MySQL错误1064连接3表查询

Question

SELECT *
FROM employee e FULL OUTER JOIN salarydetails s ON (e.Eid=s.Eid)
WHERE s.Month="January" AND e.Eid="0002"
UNION
SELECT *
FROM salarydetails s FULL OUTER JOIN bonus b ON (s.Eid=b.Eid)
WHERE b.Month="January" AND b.Eid="0002"

我有3个表：employee，salarydetails和bonus。我正在编写一个Java代码来加载JTable。我必须从这三个表中获取数据。我试图使用的查询是上面的查询。但它会给出错误。我该怎么办？
