I put this where statment in and it fixed the problem. The emp_id_nr in
tblemployee was null for empnr starting with six zeros.

FROM tblemployee where emp_nr not like
'000000%'))

I doubt that rewriting as a join is going to solve anything. That would
be a bug of a size that would be known, and it is not unlikely your
database does that internally anyway. Maybe better to start looking if
SYS_EMP_ID_NR and emp_id_nr don't have any NULL's, have the same
datatype, are padded the same way or something.

Rewriting that requires an OUTER JOIN, which might be less than
efficient. But if you want to try:
SELECT job.*
FROM temptblJOBEVL job LEFT JOIN tblemployee emp
ON job.SYS_EMP_ID_NR = emp.emp_id_nr
WHERE emp.emp_id_nr IS NULL
I prefer the NOT EXISTS syntax, I think it is easier to read:
SELECT job.*
FROM temptblJOBEVL job
WHERE NOT EXISTS (
SELECT 1
FROM tblemployee emp
WHERE job.SYS_EMP_ID_NR = emp.emp_id_nr
)
All should return the same results, but have fun :)
