Since BIT
column is 1
or 0
, you can't apply MAX()
to it. The only option I saw in other forums is to cast it as tinyint
. Like so. See if this works.
select rc.[race number],
max(case when seqnum = 1 then [candidate num] end) as Winner,
max(case when seqnum = 1 then Votes end) as WinningVotes,
max(case when seqnum = 1 then party end) as WinningParty,
max(case when seqnum = 1 then leader end) as Winner1,
max(case when seqnum = 1 then CAST(winner AS tinyint) end) as WinnerSelected,
max(case when seqnum = 1 then [leader percent] end) as WinnerPercent,
max(case when seqnum = 2 then [candidate num] end) as Loser,
max(case when seqnum = 2 then Votes end) as LosingVotes,
max(case when seqnum = 2 then party end) as LosingParty,
max(case when seqnum = 2 then leader2 end) as Loser2,
max(case when seqnum = 2 then [leader2 percent] end) as LoserPercent,
max(case when seqnum = 2 then CAST(winner AS tinyint) end) as LoserSelected
from

select rc.[race number],
rc.[candidate num],

row_number() over (partition by rc.[race number] order by votes desc) as seqnum

inner join dbo.[RACE] r
