Suppose 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?
I use a ForEach Loop Container in a ssis Package. The package has to look up in the directory 'f:ackups' for backupfiles and copy them into another folder.In my development environment it works fine. But if I run it on the SQL-Server with the SQL-Server Agent, the package logs always that the folder ist empty.Unfortunately the message is always 'empty folder' even if I define 'f:labla' as folder that actually not exists!
As filespecification I tried both *.* and *.bak .My assumption is, that the SQL-Server agent has not enough rights for that folder. But on the other side the agent is able to create backup-files in this folder.The SQL-Server Agent works under netservice control.
In my SSIS package I am using Foreach loopcontainer to load multiple flat files.
Now my requirement is that I want to load only those file which contains %vendor%.In source folder I have many files but I am interested in to load only those file which contains the string %vendor% in file name.
I 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?
View 4 Replies View RelatedIn order to update an Oracle table target from a SQL Server table source I need to use a Foreach Loop Container, so I can loop on the rows of the SQL Server table source. This source table has two columns: the old identifier to update and the new identifier to apply. I must use the value of the old identifier to filter the Oracle rows to update, while the new identifier is the new value to assign to the filtered old identifier.
I already know how to use the Foreach Loop Container when it is necessary to loop on an unique column of a table/view (using an object variable, using a Foreach ADO enumerator, etc.), but I need to loop on two columns.
I have a requirement to load multiple flat files in target table .
I have created the package which used to load files into target table using For each loop container.
But now requirement has been changed now I have to take only those files from table where status="Success" and max JobId. By the query I am to get those records which need to load into table.
Below query I am using to get the files which need to load.
select [JobLogKey],[SrcNm],[DestNm]
FROM [ConfigRep].[dbo].[JobLog]
Where [JobId]=
(Select Max(cast([JobId] as Int)) Jobid
FROM [ConfigRep].[dbo].[JobLog]
Where [JobStat]='Success')
Output:-
JobLogKey SrcNm DestNm
268 H:Data PlatformSource FileClient2LocHGSSpecLocation.txt Location.txt
269 H:Data PlatformSource FileClient1LocHGSSpecLocation.txt Location.txt
I have to load using above 2 files which are under SrcNm. I have created one variable called FileToLoad as Object and mapping to result set of above query. I have create JobId,SrcNm and DestNm variable to catch the record at every loop. I have created 2 For each Loop container
Below screen shot of outer Foreach loop. Till here Its working fine. Inner for each loop container not executing any task under that. How to get it done.
I have a requirement to read an encrypted file as a data source. I am not allowed to save an unencrypted text file version on disc at any time for any length of time, therefore I created a custom source component that reads an encrypted csv file, decrypts it, and then passes each row of data to the pipeline and ultimately to an ole data destination. Basically it is just a text file reader with an added class that adds functionality that decrypts the file before the component sets columns or reads rows.
The custom component, “Encrypted File Source”, has a custom property “encryptionkey” with the encryption required flag set to true (code below) and is declared as eligible to be set in the expressions.
IDTSCustomProperty100 EncryptionKey = ComponentMetaData.CustomPropertyCollection.New();
EncryptionKey.Name =
"EncryptionKey";
EncryptionKey.Description =
"Secure String key value to decrypt the file";
EncryptionKey.Value =
string.Empty;
EncryptionKey.ExpressionType =
DTSCustomPropertyExpressionType.CPET_NOTIFY;
EncryptionKey.EncryptionRequired =
true;
I want to be able to set the password for the encrypted file in the SQL Agent job that executes the SSIS project. This means I have an environment with a variable, “DataPassword”, that is set to sensitive. It maps to a Project parameter in the SQL Agent job that is also set to sensitive. And I now I want to access that sensitive Project Password inside my data flow, specifically in the Encrypted File source task that I created and set my EncryptionKey to that Project Parameter.
The problem is that SSIS says.
"expression cannot be evaluated. ... The Expression will not be evaluated because it contains sensitive parameter value "$Project::DataFilePassord" . Verify that the expression is used properly and that it portects sensitive information"

I am using SQL Server 2012, on a windows 7 box with VS2010 premium.
Is it possible to do? I'm getting lock violations in I try to execute several tasks in parallel.

How do you sort files from the Foreach loop container?
I love this component, except I can't get it to sort by filename.
Nice to know how to sort by timestamps also.

