Hi 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,
I 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
Why isn't there some documentation on how to do this. This should be really simple and it has taken me 2 weeks and I still haven't gotten an answer. Please Help Does anyone know the answner or some place where there is some documentation!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I get the following error when I try to substitute the strings in the databasedetails collection with variables:
Error: Object reference not set to an instance of an object. StackTrace: at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.CheckLocalandDestinationStatus(Database srcDatabase, DatabaseInfo dbDetail) at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.TransferDatabasesUsingSpAttachDetach()
I created the following variables:
strDestinationDB = AirCL2Exp_new3
strDestinationDBPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDATAAirCL2Exp_new3_Data.mdf
strDestinationLGPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDATAAirCL2Exp_new3_Data.ldf
strSourceDB = AirCL2Exp
strSourceDBPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDataDataNewAirCL2Exp_Data.mdf
strSourceLGPath = C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDataDataNewAirCL2Exp_Log.ldf
I then assigned those variable to DatabaseDetails Collection:
DatabaseName = @strSourceDB
DestinationDatabaseName = @strDestinationDB
Inaddtion I also assigned the following to the two DatabaseFiles Collection:
for 0:
DatabaseFileSize = 0
DestinationFilePath = @strDestinationDBPath
FileType = DatabaseFile
SourceFilePath = @strSourceDBPath
SourceSharePath = @strSourceDBPath
for 1:
DatabaseFileSize = 0
DestinationFilePath = @strDestinationLGPath
FileType = LogFile
SourceFilePath = @strSourceLGPath
SourceSharePath = @strSourceLGPath
Hi, 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
Dear All!
My package has a Data Flow Task. In Data Flow Task, I use a Script Component and a OLE BD Destination to transform data from txt file to database.
Within Data Flow Task, I want to call File System Task to move file to a folder or any Task of "Control Flow" Tab. So, Does SSIS support this task? Please show me if any
Thanks
I'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.
Hi all! I recently started working with SSIS and one of the things that is puzzling me the most is what's the best way to go:
A small control flow, with large data flow tasks
A control flow with more, but smaller, data flow tasksAny help will be greatly appreciated.
Thanks,
Ricardo
In my SSIS Data Flow Task, I have a query that retrieves data based on a couple of date parameters. Is there a way we can pass/use the Variables defined in the SSIS package in the query ?
(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
I recently upgraded to on 2012 SP1 CU5 and have found the SSDT gui for SSIS to be almost unusable. I can't drag or resize items. Any time i try they either automagically shrink to the tiniest possible size, shoot off to some extreme or just shake uncontrollably I didn't have these problems on previous versions (dont remember what It was).
Is there a fix for this?
I am having a hard time with what appears to be something simple. I want to import an excel spreadsheet into a table on a daily basis from a command line. I created a package from the Import Wizzard in the SQL Management Studio and saved it. Since I want a clean table each day, my process needs to be create a temp table, import from the Excel file into the temp table. If that is successful, delete the original table and rename the temp table the original name. The point of this process is to provide for a fail-safe if there is some unforseen problem downloading the data on a particular day.
When I run the package, the first thing it does is delete the original table. I know this because the process shows the time that it finished is before anything else has started or finished. The time shown for the completion of the data flow task is about 2 minutes after that time.
This is maddening!!! The one thing I do not want to happen I can not seem to prevent. I have my control flow set on success. Why does it do this?
Hello all,
Is there documentation somewhere about multiple execution paths in SSIS control flow? I didn't find documentation anywhere. I have a situation where I have two tasks that take considerable time, but could be executed in parallel (to speed up things) and I was wondering whether SSIS supports parallelism.
To illustrate the issues in simultaneous execution, I created a test SSIS package. In the package, I have five tasks, let's call them T1, T2, T3, T4 and T5. The taks are connected with "green arrows" like this:
T1->T2
T1->T3
T2->T4
T3->T4
T5 is not connected. The tasks can be e.g. Send Mail tasks, that's not relevant to this issue. I put a breakpoint in each task and execute the package.
When I execute package, T1 and T5 become active, i.e. the arrow that displays where the package execution currently is, is in two tasks simultaneously. Now F10 (step over) doesn't seem to work "Unable to step. Not implemented". If I press F5 nothing happens. After I press F5 for a second time tasks T1 and T5 and executed. Why don't they execute with the first pressing of F5? I would additionally like to know whether these two tasks are executed in parallel or sequentially, i.e. in the same thread or in two threads? Is there documentation of this?
The execution stops at T2&T3. Again, pressing F5 doesn't do anything, but the second time I press F5 T2 and T3 are executed.
Hi Guys,
This is a question to the SSIS development team. I would like to know what are the requirements to implement custom SSIS Control Flow task in C++ . There is a documentation describing the process when implementing a managed task, but no such documentation exists for implementing a task in C++.
Thank you,
Ivan
I want to get the start time of data load and end time after data load and store it in a table which has mapping_id , mapping_name,start_time,end_time.
i use ActiveXScript task to get the start time before data load and store the mapping_id in a global variable,then data flow transformation occurs.
i want to use a global variable to store the mapping id ,so that i can update the end time after data load with that variable.how to do this?
is there any other way, i can get the start and end time of data load (other than the logging information)?
I'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
how to pass the variables as the data source in data flow in for each loop( ADO enumerator)?

