# DuckDB [wvlet](https://wvlet.org/) Community Extension
[Wvlet](https://wvlet.org/) a cross-SQL flow-style query language for functional data modeling and interactive data analysis.
This extension adds support for executing **wvlet** scripts directly through DuckDB SQL.
### Examples
```sql
D SELECT * FROM wvlet('select 1');
-- wvlet version=0.0.0+1-e9ceb08b+20241124-0132, src=01JDF4E4BK6RA89RB7RTN4V0NV.wv:1
select 1
┌───────┐
│ 1 │
│ int32 │
├───────┤
│ 1 │
└───────┘
D SELECT * FROM wvlet('select version()');
-- wvlet version=0.0.0+1-e9ceb08b+20241124-0132, src=01JDF4E6NJ94JG6D5K95REX3S2.wv:1
select version()
┌─────────────┐
│ "version"() │
│ varchar │
├─────────────┤
│ v1.1.3 │
└─────────────┘
D CREATE TABLE t1 AS SELECT 42 AS i, 84 AS j;
D SELECT * FROM wvlet('from t1');
-- wvlet version=0.0.0+1-e9ceb08b+20241124-0132, src=01JDF4ECWR417HJQNG1GSHCGH0.wv:1
select * from t1
┌───────┬───────┐
│ i │ j │
│ int32 │ int32 │
├───────┼───────┤
│ 42 │ 84 │
└───────┴───────┘
```
### Status
- Experimental + Unstable
