i am getting two text file having same structure with different name every time.
and i need to load the file everytime to table. how can we configure our connection manager
to load data from different file name to a table. Please any one suggest.
You can use a FileName variable in your Flat File Connection Manager's ConnectionString property and dynamically set it to the different name(s) and achieve this.
Here's a detailed article that shows you step-by-step on how to accomplish this.
SSIS - Dynamically set Flat File Connection Manager

I am working with a scenario where I have one azure file storage account in which I have different folders, each contains the *.csv file. I want to load each *.csv file in different Azure SQL Database tables dynamically by iterating over the my RootFolder.
The problem I am facing is my *.csv file contains more columns than my destination. When copy activity gets triggered following error is encountered:
You could make your dataset schema as expression. And then use GetMetadataActivity to get schema of each file.
I have to create a job which imports data from .csv file into database table everyday. I have created the job and it works fine as long as the filename is same.
The file that comes in everyday has a different name, so i am trying to set up dynamic flat file connection. As i have only one file to load everyday i am not trying to use For Each Loop Container and also, i am not good at script task.
I was trying to see if there is any other way to achieve this using SSIS.
I have created a variable for my path "C:\Daily Files\" as #[User::MyFilePath]. I am then using this variable in the ConnectionString Expression property of the Flat File Connection Manager.
But it does not work. I get an error saying the Cannot open the datafile.
Can someone tell me what am i missing here?
If you need to create a connection manager to a file that changes name everyday, you will have to write some kind of expression to do so. On the other hand, the easier way out is to use the For Each Loop container as it does not care what the name of the file is as long as you give it *.csv in the qualifying field.
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 created a package to fetch data from two SQL Server tables, and using merge join combined this data, then stored the result into an Excel destination.
The first time it works fine. The second time it stores repeated data in the Excel file.
How do I overwrite the Excel file rows?
Yes, Possible!
Here is the solution:
First go to your Excel Destination Click to New Button next to Name of Excel Sheet, copy the DML query inside.
Then put an Execute SQL Task into your Control Flow and connect it to your data flow that contains Excel destination. Set the Connection Type To Excel, Set the Connection to your Excel Destination's Excel Connection Manager, go to SQL Statement and type :
Drop TABLE `put the name of the sheet in the excel query you just copied`
Go
finally paste the query after it.
It is all you need to do to solve the problem.

Yes, Possible!
Using SSIS we can solve this problem:
first of all, crate an Excel format file (Structure Format using Excel Connection Manager) at one location as a template file. Then create a copy of that excel file using FILE SYSTEM TASK in another location and make sure that SET OverwriteDestination=True. Finally, using a data flow task, insert data into the new copied file. whenever we want insert data, it will create a copy of the template excel file and then load the data.
Unfortunately the Excel connection manager does not have a setting that allows overwriting the data. You'll need to set up some file manipulation using the File System Task in the Control Flow.
There are several possibilities, here's one of them. You can create a template file (which just contains the sheet with the header) and prior to the Data Flow Transformation a File System Task copies it over the previously exported file.
The File System Task (MSDN)
For Excel it will append data. There is no such option available for overwriting data.
You have to delete and recreate the file through the File System task.
Using a CSV file with flat-file connection manager would serve your purpose of overwriting.
The best solution for me was using File System Tasks to delete and recreate the Excel files from a template.
What I was trying to do was to send every employee a report with Excel attachment in the same format but different data. In a foreach container for each employee, I get the required data, create an Excel file and send a mail with the Excel file attached.
I first:
Create an Excel template (manually)
Create an original Excel file to be used (manually)
Then in the foreach container:
Delete the original file (SSIS File System Task )
Copy the template as the original file (SSIS File System Task)
Get the data from SQL Server and write them to the original file (SSIS Data Flow Task)
Send the mail (SSIS -> SQL Stored Procedure)
