I have one temp folder C:\Mydata inside that i have .csv files with name
demo1.csv demo2.csv…etc
Now I want to insert data from all those files into database table
for this I have taken Foreach Loop Container in the property Directory I mention
C:\Mydata
inside Foreach Loop Container taken a Data Flow Task in that Flat File Source is there in the connection manager property in file name what should I mention, so that it will traverse through all folder and all files whose extension is .csv
I did like C:\DEMO\*.csv which is giving me error :
no file found path is wrong
From what i interpreted, your issue was assigning the resulting file from the foreach to the connector.
To do that you need to assign the filename from the Foreach to a variable.
The first step to be taken is to create the variable. To do that you need to activate the “Variables” window:

Then you need to create a new variable of type string and rename it.
For more information on SSIS variables and how to create them, see http://msdn.microsoft.com/en-us/library/ms140216.aspx
Now you need to assign the new variable (in this case i named it “filename”) to the foreach loop:

NOTE THAT WHILE THE OPTION “Name Only” IS SELECTED IN THE FIRST WINDOW, IN YOUR CASE YOU PROBABLY WANT “Fully Qualified”!!
The screenshot was taken from a working project i have and i am using only the name (Name Only) as opposed to the full path (Fully Qualified)
After doing that you need to assign that variable to your flat file connector using expressions:
