How To Catch An Error Raised In The Forach Loop Container And Perform Cleanup Jobs Accordingly?
Nov 29, 2007
Hello everyone,
I have a package that should accomplish the following task:
- Loop on all files in a given directory.
- Before proccessing the current file in the Enumerator, it should be moved to a folder called "importing"
- Load the content of the file into a destination DB.
- After a successfull load, the file is moved from the "importing" to the "success" folder.
- If anything went wrong during the load process, the file should be moved from the "importing" to the "error" folder and an e-mail should be sent out to a certain admin account.
What I have done so far:
My control flow looks like this:
Foreach Loop containing the following tasks:
- File System Task: moving the current file from its original path to the "importing" folder
- Data Flow Task1: performing some transformations and insertions into the DB and raw files.
- Data Flow Task2: performing some transformations and insertions into the DB and raw files.
- Data Flow Task3: performing some transformations and final insertions into the DB.
- File System Task: moving the current file from the "importing" to the "success" folder
Question:
I do not know how to catch the event that one of my three Data Flow Tasks has failed and in this case perform two simple tasks, namely...
- File System Task: moving the current file from the "importing" to the "error" folder
- Send Mail Task: sending a configured e-mail message to a ceratin administrator.
I am new to T-SQL programming. I need to write a main procedures to execute multiple transactions. How could I structure the program so that each transaction will not abort if failed. Instead, the next transaction will keep running. At the very end the procedure will output the error and report them back to the main program in the output parameters. Looking for pseudo code.
Hi, I have a "Data Flow Task" inside" For Each container". Data flow task is processing file and updating the DB. If one of the file is correpted i want to move to error folder and continue with the next file. i have given red arrow to a script Task which move the file to error folder. but its not continuing with next file. how can Ido that? Any help
I everyone, I'm learning SSIS from a book but the most simple example is not working. The "For each task" I assigned "xyz" as name. I added a variable onto the "variables" window and called it "counter" Its scope was set to "xyz". Inside the "for loop" ("xyz") editor i assigned values as follows: "initexpression"-"@counter=0" "eval expression"-"@counter<5" "assign expression"-"@counter=@counter+1"
I added "Script task" onto the "For each" container and into the "Script task editor" I assigned the following values: "ReadOnlyVariables"-"counter" Its design script is set to:
Imports System Imports System.Data Imports System.Math Imports Microsoft.SqlServer.Dts.Runtime
Public Class ScriptMain Public Sub Main() Dim variables As Variables If Dts.Variables.Contains("Counter") = True Then Dts.VariableDispenser.LockOneForRead("Counter", variables) End If
MsgBox("You are in iteration: " & CStr(variables("Counter").Value)) Dts.TaskResult = Dts.Results.Success
End Sub End Class
Runnig it i get the following error message:quote: "DTS Script task has encountered an exeption in user code: Project name:ScriptTask_e7d98dbad0de4041bcdc9079a5c2fa65 Object reference not set to an instance of an object.." The line where the error occurs is from within the above script: "MsgBox("You are in iteration:" " & CStr(variables("Counter").value)) Anyone understands what that means? What is "object reference" and how do i set it to an instance of an object? Thanks

If i place a loop container inside a sequence container the connectors within the loop container disappear.... is this a bug - will the loop tasks still run in the correct order?? or will they fire off willy nilly??
I got some issues in my production environment, so please help me out. The following is the message I got from the replication monitor and I don't what to at this point.

Getting Access Denied To FileName Error When Using the Execute Sql Task (With File Connection) into a Foreach Loop Container.
Please Note :
I have a folder containing .sql files. I have to dynamically loop through the files and send them as a File connection Folder to the Execute Sql Task.
When I run this Package I am getting the follwoing error :
[Execute SQL Task] Error: An error occurred with the following error message: "Access to the path 'C:ProjectsFuzzy Lookup DataFlow ExampleScripts' is denied.".
Also I have logged in to the machine as Administrator and to Sql Server with sa.
Running MSSQL 2000 on Windows2000 in an NT domain. We have several jobs created by the web assistant wizard. They run along just fine for days or weeks, then all of a sudden SOME of them (?!) begin to fail with the message "Unable to perform a SETUSER to the requested username 'dbo' because the username is invalid for database 'xxx'" where xxx is of course the db where the proc resides. SQLAgent service is running as a domain admin and has not changed; job is owned by sa and has not changed; the domain admin in question is in sa role and has not changed. Something sure has changed, but what? Sometimes when this happens we can clear it up by deleting the web job and simply re-creating it. Today we have three culprits and none of our usual tricks are working. Why does this happen? How can we fix it? How can we PREVENT it! Thanks for any words of wisdom out there.
I encountered a werid bug that I can't figure it out in my stored procedure.Here's some sample code the can represent the scenario
Create Proc sp_test @DeptID Int as Begin Declare @i int=0 Declare @Count int=(Select count(*) from Total) while(@i<@Count)
[code]....
