Input File Question

Question

Hi, all!
I have an input file (InputFileA) that is sent to me from a third party.  I have to load the file into a Table (TableA) and also include, with each row that is loaded, the name of the file from which it came.
EXAMPLE:
InputFileA looks like this:
Number  Amount
000001  1200.00
000002  2400.00
TableA (columns: NUMBER, AMOUNT, FILENAME) should have the following inserts done:
NUMBER: 000001
AMOUNT: 1200.00
FILENAME: InputFileA
NUMBER: 000002
AMOUNT: 2400.00
FILENAME: InputFileA
Can anyone offer any advice as to how I can extract the filename and then insert it into the Table for each row that is inserted from InputFileA?
I'm new to SQL Server (originally a DB2 guy) and I don't have much of a programming background, so I'm kind of stuck on this one.
Thanks in advance and hi to everyone!

Assuming you're using SSIS for transfer you can set it up as below
1. Add a ForEachLoop with file enumerator pointing to file location. Use a variable inside to fetch filename of files found (@[User::FileName]).
2. Add a data flow task inside loop with flat file source pointing to your file and set an expression for connection string to point to your dynamic file. For this select connection manager,  right click and select properties. Expand expression and
set an expression for connectionstring property to  point to @[User::FileName] variable.
3. Add a derived column task, add expression as @[User::FileName] and choose add as a new column option and give it name FILENAME
4. Add OLEDB Destination to point to your table and map columns from source file to table columns and FILENAME column created above to FILENAME column of the table
Execute it and you'll get your desired output.
