--- Comment #3 from José Antonio <fal...@reisng.eu> --- Thanks for the link to 47055 and pointing to 37702. It seems that all the problems related to postgresql are rooted on creating data sets that are not compatible with the operations that smw wants to excute on them. Indeed in this case mysql seems to enable outer joins on nullables. Here It seems that the most more straight approach would be set “not null” for fields that are used in outer joins. Regards.
