I tried to create a SSIS package to input excel file into database.
The excel file has dynamic name, and also i need to add filename into the database as well.
What I'm trying to do:
use for each file loop to set a variable called FileFound, with the value of
the filename (with full path)
set connection for the input file with above variable
use data load to load the excel to db, with above connection.
I got error saying the connection is invalid.

can you please check?

There is step you missed when using dynamic file names in a foreach loop. You need to set delay validation property of the dynamic source (in your case the Excel Conn) to TRUE.
The package tries to validate in pre-execute phase unless you delay it.

I have an SSIS solution where depending on a parameter, it launches the extraction of different databases, each in a different file, and the name must contain the date of the extraction so we can't hard code the name in the Destination wizard, I must use a variable where I concatenate the date to a file name, and I have to use that variable as the file name. But the destination wizard only seems to let me write plain text.
Any idea how I can do this ?
Select the connection manager in the Connection managers bar. Go to the Properties Pane and find the "expressions" option. Click the ellipsis in the adjacent blank window to open a new window.
Find "File Name" or "Connection String" in the drop down, and then in the expression, put the name of your variable.
If the file may not exist before the package is run, ensure you enable delay validation on the connection manager too.
I have created an SSIS project to load data from Excel file source. I am using foreach loop to take all Excel files from a selected folder. The loop seems to take the first file, but when it takes the next file an error occurs. It says that it needs a new metadata. The Excel source have the same file format and the same header (only one column data).
I am looking for an advice.
Sometimes excel will actually have more columns than it appears. Two ways to check this:
1. Save as csv and see if you have extra ,,, at the end of each line.
2. Create a quick test package and connect to the excel file and verify that the source has only one column.
I need to create a SSIS Package which will run daily and export a table's data into a directory. The Exported excel have a predefined format. So I have used a template excel. (Excel File with Column Headers only)
Here are the steps I followed:
Created a variable Filename with holds the location and name of the excel to be generated
(based on current date value)
Added a File System Task in Control flow. Give Source as Template Excel and Destination as the Filename variable.
Added a Dataflow Task in control flow and connect it with File System Task.
In Dataflow Task, added a OLE-DB source and configure it with the source table (the table data needs to be copied into the excel )
Added a Excel Connection manager and changed Excel File path property to filename variable.
Added a Excel Destination and configure it with Excel Connection manager.
set Delayed validation true in Data flow task and Executed the package.
Control Flow:
Data Flow:
The Package is running successfully and the excel file also get generated in the desired directory. But the excel file skips around 19000 rows copying data after that . why it is happening?
Can any one help me to solve the issue.
Thanks for the help
It is possible that the file is already formatted , and that lines are down at the bottom...often excel jumps or add lines if you do not delete the lines already used even if empty...we must also consider strange events!
I am setting up a For Each File Loop to upload all the text files in a folder and create a DB item with the same name. This however is causing me to get the above error. As you can see from the two screenshots below, I have (I think) set the Connection Manager for the OLE DB Destination object up correctly, but the error remains. Does anyone know why I am getting this and where I am supposed to specify a table name if a declared variable is being used for the looping?
In your variable definition (User::FileFound), you have to specify the sheet name in the Excel workbook you used to set up your Excel Connection Manager (e.g. 'Sheet1$').
You're presumably changing the value of the variable at some point in your For Each File loop process, which makes sense, but at design time, you have to specify a real sheet name.
In your Control Flow, click on your data Flow Component
On properties, change the 'DelayValidation' to 'True'
I would like to create a text file with some data i am manipulating in a script component and write it to a text file. i know how to write it to an existing text file, but what i would like to do is create the text file programmatically so i can name it textfile(TodaysDate).txt
How can i do this??
You can call File.CreateText(someString).
This method returns a StreamWriter which can be used to write to the file.
Remember to close the StreamWriter usinga using statement.
If you start with a sample of the text file that you want stored somewhere, you can use a file system task to copy the sample file to the correct name (make sure you copy so that it's still there for tomorrow). Then use an expression to set the file location in the file connection manager.
