Laurence Isla 08e9cdde5e docs: data api docs functions (#44412)
## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

Replaces "stored procedures" with "functions" for everything related to
the Data API.

## Additional context

It's not accurate to call database functions "stored procedures". It may
have been that way before Postgres 11, but now it causes confusion
because PostgREST allows functions and not stored procedures.

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **Documentation**
* Standardized terminology across docs, SDK guides, CLI/config specs,
examples, UI, and config comments to use "database functions" instead of
"stored procedures".
* Updated API docs, CLI/config descriptions, Studio UI labels, help
text, empty-state and navigation copy, RPC documentation, and example
text for consistency.
* Adjusted explanatory text and error/help messages to reflect the
revised terminology.

title: Initializing
description: |
Initializing a new client is pretty straightforward. Find your project url and public key from the
admin panel and pass it into your client initialization function.
`Supabase` is heavily dependent on Models deriving from `BaseModel`. To interact with the API, one must have the associated model (see example) specified.
Leverage `Table`, `PrimaryKey`, and `Column` attributes to specify names of classes/properties that are different from their C# Versions.
examples:
- id: csharp-init-standard
name: Standard
code: |
```c#
var url = Environment.GetEnvironmentVariable("SUPABASE_URL");
var key = Environment.GetEnvironmentVariable("SUPABASE_KEY");
var options = new Supabase.SupabaseOptions
{
AutoConnectRealtime = true
};
var supabase = new Supabase.Client(url, key, options);
await supabase.InitializeAsync();
```
- id: csharp-init-maui
name: Dependency Injection (Maui-like)
code: |
```c#
public static MauiApp CreateMauiApp()
{
// ...
var builder = MauiApp.CreateBuilder();
var url = Environment.GetEnvironmentVariable("SUPABASE_URL");
var key = Environment.GetEnvironmentVariable("SUPABASE_KEY");
var options = new SupabaseOptions
{
AutoRefreshToken = true,
AutoConnectRealtime = true,
// SessionHandler = new SupabaseSessionHandler() <-- This must be implemented by the developer
};
// Note the creation as a singleton.
builder.Services.AddSingleton(provider => new Supabase.Client(url, key, options));
}
```
- id: csharp-init-showing-models
name: With Models Example
code: |
```c#
// Given the following Model representing the Supabase Database (Message.cs)
[Table("messages")]
public class Message : BaseModel
{
[PrimaryKey("id")]
public int Id { get; set; }
[Column("username")]
public string UserName { get; set; }
[Column("channel_id")]
public int ChannelId { get; set; }
public override bool Equals(object obj)
{
return obj is Message message &&
Id == message.Id;
}
public override int GetHashCode()
{
return HashCode.Combine(Id);
}
}
void Initialize()
{
// Get All Messages
var response = await client.Table<Message>().Get();
List<Message> models = response.Models;
// Insert
var newMessage = new Message { UserName = "acupofjose", ChannelId = 1 };
await client.Table<Message>().Insert();
// Update
var model = response.Models.First();
model.UserName = "elrhomariyounes";
await model.Update();
// Delete
await response.Models.Last().Delete();
// etc.
}
```
- id: sign-up
title: 'SignUp()'
description: |
Creates a new user.
notes: |
- By default, the user needs to verify their email address before logging in. To turn this off, disable **Confirm email** in [your project](https://supabase.com/dashboard/project/_/auth/providers).
- **Confirm email** determines if users need to confirm their email address after signing up.
- If **Confirm email** is enabled, a `user` is returned but `session` is null.
- If **Confirm email** is disabled, both a `user` and a `session` are returned.
- When the user confirms their email address, they are redirected to the [`SITE_URL`](https://supabase.com/docs/guides/auth/redirect-urls) by default. You can modify your `SITE_URL` or add additional redirect URLs in [your project](https://supabase.com/dashboard/project/_/auth/url-configuration).
- If SignUp() is called for an existing confirmed user:
- When both **Confirm email** and **Confirm phone** (even when phone provider is disabled) are enabled in [your project](/dashboard/project/_/auth/providers), an obfuscated/fake user object is returned.
- When either **Confirm email** or **Confirm phone** (even when phone provider is disabled) is disabled, the error message, `User already registered` is returned.
