Appending results returned by multiple queries into 1 row?

Question

I have multiple select queries in a procedure. Each query processes different tables and returns one or two columns that need to be inserted to a staging table.
The results of these queries should be appended to one row.
select col1, col2 from table1 where......
select col3, col4 from table2 where....
Now the results of the above queries col1,col2, col3, col4 should be inserted to a temp table into one row as 4 columns.
How would I achieve this?

Thanks very much for everyone's help.
I am little confused. How would this fit in my queries. Please help me figure out how should I put these queries together.
SELECT
o.outageid,
et.Billlabor
FROM
emp_time et,
job j,
rate r,
vend v,
outage o,
outage_emp oe
where
j.jobid = et.jobid
and et.rateid = r.rateid
and r.vendid = v.vendid
and et.outage_empid = oe.outage_empid
and oe.outageid = o.outageid
group by
j.outageid
select
o.outageid,
count(e.empid) as empcount,
decode(o.outage_hrs, 0, 1, 0),
from
employee e,
outage_emp oe,
outage o,
outage_vend v
WHERE
e.empid = oe.outage_empid
and oe.outageid = o.outageid
and o.outageid = v.outageid
group by
