Question

Here total two union binding three queries, first query retrieving records from a virtual table(Inner query) and two simple queries retrieving records from a physical tables.
All three queries making a virtual table named “vertulatable” retrieving all records from “vertualtable” with group by and order by clause.
But the problem is its not doing a proper descending order by final price. Some records retrieved from mediater query has value 150 but showing after 0 or less then 150,but should be top from 0 or less then 150 in resultant records.

SELECT 
sum(vertualtable.WyoPrice) as WyoPrice, 
       sum(vertualtable.normalPrice) as normalPrice, 
       vertualtable.sbnam,
       vertualtable.sbwynum, 
      if(vertualtable.sbwynum in(25,43), 
           sum(vertualtable.WyoPrice), sum(vertualtable.normalPrice)) as finalPricePrev,
        sum(vertualtable.finalPrice) as  finalPrice,
     vertualtable.BuilderStatus

 order by vertualtable.finalPrice desc 

Thanks a lot.

I made some small modifications to your query – try to see if the result is the one you expected