examples:
- id: sign-up
name: Sign up.
isSpotlight: true
code: |
```c#
var session = await supabase.Auth.SignUp(email, password);
```
- id: sign-in-with-password
title: 'SignIn(email, password)'
description: |
Log in an existing user using email or phone number with password.
notes: |
- Requires either an email and password or a phone number and password.
examples:
- id: sign-in-with-email-and-password
name: Sign in with email and password
isSpotlight: true
code: |
```c#
var session = await supabase.Auth.SignIn(email, password);
```
- id: sign-in-with-phone-and-password
name: Sign in with phone and password
code: |
```c#
var session = await supabase.Auth.SignIn(SignInType.Phone, phoneNumber, password);
```
- id: sign-in-with-otp
title: 'SendMagicLink() and SignIn(SignInType, Phone)'
notes: |
- Requires either an email or phone number.
- This method is used for passwordless sign-ins where a OTP is sent to the user's email or phone number.
- If you're using an email, you can configure whether you want the user to receive a magiclink or a OTP.
- If you're using phone, you can configure whether you want the user to receive a OTP.
- The magic link's destination URL is determined by the [`SITE_URL`](https://supabase.com/docs/guides/auth/redirect-urls). You can modify the `SITE_URL` or add additional redirect urls in [your project](https://supabase.com/dashboard/project/_/auth/settings).
examples:
- id: sign-in-with-email
name: Send Magic Link.
isSpotlight: true
description: |
The user will be sent an email which contains either a magiclink or a OTP or both. By default, a given user can only request a OTP once every 60 seconds.
You can pass `emailRedirectTo` with dynamic link to bring the users back to your app after they click on the magic link.
code: |
```c#
var options = new SignInOptions { RedirectTo = "http://myredirect.example" };
var didSendMagicLink = await supabase.Auth.SendMagicLink("joseph@supabase.io", options);
```
- id: sign-in-with-sms-otp
name: Sign in with SMS OTP.
description: The user will be sent a SMS which contains a OTP. By default, a given user can only request a OTP once every 60 seconds.
code: |
```c#
await supabase.Auth.SignIn(SignInType.Phone, "+13334445555");
// Paired with `VerifyOTP` to get a session
var session = await supabase.Auth.VerifyOTP("+13334445555", TOKEN, MobileOtpType.SMS);
```
- id: sign-in-with-oauth
title: 'SignIn(Provider)'
description: |
Signs the user in using third party OAuth providers.
notes: |
- This method is used for signing in using a third-party provider.
- Supabase supports many different [third-party providers](https://supabase.com/docs/guides/auth#providers).
examples:
- id: sign-in-using-a-third-party-provider
name: Sign in using a third-party provider
isSpotlight: true
code: |
```c#
var signInUrl = supabase.Auth.SignIn(Provider.Github);
```
- id: sign-in-with-scopes
name: With scopes
description: |
If you need additional data from an OAuth provider, you can include a space-separated list of scopes in your request to get back an OAuth provider token.
You may also need to specify the scopes in the provider's OAuth app settings, depending on the provider.
code: |
```c#
var signInUrl = supabase.Auth.SignIn(Provider.Github, 'repo gist notifications');
// after user comes back from signin flow
var session = supabase.Auth.GetSessionFromUrl(REDIRECTED_URI);
```
- id: sign-out
title: 'SignOut()'
description: |
Signs out the current user, if there is a logged in user.
notes: |
- In order to use the `SignOut()` method, the user needs to be signed in first.
examples:
- id: sign-out
name: Sign out
isSpotlight: true
code: |
```c#
await supabase.Auth.SignOut();
```
- id: verify-otp
title: 'VerifyOtp()'
notes: |
- The `VerifyOtp` method takes in different verification types. If a phone number is used, the type can either be `sms` or `phone_change`. If an email address is used, the type can be one of the following: `signup`, `magiclink`, `recovery`, `invite` or `email_change`.
- The verification type used should be determined based on the corresponding auth method called before `VerifyOtp` to sign up / sign-in a user.
examples:
- id: verify-sms-one-time-password(otp)
name: Verify Sms One-Time Password (OTP)
isSpotlight: true
code: |
```c#
var session = await supabase.Auth.VerifyOTP("+13334445555", TOKEN, MobileOtpType.SMS);
```
- id: get-session
title: 'CurrentSession'
description: |
Returns the session data, if there is an active session.
examples:
- id: get-the-session-data
name: Get the session data
isSpotlight: true
