问题 I am using QueryDsl SQL and I want to left join a subquery. Here is the query in plain SQL SELECT usr.memberId, payoutsBbf.totalPyts FROM users usr LEFT JOIN (SELECT pyt.member_id AS mmb_id, SUM(pyt.amount) AS totalPyts FROM payout pyt WHERE pyt.payoutPeriod < '2018-01-01' GROUP BY pyt.member_id) AS payoutsBbf ON usr.id = payoutsBbf.mmb_id I wish to write it in QueryDsl SQL and is almost important that the subquery is left joined to the main table users coz this is just a snippet of the whole

问题 How to use select straight_join ... from ... in hibernate/jpa? 回答1: There is no straight_join for JPQL/JPA.

问题 MyBatis provides the mapping, local cache, and logging out of the box. QueryDSL / jOOQ provide compile-time check of SQL statements and IDE auto-completion as a result. Is it possible to combine them? In other words, I would like to create a query with either QueryDSL or jOOQ, and then execute it with some glue code/adapters with MyBatis . What I have already checked: I considered to generate SQL query strings with QueryDSL and use them in MyBatis with its '@SelectProvider' annotation, but it

问题 I would like to use the yearweek() function of QueryDSL, which is supported by QueryDSL. This function generates the query select year(table1.timestamp)*100 + week(table1.timestamp) as col_0_0_ [...] . This does, however, not return a correct result on year endings. I've already opened a bug report for this issue. I would rather use the built-in SQL yearweek() function, which is directly supported by e.g. MariaDB. Is there a way of using the SQL function YEARWEEK(timestamp) with QueryDSL? Or

问题 I have a score table where I have players scores, and I want select unique records for each player with the biggest score.

Expected result: id | player_id | score | ... 2 | 2 | 21 | ... 3 | 3 | 9 | ... 4 | 1 | 30 | ... I can achieve that with pure SQL like this: SELECT * FROM player_score ps WHERE ps.score = ( SELECT max(ps2.score) FROM player_score ps2 WHERE ps2
