataflow task suceeds I log success in a table. If it errors I want it to fail the dataflow task (which will fire off my Event Handler for that data flow and log the failure, email etc) BUT I want it to continue the loop - I can't seem to figure out how to get the data flow object not to fail the whole loop. If any other objects inside the foreach, other than the data flow, fail I would like the whole loop to fail. Also if possible (but not a requirement) I would like it to have a threshold where if the data flow fails X variable times it will fail the package.
I am having difficulty how to not fail the loop when the import data fails..... just looking for a simple "on error next" type logic for that specific object in the foreach but not the rest. Thanks in advance for the help/advice.
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!
Foreach Loop, Data Flow Task Buffer Failed
Jun 5, 2006I have a package that runs fine by itself. But when I run it inside a Foreach Loop container on a parent package, I got a buffer error after a few loops. Here are a couple of the error lines:
A buffer failed while allocating 49085616 bytes.
The attempt to add a row to the Data Flow task buffer failed with error code 0x8007000E.
I already played around with the Data Flow task€™s DefaultBufferMaxRows and DefaultBufferSize properties, and I am still getting the error. Just wondering if there is a memory leak or something with the Foreach Loop task. I haven€™t install SP1. Maybe SP1 fixes this issue?
Integration Services :: Multiple Data Flow Tasks Within Foreach Loop Container
Nov 3, 2015Suppose if I have a “Foreach Loop Container” that iterates over a list. Is it possible to execute different data flow tasks based on the input?
Example : List contains elements L1, L2 & L3.
ForEach Loop Container checks the input. If its L1 then it should execute DF Task1, If L2 then execute
DF Task2 and similarly for L3.
Is it possible to achieve this?
How Can I Check Variables Comes From Data Flow In Predence Constraints And Conditional Transformation?
May 1, 2008
Hi,
I have Variable , data source and conditional transformation which checks the count(*) if the count == 0 then I connect an script component and change variable to false(initial it is True) and write into a log file...
Then I check that variable on predence constarint at workflow if variable==True then success. BUT
Whenever I run the package my dataflow gets green even the condition does not meet like count==0 . So
my variable's value is "False". Actually if the condition doesnt meet then my script shouldnt work.
Am I missing something???
Integration Services :: SSIS - Can Use Variables In A Data Flow Task Command

(I am assigning values to those variables from C# code)
The query should look like this:
select ordernumber, customerid from salesorder
where statecode=3 and datefulfilled between @variable1 and @variable2
Is There Away To Reference Global Variables In A Lookup Transformation That Are Set Outside A Data Task Flow?
Mar 31, 2008
The logic I am trying to recreate via SSIS is the following SQL statement:
insert into db3.dbo.targettable1 -- Target database table
(SiteC,
Objecte,
Attrib1)
select distinct ?,
?,
from ? -- Source database table
join dbo.targettable2 c1 -- Target database table
on c1.Alias = ? and
c1.CSetID = ? and
c1.FacID = (select f.PFacID
from dbo.Fac f
where f.FacID = ?)
where not exists (select * from dbo.targettable2 c -- Target database table
where c.Alias = ? and
c.FacID = ? and
c.CSetID = ?)
I have an OLE DB Source that consists of an expression to approximate the following portion of the Above Select statement:
Select ?,
from ? -- Source database table and
The package has 2 global variables User:CSetID and User::FacID whose scope is global to the package and whose values are set within a Foreach Loop Container outside of the Data Flow Task
I was trying to reference the 2 global variables within the Looup Transformation to recreate the following portion of the SQL statement.but encounter errors:
join dbo.targettable2 c1 -- Target database table
on c1.Alias = ? and
c1.CSetID = ? and
c1.FacID = (select f.PFacID
from dbo.Fac f
where f.FacID = ?)
In the Advanced Editor window of Lookup Transaction
select * from
(select * from [dbo].[targettable2 ]) as refTable
where [refTable].[Alias] = ? and [refTable].[FacID] = ? and
[refTable].[CSetID] = ?
Is there away to reference global variables in a Lookup Transformation that are set outside a Data Task Flow?

