-- Copy of the Top Close Voters query, with PostHistoryTypeId = 11 for Reopen
-- http://data.stackexchange.com/programmers/query/90851/top-close-voters

-- Returns all close voters ordered from most to least votes
-- Only counts closed votes that actually resulted in an open,
-- and does not count deleted questions

-- I wouldn't recommend running this on StackOverflow due to its size

declare @userid int
declare @users table
(
  userid int,
  ReopenCount int
)

-- Cursor for all users who can vote to close
declare cur cursor for 
    select id 
    from users
    where reputation >= 500
    
open cur
fetch next from cur into @userid
while @@fetch_status = 0
begin

  insert into @users(userid, ReopenCount)
  SELECT @userid, count(*)
  FROM PostHistory 
  WHERE PostHistoryTypeId = 11 
  AND Text LIKE '%' + CAST(@userid AS nvarchar) + '%'
  
  fetch next from cur into @userid
end

close cur
deallocate cur