code: |
```c#
var session = supabase.Auth.CurrentSession;
```
- id: get-user
title: 'CurrentUser'
description: |
Returns the user data, if there is a logged in user.
examples:
- name: Get the logged in user
isSpotlight: true
code: |
```c#
var user = supabase.Auth.CurrentUser;
```
- id: update-user
title: 'UpdateUser()'
description: |
Updates user data, if there is a logged in user.
notes: |
- In order to use the `UpdateUser()` method, the user needs to be signed in first.
- By Default, email updates sends a confirmation link to both the user's current and new email.
To only send a confirmation link to the user's new email, disable **Secure email change** in your project's [email auth provider settings](https://supabase.com/dashboard/project/_/auth/settings).
examples:
- id: update-the-email-for-an-authenticated-user
name: Update the email for an authenticated user
description: Sends a "Confirm Email Change" email to the new email address.
isSpotlight: true
code: |
```c#
var attrs = new UserAttributes { Email = "new-email@example.com" };
var response = await supabase.Auth.Update(attrs);
```
- id: update-the-password-for-an-authenticated-user
name: Update the password for an authenticated user
isSpotlight: false
code: |
```c#

- id: listen-to-auth-changes
name: Listen to auth changes
isSpotlight: true
code: |
```c#
supabase.Auth.AddStateChangedListener((sender, changed) =>
{
switch (changed)
{
case AuthState.SignedIn:
break;
case AuthState.SignedOut:
break;
case AuthState.UserUpdated:
break;
case AuthState.PasswordRecovery:
break;
case AuthState.TokenRefreshed:
break;
}
});
```
- id: auth-reset-password-for-email
title: 'ResetPasswordForEmail()'
description: |
Sends a reset request to an email address.
notes: |
Sends a password reset request to an email address. When the user clicks the reset link in the email they are redirected back to your application. Prompt the user for a new password and call Auth.UpdateUser():
examples:
- id: reset-password
name: Reset password for Flutter
isSpotlight: true
code: |
```c#
await supabase.Auth.ResetPasswordForEmail("joseph@supabase.io");
```
- id: invoke
title: 'invoke()'
description: |
Invokes a Supabase Function. See the [guide](/docs/guides/functions) for details on writing Functions.
notes: |
- Requires an Authorization header.
- Invoke params generally match the [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) spec.
examples:
- id: basic-invocation
name: Basic invocation.
isSpotlight: true
code: |
```c#
var options = new InvokeFunctionOptions
{
Headers = new Dictionary<string, string> {{ "Authorization", "Bearer 1234" }},
Body = new Dictionary<string, object> { { "foo", "bar" } }
};
await supabase.Functions.Invoke("hello", options: options);
```
- id: modeled-invocation
name: Modeled invocation
code: |
``` c#
class HelloResponse
{
[JsonProperty("name")]
public string Name { get; set; }
}
await supabase.Functions.Invoke<HelloResponse>("hello");
```
- id: select
description: |
Performs vertical filtering with SELECT.
title: 'Fetch data: Select()'
notes: |
- **LINQ expressions do not currently support parsing embedded resource columns. For these cases, `string` will need to be used.**
- **When using string Column Names to select, they must match names in database, not names specified on model properties.**
- Additional information on modeling + querying Joins and Inner Joins can be found [in the `postgrest-csharp README`](https://github.com/supabase-community/postgrest-csharp/blob/master/README.md#foreign-keys-join-tables-and-relationships)
- By default, Supabase projects will return a maximum of 1,000 rows. This setting can be changed in Project API Settings. It's recommended that you keep it low to limit the payload size of accidental or malicious requests. You can use `range()` queries to paginate through your data.
- `From()` can be combined with [Modifiers](/docs/reference/csharp/using-modifiers)
- `From()` can be combined with [Filters](/docs/reference/csharp/using-filters)
- If using the Supabase hosted platform `apikey` is technically a reserved keyword, since the API gateway will pluck it out for authentication. [It should be avoided as a column name](https://github.com/supabase/supabase/issues/5465).
examples:
- id: getting-your-data
name: Getting your data
isSpotlight: true
code: |
```c#
// Given the following Model (City.cs)
[Table("cities")]
class City : BaseModel
{
[PrimaryKey("id")]
public int Id { get; set; }
[Column("name")]
public string Name { get; set; }
[Column("country_id")]
public int CountryId { get; set; }

