T2."savetemplate_id" AND
t0."savedtemplate_id" = T1."savedtemplate_id" ORDER BY t0."name"
COLLATE INFORMATION_SCHEMA.CASE_INSENSITIVE ASC"
Why is this not working and is:
(usersavedtemplate.user.usernode.node=savedtemplatenode.node)
generating:
(1=1)
Is it possible to work with relations that way?
I have seen that before, but I don't recall the cause. It _should_
work, if
(usersavedtemplate.user.usernode.node=savedtemplatenode.node) is
getting translated into a EOKeyComparisonQualifier. One possibility
is that your model is not as you think it should be. It may be that
EOF is determining that both sides of
(usersavedtemplate.user.usernode.node=savedtemplatenode.node) refer
to the same column in the same row that it is optimizing it to 1==1.