Hello
I have a question
How is foreach loop container - foreach ADO enumerator performace in SSIS package compares to use of cursors in stored procedures
Is there any articles comparing them
I understand a lot of factors can affect the performance, however what is expected performance for the foreach ADO enumerator loop for large dataset. What is Microsoft recommendation for that - recommended - not recommended (using large datasets - over million records)
Thank you
Arminr Bell
in a my SSIS 2012 pkg I'm using a Foreach ADO Enumerator container that reads an object variable in order to get an id value.This identifier is passed as an input parameter to an Execute SQL task to update an Oracle table: if this task fails the id is written on a SQL Server table. After the Execute SQL task execution, with success or failure, the flow go to another task in the container.
When an error occurs for the update on Oracle table, each tasks inside the container are executed but the container fails and the loop ends.I'd like to complete the entire loop respect to the identifiers present in the object variable also if the update operation on Oracle table goes in error.
In 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
Is there a way in a foreach loop container to exit if the foreach loop container has been executing for a certain amount of time?
View 3 Replies View RelatedIn my SSIS Package I am using For each loop container to load the data from csv file to SQL Table.
my file will be like abc_120554.csv
I want to places one script task before the foreach loop container to check if the file exist in the folder which start with abc_.what to do for same.
My package is having .csv file as a source and I kept OLEDB destination to load it.
Stored the .csv file in a shared folder and the exact path is given in Enumerator configuration of the foreach loop container. When I execute my package, it is giving the warning as below:
It is saying that file is not there in the specified path and directory is empty. I am running the SSIS package from TFS. I am sure that I have read and write access for the shared folder for my userID. Is there any access there to pick up this file from path.
I have used for-each loop container for loading excel sheet contains multiple sheets with same structure. It is loading data into SQL table even there is no data in sheets.
View 3 Replies View RelatedI have to import a number of excel spreadsheets. I'm using the classic Foreach Loop inside another Foreach loop approach. The outside loop (Foreach File Enumerator) cycles through the Excel files, while the inside loop (Foreach ADO.NET Schema Rowset Enumerator - ExcelSchema - Tables) to cycle through the individual Excel sheets in each file.
Nothing special there; however, for some reason these excel files have some "phantom" tabs that should not be imported. I call them phanton because they show up as an importable tab in a SSSIS import wizard but actually are not listed in the excel file structure (no, they are not hidden tabs, I checked).
My idea is to use a constraint to NOT import those phanton tabs. The name convention should allow me to do that because the normal tabs have the name 'AAAAAAyyyymmdd$' and the phantom tabs show up as 'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase (the line below was captured from the Local Variable window and show one of the phantom tabs name).
+ User::WorksheetName {'AAAAAAyyyymmdd$'_xlnm#_FilterDatabase} String
I tried using Len (@[User::WorksheetName]) == 17, which corresponds to the length of the normal tabs name ('AAAAAAyyyymmdd$'). However, it does not work. For some reason the portion of the phantom tab name after the ending single quote (_xlnm#_FilterDatabase) appears to be ignored.
I tested with a number of different expressions, including reversing the variable, to no avail. It seems that internally just the standard name between quotes is what the constraint sees.
I 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 tasks 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 havent install SP1. Maybe SP1 fixes this issue?
I have a for each loop(ADO Enumerator) container which executes for each Advertiserid which is coming from database. In for each loop I have to create a new excel file with the advertiser name. So if the loop executes 7 times there should be seven excel spreadsheets with seven advertiser names.
How can i create an excel dynamically in the foreach loop container.
Can we drag and drop Existing SSIS package into for each loop container ?

Hi
Can anyone point me to an example of using a ForEach Loop Container to step through the rows in a recordset. I cannot seem to see how this is done from the help files.
Thanks
I have a few hundred data files that I need to process in groups from oldest to most recent. To that end, I have created staging folders for each date that appears in the file names (example: 20060213) and moved all of the data files to the appropriate folders.
I also have these folder names in a recordset that has been sorted in ascending order, so the oldest date should be the first record, the second-oldest date should be second and so on. My thinking is to use this recordset with a ForEach Loop Container to loop through each folder, but I am not sure if Integration Services will necessarily loop through the records in order.
Can someone tell me whether the records will be processed in order or suggest a better alternative to make sure the directories are processed in the correct order?
Hi
Currently the ForEach Loop container is set to loop over the entire collection of records in my table, but I only need to loop thru the records where the status = x. How is that possible? Can I use expressions to set the enumerator to do something like this. Basiclly the collection values are used for further processing, and I would like to avoid looping thru records which have been processed already, which means they already have a status set to y. Please let me know. Thanks.

Could someone send me any links or information on how to loop through an ADO.NET dataset in SSIS? I need step by step information please.

Hi,
My Foreach Loop container has 10 different task inside. I want to execute the first task only one time. I have a variable with increases for each repition. How can I put precedence contstraint on the first task so that it should execute only first time and other task has to execute all the time.
Thanks
With a ForEach container, configured to loop through files in a
directory, if I have a problem with a file.. can I direct the loop to
skip on to the next file?
I'm processing structured files, first record of each is some
header info, body records are in the middle, and then the last record
is a trailer containg a checksum
So, for each file in the directory, I split the records into three raw
files, one for header rec(s) , one for body recs and one for trailer
recs. (based on line numbers and using a conditional split to direct
the records)
Then I start by processing the header recs in a dataflow.. if all goes
well there I move on to the next dataflow to process the body recs from
the DataRecs raw file.. etc...
I would like to do some validation at each processing step.. if a
header rec fails validation say... then I'd like to just stop
processing that file and move onto the next file...
Now, I don't see my validation throwing an exception... so its more
that I'd decide (maybe using an Audit ) that the header doesn't pass
validation.. then I'd like to put a record in an error table (with info
about filename, source etc, not just content of the current data row)
But not sure what approach to take on this...
If there is an appropriate section in BOL please point me at it...
Thanks

Hi everyone,
I am having hard time with foreach loop container. The for each loop container in my package goes over all the rows in a ADO enumerator recordset variable and shows row values one by one in message box. The problem is that it just keeps printing the first row infinitely. Could anyone tell me what could be wrong?
Thanks in Advance,
Dear All!

Hello,
I want to set up a Foreach loop container to loop through several flat files. I have a connection manager set up for individual flat files. The metadata for the files is all the same. They are fixed width files, and contain sixty five columns.
I didn't see a place in the container properties to configure the metadata of the files. How can a Foreach Loop Container 'know' the metadata of the flat files that I want to loop through?
Thank you for your help!

Hi,
Another classic example of something silly I must be doing
I have a "Foreach Loop Container" which uses a "Foreach ADO Enumerator".
The object source is a recordset variable.
Inside the "Foreach Loop Container", a lot of things are happening - some Execute SQL Tasks, Send Mail Tasks, Script Tasks and also a couple of Sequence Containers.
Now, I am getting 2 records in the recordset, but, the "Foreach Loop Container" executes just once.
Any Ideas?
Thanks in advance.
Regards,

Hello
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 ?
