Programmatic SQLite Queries in PowerShell
Programmatic SQLite Queries in PowerShell
This will be a real quick one. After watching a short video on the history of SQLite and its applications, I decided to tinker with it a bit. It’s a very easy database system to work with.
I found that the sqlite3 binary accepts a string containing a command as an argument and realized that you can use this in conjunction with PowerShell to programmatically build and execute queries.
Base Concept
I knew that you got into the SQLite command line by running sqlite3 and then you could run SQLite queries and dot-commands from within the CLI. A quick bit of research told me that you can also specify a both a database file and a string after the binary name to run queries against the database without keeping the SQLite CLI open.
At it’s foundation, its as simple as doing:

So where does this go from here? Here’s my train of thought from the other day.
Can I pass the string in from the pipeline?

Yep, that worked. Selecting information is pretty easy.
What about doing inserts?

That worked as expected, too.
Building Queries
Next up was programmatically building queries…

This also works! There’s some goofiness with making sure you’re including the necessary single-quotes and commas, but it works. And there’s very likely a better way to do that. This was just a cursory discovery. So that’s pretty much it. Nothing complicated and nothing inherently revelatory, but something I stumbled onto and found interesting. Maybe I’ll have a cool use case for this some day. Maybe you do?
If you found this helpful or have a neat case where you’re using PowerShell to build SQLite queries, I’d love to hear from you on BlueSky ( @griff.systems). Thank you!
