I have a CSV file that I use a SSIS package to import into SQL Server. I am looking at the 'Flat File Source Editor' under 'Data Flow' and I see a list of 'External Column' with the matching 'Output Column'. If I have a new column in my CSV file, how would I add that to be included in the import? I don't see an option to add a new column in the Flat File Source Editor.

It is not the flat file source that you need to change, it is the flat file connection manager. Your source references a connection manager. You should see that connection manager listed in the 'Connection Managers' tab below the design surface. Edit the column list on that connection manager (or refresh from your source file). After doing that you should see the new column listed in the Flat File Source component.

I have a flat file source editor for CSV file.
In the flat file connection manager, I can see the whole rows are visible in the preview section of the connection manager but when I am running the package ,finds that it picks only subset of rows from the csv file flat file source editor.Flat file source editor is not picking the whole data.
Why not picking all rows and only subset of rows...
Thanks,

Using SSIS, uploading from a text file to SQL Server database table, I need to add the text file name as a column in the results dataset. I am able to create a flat file source, get the data from the file, load into an OLE DB Destination but I am missing the step to add the filename to the dataset.
Basic user using VS, mostly a SQL Production DBA but our developers said to create an SSIS package to upload the daily text file.
In your flat file source, right click on it and go to advanced properties. In the Advanced Properties editor, select the Component Properties tab and then under Custom Properties, there is a FileNameColumnName. Here I used SourceFileName
I attached a data viewer between my flat file source and the next component et voilà!
I have a Flat File Source that is reading data from a flat file. We have recently added a new column to this flat file.
The flat file data is inserted into a database table. To accommodate the new field in the destination component, I used the ALTER TABLE statement to add the new column to the table. That is the only change I have done.
Should the mapping between flat file and destination component automatically change? I do not see the additional column present in the flat file anywhere within the SSIS package.
How do I configure the additional column in the flat file within SSIS package so that flat file source can pass the data to the destination component?
If you added a new column to the flat file, you need to update the Flat File Connection Manager to reflect the new changes. Flat File Connection Manager will be present under the Connection Manager tab at the bottom of the package.
Sample scenario illustrated using SSIS 2012:
Let's assume that you have a flat file with columns StateCode and StateName.
When you configure the Flat File Connection Manager, you will see these columns configured under Advanced tab page as shown below.
If you modify the flat file to add an additional column, say by adding the new column named CountryCode.
The flat file connection manager will not contain the new column definition. You need to open the Flat File Connection Manager to add the new column or you could delete the Flat File Connection Manager and create a new one with the new flat file column definition.
You need to click New and select appropriate option to insert the column. You cannot move the column positions. So, make sure you select the right option to add the columns. Set the appropriate properties to define the column.
When you modify source or destination schema, it will affect the source and destination components within data flow task. You might see a warning icon on the component as shown below because the component is out of sync with the metadata information of the connection manager that it is associated with.
Double-click the component showing the warning and click OK on the editor to resolve the mapping issue.
Hope that helps.
When you alter the metadata of an underlying component such as a flat file or a database, SSIS doesn't automatically refresh all the available columns. You have to do this manually.
Open the source component's editor and navigate to the "Columns" properties (on the left) and verify all of your external columns from the flat file are there and are selected as output columns.
Repeat this process for the Mappings property window of your destination component. Verify all flat file columns are mapped to the proper destination column.
The simplest way of updating your columns in your flat file source is to reset the columns on your flat file connection.
Open Your flat file connection from connection managers
Select Columns (below General)
Click Reset Columns - this then includes any new columns.
Of course you need to be careful if you have made custom changes to the data types, et cetera.
I am trying to import multiple tab delimited files into a sql server table using a SSIS package. I set the flat file source and created a flat file connection manager but I was told I will need to create multiple flat file sources for this. This cannot be true right?
Is there not someway I can use a loop and the source folder directory location?
So long as the files are all the same structure, you'd use a for-each loop, of type file. Point it at the folder with the files in, and assign a variable to the file+path. Then use that variable as an expression on the flat file connection manager.
Here is a link that shows how to do this: http://www.sqlis.com/sqlis/post/Looping-over-files-with-the-Foreach-Loop.aspx
I like the layout and the graphical indicators used on that page.
I have an ssis package...which read data from fixed-column-width text file into DB table.
And I am modifying an existing ssis package.
I have a flat file source...and flat file cnnection. When I try to edit the flat file connection...using "flat file connection manager editor"..., under "general" part...even if I select different filename..it's not getting reflected.
OR...select the properties window of "Flat File Connection" - once I change connection string and click "save" of visual studio...it rollback
Help me please.
Pulling a useful comment into an answer...
It's possible that that Connection string (the file path, name) is set from an expression/user or project parameter.
To check, right-click the flat-file connection manager and go to Properties, then check Expressions to see if the ConnectionString is set from a variable such as #[User::MyFileConnectionString]
That would cause this behavior of it seemingly "un-doing" after you change it manually.
Is it possible you don't have access to the package itself? Right clicking on the file icon in the Connection Manager below and selecting 'Rename' and then renaming it right there and then saving the package should work.
