When using union all, how can I order result set of how it gets displayed? For example

Right now it returned

Descripton SalesType Customercode Jan      Feb       Mar       Apr      May      Jun      Jul      Aug      Oct      Nov      Dec      Total
Sale        Direct        1        $ $ $
Manager        Resell        1        $ $ $
Inter        Extr        1        $ $ $
Exter        EU        1        $ $ $

I want to return like or any order of result set

To pull off a customized ordering you'll need to include an ORDER BY with a CASE block, like this..
<total air code, look at the last line>

select * from (
   select * from #temp_table1
   union all 
   select * from #temp_table2
   union all 
   select * from #temp_table3
   union all 
   select * from #temp_table4) a
group by Descripton,SalesType,Customercode,Jan,Feb ,Mar Apr,May,Jun,Jul,Aug,Oct,Nov,Dec,Total
ORDER BY CASE Descripton 
   WHEN 'Inter' THEN 1 
   WHEN 'Exter' THEN 2 
   WHEN 'Manager' THEN 3 
   WHEN 'Sale' THEN 4 
   ELSE 5 END

Open in new window
