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 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 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?

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 had Packages in the past where I was looping through multiple Text files in a folder and loading into sql server tables.
Now I am asked to create a package which will loop through Multiple Excel Files in a folder and load them into sql server table.
I went through the following steps to create this package assuming it shouldn't be much different from what I have in other packages where it loops through multiple Flat file.
Added an Execute Sql Task, Truncating my staging table, A simple Truncate table statement.
Added a Foreach Loop Container. Selected Foreach File Enumerator and created a variable called File_Path with data type string.
Added a Data Flow Task.
Added an Excel Data Source. and configured the Excel Connection manager By selecting any one 'Excel' File in the destination folder. (At this point is configured correctly as it is not showing any red cross or warring messages.)
Then I selected the Excel File Connection Manager and in Properties windows Under Expressions, Selected Connection String property and Used the User Variable #User::File_Path.
At this point the Excel Data source is showing a Red Cross as it needs further configuration.
I have tried a few things Like changing the Data Access Mode from Table name to Table Name or View Name Variable, And passing variable #User::File_Path but it gives me the following error.
Can someone please have a look and advice where I am going wrong and how I can fix this? Any Advice or a pointer in the right direction is much appreciated.
Thank you.
You shouldn't use an expression on the ConnectionString property, but on the ExcelFilePath property.
I have searched everywhere for an answer to this so I am hoping someone out there can help.
I am trying to follow the steps laid out for importing data from multiple excel files in SSIS. I have several excel 2010 files in a directory and am trying to move them into a SQL Server 2008 r2 Database. I have followed all of the directions for doing this with a For Each (File) Loop. I have set the collections information and am using the User::Filename variable to pull back the Fully Qualified filename. The problem I have is that when I check the properties of my excel connection manager-->click on expressions-->modify excelfilepath by setting it to #[User::Filename], SSIS immediately overwrites the property with the new value which is blank (the first time). This then causes my package to fail during execution because there is no filename to go to in the connection.
I have set the delayvalidation property to True on the package, the dataflow and the excel connection and this does not fix the problem. I have also tried to put a fully qualified filename into the User::Filename variable during initialization and this does allow me to process a few files but then gives me a locking error when SSIS tries to re-read the file that I put in during initialization.
I have not found anything like this on the net yet...Hopefully, someone out there has seen this.
I would split this SSIS package into two. The master package would go as deep as the For Each File Loop, but would not include the Excel Connection Manager. The sub-package would open and process each Excel file. It would receive the Filename variable value via Configuration for a Parent Package Variable or similar.
This seems to have the effect of "closing" the excel connection after each file is finished.
I also prefer the OLE DB driver from the Access Database Engine over the native SSIS Excel connection.
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.
