The Wiert Corner - irregular stream of stuff: jpluimers

This is way cool, and has been there for a long time, and I completely missed it until recently (:

On the Stack Exchange Data Explorer, you can write your own queries for any of the StackExchange sites as they share a common database infrastructure.

The queries can even contain an execution plan, and given the large number of questions (the total of Questions (table Posts) is total over 10 million now: select count(*) as QuestionCount from Posts as Questions).

There are many examples, for instance this one by sam.saffron and  TLama that lists posts outside the Delphi area:

DECLARE @MyUserID INT = ##UserID:int##

SELECT
    Answer.Id AS [Post Link],
    Answer.Score AS [Score],
    Question.Tags,
    Answer.CreationDate AS [Creation Date]
FROM
    Posts Question
LEFT JOIN Posts Answer ON Question.ID = Answer.ParentId
WHERE
    Answer.PostTypeId = 2 AND
    Answer.OwnerUserId = @MyUserID AND
    Question.Tags NOT LIKE '%<delphi>%'
ORDER BY
    Question.CreationDate
ASC
