Good to know and looks like it might fix my problem. Except that
MySQL doesn't support WO's syntax for outer joins.
You should be able to correct this by sub-classing
com.webobjects.jdbcadaptor.MySQLPlugIn and
com.webobjects.jdbcadaptor.MySQLPlugIn.MySQLExpression.
Done and working. Just adapted Project WONDER's postgresql plugin.
I'm still not 100% on the join semantics, I had to make it
EOLeftOuterJoin for the to-Many relationship and the to-one
relationship in the join table for both directions. Does anybody
have good documentation as to what the proper usage of the join
semantics from an enterprise object perspective and not SQL? Or
does that even make sense.
This is one of the less well illuminated corners of EOF. The various
plugins are the best source of information.
