I am using VS2017 and SSMS 2017 and imported a CSV file in FLAT FILE option in Data Flow tab in SSIS and also created anADO NET SOURCE database connection through my local server that stores the data in my database. But when am trying to create a connection between FLAT FILE and ADO NET SOURCE, by dragging the blue arrow from file option to ADO NET option, am getting this error. Can anybody provide some input on how to get rid of this error?
enter image description here
You are attempting to route the flat file source into another source component, which cannot be done. Did you mean to route the data into a destination?
Error is that you have connected Source to Source.
Fix it by connecting Source to Destination, so that the package can build successfully.
Replace your ADO.NET SOURCE with ADO.NET DESTINATION and this error will be corrected.

I have an SSIS package that is to load multiple Excel files using the For Each Loop Containter. As soon as I add the variable in the Excel Connection manager in expressions, under ExcelFilePath Property it throws an error in the Excel Source Package:
An OLEDB error has occurred 0X80004005. The MIcrosoft Access
Database Engine cannot write to the file "C:..."
It is already opened exclusively by another user or you need permission. I had to already download the 32bit Extension to be able to view the Excel files. I've followed many guides on how to do this, and it always ends up in the same result. Delay validations are set to True. Any idea how to fix?
I have multiple packages for each location site and each site contains 5 other sub sites for which data has to be populated every month. Hence I have approx 20 excel files as a source data for which the excel file acts as a source and I need to create an excel destination. Because of so many excel file as a source I have multiple Excel connection Managers (Source + Destination) across my various packages.
The source file name and the location will change everytime and so I was thinking to automate the file path via parameter. I follow the steps mentioned in the article: https://blogs.msdn.microsoft.com/sqlgardner/2015/06/18/ssis-tip-using-a-file-path-parameter-for-multiple-flat-files/
I followed every step but I got the error when I open the excel file (source). Below is the error snapshot:
Can someone guide me what exactly I am doing wrong here?
Looks like you're using an expression on the excel connection manager "ConnectionString"
property. When that property is changed to just a file path that isn't a valid connection string for that type of connection.
With excel file connections it's a little different and you'll want to use the ExcelFilePath property, which in turn is used by the connection manager when building out the connection string.
With Flat File Connections, yes you would use the ConnectionString property, Excel Connections, slightly different, use the ExcelFilePath property.
I'm having an issue exporting a large dataset (500k+) to Excel via SSIS, where the output file ends up with 0 rows exported. Before saying that I shouldn't be exporting that many records to Excel, let me state that I know and normally wouldn't. Accounting does not want a CSV and is unwilling to open a CSV in Excel.
Using Visual Studio 2012 SSDT, here are the components involved.
Execute SQL Task -> Creates the empty file with headers
Data Flow Task ->
OLE DB Source -> SQL Query
Excel Destination
While the package is running, you can see records flowing from the source to the destination. The package completes without error, but when you open the file, it's empty. The only thing in there is the header.
If I select the Top 1000 records and export to Excel, it works as intended.
Some things I've tried:
Export to Excel on the network
Export to Excel locally
Export to CSV to Excel on both network and locally
Export to Ole DB Destination using Office Access Database Engine 12.0 with "Excel 12.0" extended properties.
Tried running as different users
All with the same outcome.
Can anyone provide any insight into why this may be happening and how to proceed?
We experienced a similar behaviour, when runnig the ETL in a SQL Server Agent job. Debugging it in Visual Studio, worked, however. So I do not know, whether this solution applies to you.
The reason was that the user, under which the package ran, did not have access to C:\users\Default.
I found this out by using sysinternals process monitor.
I was inspired by that post: Empty Excel File permissions issue: SSIS Excel Destination buffers large record sets through C:\Users\Default

I got this SSIS package working this past December. It only runs on Friday mornings. Last Friday it failed with this error message:
Package:Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft Access Database Engine" Hresult: 0x80004005 Description: "The Microsoft Access database engine cannot open or write to the file '\\ServerShare\IT\Reports\Export Templates\YoderReport.xlsx'. It is already opened exclusively by another user, or you need permission to view and write its data.".
