FULL OUTER JOIN con SQLite

Question

SQLite ha solo INNER e LEFT JOIN.

C'è un modo per FULL OUTER JOIN con SQLite?

Answer 1

Sì, vedere l'esempio su Wikipedia.

SELECT employee.*, department.* 
FROM employee 
     LEFT JOIN department 
      ON employee.DepartmentID = department.DepartmentID 
UNION ALL 
SELECT employee.*, department.* 
FROM department 
     LEFT JOIN employee 
      ON employee.DepartmentID = department.DepartmentID 
WHERE employee.DepartmentID IS NULL 

Answer 2

seguito il commento di Jonathan Leffler, qui è una risposta alternativa a quella di Mark Byers':

SELECT * FROM table_name_1 LEFT OUTER JOIN table_name_2 ON id_1 = id_2 
UNION 
SELECT * FROM table_name_2 LEFT OUTER JOIN table_name_1 ON id_1 = id_2
