I want to change the derived column's length in my SSIS package from 8 to 100 How can I do that?
To increase the length of a derived column or generally change the type, you need to explicitly cast it
Current
@[User::Inp_FileName]
Revised
(DT_WSTR, 100) @[User::Inp_FileName]
Cast the Variable Inp_FileName to a data type of unicode string, length 100.
