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 > **Note:** For more example Luminesce SQL queries, visit our [Github repo](https://github.com/finbourne/luminesce-examples/tree/master/examples). ### Example 1: Retrieve all event types ```sql select * from Notification.EventType group by Id; ``` ### Example 2: Retrieve first ten event types and their schemas ```sql select * from Notification.EventType limit 10; ``` ### Example 3: Retrieve the schema for a particular event type ```sql select * from Notification.EventType where Id = 'PortfolioCreated'; ```
