Out of all the questions on SE, which has had the most bounties? I don't care about total amount of rep, just how many separate bounties there were.

7

I dropped the query from Nicael in my Multi-db query template and this is the result:

-- start create url from dbname
IF OBJECT_ID ( '#siteurl', 'P' ) IS NOT NULL 
    DROP PROCEDURE #siteurl;
GO
create procedure #siteurl
   @dbname nvarchar(250),
   @res nvarchar(250) OUT
   as
   begin
      -- we have three sites that have borked DNS entries
      set @dbname = (case @dbname
      when 'StackExchange.Audio' then 'StackExchange.Avp'
      when 'StackExchange.Audio.Meta' then 'StackExchange.Avp.Meta'
      when 'StackExchange.Mathoverflow.Meta' then 'net.Mathoverflow.meta'
      else @dbname
      end)
      -- and one of those doesn't want to end with .com
      if @dbname <> 'net.Mathoverflow.meta' 
         set @dbname = 'com.' + @dbname
      exec #recursesiteurl @dbname,  @res OUTPUT
   end
GO
-- create url from dbname
IF OBJECT_ID ( '#recursesiteurl', 'P' ) IS NOT NULL 
    DROP PROCEDURE #recursesiteurl;
GO
create procedure #recursesiteurl
   @dbname nvarchar(250),
   @res nvarchar(250) OUT
   as
   begin
      declare @pos integer
      declare @rec nvarchar(250)

      set @res = @dbname
      set @pos = CHARINDEX('.', @dbname)
      if (@pos > 0 ) 
      begin
         set @rec = substring(@dbname, @pos+1, len(@dbname))
         exec #recursesiteurl @rec,  @rec output
         set @res = @rec 
                  + '.' 
                  + substring(@dbname, 0, @pos) 
      end
   end;
GO

                            );

open db_c
fetch next from db_c into @db_c_name

    exec (@sql)

end;
close db_c;
deallocate db_c;

When you run this we can confirm the correctness of Nicael's answer:

  • This proves I have guessed :D – nicael Nov 6 '15 at 19:20
  • But you're the true SQL magician - I thought the data.se queries only work for one site... – nicael Nov 6 '15 at 19:23
  • @nicael it just happens to work but you either need the exec function and build up a sql string (when done wrong you get 150 errors) or a script that generates a single query with databasename.schema.table. Oh, and the timeout is still 120 seconds .... – rene Nov 6 '15 at 19:29

It's impossible to get those stats from all SE sites at once, but per this query, here on Meta the max amount of bounties is 17, and on Stack Overflow, it is 13.

I doubt any other site has larger numbers though o.0 on Tex it is 22.

On the other relatively big SE sites, the number varies from 3 to 7 with Physics topping at 11.

  • And the SO question with the most was closed as off-topic ... – DavidPostill Nov 6 '15 at 18:42
  • @David Well, ok then :) Does it matter? – nicael Nov 6 '15 at 18:45
  • Not really, it was just an observation ;) Bounties != Quality – DavidPostill Nov 6 '15 at 18:46
  • @David But the fact whether the question is closed or not doesn't always affect the question quality. At some point of time, it was on-topic, now it is not because of scope changing slightly as the time passes, did the quality of the question decrease? I don't think so. – nicael Nov 6 '15 at 18:55
  • @DavidPostill The question with 13 bounties on SO was out of desperation from the OP who had a legitimate problem which became off-topic as the site evolved. The question with 10 bounties was repeated advertising from the top answerer before a mod put a stop to it. – Mysticial Nov 6 '15 at 19:02
