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.

I want to open a ".dtsx" file as a raw file or an xml file (doesn't matter which). Is this possible in SSIS? Not from what I can tell, but I wanted to see if someone else has run into this before.
Edit #1:
My ultimate goal is not to view the xml, but to import the xml in all the packages as text data and search the xml that way. I have about 200-300 packages to search.
To view the XML of your package right click the package and select View Code from within SSDT. This will open the XML for it.
I would take copies of all the packages you want to search and put them in their own folder. Create a Foreach File Loop container, point it to your folder, and give it *.dtsx as the file wildcard. Make sure you set a variable to capture the fully qualified path to the file.
Inside the Foreach Loop, use your path variable as the connection string to a Flat File Connection. Configure the Flat File Connection with Ragged Right as the Format and with Tab as the row delimiter. You should get a single row with a single column. In the Advanced tab of the Flat File Connection Manager, set the DataType to Unicode text stream.
You now have the raw text as an NTEXT field. If you import this into an NVARCHAR(MAX) field in a db table, you'll be able to use SQL's xml processing, which I believe is what you're trying to achieve.
I am working in BIDS. I have an SSIS package that loops over all files in a given directory and imports all of them to a table. So, my control flow has a Foreach Loop Container with a Data Flow Task inside of it. The Data Flow Task goes straight from a Flat File Source to an OLE DB Destination. Because the directory can change, I have made the Foreach Directory dynamic (i.e., I gave it a package variable, which I can change when the directory changes). The Files field has something like stuff*.pip, such that all files in the directory that match this pattern get imported. The Variable Mappings tab has a file name variable, which is the same variable used in the Expressions of the flat file connection manager.
When I originally set up the flat file connection manager, I had to point it to an already existing file to pick up the file's metadata. I then changed the file connection manager to dynamic (i.e., I added a file name variable in the Expressions property) such that the Foreach Loop Container will pick up all files (that match the pattern).
Since then, the metadata on the file has changed. So, when I open the solution file, it throws a warning on the Flat File Source in the Data Flow Task. To resolve this, I have to temporarily change the flat file connection back to a hard-coded path such that I can change the metadata on the new file. I then make it dynamic again (i.e., use the file name variable in the Expressions, which overrides the hard-coded file path). (Finally, I double-click on the Flat File Source in the Data Flow Task to automatically update the metadata in the Flat File Source.)
Is this the correct way to update the metadata on a flat file? It seems a bit clunky to me.
You can prevent this error from occurring by editing the properties on the Flat File Manager and setting ValidateExternalMetaData=False.
You may also need to set DelayValidation=True on the Data Flow Task that contains the Flat File Manager.
This will prevent the warning - but if the file's metadata changes for some reason (columns change, data types change) and you do not remember to update the metadata then you will get a runtime error.
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.
I have an XML Source task which requires a XSD to generate my data flow work from my XML files in SSIS. How can I embed the XSD file within the SLN/DTSX project and have it be referenced correctly? It would seem the best case would be to have the XSD source inside a variable, but I dont see where I can do that given the XML Source data task
Using Project Deployment model it is possible to get the miscellaneous files bundled with the deployment. However I want to use the Project Deployment model. That model does not allow for files other than the ispac file. To get around the problem using this following post as reference SSIS dynamic xsd source file
Effectively you store the XSD within a available sql server database as a XML schema, use a dataflow to query for it, and store it in a RAW FILE. Then save the RAW file to disk for future use. Very Effective
