I've tried to join some tables(multiple times) and i've used something like CITY.Of(CCY).As(CURRENT_CITY) but without success. Actually it works but i have to create aliases for tables and i don't know how to do it with SqlExp
Create SqlIds.
SqlId CURRENT_CITY("CURRENT_CITY");
or
SQLID(CURRENT_CITY); // Same, using macro to duplicate id
