我是Bookshelf.js和knex的新手.我需要在Bookshelf/knex中编写与此相当的查询

SELECT Inv.*, Comp.* 
FROM  Inv,   Comp
WHERE Inv.uId =2 AND Comp.cId = Inv.cId;

Inv Table有:

Id     |  primary key, integer  not null
col1   | string data
cId    | integer, foreign key references C table
uId    | integer  foreign key reference U table      

Comp Table有:

cId     |  primary key, integer  not null 
col3    | string data