class Movie : BaseModel
{
[PrimaryKey("id")]
public int Id { get; set; }
[Column("name")]
public string Name { get; set; }
[Column("created_at")]
public DateTime CreatedAt { get; set; }
//... etc.

var result = await supabase
.From<Movie>()
.Select(x => new object[] {x.Name, x.CreatedAt})
.Get();
```
- id: query-foreign-tables
name: Query foreign tables
description: If your database has relationships, you can query related tables too.
code: |
```c#
var data = await supabase
.From<Transactions>()
.Select("id, supplier:supplier_id(name), purchaser:purchaser_id(name)")
.Get();
```
- id: filtering-with-inner-joins
name: Filtering with inner joins
description: |
If you want to filter a table based on a child table's values you can use the `!inner()` function. For example, if you wanted
to select all rows in a `message` table which belong to a user with the `username` "Jane":
code: |
```c#
var result = await supabase
.From<Movie>()
.Select("*, users!inner(*)")
.Filter("user.username", Operator.Equals, "Jane")
.Get();
```
- id: querying-with-count-option
name: Querying with count option
description: |
You can get the number of rows by using the count option.
Allowed values for count option are [exact](https://postgrest.org/en/stable/api.html#exact-count), [planned](https://postgrest.org/en/stable/api.html#planned-count) and [estimated](https://postgrest.org/en/stable/api.html#estimated-count).
code: |
```c#
var count = await supabase
.From<Movie>()
.Select(x => new object[] { x.Name })
.Count(CountType.Exact);
```
- id: querying-json-data
name: Querying JSON data
description: |
If you have data inside of a JSONB column, you can apply select
and query filters to the data values. Postgres offers a
[number of operators](https://www.postgresql.org/docs/current/functions-json.html)
for querying JSON data. Also see
[PostgREST docs](http://postgrest.org/en/v7.0.0/api.html#json-columns) for more details.
code: |
```c#
var result = await supabase
.From<Users>()
.Select("id, name, address->street")
.Filter("address->postcode", Operator.Equals, 90210)
.Get();
```

title: 'Create data: Insert()'
examples:
- id: create-a-record
name: Create a record
isSpotlight: true
code: |
```c#
[Table("cities")]
class City : BaseModel
{
[PrimaryKey("id", false)]
public int Id { get; set; }
[Column("name")]
public string Name { get; set; }
[Column("country_id")]

