COALESCE - Selecting each record with all not nul values

I had three rows of data that had the same acount number but differnt variation in the three columns. I had to select each account with not null column . This was achieved by the following...

My data
create table #tmpcol(c219 int, c220 int,c221 int)
INSERT INTO #tmpcol
SELECT null,220,null
INSERT INTO #tmpcol
SELECT 219,null,null
INSERT INTO #tmpcol
SELECT null,null,221


select top 1 * from #tmpcolorderby coalesce(100*c219,10*c220,c221) desc
