java - 如何在查询 DSL 中编写复杂的 SQL 查询

Question

我尝试计算特定产品占产品总数量的百分比。我写了一个运行良好的 SQL 查询。但是当我尝试用 Query DSL 编写时，我遇到了一个问题，我真的很难编写这种查询。

SELECT ROUND((c.v2/f.v1)*100,2) , MONTH AS RESULTt
FROM
(SELECT SUM(Quantite)as v1,MONTH  FROM Total_sold_view WHERE id_company='379' AND
year=2009 GROUP BY MONTH ORDER BY MONTH ASC) f,
(SELECT Quantite as v2,MONTH FROM Total_sold_view  WHERE id_company='379' AND year=2009
AND product_type=13 ORDER BY MONTH ASC) c
WHERE c.MONTH=f.MONTH
