I guess I don't know exactly. Is the WO stack responsible for

generates outer joins with legacy syntax (correctly). The Frontbase
db server just doesn't interpret it right. I emailed Frontbase a
while back about it and they acknowledged it and told me to use the
newer join syntax.
Generally, the plugin provides information and services to the JDBC
adaptor to generate / tweak the SQL that is generated. See
com.webobjects.jdbcadaptor.JDBCPlugIn. Most of the tweaking is done
in a subclass of com.webobjects.eoaccess.EOSQLExpression specific to
the database. The plugin contains a subclass of EOSQLExpression in
which there are methods such as assembleJoinClause(String leftName,
String rightName, int semantic) that the plugin can implement to
create the correct syntax.
So, to me, this sounds like a defect in the FrontBase plugin.
