It looks like you?re trying to use both stdin and stdout, but you really only need stdout here, since sqlite3.exe will accept SQL or sqlite3 shell commands on its command line after the database argument. You don?t need to feed it the commands over stdin. In fact, you don?t even need to use stdout, if you?re willing to leave it all to the command shell: cmd.exe /c sqlite3 Database.sqlite .dump | sqlite3 NewDatabase.sqlite Then replace Database.sqlite with NewDatabase.sqlite, optionally moving the former to a backup location first.
