SQL Server compare results of two queries that should be identical

Question

I am modifying a sql server 2005 stored procedure slightly for performance, and I would like to quickly make sure the old stored proc and the new one return the exact same r

Answer 1

create table #OldProcResults (
    
)

create table #NewProcResults (
    
)

insert into #OldProcResults
    exec MyOldProc

insert into #NewProcResults
    exec MyNewProc

then use Jabs' answer to compare the two tables.
