I've set up a File System path inside a ForEachFile enumerator in SSIS 2012. I'm iterating over a directory, loading each file, archiving that file, then processing the next file, etc. I've set the Destination folder via an expression that uses a Project Param value, and I get the source file from the variable set in the ForEachFile enumerator. The File System task says it can't find my Destination folder:
Here's the File System Task:
And proof that the destination folder exists:
Why am I getting this error? I'd swear I've used the exact same technique in SSIS 2008 and 2005. This is 2012, but it should work the same way.
I met the same problem and to resolve it i create a variable and i put something like this in the path.Be carefull you must put double "\ \".
So the path must be like this:"\ \ \ \ad1hfdalhp001\ \d$\ \data\ \Archive\ \"
The DestinationConnection field must contain a reference to a flat file connection. The error is saying that you have no Flat file connection manager with that name.
DestinationConnection should not be a free text field. You should be able to open a drop down in the DestinationConnection field and select or create a connection manager.
You will need to configure your output file path as the ConnectionString property on the file connection manager referenced in the DestinationConnection field.
Using a UNC is still an option. Similar to as you've done with the Source, on your Destination, set IsDestinationPathVariable = True and then push \server\path into a Variable User::ArchivePath or similar.
Otherwise, it is as user3922917 indicates: if IsDestinationPathVariable is false, then you need to use a File Connection manager.
In your comments, you indicate that you're building the UNC path based on an Expression in the File System Task. I find I have a better experience when I build my expressions in SSIS Variables and then simply assign that Variable into the Task's Expression. While this step may seem to provide another layer of maintenance, put a break point on the Task and tell me what the expression evaluates to. And you can't. It's only available to the object to use and you are unable to inspect it so you're left high and dry if your formula is off. Which never happens when you're having to deal with escaping a UNC path

I have flat file source and connection manager. I need to configure its connection string as filename_* .txt. I have one variable on package level to read the directory path and then I am using it in expression property to read the file path as #FilePath + "filename__* " + ".txt". This is not working. I am not able to figure out how to configure file name as filename_*.txt.
In a case like this best practice is to use a foreach loop container of type File Enumerator, you can pass it a search string to scan for files and run a process using the found file name.
Note if you have multiple files in that folder it will run the same process for each file
The container will then execute everything inside it for each file found with that search string. You will need to map the found file name to a variable on the Variable Mapping section.
You can now use the variable as an expression in your file connection
Your control flow should look like this
I have set / array of hosts that fall in below three categories i.e
source_hosts (multiple servers)
ansible_host (single server)
destination_hosts. (multiple servers)
Based on our architecture the plan is to do the following Steps.
Verify if the files exists of source_hosts and has copy permissions for the source user. Also, verify if the "path to folder" n the destination exists and has permissions for the files to get copied. Checking if we are not "Running out of space" on the destination should also be considered.
If the above verification is successful the files should get copied from source_host to ansible_server
Note: I plan to use ansible's fetch module for this http://docs.ansible.com/ansible/fetch_module.html
From the ansible server the files should get copied over to the destination server's respective locations.
Note: I plan to use ansible's copy module for this
http://docs.ansible.com/ansible/copy_module.html
If the file already exists on the destination server a backup must be created with a identifier say "tkt432" along with the timestamp.
Note: Again, I am planning to use copy module for backups but i don't know how to append the identifier to the backed-up files. The module does not have any such feature of appending custom identifier to file names as of my limited knowledge.
I have the following concerns.
what would be the ideal ansible module to address Step 1 ?
How do I address the issue highlighted in Step 4 ?
Any other suggestions are welcomed.
Q: "What would be the ideal ansible module to address Step 1 ?"
A: Modules file and stat. Checking "Running out of space" see Using ansible to manage disk space.
Q: "How do I address the issue highlighted in Step 4 ? If the file already exists on the destination server a backup must be created with an identifier say "tkt432" along with the timestamp."
A: Quoting from the parameters of copy module
backup - Create a backup file including the timestamp ...
Neither the extension nor the place of the backup files is optional. See add optional backup_dir for the backup option #16305.
Q: "Any other suggestions are welcomed."
A: Take a look at module synchronize.
Q: "1. Is there any module to check file/folder permissions (rights) for copy-paste operation with that user id?"
A: There are no copy-paste operations in Ansible.
Q: "Requesting more inputs on how we can append identifiers like "tkt432" to backup filenames while using "copy" modules backup option or any other good solution."
