## Notes
|
|
|
|
- `update()` should always be combined with [Filters](/docs/reference/javascript/using-filters) to target the item(s) you wish to update.
|
|
|
|
## Examples
|
|
|
|
### Updating your data
|
|
|
|
```js
|
|
const { data, error } = await supabase
|
|
.from('cities')
|
|
.update({ name: 'Middle Earth' })
|
|
.match({ name: 'Auckland' })
|
|
```
|
|
|
|
### Updating JSON data
|
|
|
|
Postgres offers a
|
|
[number of operators](https://www.postgresql.org/docs/current/functions-json.html)
|
|
for working with JSON data. Right now it is only possible to update an entire JSON document,
|
|
but we are [working on ideas](https://github.com/PostgREST/postgrest/issues/465) for updating individual keys. For example:
|
|
|
|
```js
|
|
const { data, error } = await supabase
|
|
.from('users')
|
|
.update(
|
|
`
|
|
address: {
|
|
street: 'Melrose Place',
|
|
postcode: 90210
|
|
}
|
|
`
|
|
)
|
|
.eq('address->postcode', 90210)
|
|
```
