## What's wrong
`toSQL` renders numbers with `toString()`, so `NaN` becomes `NaN` and
`Infinity` becomes `Infinity`. SQL reads those as column names:
```ts
await table.update({ values: { price: NaN }, where: "id = 1" });
// Error: Invalid input, Schema error: No field named "NaN". Valid fields are id, price.
```
`Infinity` and `-Infinity` fail the same way. The only workaround today
is `valuesSql`.
## Fix
Emit `CAST('NaN' AS DOUBLE)`, `CAST('Infinity' AS DOUBLE)` and
`CAST('-Infinity' AS DOUBLE)` for these values. Finite numbers render as
before.
## Tests
- `__test__/util.test.ts` adds `toSQL` cases for `NaN`, `Infinity` and
`-Infinity`.
- `__test__/table.test.ts` adds "should let me update float values to
NaN and Infinity", which updates a float column and reads the values
back.
- On `main`, the new cases fail with `No field named "NaN"`.
- With the fix, all of `util.test.ts` and `table.test.ts` pass (344
tests). These were run against the published
`@lancedb/lancedb@0.40.0-beta.11` native binary.
- `biome check` is clean on the changed files.
The Python SDK has the same issue in `value_to_sql`. That fix is in
#4326.
The fix was found and written by an AI agent (Breken) and checked
against the tests above.