Is it possible to use existing data flow components (Merge Join, aggregation,...) in a custom data flow component?
Thanks,

I 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.
Hi,
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!
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???
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?
There is a table with a column that contains Xml documents. For each record from my Data Flow Source, I want to pass in the Xml document and the node to interrogate, and return the value contained in the node. Like the Crm component, this is probably one I will have to write from scratch in C#, but I would like to avoid having to create the custom component if it already exists in the public arena.
Does anyone know of any Xml Ssis Data Flow Components that are downloadable for free?
I was working all day making changes to my 3MB package. I was adding a large number of transforms that were copied-and-pasted from elsewhere in the same data flow task.
All was going well. I even took the time to have SSIS lay out the task again (1/2 hour). Suddenly I started receiving some strange errors:
After the layout, I noticed two stray components 'way off in the upper right corner. I found that one of them had a duplicate name to a component which had been added hours ago. Even after deleting it, I got "duplicate name" errors.
I copied three components in one selection, and when I tried to paste them, got the error "can't initialize component on paste". I tried them one at a time, but got the same error.
I got errors about COM failures due to marshalling to another thread
I then exited Visual Studio and started it again. To my great surprise, the data flow task I was working on was still there, but was completely empty.
Comparing what I'm left with to my last version in source control, I find that the entire pipeline element is missing from the DTS: ObjectData element!
I'm developing a real love/hate relationship with SSIS. It varies from one day to the next. Guess what kind of day this is!
I am new to SSIS can anyone tell me the diff between control flow and dataflow. if all the transformation are done using dataflow than why do we use control flow. Sorry if I am asking you very basic question.
Hi,
I am using SSIS in SQL Server 2005 and want to have a query like this in my data flow task
Select a.*
from abc as a
inner join (Select max(b.id) as ID from xyz as b inner join pqr as c on b.id = c.id and b.id > ?) as t1
on t1.id = a.id
SSIS fails to detect the parameter (?) for the inner query and gives message.
"
Parameters cannot be extracted from the SQL command. The provider might not help to parse parameter information from the command. In that case, use the "SQL command from variable" access mode, in which the entire SQL command is stored in a variable.", so assuming this is your problem, then you can workaround.
"
The idea is to parameterize the inner query ,,,
(so if the above query doesnt make sense ignore it )
Hi, there,
I am having some problems with the loading of tab delimited text file (source) to a SQL Server table (destination) using the SSIS data flow task. Package has been executed successfully with no error msg. The number of rows in the text file also matches the number of rows in the SQL table. But, when I check the content of the table, I noticed some of the columns contain NULL which supposed to have value. This happens not to all the rows but only to some rows. I did some testing by removing some rows from the beginning, middle and end of the text file and re-run the package but the result is quite inconsistent. Sometimes, the field got filled, but sometimes, it just contains NULL where it supposed to have value.
What will be the possible causes to this?
Thanks in advance.

Hi,
I am experiencing an error where the ssis data flow task would freeze and stop data export from a oledb source to a text file. It doesn't generate any errors the ssis package would just hang. This only happens when I run it in 64 bit mode. When I change the mode to 32 bit the ssis never freezes and runs fine. Has anyone experience this? Is there a fix so I can run my jobs in 64 bit mode?
Thanks,
Hi ,

Hi!
When I add a Data Flow Task to a package, save it and then close. When I open it again, I get 3 errors and the detail of the Data Flow Task is empty.
I had try to uninstall and install my SQL Server 2005, but the problem continues.
Can some one help me on this?

Hi,
I have a SSIS Package which I would like to modify using SSIS API. I need to put new component between some two existing data flow's components. During this process I need to disconnect two data flow's components using SSIS API. How can I do that?
Thanks,

I am loading a lot of Excel and CSV files to SQL Server. Some loading may fail for various reasons. I want a file either be load as a whole or nothing. Currently I keep a list of failed filename and remove it at the end (I add a column for source file name).
Any better way to make sure a file is loaded as a whole or nothing?
Thanks,
Hi,
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.

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.
I would like to be able to have a "while" statement execute until all af the rows in a temporary table have be processed.
I know I can do this with counters.
However, I was wondering if anyone knows of a SQL equivalent of
"WHILE NOT EOF" as in "do this until you hit the end of the table".
Thanks in advance for any input.
Is it possible to setup a Control Flow at the solution level rather than at the package level? I'd like to setup a Control Flow that truncates multiple tables in a staging database then runs multiple packages that reloads those tables. Each package has a Control Flow tab that seems to be specific to the package. Is it possible to set something up that governs the execution of multiple packages?
Thanks.
