如何用jooq编写连接获取查询？

Question

Anyone knows how to write join fetch query with jooq ? my code :

int oid=5;
Select<?> selectQuery = DSL_CONTEXT.select().from(TABLE_A)
      .join(TABLE_B).on(TABLE_A.PID.eq(TABLE_B.ID))
        .where(TABLE_A.OID.eq(oid))
        .orderBy(UPDATED.asc(), ID.asc())
        .seekAfter(val(offsetDateTime), val(id))
        .limit(50);

this results in : select * from table_a join table_b type of query. How to make it create a query of following type :

select * from table_a join fetch table b ...

Any help is appreciated.

The closest you can get with jOOQ 3.11 out of the box functionality is using ResultQuery.fetchGroups() . On your query, call:

Map<TableARecord, Result<TableBRecord>> result = select.fetchGroups(TABLE_A, TABLE_B);
