Create a STRICT table.

Require values compatible with declared column types.

SQL snippet.sql
CREATE TABLE tasks (id INTEGER PRIMARY KEY, title TEXT NOT NULL) STRICT;
INSERT INTO tasks (title) VALUES ('Read notes');
SELECT id, title FROM tasks;

Expected output EXAMPLE

1|Read notes

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. STRICT is available in SQLite 3.37 and later; supported type names are limited. The verifier uses a fresh SQLite file for each example.

✓ Verified

Tested on Ubuntu 24.04.5 LTS · · SQLite 3.45.1 · sqlite3 3.45.1-1ubuntu2.8

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.

Test input setup

These are the prepared inputs used by the test harness. See Details above for the prerequisites and how to run this example.

# No input files required.

Observed standard output

1|Read notes

Exit code: 0. Standard error: empty. Validation: Exact stdout comparison. System-dependent values above are one recorded run.

Additional assertions that passed

Checks recorded by the test harness. Where Python assertions are shown, browser cases use Playwright and simulator cases may inspect pin transitions: result.stdout is captured output, work is the temporary directory, and Path is pathlib.Path. The harness also imports json and csv.

Invalid fixture insert rejected by the database: strict_type_rejected
