How to combine stored procedure and select query result?
===

I am trying to combine the results of xp_cmdshell with a select query.
I have tried union & read about creating a temp table, but as my result will be having only 1 column. To be more precise i need a smaller query to combine the results of xp_cmdshell with select query as am trying to use it in union based sql injection 

For example:
Select name from employee
union
exec xp_cmdshell 'whoami'

I know this wont work but somewhat similar would be great :)
