Using the exception join worked, but I have to still do the following:

select sum(error_count) as total_errors from (
select count(*) as error_count
from mprlib.v_tshoursumm a exception join mprlib.v_reqhoursumm b
on a.em_number = b.em_number and a.timesheet_code = b.timesheet_code
and a.hours_summary = b.hours_summary
where a.em_number = :id OR b.em_number = :id
union
select count(*) as error_count
from mprlib.v_reqhoursumm a exception join mprlib.v_tshoursumm b
on a.em_number = b.em_number and a.timesheet_code = b.timesheet_code
and a.hours_summary = b.hours_summary
where a.em_number = :id OR b.em_number = :id)table;

Unless I am missing something. This was the other way I could make
sure I wasn't missing anything. I am planning on putting this into a
stored procedure now. Any other optimizations you can recommend? I
will be asking the iSeries what it thinks yet.

Exception join instead of the union as Scott recommended:

Subject: Re: Comparing data in two tables

This seems to work and could even be used outright in a stored
procedure. Thoughts?

select count(*) from (
select timesheet_code, count(timesheet_code) as count from (
select em_number, prhrt as timesheet_code, prhrsq as hours_summary
from mprlib.v_tshoursumm
union all
select em_number, timesheet_code, hours_summary from mprlib.v_reqhoursumm
order by em_number, timesheet_code ) table
where em_number = :id
group by timesheet_code
having count(timesheet_code) <> 2) table;

Is there a better way to do this?
