如何在hibernate中进行外连接

Question

这是我的SQL查询

SELECT * FROM candidate A
LEFT JOIN form B ON A.canid = B.canid
UNION
SELECT * FROM candidate A
RIGHT JOIN form B ON A.canid = B.canid

Answer 1

jpa中的连接与sql jdbcTemplate中的连接相同。加入上面的查询很好

SELECT * FROM候选人A
左外联接B在A.canid = B.canid上 UNION
SELECT * FROM候选人A
A.canid = B.canid

上的右外部联接B.