class City : BaseModel
{
[PrimaryKey("id", false)]
public int Id { get; set; }
[Column("name")]
public string Name { get; set; }
[Column("country_id")]
public int CountryId { get; set; }
}
var models = new List<City>
{
new City { Name = "The Shire", CountryId = 554 },
new City { Name = "Rohan", CountryId = 553 },
};
await supabase.From<City>().Insert(models);
```
- id: fetch-inserted-data
name: Fetch inserted record
code: |
```c#
var result = await supabase
.From<City>()
.Insert(models, new QueryOptions { Returning = ReturnType.Representation });
```
- id: update
description: |
Performs an UPDATE on the table.
title: 'Modify data: Update()'
notes: |
- `Update()` is typically called using a model as an argument or from a hydrated model.
examples:
- id: updating-your-data-with-filter
name: Update your data using Filter
isSpotlight: true
code: |
```c#
var update = await supabase
.From<City>()
.Where(x => x.Name == "Auckland")
.Set(x => x.Name, "Middle Earth")
.Update();
```
- id: updating-your-data
name: Update your data
code: |
```c#
var model = await supabase
.From<City>()
.Where(x => x.Name == "Auckland")
.Single();
model.Name = "Middle Earth";
await model.Update<City>();
```
- id: upsert
description: |
Performs an UPSERT into the table.
title: 'Upsert data: Upsert()'
notes: |
- Primary keys should be included in the data payload in order for an update to work correctly.
- Primary keys must be natural, not surrogate. There are however, [workarounds](https://github.com/PostgREST/postgrest/issues/1118) for surrogate primary keys.
examples:
- id: upsert-your-data
name: Upsert your data
isSpotlight: true
code: |
```c#
var model = new City
{
Id = 554,
Name = "Middle Earth"
};
await supabase.From<City>().Upsert(model);
```
- id: upserting-into-tables-with-constraints
name: Upserting into tables with constraints
description: |
Running the following will cause supabase to upsert data into the `users` table.
If the username 'supabot' already exists, the `onConflict` argument tells supabase to overwrite that row
based on the column passed into `onConflict`.
isSpotlight: true
code: |
```c#
var model = new City
{
Id = 554,
Name = "Middle Earth"
};
await supabase
.From<City>()
.OnConflict(x => x.Name)
.Upsert(model);
```
- id: return-the-exact-number-of-rows
name: Return the exact number of rows
description: |
Allowed values for count option are `exact`, `planned` and `estimated`.
code: |
```c#
var model = new City
{
Id = 554,
Name = "Middle Earth"
};
await supabase
.From<City>()
.Upsert(model, new QueryOptions { Count = QueryOptions.CountType.Exact });
```
- id: delete
description: |
Performs a DELETE on the table.
title: 'Delete data: Delete()'
notes: |
- `Delete()` should always be combined with [Filters](/docs/reference/csharp/using-filters) to target the item(s) you wish to delete.
examples:
- id: delete-records
name: Delete records
isSpotlight: true
code: |
```c#
await supabase
.From<City>()
.Where(x => x.Id == 342)
.Delete();
```
- id: rpc
title: 'Database Functions: Rpc()'
description: |
You can call functions 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.
examples:
- id: call-a-database-function
name: Call a database function
isSpotlight: true
description: This is an example invoking a database function.
code: |
```c#
await supabase.Rpc("hello_world", null);
```
- id: with-parameters
name: With Parameters
code: |
```c#
await supabase.Rpc("hello_world", new Dictionary<string, object> { { "foo", "bar"} });
```
- id: subscribe
title: 'Realtime.Channel'
description: |
Subscribe to realtime changes in your database.
notes: |
- Realtime is disabled by default for new Projects for better database performance and security. You can turn it on by [managing replication](/docs/guides/api#managing-realtime).
- If you want to receive the "previous" data for updates and deletes, you will need to set `REPLICA IDENTITY` to `FULL`, like this: `ALTER TABLE your_table REPLICA IDENTITY FULL;`
examples:
- id: listen-to-broadcast
name: Listen to broadcast messages
isSpotlight: true
code: |
```c#

description: You can listen to individual rows using the format `{table}:{col}=eq.{val}` - where `{col}` is the column name, and `{val}` is the value which you want to match.
code: |
```c#
var channel = supabase.Realtime.Channel("realtime", "public", "countries", "id", "id=eq.200");
channel.AddPostgresChangeHandler(ListenType.All, (sender, change) =>
{
// The event type
Debug.WriteLine(change.Event);
// The changed record
Debug.WriteLine(change.Payload);
});
await channel.Subscribe();
```
- id: remove-channel
description: |
Unsubscribes and removes Realtime channel from Realtime client.
title: 'Unsubscribe()'
notes: |
- Removing a channel is a great way to maintain the performance of your project's Realtime service as well as your database if you're listening to Postgres changes. Supabase will automatically handle cleanup 30 seconds after a client is disconnected, but unused channels may cause degradation as more clients are simultaneously subscribed.

- id: using-modifiers
title: Using Modifiers
description: |
Filters work on the row level—they allow you to return rows that
only match certain conditions without changing the shape of the rows.
Modifiers are everything that don't fit that definition—allowing you to
change the format of the response (e.g., setting a limit or offset).

description: |
Filters allow you to only return rows that match certain conditions.

Uses PostgreSQL's `websearch_to_tsquery` function.
This function will never raise syntax errors, which makes it possible to use raw user-supplied input for search, and can be used
with advanced operators.
- `unquoted text`: text not inside quote marks will be converted to terms separated by & operators, as if processed by plainto_tsquery.
- `"quoted text"`: text inside quote marks will be converted to terms separated by `<->` operators, as if processed by phraseto_tsquery.
- `OR`: the word “or” will be converted to the | operator.
- `-`: a dash will be converted to the ! operator.

```c#
var result = await supabase.From<Quote>()
.Select(x => x.Catchphrase)
