I want to have the following query in sqlalchemy: SELECT t_objects_1.tid AS t_objects_1_tid FROM t_objects AS t_objects_2 INNER JOIN c_objects AS c_objects_1 ON t_objects_2.tid = c_objects_1.tid INNER JOIN t_objects AS t_objects_1 ON t_objects_1.tid = t_objects_2.parent_id WHERE c.id = 1;
this would return a list of parent_ids whose childs match a certain condition... I would go like the following: s.query(t_objects_1.tid).join((c_objects, t_objects_2.tid == c_objects.tid),(t_objects_1, t_objects_1.tid == t_objects_2.parent_id)).filter(c_objects.id == 1).all() ...but I get this error: (OperationalError) (1066, "Not unique table/ alias: 't_objects_1'") so sqlalchemy is putting the wrong alias in the from clause: SELECT t_objects_1.tid AS t_objects_1_tid FROM t_objects AS t_objects_1 INNER JOIN c_objects AS c_objects_1 ON t_objects_2.tid = c_objects_1.tid INNER JOIN t_objects AS t_objects_1 ON t_objects_1.tid = t_objects_2.parent_id WHERE c.id = %s' how can I bring sqlalchemy to use 't_objects_2' instead of 't_objects_1'? Due to project constraints I have to use sqlalchemy==0.5.6 if maybe this is a known bug of 0.5.6 please let me now -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