A: There is no more input. Ansible does not do that.
Q: "I feel I won't be able to use the copy module and will have to fallback to writing shell scripts for the above-mentioned issues."
A: Yes. Modules shell and command could help with this.
I have a dataflow that is used to do transformation of multiple flat files from given folder using for each loop container. I have a flat file again as output file. The problem is that every time I execute the the job only the last file that got transformed will be stored in destination file.
Is there a way in SSIS I can create individual transformed output file instead on overwriting on same one over and over again?
For. eg. I have 5 flat files ,test_1.txt,test_2.txt,test_3.txt ,test4_.txt
and test_5.txt in a folder.
After the job ran I can only see the data from last file test_5.txt being
transformed in my destination file.
Here's steps on a working example I tested.
Variables
I have 3 variables defined:
FileName - To be used in the foreach loop
DestinationDir - where are the files going
SourceDir - where are the files I want to process
Foreach Loop Setup
I have a foreach loop configured as:
Expression for "Directory" set to #[User::SourceDir]
Retrieve file name set to "Name and extension"
Then under the "Variable Mappings":
That means as the foreach loop is iterating over the files in the directory it will be setting the "Name and extension" of the file its on to the variable #[User:FileName]
Data Flow Task
The I add a Data Flow Task inside the foreach loop:
Then inside the DFT I have a simple Flat File Source to Flat File Destination. We'll just pass the contents of each file to new files:
During initial development I'll manually pick one file to walk through setting each of the source and destinations. Then come back and change the connection managers and set an expression on the ConnectionString.
Connection Manager Expressions
SourceFile Connection Manager:
ConnectionString gets an expression as: #[User::SourceDir] + #[User::FileName]
DestinationFile Connection Manager:
ConnectionString gets an expression as: #[User::DestinationDir] + #[User::FileName]
Testing
I have 2 test files in my source directory and no files in my destination:
After I execute my package I get success and also get new files in my destination:
There are ways to do what you are asking in SSIS with variables and expressions but there is an easier way to accomplish it using command line.
Since you are just consolidating a text files into 1 you can use a command prompt to better handle your issue:
copy *.txt output.txt
I have about a dozen folders with up to 2500 PDF's. I need to move out 163 of the PDF's from t-SQL statement into a "not to be sent" folder in SSIS.. I already have the for each loop container and file system task.. How can I only search/select the files from my T-SQL statement to be moved?
Note: I already have the filenames that need to be moved in my T-SQL statement
In your foreach loop container, which I assume is enumerating through the files, put a script task in front of your file system task.
The script task will check the current file name against your T-SQL results, either by running the query, or checking it against a variable that contains the results.
Then it will set a boolean variable to either true or false if the file should be moved, and in the precedence constraint leading to the file system task, you check the value of the boolean variable.
I think you might be asking, how do i use the TSQL statement and results from it in SSIS.
Create a variable filenames type ADO.Object
Add an execute SQL task
Add you TSQL to it
Change Result Set to Full
Map Result Set to #filenames
Add for each
Enumerator is Foreach ADO Enum
Set filenames as object
Map a new variable type string called filename to index 0
Add your file Transfer Task and use filename.
*** This assumes that filename has the full path.
I'm working on creating a csv export from a SQL Server database and I've been familiar with a process for doing so that admittedly, I've never completely understood. The process involves creating a "template" file, which defines the columns and structure for the file export. Once the "template" file exists, you can use a Data Flow task to fill it and a File System Task to copy it to the final storage destination with whatever file name you'd like (frequently a date/time stamp).
Is there a reason that you can't simply create a file directly, without the intermediate "template" file? I've looked around for a bit and it seems like all the proposed solutions involve connecting to an existing file. I see that there is a "Create File" Usage type for a "File" connection manager, but you can't use it in any File System Task. The only File System Type connection managers you can use relative to a file are "Copy", "Delete", "Move", "Rename", and "Set Attributes".
Is there a way to create a file at package run time and fill it?
The whole point of SSIS is to create a data flow with metadata so that the data can be manipulated - if you just want to go database direct to CSV you are probably better off using bcp (bulk copy program) from the command line. If you want to include it as part of a SSIS package just add an Execute Process Task and add the command line to that. You can dynamically change the included columns or the output file by adding an expression to the task. You could also call bcp though TSQL using an Excute SQL Task.
One other option is to concatenate all your columns in your query inter-spaced with a comma literal and output to a text file with just one very wide column.