In the above code Total is a table that has employee name and its department ID and row_number info.The above code should list all employee info that belongs to one DEpt.but after I placed a try catch block the select statement returns no records.If I removed the try catch block it behaves correct.For example If three records reside in the Total table for a certain DeptID.
I expect the outPut will be Name age salary Mike 35 $60006 Tom 50 $75000 Frank 55 $120000
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
What I'm trying to do is take multiple "snapshots" of a membership for many months. I was trying to do this in a For Loop Container in which I added one to the month variable and subtracted one from an iteration variable each loop, unless the month variable = 13...then I would add one to the year variable, set the month variable to 1 and subtract one from the iteration variable. This, I was hoping, would allow me to initialize 24 to the iteration variable, 1 to the month variable and 2004 to the year variable, kick off the package, and get 2 years worth of "snapshots" in seperate files (one for each month). Here is the AssignExpression I thought would work:
The package states that the single "=" should be double, but I don't think that that is what I want to do (I tried doing this just to check, and it didn't like this either). I think that it is having problems with doing multiple things on both sides of the ":". What am I doing wrong?
We have a config table which has columns like pollingfolder, cop to folder etc. Data looks like this Config id polling folder 1 d:dataloadacn 2 d:dataloadship under ACN and Ship folders we can have more than 1 source files which had to be loaded into target the load process has to be repeated for each file in all the folders like ACN and ship I have used for each loop container to poll the folder. Can we set the directory to be polled at runtime taking from config table. For doing this I have used the property Directory in expression editor of for each loop. But it is not working. If I hard code the variable value in variables section , then its working. How to change the directory to be polled value at runtime?
I am using For each loop container in my SSIS package which will loop through more than one input file in the input folder. All the input files in the input folder are picked by one by one. All the input files in the input folder are executed with the same ExecutionInstanceGUID.
Now, my requirement is to get a new ExecutionInstanceGUID during the execution of each input file in the For each loop container. My package only contains the For each loop container with some logic inside that.
Please let me know if any one can help me for the same.
A very strange thing happened to me. I have a package that includes two For each loop containers. Each container has script tasks, sequence containers, etc. Both are Foreach ADO Enumerator basis. It works without any problems until I changed the position of one of them in the Control flow and added some code in the script task. After these changes I executed the package and both of For each loop containers did not execute the tasks inside of them, any task. However the execution color on the containers was green (success). How can it be?
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.
I am trying to move files from one directory to anonther using the For Each Loop Container and a File System Task. However, on the FIRST iteration of the ForEach Loop the variable that I am setting to the 0 index of the For Each Loop is returning me a valid directory with no file ( path only ) from who knows where ????
On the second iteration of the For Each Loop everything works as expected and I get the full path and file name and it iterates through all the files in the directory o.k.
So I have had to put a Hack to skip the fist iteration of the loop and then execute the File Task on the second iteration but I dont see anyone else doing this.
Where in the heck is it getting this odd directory from on the fist iteration ( its not my User varible because I am initializing it to \nowhereofile ). What am I doing wrong?
I've created a Send Mail task which works properly and now I'd like to send that email n times.
How do I such thing. I moved that task inside Foreach loop container and then I choosen "Foreach From Variable Enumerator" and then I've created a Int32 variable.
And now, I don't know how to tell that increments that variable
Hi. I am running a package using 'execute package' inside a for each loop file iteration. I have to iterate through some 10,000s of files to ETL source data, a resonably complex package. I want to set going and get some sleep but every 200 files or so I get a memory exhausted error and the task fails. Is there a short easy fix to refresh memory each iteration. If so please let me know. Just ignoring the failure at task level won't refresh the memory, will it?
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.
Simply trying to move a group of files from one folder to another folder and renaming the files with the monthyear in the middle of the filename..
I'm using a FOR Loop container and works find. The added complexity is I'm trying to rename the files the same tine and putting the Month Year into the file name.
I guess the struggle is how to get the file name out so I can manipulate it.
I tried creating variable(V_SOURCE) which stores the file path and create another variable(V_FILENAME) to hold the filename. I believe on the expression page of the FOR LOOP editor if I select the the file name and extension radio button, it should put the file name in the V_FILENAME variable.
In my file task trying to join the two variables together in another variable, keep saying my path is wrong with the file task kicks off.
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?
Hi I am using a foreach loop container and Data flow task dropped on it. According to the logic the dataflow task should be executed twice and for eacl loop fetches 2 records in the variable used in the sql in Data flow task. It works fine except that it does not iterate twice.It simply executes once. Please help
Hi, I am using a For Loop container with a script inside it in My SSIS package. Inside the script I am type casting one of the object variables in a class object of XMLReader Type. I am using CType Function for it. The For Loop is resulting in a memory leak and the references are not getting deleted even if they go out of scope. Does anyone have faced similar issue? Please guide.
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
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?
