I thought by now I'd know all features of the Stack Exchange Data Explorer but apparently I don't. This is what I do:
- Click the Compose Query button on the home page.
SELECT MAX(CreationDate) FROM Postsinto the editor and click Run Query
- Click the 'permalink' option. This will take you to a read-only version of the query, which is no surprise, but SEDE also automagically added some documentation to my query:
This is the added text:
-- Approximate date of last Data Explorer update -- based on the most recent post available to Data Explorer -- -- adapted from this query: -- http://data.stackexchange.com/superuser/s/1002/top-100-most-frequent-voters
Sadly, the linked query isn't really relevant. I can reproduce it in a private window, so it's not something tied to my account.
