One way to customize SQLAction is to subclass a query itself
overriding 'createSQLAction'. But this won't work for relationships
Alternatively you can use DataConextDelegate to intercept the queries
and if needed wrap them in a custom decorator that builds the right
SQLAction (check various indirect queries on how the decorator might
look like, e.g. ObjectIdQuery).
