title: sqlite append two tables from two databases that have the exact same schema
body: <p>I'm writing data into an sqlite database, but because the data set is very large, I'm splitting the process into five pieces. As a result, I'm writing to five different sqlite databases at the same time, each having the same column names, and in the end, I want to append the five tables in the five databases together into one table. What is the way to do this?</p>
