To do this, open DB Browser and choose “New Database” then navigate to where you want your file to be stored, name it, and save it (be sure to choose “SQLite database files” as the file type). Next, you will actually create a new database using DB Browser for SQLite and import your data into it. There is no need to include an id column, since the backend will take care of that for us.Īfter your spreadsheet is complete, save it as a CSV file. The first column of your spreadsheet should be the attributes you want in your table, and it’s important that the headers follow appropriate conventions: snake_case and lowercased. For me, this part involved a lot of copying and pasting (though I happen to occasionally like some mindless, repetitive busywork). If SQLITEOMITTRIGGER is defined but SQLITEOMITFOREIGNKEY is not, then SQLite behaves as it did prior to version 3.6.19 () - foreign key definitions are parsed and may be queried using PRAGMA foreignkeylist, but foreign key constraints are not enforced. The first step, of course, is to model your database, preferably in Excel or another spreadsheet-creation software. Finally, though, I stumbled upon a couple resources that helped me create exactly what I was looking for, and I have detailed my final process here for anyone who finds themselves in a similar situation. A lot of my initial research pointed me toward Python scripts and other workarounds that seemed too complicated for what I needed or outside of my current capability. However, those methods seemed more for parsing data and still required manual entry for each record. I knew there had to be a way to populate a database from a CSV file or similar, since we had seen examples of class methods such as create_new_from_csv. So, when I found myself needing a pre-populated database of over 6,500 records for a recent project, I had no idea how to go about it. However, despite how much I have learned in the past two months, my experiences keep reinforcing just how much more there will always be to learn, and a recent project gave me the opportunity to expand my knowledge outside of my regularly scheduled schooling.įor most of my backend learning, the databases we had been working with maxed out at about 50 records, and were created using Rake migrations and populated via Ruby and Active Record’s. Apparently, I have very recently reached the point in my coding education where I can consider myself a “fullstack” engineer (though I use that term very lightly). To add to what Donal said, note that SQLite3 will happily create a Schema that contains unresolved foreign keys, and also that it may start with foreign-key checking turned OFF (depending on how it was compiled).
