query on procedure

Hi,
Please see the below procedure.
create procedure a1
as
begin
create table #table1
{
empid int;
empname varchar
}
insert into #table1 select empid,empname from employee where
empcode='50'
select e.* from employee e, #table1 as t1 where e.empid=t1.empid and
e.empname=t1.empname; /* query1 */
end
In location query1,empid , empname in #table1 substitutes all the
values at the time, i need to substitute each value individually in
location query1.
Is there any way to do this?

I trust your production code will have meaningful procedure names.

Should be
empid int,
empname varchar(30) -- or whatever

Why are you doing this, instead of simply
select * -- you should really have an explicit list of fields
from employee
where empcode = '50'
Does the 'employee' table really have both empcode and empid? If
so, then are they both enforced as unique?

I don't understand what you mean. Please provide an example of what
it does now, and of what you want it to do instead.
