This is #49 by @tao-io, with review fixes on top. Their 9 commits are unchanged. GitHub doesn't let maintainers push to a fork owned by an organization, so the fixes couldn't go onto #49 directly. Refs #48.

What #49 adds

See #49: a /sqlite entry with codecs, functions, positional ? binding, sqliteDialect (client transactions and savepoints) and d1Dialect (100 bindings, no interactive transactions), plus compile-time refusals for what SQLite lacks.

What this adds

Fixes, found by running the fuzzer (#118) and the core builder suite on SQLite and D1:

• LIKE escapes. SQLite has no default LIKE escape, so like("org\\_1") matched a literal backslash and never org_1. The dialect now writes ESCAPE '\', so \ escapes the same way on every dialect.
• U+0000 is refused. SQLite drivers end text at NUL: node:sqlite reads 'a' || char(0) || 'b' back as 'a', whether bound or literal. feat: add SQLite and Cloudflare D1 query dialects #49's own NUL test failed on Node 24 (our mise.toml version) for this reason. The builder now refuses such a string at compile time instead of storing a value that reads back cut short.
• Exact fractions. SQLite parses some decimals to a neighbouring double, both as a literal and through json_extract (1.23456789e-95). Fractions in expressions are now bound instead of written as text.
• Amount > 9.75 compiles. It was refused because SQLite.integer only encodes whole numbers. It now behaves as on Postgres and ClickHouse; inserting a fraction is still refused.
• Docs. docs/sqlite.md now states that SQLite's LIKE ignores ASCII case.

Tests:

• tests/core.sqlite.test.ts runs every shared core case on node:sqlite and on a local D1 binding (Miniflare), with SQL snapshots for both. This is the "shared builder suite" criterion from MySQL / MariaDB dialect #53/Support SQLite and Cloudflare D1 through the existing dialect and Effect SQL APIs #48.
• tests/fuzz/dialects/sqlite.ts registers sqlite and d1 with the fuzzer: query plans against the reference model, literal round-trips for every SQLite column type, compile invariants and hostile values.
• New core cases pin LIKE escapes and LIKE case on every dialect. ILIKE gets its own case, so patterns-and-lists now runs on SQLite too.

Verification

• bun run typecheck: pass.
• bun run test with ClickHouse 26.8.2.7: 64 files, 1,219 tests passed, none skipped. Doc citations, export catalogs (151 /sqlite) and doc examples ok.
• Every fuzz property at FUZZ_SCALE=20 on all six targets: 101/101 pass.
• bun scripts/check-package.ts: ok.

Decisions

• like stays SQLite-native (ignores ASCII case), and the difference is documented and pinned. ILIKE stays refused, as feat: add SQLite and Cloudflare D1 query dialects #49 chose.
• The new refusals die with QueryBuilderDefect, as row locks and FORMAT already do on main.

Second round: gaps closed (after review)

• Timestamps in SQLite's own text form. SQLite.timestamp stored ISO text (…T16:28:54.750Z), while SQLite's own functions write YYYY-MM-DD HH:MM:SS. SQLite compares text by bytes, and ' ' sorts before 'T', so a row a DEFAULT had just stamped was not "later than an hour ago": wrong rows, no error.
  • It now stores YYYY-MM-DD HH:MM:SS.SSS in UTC, the form strftime('%f') and datetime(…,'subsec') write.
  • It reads that form and ISO; zoneless text is UTC.
  • Values outside years 0000–9999 are refused with a typed error. new Date(8.64e15) used to be written as garbage.
  • The literal fuzz builds its reference row with SQLite's datetime().
• integer refuses values past 2^53. D1 rounds such an INTEGER to a different JS number, which then decoded silently. It is now a decode error.
• The integer > 9.75 rule is a dialect flag (integerComparesFraction), so a custom profile spread from sqliteDialect keeps it.
• SQLite and D1 now run the write and union fuzzers from test(fuzz): fuzz unions and writes on every dialect #122: INSERT/SELECT, ON CONFLICT, UPDATE, DELETE and RETURNING against a model, and per-cell DEFAULT refused.
• The D1 test helper retries transport errors only (Miniflare "fetch failed" under a soak).
• Changesets match the code (CodeRabbit on feat(sqlite): table DDL — columns, keys, indexes #50).
• Verified against ClickHouse 26.2.19.43 and 26.8.2.7: bun run test (1,239 tests on this branch) and every fuzz property at FUZZ_SCALE=20.
