MAX function

Presumably you'd want each max based on a specific inventbatchid, something like this:


select t2.inventbatchid,t2.itemid,t2.a2,t2.a3,t2.a4,t2.Tent,
    t2_pics.PIC3,t2_pics.PIC2,t2_pics.PIC1
into #tmp3
from #tmp2 t2
inner join (
    select inventbatchid,
        max(case typeid when 'ImgS' then pic else '' end) as 'PIC3',
        max(case typeid when 'sketchA' then pic else '' end) as 'PIC2',
        max(case typeid when 'sketchB' then pic else '' end) as 'PIC1'
    from #tmp2
    group by inventbatchid
) AS t2_pics on
    t2_pics.inventbatchid = t2.inventbatchid
