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.
```js
const { data, error } = await supabase
.rpc('hello_world')
}
```
```py
# Not yet implemented
```
## Parameters
fn
required
string
The function name to call.
params
optional
undefined | object
The parameters to pass to the function call.
## Examples
### Call a stored procedure
This is an example invoking a stored procedure.
```js
const { data, error } = await supabase
.rpc('hello_world')
}
```
```py
# Not yet implemented
```
### With Parameters
```js
const { data, error } = await supabase
.rpc('echo_city', { name: 'The Shire' })
}
```
```py
# Not yet implemented
```
### Bulk call
```js
const { data, error } = await supabase
.rpc('echo_city', [
{ name: 'The Shire' },
{ name: 'Mordor' }
])
}
```
```py
# Not yet implemented
```
### With filters.
Stored procedures that return tables can also be combined with
[Modifiers](/docs/client/using-modifiers) and
[Filters](/docs/client/using-filters).
```js
const { data, error } = await supabase
.rpc('echo_all_cities')
.eq('name', 'The Shire')
```
```py
# Not yet implemented
```
