Since temporal data is separated into two tables, to get all temporal data you need to combine data from both tables, but there is no sub-clause defined in the SQL:2011 standard for that purpose. However, the SQL Server team has introduced the extension (sub-clause) ALL to simplify such queries.
Here is a temporal query that returns both actual and historical data for the person with the ID of 7:
SELECT PersonID, FullName, OtherLanguages, ValidFrom, ValidTo FROM Application.People FOR SYSTEM_TIME ALL WHERE PersonID = 7;
The query returns 14 rows, since there are 13 historical rows and one entry in the actual table. Here is the logically equivalent, standard, but a bit more complex query:
SELECT PersonID, FullName, ...
