使用 JOOQ 的 SelectQuery 为 JOIN 使用别名

Use alias for JOIN using JOOQ's SelectQuery

我需要使用嵌套 select 编写查询并使用 JOOQ 的 SelectQuery 加入:

    SELECT *
    FROM (select * from 
    "public"."parent" 
    order by "public"."parent"."setup_time" 
    desc limit 10 offset 0) as "parent1" 
    join "public"."child" 
    on "public"."child"."parent_id" = "parent1"."id" 
    where "public"."child"."name" = 'test'

所以,我写了这样的东西:

SelectQuery<ParentRecord> subSelectQuery = context.selectQuery(PARENT);
selectQuery.addJoinOnKey(CHILD, JoinType.JOIN, CHILD.PARENT_ID);

但它会生成 sql 代码,例如

join "public"."child" on "public"."child"."parent_id" =  "public"."parent"."id

如何使用别名 parent1 而不是完整的 table 名称 "public"."child"."parent_id"?

我找到了解决方案。

SelectQuery<ParentRecord> selectQuery = context.selectQuery(subSelectQuery.asTable(PARENT.getName()));
selectQuery.addJoin(CHILD, JoinType.JOIN, CHILD.PARENT_ID.eq(PARENT.as(PARENT.getName()).ID));
