MySQL中沒有FULL OUTER JOIN的處理

FULL OUTER JOIN:
SELECT column_name(s)
FROM table1
FULL OUTER JOIN table2
ON table1.column_name=table2.column_name;

Mysql中可以使用UNION,同時聯合LEFT JOIN 與RIGHT JOIN，如：

SELECT column_name(s) FROM table1 LEFT JOIN table2 ON table1.name = table2.name

UNION

SELECT column_name(s) FROM table1 RIGHT JOIN table2 ON table1.name =table2.name;
