Group by more than one field.
SQLite: Each distinct combination of grouping fields produces its own row.
CREATE TABLE events (region VARCHAR(10),kind VARCHAR(10));
INSERT INTO events VALUES ('east','read'),('east','read'),('east','write'),('west','read');
SELECT region,kind,COUNT(*) FROM events GROUP BY region,kind ORDER BY region,kind;Expected output EXAMPLE
east|read|2 east|write|1 west|read|1
Details
Requires SQLite 3.40 or later. Run with sqlite3 demo.db in a scratch directory. Result rows below use | between columns, without headers; client display formatting may differ. Each distinct combination of grouping fields produces its own row. The CREATE and INSERT statements provide all input data. Run the complete example in a fresh scratch database or schema.
Tested on Ubuntu 24.04.5 LTS · · SQLite 3.45.1 · bash 5.2.21-2ubuntu4; coreutils 9.4-3ubuntu6.3
Test inputs, results and environment
The exact published code ran in a dedicated Linux test container with prepared inputs. Snippet process uid 65534 with a read-only root filesystem and temporary working files. Networking disabled. Fixtures and output records are isolated from the application database. Testing covers this example and its stated checks, not every input, operating system, or runtime version. The Linux container shares its host's kernel; this is not a native Windows test.
