Use SQL for generation

What about a using SQLite for test data generation?
## Example:
```sql
CREATE TABLE test (
id INTEGER PRIMARY KEY NOT NULL,
x REAL NOT NULL,
y REAL NOT NULL,
z REAL NOT NULL
);
INSERT INTO test
WITH RECURSIVE
cnt( id, x, y, z) AS (
VALUES(1 , random(), random(), random()) UNION ALL
SELECT id+1,random(),random(), random() FROM cnt WHERE ID<1000)
select * from cnt;
```
