Question

I want to use order by clause in inner select queries with union operator i.e.

select colname from table where <cond1> order by colname 
union
select colname from table where <cond2> order by colname 

I can use order by with the complete result but I want to have the results from first query ordered by and then the result of second query ordered by.

Please give me some suggestions upon it.

Answer 1

Following should do… i guess

select colname,1 as OrderCol from table where <cond1> 
union select colname,2 as OrderCol  from table 
where <cond2>  
order by OrderCol
