You can call stored procedures as a "Remote Procedure Call".

That's a fancy way of saying that you can put some logic into your database then call it from anywhere.
It's especially useful when the logic rarely changes - like password resets and updates.


<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
final res = await supabase
  .rpc('hello_world')
  .execute();
```


</TabsPanel>

<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
final res = await supabase
  .rpc('echo_city', params: { 'name': 'The Shire' })

### With count option

You can specify a count option to get the row count along with your data.
Allowed values for count option are `exact`, `planned` and `estimated`.


<Tabs
  defaultActiveId="dart"
  groupId="reference/dart"
  values={[{ label: 'Dart', value: 'dart' }]}>

<TabsPanel id="dart" label="dart">

```dart
final res = await supabase
  .rpc('hello_world')
  .execute(count: CountOption.exact);
```
