[sql] allow using prepared statement more than once

Currently, I can use a query with params only once with sqlite:

```
await db.execute(
"INSERT INTO team (id, name, created_at) VALUES ($1, $2, $3);",
[team.id, team.name, team.created_at]
);
```

But, if I want to insert a lot of data, I have to make a loop where I re-prepare and execute the statement.
In terms of performance, it could be great if we could use one prepared statement, then loop over it!

```
const stmt = await db.prepare("INSERT INTO team (id, name, created_at) VALUES ($1, $2, $3);");

// Then loop over elements:
await stmt.execute([x._id, x.name, x.person, x.dueAt, x.completedAt, x.createdAt]);
```
