Adding Foreach Container Programmatically And Setting The Enumerator Properties
Jul 10, 2007
Hi
I have a package which contains a foreach container. Can anyone help me in setting the properties for the enumerators programmatically??? I am trying to set the properties for the enumerator "ForEach File Enumerator"
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)
I will attempt to explain my situation more clearly.
I need to get data from a data source using a DataFlow Task (which pushes the DataSet into a Variable) and process the data row by row in a ForNext (ADO Enumerated) Container. I don't want to map the columns into variables because the number of columns and the data types vary considerably and I want to make my package as "generic" as possible.
Is there a way, in Script, to read the current row of the ForEach Container from into an ADO DataRow so that thie names and values of each column can be accessed?
I know how to read the entire DataSet object from a Variable into an ADO DataSet and iterate through the rows in the normal way but this doesn't suit my purpose. It would be really useful if there was a way to do somehing similar with the current DataRow in the ForEach Container.
To explain what I am doing, the idea is to use the Column Names and Values for each row to construct an xml fragement, store it in a string Variable and (in the next step) use the Web Services Task to call a Web Method with the xml fragment (from the Variable) as one of the inputs.
A less attarctive alernative would be to use a Scipt outside a ForEach Container and loop through the rows of teh DataTable as descibed above and perhaps call the Web Service Task from teh Script. The proble is that I don't know how to do this either and it woudl be much "neater" anyway to use the ForEach Container.
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.
im using a Foreach ADO Enumerator in my SSIS Package, which iterate on a DataSet from a SQL Task.
I use the "Variable Mappings" on my Foreach Loop to retrieve the values into User-variables. But what i need is a way to combine a value from the DataSet with a User-variable and assign this new value to a new User-variable.
Ever since installing SQL Server 2005 SP1, when using the Foreach Loop container in SSIS the Foreach File Enumerator and Foreach Item Enumerator are missing from the Enumerator drop down box. Anyone else seen this issue? and know how to fix it?
I have no "Foreach File Enumerator" oprtion in the Enumerator Property of the Foreach Loop Component.
I have this enumerator in the c:Program FilesMicrosoft SQL Server90DTSForEachEnumerators folder.
Also I check it in the GAC - it does not here. I try to execute gacutil.exe -iF ForEachFileEnumerator.dll, but it is failed with "Failure adding assembly to the cache: The module was expected to contain an assembly manifest." Seems it is not managed enumerator.
Please help me.
Also information on how to regeister unmanaged enumerators are welcome!
Would like to do a file System task and a data flow for each row in a table.
I use a ForEach container with ADO enumerator set to a rowset variable. The rowset contains all rows from a single table. What I want to do is as in pseudo-code below:
for each row in ADO rowset
varDestination=CurrentRow.col_file_name.value
FileSystemTask.Destination=VarDestination
FilesystemTask.Copy(Source to Destination)(copy excel file from fixed folder to multiple variable folders)
DataFlowtask.Destination=varDestination(Write data to an excel destination Next My problem is that I dont know how to access the values of fileds from my current row in the rowset. Request help and pointers to samples. TIA Kar
I set up a basic ForEach enumerator loop and specified files of type *.sql.
In the directory, I had some files I needed to keep but didn't want the package to touch, so I changed the extension to *.sqlo. Much to my dismay, the ForEach loop picked up those files. (Though it did skip the *.xml and *.bat and a few other types...)
I have a simple ForEach SMO Enumerator that returns the names of all the databases in the server identified by the SMO connection manager. I would like to populate the ForEach collection with just a subset of the names, based on some simple pattern matching. In his helpful book Integration Services, Kirk Haselden indicates that this can be done directly in the Enumerate field by adding qualifiers. However, I'm at a loss in regards to syntax.
What I have is: SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names'] which returns the database names
What I want is to limit the names returned to those where Left(DBName,5) == "abcdb" (for example).
I have tried adding some test expressions to the Enumerate field, however, the URN is constructed based on the properties of a combination of the Connection Manager and Enumerate fields, and I'm just created invalid URNs.
Hi: I a SSIS beginner and am hoping this is an easy one. I am using a Foreach loop container with an in-memory ADO recordset as the enumerator. The recordset has 3 columns and one of them I wish to fixup data in by calling a web service task that returns an integer. I see how to call the web service and return the integer into a variable but am unsure how to approach putting that variable back into the in-memory ADO recordset? Should I even be trying to do it this way? thanks! Henry
Is there a way to register a new ForEach Enumerator within SSIS, for example ForEach Email in Exchange Inbox?
Or is the solution to create an SSIS variable and use the ForEach From Variable Enumerator? I take it the variable has to implement IEnumerable, or IEnumerable<T>.
My preference out of the two would be to register a new foreach enumerator which would take some implementation away from the developers and reduce time spent on the tasks at hand.
I have a SSIS package this set to run at a specific time each day. If there are no files for the ForEach tool to work upon...while it doesn't 'fail'...I would like to test for the condition that the enumerator was empty...so that I could send an email message reminding someone to followup and investigate.
What would be the best way to test for that condition?
I have a Foreeach loop container that is looking for all the files in a specified directory. For each file in the directory I need to open the file, extract the contents, and pass the contents as a variable for a stored procedure call.
I was able to loop thru the files in the directory and see each file and store the name to a variable.
I was able to use an XML task to open one file via a file connection that connects to a specified file and store the contents in a variable and then execute the SQL task using the variable.
What I am unable to figure out is how to put the two processes together and get the XML task to open the file by using the variable that contains the filename. If anyone could help I would really appreciate it.
I have a ForEach file enumerator that executes a data flow for every source file in a specified directory. If there are no files in the directory, the package executes with a result code of 0.
I need the package to fail if there aren't any files found in the specified load directory. Is there a simple way to do this with the SSIS component, or will I have to script the entire file enumeration process inside script tasks to handle this requirement?
Thanks in advance for any assistance with this question. Please post replies to this forum.
Sorry that I open a new thread again but I didn€™t found any good tutorials about foreach loop container. I would like to read every row from one table and do something. I red something about sql task€¦ Can someone give a little instruction, please?
I using data flow task to import from flat file to database but i need to use Foreach Loop Container to import multiple files in specific folder and all will be insert in the same table
Is there a way to set a variable as a substring of the enumerator in a Foreach File Enumerator type? The Variable Mappings tab in the Foreach Loop Editor does not allow you to enter an expression.
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.
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.
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.
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...
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?
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?
Dear All! I have a "Foreach Loop Container" to search files in a folder. And I only want to search .txt and .txt.gz file. I set property "FileSpec" as "*.txt,*.txt.gz" but my container dont run. Can you help me? Thanks
