Cross-database queries in SQLite (and weeknotes) I released Datasette 0.55 and sqlite-utils 3.6 this week with a common theme across both releases: supporting cross-database joins. SQLite databases are single files on disk. I really love this characteristic-it makes them easy to create, copy and move around.
All you need is a disk volume you can create as many SQLite databases as you like.Ī lesser known feature of SQLite is that you can run queries, including joins, across tables from more than one database. The secret sauce is the ATTACH DATABASE command. Run the following SQL: ATTACH 'other.db' AS other Īnd now you can reference tables in that database as other.tablename. You can then join against them, combine them with UNION and generally treat them as if they were another table in your first connected database.
I’ve wanted to add support for cross-database queries to Datasette since May 2018. It took me quite a while to settle on a design-SQLite defaults to only allowing ten databases to be attached together, and I needed to figure out how multiple connected databases would fit with the design of the rest of Datasette. In the end, I decided on the simplest option that would unlock the feature. Run Datasette with the new -crossdb option and the first ten databases passed to Datasette will be ATTACHed to an in-memory database available at the /_memory URL. $ sqlite-utils first.db -attach second second.db ' select * from table_in_first union all select * from second.table_in_second ' Here’s an illustrative example query that performs a UNION across the sqlite_master metadata table in two databases: The demo now exposes two databases using this feature. This defaults to returning results as a JSON array, but you can add -csv or -tsv or other options to get the results back in different output formats.

It’s extremely easy to setup, buildable as a single C file with libraries existing for basically all common programming languages. It doesn’t need any server setup or configuration since the SQL logic is run in the host process, and the database consists of only two files you can easily copy or move around. You can still connect to and query the same database concurrently with multiple processes, though only one write operation can happen at the same time. Run these every time you connect to the DB SQLite is often seen as a toy database only suitable for databases with a few hundred entries and without any performance requirements, but you can scale a SQLite database to multiple GByte in size and many concurrent readers while maintaining high performance by applying the below optimizations.
