I am new to SSIS. I want to check the error state. If failure, I want to move the file to the error folder. If success, I want to move the file to the success folder.
Example: If number of rows is less than the flat file is update in the DB it should prompt an error and drop the file in to folder and next file should continue updating in the DB.
You could create a For Each Loop that iterates once per file you want to process. By default, this loop's MaximumErrorCount will stop it from iterating after the first failure. Since you want it to still continue on through the other files, set MaximumErrorCount on the loop to 0 (0 = infinity).
Place your data flow inside the loop. Then, attach two File System Tasks to the data flow--one with a precedence constraint of success and the other of failure. If the data flow completes with a success status, the "success" File System Task will run, moving the file to wherever you'd like. If the data flow completes with a failure status, the other File System Task can copy the file to the appropriate failure location.

I have an SSIS package that looks in a folder, loops through each file inside, imports file to SQL Server, executes a SQL task, then needs to delete the file, then loop through next one. The import and looping works without the delete file step (File System Task), but the delete file errors with the message "Failed to lock variable. The variable cannot be found." The variable in question is the variable I created for "Current File". It's being used by the first part of the For Each Loop container to look up the current file and import it successfully. What I think is happening, importing the file locks the variable. Then when it's going to delete the file based on the variable, it can't access the variable because it is locked, so it fails. Any idea how to allow it to import the "Current File" based on the "Current File variable", then delete it based on that same variable, then loop through the rest of files? Taking the delete file control out of the For Each Loop is not an option, because I need to delete each file after it imports - if I do a delete after all import, I might delete files in the directory which got there after I ran the import, so I'd be deleting non-imported files, I think. Thanks for any help!
A workaround to this issue would be to create a new object variable. In your current loop you can populate it with the full path and file name of each file that is imported. Then create a second "For Each Loop Container" control task that is enumerated on that object variable. Then within this new For Each Loop Container you can delete only those files (which were imported earlier) defined in the object variable. This way you do not delete any of the other files in the folder that you do not wish to touch.
The following link may help provide some idea as to how to set up the object variable in a For Each Loop Container and then parse out one file name at a time for deletion. Get List of Files
Let me know if this helps or if you need additional details.
I'm trying to create a package that imports excel files into a database using SSIS.
As the operation has to perform this regularly and the file names follow a convention but are not the same, and equally the sheet/tab names are not always the same, the SSIS package is set up as follows:
Main Container
->
First For Each container (call it FE1)
Obtains filenames (assigns to a variable)
->
Second For Each Container (call it FE2)
Obtains worksheet name and starts the process to import.
What I have done is create a "failure" precedence constraint from FE2 to a file system task process in FE1.
The idea is that the file move is done if the import is unsuccessful for whatever reason.
(once it works I'd like to create a "success" process that moves the file to the archive folder)
The file task process works when there is only one "for each container" (i.e. not nested the way it is now) but it fails when all the processes are in the nested container citing "file in use". I'm assuming this is because the first for each container is locking the file, hence why I moved the file task process to the first for each container and used a precedent control.
Any help and advice much appreciated.
For the benefit of anyone else who may have the same problem:
for love nor money could I get the excel connector to release the files, even when the move file task was outside of the loop.
In the end I recorded the files that were moved into a table in the DB and then executed a second package that contained the move file task and would iterate through the table rows with the list of successfully imported (and failed import) files and moved them to their destination based on fail/success flag.
It was the only way I got to successfully make this happen.
When having to iterate through the worksheet of each excel file (i.e. two excel connections effectively) SSIS would not release the files so I forever received the file in use error and failure.
I have the following use case:
I am trying to move the files in one folder to another folder. If any file is corrupt then whole process should be rolled back and no files should be moved.
For achieving this I am making use of one data flow task and one file system task. Data flow task would check for the integrity of the file and file system task would then move the file. These two tasks are in foreach container.
The transaction property of foreach is set to required and for the two tasks inside it, i am keeping it as supported.
Issue: There are 6 files in one folder which are to be moved. The file # 4 is corrupt. I want the whole task to rollback when system detects the corrupt file. However, this is not happening and files uptil file no 3 get moved.
Screen shot attached.
I have package SSIS package and i work with SSIS 2008. I have start package which call other package i want to read files in daily folder on WEB_DAV folder and insert records in tables and update some table and move this file to backup folder, but if one file in daily folder has error or one of task in for-each loop failed all the package failed. i want if any error occurred it save the log in log table and move this file to error folder and continue with remind files in folder .I can logging this actions but i cant move error file and continue working with remind files thanks in advance .
Use the error event handler with the propagate variable set to false:

the easiest way it selecting the loop container and set the property ForceExecutionResult = Success.
I have a package that needs to check if a file exists in a folder and if the file does exist then take a branch that will import the file to SQL Server and execute some stored procedures to process it. If the file does not exist then just end the current run of the package without error. I have all parts working just fine except for the file detection and branching depending on the results. (In other words currently it just runs as if the file is there and does the rest). I know how to use a script task to detect for the file and return an error if not found - I need to know how to make the main package just end without error in that case or go on and do the import and the rest of the processing if the file was found.
You could use a Foreach Loop container in the Control flow tab. Loop through a folder for a given pattern (say *.csv). Set the flat file connection manager to use the filepath obtained from the For each loop container as the connection string.
In this setup, the data flow task within the For each loop container will execute only if a file is found. Otherwise, it will end the process silently without any errors.
Here are few other SO questions where I have provided some examples about looping files using Foreach Loop container.

Hope that gives you an idea.