I've checked out a couple of other questions that were similar, but they did not answer my question. I have checked to make sure that no one has that file open.
The file in question is a template that is copied over then populated, so no one should have it open, to begin with.
I've tried changing the RetainSameConnection to True, but no difference. I have run it in debug mode, and it works fine.
Anyone got any ideas how to clear this up so it runs automatically again?
UPDATE
After some more testing, it appears that the file is getting the data, but isn't being copied. Here is what I have setup:
I have a File System Task that copies a template from my template
folder to my Export folder.
Then I have a Data Flow Task
Begins with a OLE DB Source that runs a SQL script to pull data
Runs a Data Conversion to update a couple of fields to the correct format
Excel Destination is used for the output. (This is the template that was copied to the Export folder
There is also a Flat File Destination just in case there are any errors
Then back to the Control Flow with another File System Task, this one moves the file from the Export folder to its final destination on a shared drive
When I run this from VS 2015 it works fine and creates the file. When I run this from the SQL Agent job it fails with the above error message. The only thing that I can think of is that in the Data Flow Task the Excel Destination isn't releasing the file before the final File System Task tries to copy it? But if that is the case, why did that just start happening now?
I think that there is a problem in the filepath, as you can see the file path start with one single backslash:
\ServerShare\IT\Reports\Export Templates\YoderReport.xlsx
Maybe it should start with double back slash \\ if it is on the network
\\ServerShare\IT\Reports\Export Templates\YoderReport.xlsx
Or the Partition is missed --> Incomplete path
Check the way that the file path is provided to the connection manager (if you are using expressions)
Also based on this microsoft article, there is two possible causes:
You must have permission to read data in the specified file in order to view its data. To change your permission assignments, see your system administrator or the table or query's creator.
You tried to open the indicated file exclusively, but another user already has the file open.
Looks like an access issue. Ensure that the Agent Service Account is running with full rights to the network share path. Maybe you can try with your credentials on the Agent Server.
Also, Ensure that your Excel destination connection string supports .xlsx.
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=c:\path\xxx.xlsb;Extended Properties="Excel 12.0;HDR=YES";
Changing “Excel 12.0” to “Excel 12.0 Xml” will tell the provider to output in .xslx format instead.
I am totally new to the SSIS. I have a requirement to create a text file on specified location and write the data in it which is selected from SQL table.
How to do that?
Is there any example which will help me?
The below steps should help you to get a basic SSIS package working:
Create new Integration Services Project in Business Intelligence Development Studio. There should be a default SSIS package in it called Package.dtsx. Open the package.
In the bottom of the screen, there should be an area for connection managers. Right click on it to get a list of different connection managers.
Click on New OLEDB Connection. This will be the connection manager for your source database. Set the data source (server or instance name), authentication mode and credentials and the initial catalog (database name).
Again right click in the connection managers area and select New Flat File Connection.This will be the connection manager for the destination flat file. You can create a text file (.txt or .csv) and add in the headers for your data e.g. EmployeeID,EmployeeName,EmployeeSalary. Check the "column names in the first data row" checkbox to make sure your headers are identified as such.
Now select a Data Flow Task and drag it to the Control Flow screen.
Open the Data Flow tab. Drag 2 items from Toolbox to the screen - OLEDB Source and Flat File Destination.
In the Source, use the OLEDB connection manager created earlier. Then change the Data Access mode to SQL command. Now you can type your own command to select data. Make sure that the header data in your flat file is the same as the column headers from your select query.
In the Destination, use the Flat File connection manager created earlier. Go to the Mappings section and map the columns from your query output to the headers in your text file.
Now save and run the package. You should see that the destination text file is populated with data from your query.
