Parallel SQL Query Execution..?

Question

Hi frnds,

 

Create Table #City(CityName varchar(40))

insert into #City

select top 5 City from State where Name='TamilNadu' order by City

insert into #City

select top 5 City from State where Name='Kerala' order by City

Select Top 5 * from #City order by City

 

Frnds this is sample Query ,

 

in my SQL Server database around 5laks records is there , when i get all data from table and  fetch top 5 records means it will take long time to execute

how can i execute these 2 queries in same time .
