suppose the records in a table containing the records below :
inventbatchid itemid a2 a3 a4 PIC3
PO10901 AB0001 A DX 20 c:\photo\abc135.jpg
PO10901 AB0001 A DX 20 c:\photo\abc13512321321.jp
PO10901 AB0001 A DX 20 c:\photo\ac135.jpg
In this case, which record will be returned by "MAX" function ? Tks
select inventbatchid,itemid,a2,a3
Tent,
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'
into #tmp3 from #tmp2
