select employee,count(distinct tasks), greatest(max(last_job_date),max(last_position_date))
from job
group by employee
having greatest(max(last_job_date),max(last_position_date)) < 2008-08-28 + integer '1';
I tried to do the following and got the following error message:
select employee,count(distinct tasks)
from job
where greatest(max(last_job_date),max(last_position_date)) < 2008-08-28 + integer '1'
group by employee;
ERROR: aggregates not allowed in WHERE clause
********** Error **********
ERROR: aggregates not allowed in WHERE clause
SQL state: 42803
Is there away around this? Should i create a function to populate a variable that can be used in it's place...will that even work?
