One other avenue to pursue is whether EOKeyValueQualifier is
suitable for the sort of query you are doing:
EOKeyValueQualifier
("primaryapprovers.employee",EOQualifier.QualifierOperatorEqual,
someEmployee)
Maybe
ERXExistsQualifier
(EOKeyValueQualifier("employee",EOQualifier.QualifierOperatorEqual,
someEmployee), "primaryapprovers")
I just wanted to follow up and say that this contraption qualifier
works. Thanks for a workable solution Chuck. If I ever make a
WOWODC, I am now up to about 6 beers owed.
I suspected that might be it. Several of the qualifiers only generate
the correct SQL within a set of boundaries and none tell you when you
stray outside. EOKeyValueQualifier and to-many relationships are
often problematic. That is one of the reasons these other qualifiers
were created.
