## 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.

## Guide recipes

### Give your timestamps a rhythm.

Group events into calendar months with date_trunc. The same pattern works for days, weeks, and years.

Intended runtime: Haybarn WASM 1.5.5-rc3. Per-example execution verification: not recorded in this export.

```sql
SELECT
  date_trunc('month', sold_at) AS month,
  sum(amount) AS revenue
FROM (VALUES
  (DATE '2026-06-03', 120),
  (DATE '2026-06-18', 85),
  (DATE '2026-07-02', 150)
) AS sales(sold_at, amount)
GROUP BY 1 ORDER BY 1;
```

## Engine catalog examples

Source examples may require additional data or extensions. Expressions are wrapped in SELECT; execution verification is not recorded.

Reported for: overload-364e1499a3b31b6d, overload-f631ee5353c08dd7, overload-707c3ce29eb71f2a, overload-e815fe648ba59f1f, overload-696623bb8b4b05c9, overload-b0cae1c0988f2b33, overload-d79f5dbb9d7776cf

```sql
SELECT sum(A);
```

## Runnable examples

Executed successfully in Haybarn WASM 1.5.5-rc3. Sample data and guide examples are separate from the original catalog.

```sql
SELECT sum(A)
FROM (VALUES
  (10),
  (20),
  (NULL)
) AS sample("A");
```

## In other engines

### BigQuery: sum()



BigQuery:

```sql
SELECT SUM(x IGNORE NULLS) AS x
```

Haybarn / DuckDB:

```sql
SELECT SUM(x) AS x
```

### Snowflake

Uses sum as part of a larger rewrite.

Snowflake:

```sql
SELECT * FROM produce PIVOT(SUM(produce.sales) FOR produce.quarter IN ('Q1', 'Q2'))
```

Haybarn / DuckDB:

```sql
SELECT * FROM produce PIVOT(SUM(sales) FOR quarter IN ('Q1' AS "'Q1'", 'Q2' AS "'Q2'"))
```
