title: Fastest Way merge two SQLITE Databases
body: <p>I have 3 SQLite DBs, each having exactly the same set of 7 tables with respect to table structure. [They are Log Dumps from 3 different Machines].</p>
  
  <p>I want to combine them into one SQLite DB, having those very same 7 tables, but each table should have the combined data from all the three DBs. since I want to run queries across the 3 of them.
  What is the best, fastest way to do it. </p>
