# Notification.EventType

| **Type** | **Read/write** | **Author** | **Availability** |
| --- | --- | --- | --- |
| [Data provider](/v1/docs/what-are-a-data-provider-and-a-direct-provider) | Read | FINBOURNE | Provided with LUSID |

Providing you have sufficient [access control permissions](/v1/docs/creating-policies-to-control-access-to-providers-for-different-luminesce-end-users), the `Notification.EventType` provider enables you to write a [Luminesce SQL query](/v1/docs/understanding-the-luminesce-sql-query-syntax) that retrieves the [event types](/v1/docs/what-system-events-can-i-subscribe-to) and their schemas that you can subscribe to with LUSID's Notification Service.

**See also**: [Notification.Subscription](/v1/docs/notificationsubscription)

## Basic usage

```sql
select * from Notification.EventType where <filter-expression>
```

## Data fields

By default, `Notification.EventType` returns a table of data populated with particular fields (columns). You can return a subset of these fields.

To list fields available to return, their data types, whether fields are considered 'main', and an explanation for each, run the following query using a [suitable tool](/v1/docs/what-tools-are-available-to-write-luminesce-queries):

```sql
select FieldName, DataType, IsMain, IsPrimaryKey, SampleValues, Description from Sys.Field where TableName = 'Notification.EventType' and FieldType = 'Column';
```

> **Note:** Fields marked 'main' are returned by queries that select a caret character, for example `select ^ from Notification.EventType`.

## Examples
