Observe the following snippet of an SSIS package:
Both of the Flat File Destination tasks on the right are configured to write to the same Flat File Connection Manager, because I want all the failing records to be redirected to the same file regardless of which task caused them to fail.
SSIS is complaining on the second Flat File Destination, saying that the output file is in use by another process.
Is my stated goal simply impossible, or is there a way to redirect all failing records to the same output file?
No, you cannot do it this way. You need to use an Union All to combine the output before writing the output from different sources/transformations to the same destination.
If you have a process flow as described in the question, the package will fail on the second destination component.
The error message would be `The process cannot access the file because it is being used by another process.
To fix the issue, add a Union All transformation that will take the error output from Derived Column transformation and combines it with the error output from OLE DB Destination and the output of Union All transformation is then passed on to the Flat File destination.
Hope that helps.

Goal of project
-create "*\temp\email" directory
-start program to extract all emails that include xls attachments to the previously created folder
-use for each loop to cycle through each file in the folder, process, and shift to sql table.
The problem I am running into is caused by either a blank excel document (which is occasionally sent from a remote location) or some of the original xls reports only contain 5 columns instead of 6 that I have mapped now. Is there any way to separate files that include the correct columns from those that do not match?
** as Long as these two problems do not exist I can run the ssis package and everything runs without issue.
Control flow;
File System Task (creates directory --->Execute Process Task (xls extraction)-->ForEach Loop(Data flow Task "email2Sql")
Data Flow;
Excel Source (uses expression ExcelFilePath,#user:filepath) delay validation ==true
(columns are initially set to f1-f6 and are mapped to for ex. a,b,c,d,e,f. The Older files that get mixed in only include a,b,c,d,e.) This is where I want to be able to separate the xls files
Conditional Transformation split (column names are not in row 1, this helps remove "null" values)
Ole Db destination (sql table)
Sorry for the amount of reading, but for the first post I tried to include anything that I thought may be relevant.
There are some tools out there which would allow you to open the excel doc and read it. However, I think the simplest thing to do would be to use SSIS out of the box:
1 - add a file system task after the data flow which reads the file.
2 - Make the precedence constraint from the data flow to the file system task "failure." This will cause that to only fire when the data flow task fails.
3 - set the file task to move the "bad" files to another folder
This will allow you to loop through all the files and move the failed ones. Ultimately, the package will end in failure. If you don't want that behavior you can change the ForceExecutionResult property to be success. However, it might be good to know that there were problems with some files so that they can be addressed.

I'm writing a (what I thought to be a) simple SSIS package to import data from a CSV file into a SQL table.
On the Control Flow task I have a Data Flow Task. In that Data Flow Task I have
a Flat File Source "step",
followed by a Data Conversion "step",
followed by a OLE DB destination "step".
What I want to do is to move the source CSV file to a "Completed" folder or to a "Failed" folder based on the results of the Data Flow Task.
I see that I can't add a File System step inside the Data Flow Task, but I have to do it in the Control Flow tab.
My question is how do I do a simple thing like assign a value to a variable (I saw how to create variable and assign them a value at the bottom pane of Data Tools (2012)) depending of if the "step" succeeds or fails?
Thanks!
(You can tell by my question that I'm an SSIS rookie - and don't assume I can write a C# script, please)
I have used VB or C# scripts to accomplish this myself. Since you do not want to use scripts I would recommend using a different path for the project to flow. Have your success path lead to moving the file to completed and failure path lead to moving the file to failed. This keeps it simple and accomplishes what you are looking for.
I'm working with legacy tsql code that outputs to txt files.
For security reasons, I'm replacing these outputs with SSIS packages.
I've gotten most of them to work, but one particular one gives me the following error:
TITLE: Microsoft Visual Studio
Cannot create connector.
The destination component does not have any available inputs for use in creating a path.
The data flow itself is very simple. OLE DB Source runs an SQL command, then outputs to a flatfile source that points to an existing txtfile that was created by the TSQL.
Anyone know what the error means in regards to the available inputs?
Your SSIS toolbox is divided into 3 general groupings (pre 2012/2014)
Sources
Transformations
Destinations
A source has 1 to N output paths. Nothing can feed into a source. Things can only consume what a Source emits.
A Transformation does not generate* rows, it accepts rows from an upstream provider (either a Source or another Transformation). A Transformation has 1 to N output paths.
A Destination is the terminus for data. I'm not aware of any destinations that accept more than one input. It has one optional output path, Error.
Your problem, therefore, is that you are trying to route data into a Source. Change that to a Flat File Destination.
Replace the Flat File Source with a Flat File Destination task. Click on the RowCount task and drag the green arrow to the new destination.
Hi I have created basic SSIS package that reads data from Flat Txt file using comma separated and inputs into MS SQL database. Package is working alright but when there is no data in the flat file Then it displays message "No records found." when ever flat file has this message my package stops working as column mapping distracts. Any idea to solve this issue.
Note: Flat file is generated by some automatic tool I cant change it.
Sample File:
====================== Here is output ================
You can see Both Lookup Match and No Lookup are running.
you can add a data flow to count the records before the main data flow. Execute main only if there are more than one record on the flat file. The control flow would look like this:
Keep a separate flow when an error occurs and log into flat file
Refer to this for more details:
http://sqlknowledgebank.blogspot.com/2013/04/ssis-data-flow-error-handling.html
It is similar to exception handling in any of the programming lanaguages.
If the exception is unhandled , then package terminates abruptly.
Inorder to avoid that, we need to catch the exception and log it .
This avoids abrupt stopping of packages and it exeutes sucessfully.
I just need to update status of all the records which are not in the flat file so I used OLEDB command on the top of my package and updated status of all records in the table. Rest I kept my package as it is(without any changes).
At present I have source XML file, from which I am truncating some values using XSLT file. For this I am using “XML task” in control flow.
Then after getting the resultant file manually I am submitting the resultant XML file to XML source and then loading the data into an SQL table.
If there a better approach to do the same in one go ?
Novice to SSIS. So if possible could someone give example or link to any example to accomplish this
The SSIS Package can contain both control flow as well as one or more data flows. you need to include your both XML Task and Data Flow Task (having XML Source for loading data to sql table). Connect these executable and task in control flow using precedence constraints . This SSIS Package will be automated.
Saving Result from XML Task to file or variable.
In XML Task Editor,
Set SaveOperationResult to True
Set OperationResult\DestinationType either to File Connection or
Variable
Define New Variable or File Connection from Destination property or
select existing one.
In XML Source Editor, select "XML data from Variable" or "XML File Connection" and then specify details in the XML location accordingly.
