### Update jsonb columns
If you want to update a jsonb column, you have to use "sql.json()"
```js
const user = {
id: 1,
location: {
city: "Toronto",
street: "1st michel avenue",
country: "Canada"
}
name: 'Murray',
}

sql`
update users set location = ${
sql.json(user.location)
}
where user_id = ${ user.id }
`

// Which results in:
update users set "location" = $1 where user_id = $2
```