How To Pass Parameter Froon Control Flow To Data Flow
Feb 14, 2006Hi, All,
I need to pass a parameter from control flow to data flow. The data flow will use this parameter to get data from a Oracle source.
I have an Execute SQL task in control flow to assign value to the Parameter, next step is a data flow which will need take a parameter in the SQL statement to query the Oracle source,
The SQL Looks like this:
select * from ccst_acctsys_account
where to_char(LAST_MODIFIED_DATE, 'YYYYMMDD') >?
THe problem is the OLE DB source Edit doesn€™t have anything for mapping parameter.
Thanks in Advance

Logging The Foreach Loop Container's Variables
Apr 23, 2008Hello
I would like to loop through a folder and then log the folder's content, as in the names of the files, into a database like all the events get logged. Here is what i have done. I put some files into the folder c: emp made a loop through it, set up a variable 'temp' scope is the foreach loop, set the variable raisechangedevent to true. I have also confgigured the loop to put the result of the looping, in the temp variable in the variable mappings tab.
Strangely nothing is recorded into the "execution results" when i test run the package ? Do i need to make a event handler for the onvariablevaluechanged event for the foreach loop container to be able to get the value of the variable logged or is there something other that i'm missing ?

Is There A Way To Set A Variable In A Data Flow From A SQL Statement (like In Control Flow)
Jan 12, 2006I'm currently setting variables at the package level with an ExecuteSQL task. This works fine. However, I'm now starting to think about restartability midway through a package. It would be nice to have the variable(s) needed in a data flow set within the data flow so that I only have to restart that task.
Is there a way to do that using an SQL statement as the source of the value in a data flow?
OR, when using checkpoints will it save variable settings so that they are available when the package is restarted? This would make my issue a moot point.

Lookup Task Data Flow Transformation Causes Data Flow Task To Hang?
Dec 28, 2007Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)

The same package works fine against a similar test table with 150k rows.
http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.
Integration Services :: SSIS Foreach Loop Container Passing Variables To Store Procedure
Sep 8, 2015I am having a challenge to pass the filename variable from SSIS Foreach Loop Container to SQL store procedure. I have an "Execute SQL Task" inside "Foreach Loop Container" which will receive the input filename parameter passed by the Foreach Loop Container. The store procedure command line is defined as "EXEC sp_mySQLStoreProcedure ?" within the "Execute SQL Task". The Foreach loop container will gather the filenames from File System then put it in the filename variable one by one. I would like to pass the filename variable as the input parameter to the sp_mySQLStoreProcedure in the "Execute SQL Task". How can I connect the variable and the store procedure so that it will process all the input files gathered by the Foreach Loop Container?

Need To Save A Value From Data Flow A To Use In Data Flow B
Mar 20, 2007Good morning, all,
I am working on importing an Excel workbook, saved as multiple CSV flat files, that has both group level data and related detail row on the same sheet. I have been able to import the group data into a table. As part of the Data Flow task, I want to be able to save the key value for the group, which I will use when I insert the detail rows.
My Data Flow has the following components: The flat file with the data, which goes to a derived column transformation to strip out extraneous dashes, which leads to the OLEDB Destination component.
I want to save the value as a package level variable, so that I can reference it in another dataflow.
Is this possible, and if so, at what point do I save the value?
Thanks,

Data Flow Stuck In Phase The Final Commit Data Insertion Has Started
Jun 19, 2007Hello,
I have noticed that for one of my data-flows, the process is really long during the phase "the final commit data insertion has started".
To be accurate, the process is fast until it reaches this phase. It happens often when I load millions of lines.
The extraction is done from a database SQL Server 2005 to a database SQL Server 2005, on the same server (with the SQL Server native provider).
I used a SQL Server destination but I have tried with an OLE DB destination and it is the same situation.
Why the process could be so long during this phase?
There is a way to optimised my package to avoid that?
Any idea is welcome.
Thanks.

Data Flow Task Error To Extract Data From Sql Server To Excel
Mar 28, 2008Hi All,
I want to export data from SQL Server2005 to an Excel spreadsheet thru "Data Flow Task". I am using OLE DB for SQL Server for the source connection and a Connection To Excel as my destination source. The Excel spreadsheet (2003) exists and has the first row with column names. I don't have any warnings before trying to execute.
The SQL datable fileds are
i) ID - Int
ii) RefID
iii) txtRemarks - nvarchar(MAX)
iv) ddlWaterLevel - nvarchar(50)
While executing the tasks, I got the error
Error: 0xC0202025 at Data Flow Task, Excel Destination [427]: Cannot create an OLE DB accessor. Verify that the column metadata is valid.
Error: 0xC004701A at Data Flow Task, DTS.Pipeline: component "Excel Destination" (427) failed the pre-execute phase and returned error code 0xC0202025.
After analysing I found in the DataFlow --> Excel destination --> Advanced Editor for Excel Destination, the default data type for txtRemarks shows as "Unicode string [DT_WSTR]". But this is supposed to be "Unicode text stream [DT_NTEXT]". Even if I change the data type in the design time, It doesn't accept.
Please do help me out.
thanks
