Hi Willem,

Could you provide more details? Do you get a specific error message?

You should not expect the same row count in both source table and
result set. Even in your example -- you provided 8 source rows, and
4 result rows. You can determine the correct number of results via
"the number of records, related to client_ids having two or more records
in all_client_times, minus one". It may be true that you have 750k
records but only 658 rows that satisfy this requirement.
What do you get for this query?
select count(*) from ( select client_id, count(*) as rows
from all_client_times group by client_id having count(*) > 1 ) as x
