I’m trying to work out an average grade from a database file using the ‘Do Loop’ method; I’m completely clueless how to even start it. Does anyone have any tips or is able to help me?
Regards, Jack.
Rather than looping in vb, calculate the average in SQL.
E.g.,
select StudentID, avg(Grade) as AverageGrade
from StudentGrade
group by StudentID

I am trying to find the parent with the most children. I feel like this should not be so hard however I find myself struggling.
I am using postgresql and Ltree.
Thank you
It's the same logic as for any other case, find a function that will give you the parent and group by it. This should work:
SELECT subpath(path,0,1), count(*)
FROM test
GROUP BY subpath(path,0,1)
ORDER BY count(*) DESC limit 1;

I'm sorry, but I'm not sure if this is the right place to ask. But is there anyone out there that can teach me a step by step guide on how to use OpenLdap? There isn't any GUI and I'm unfamiliar with it. I'm trying to create a user in there.
Thanks in advance. :)
