 ### Level
 
-This column stores the event level (Error, Information, etc.). For backwards-compatibility reasons it defaults to a length of 128 characters, but 12 characters is recommended. Alternately, the `StoreAsEnum` property can be set to `true` which causes the underlying level enum integer value to be stored as a SQL `tinyint` column. The `DataType` property can only be set to `nvarchar` or `tinyint`. Setting the `DataType` to `tinyint` is identical to setting `StoreAsEnum` to `true`.
