So, to answer my own question, because I ran into this issue again (and yeah I forgot this).
It works fine for properties on itemtypes that have actual relations in the database, i.e. source_id on a item_type that has a relation to another table.
Data_source on the other hand, does not have a relation to other tables, because data_source can be of type List as well, therefor a SQL WHERE statement wouldn't work that well on the data_source column/property
