Hi, I have four tables that I would like to join algorithmically. Element with element_prop, elementprop with element_typeprop in one direction and element with element_type in the other. I would like to do this in one line as I am concerned about the number queries must be minimal given I am working in a gigantic database.
q=session.query(element).outerjoin(element_prop,element.element_id==element_prop.element_id).outerjoin(element_prop,element_type_prop.element_type_prop_id==element_prop.element_type_prop_id).outerjoin(element,element_type.element_type_id==element.element_type_id) I replicate the format I'd use for native SQL. However, I come across aliasing issues: ERROR 1066 (42000): Not unique table/alias: 'element_prop' when I run the generated SQL code, even though sqlalchemy doesn't prompt any error messages. I would like to find out an efficient and robust way of joining these tables the way I described. What would be the best solution given my concerns? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
