  • From Resources under Main Menu in Interact 2 go to Assignment 5 Folder
  • Copy sqlite3.exe and cmd.exe files from the Assignment 5 Folder into a folder in your machine\
  • Copy a5.txt from the Assignment 5 Folder into the folder in your machine where your SQLite file is located
  • From the SQLite Command Prompt execute the a5.txt script. To do this, at the SQLite Command Line type .read a5.txt [to create the tables you will use to answer this assignment’s questions]
  • At the SQLite Command Line type .headers on
  • At the SQLite Command Line type .mode column
