Question

(SELECT *
  FROM remedi.meds_donation
 WHERE state_short_name IN ('TN')
 AND request_date between "2018-10-01 00:55:48" AND "2018-11-29 13:02:14"
)
 union all
 (SELECT *
  FROM remedi.meds_donation
 WHERE state_short_name NOT IN ('TN')
 AND request_date between "2018-09-01 00:55:48" AND "2018-10-29 13:02:14"
)
 ORDER BY request_date DESC

Answer 1

order by必须排在第二位，或者联合必须是子查询

也许你是说

const signUpCall = store.getActions()[0]

expect(signUpCall).toHaveBeenCalledWith({
        email: 'foo@gmail.com',
        username: 'foo',
        password: '12345678'
      });

但我认为更好

SELECT * FROM (

(SELECT *
  FROM remedi.meds_donation
 WHERE state_short_name IN ('TN')
 AND request_date between "2018-10-01 00:55:48" AND "2018-11-29 13:02:14"
)
 union all
 (SELECT *
  FROM remedi.meds_donation
 WHERE state_short_name NOT IN ('TN')
 AND request_date between "2018-09-01 00:55:48" AND "2018-10-29 13:02:14"
)

) T ORDER BY request_date DESC

Answer 2

尝试

 SELECT *, (CASE WHEN state_short_name IN ('TN') then 0 else 1 END) as state_order
   FROM remedi.meds_donation
    WHERE request_date between "2018-10-01 00:55:48" AND "2018-11-29 13:02:14"
 ORDER BY state_order asc, request_date DESC

如何将以下查询转换为jpa？
