## Interpretation

- Choose a snapshot matching the target engine and build. The default is captured from the published Haybarn WASM package used by the browser playground. Historical native snapshots are also available.
- Availability is an observation in the recorded build and extension profile, not a guarantee of support in every installation or in WASM.
- Types and descriptions are declarations from duckdb_functions(). Binding can specialize result types. Null means not supplied by the catalog; do not invent defaults, optionality, argument mode, or table output columns.
- Raw parameter arrays preserve catalog order for scalar/aggregate/macro functions. Raw table arguments are alphabetical. Use callingConvention for engine-confirmed positional order and named arguments; null modes are unrecorded. Named does not mean optional. Macro defaults and special named variadic behavior are not supplied by duckdb_functions().
- Catalog examples are source material and may require data or extensions. runnableExamples contains separately verified SQL for the pinned WASM package; sample-data adaptations and guide examples are labeled separately.
- Guide annotations and recipes are separate editorial content. The browser runner always uses Haybarn WASM 1.5.5-rc3, independently of the documentation snapshot.
- All URLs beginning with / are relative to the origin hosting this document. Exports require no JavaScript, cookies, API key, or browser engine.

## In other engines

### BigQuery: safe_divide()

Uses / as part of a larger rewrite.

BigQuery:

```sql
SAFE_DIVIDE(x + 1, 2 * y)
```

Haybarn / DuckDB:

```sql
CASE WHEN (2 * y) <> 0 THEN (x + 1) / (2 * y) ELSE NULL END
```

### Snowflake: div0null()

Uses / as part of a larger rewrite.

Snowflake:

```sql
DIV0NULL(a - b, c - d)
```

Haybarn / DuckDB:

```sql
CASE WHEN (c - d) = 0 OR (c - d) IS NULL THEN 0 ELSE (a - b) / (c - d) END
```
