Description: Nested views working on same set of data on 8.1.21 but
not on 8.4.4
Details:
Hello,
I have migrated a 5 years old database from 8.1.21 running on top of centos
5.5 on an i686 to 8.4.4 running on top of centos 5.5 on an x86_64
architecture.
I have some nested views and i am still able to get the results on 8.1.21
but when it comes to 8.4.4, I can get the results only from views that
references other tables but when the view references other views, I get an
empty result set.
I also noticed that a view (not nested) gives an empty result set on 8.4.4
while it gives exactly what it is expected to on 8.1.21. This is a simple
view for giving some pseudo-random data for an exam.
it's definition is as follows:
What other data should I post to get some help? There is no confidential
data on the database so I can send schema definition and data but this is a
huge amount for a web form.
