thinkjs中自定义sql语句

一直觉得在使用thinkjs时，只能是它自带的sql语句查询，当遇到相似于这样的sql语句时，殊不知道这该怎样来写程序，却不知原来thinkjs能够执行自定义sql语句

SELECT * from adinfo WHERE 1481286720 BETWEEN stime AND etime OR (1481297520 BETWEEN stime AND etime)

model.query(...args) 
•return {Promise} //指定 SQL 语句执行查询。

至关于：

let addCheck = await this.model('adinfo').query('SELECT * from adinfo WHERE ' + stime + ' BETWEEN stime AND etime OR (' + etime + ' BETWEEN stime AND etime)');

完整版就是这样的：

let postDatas = this.post();
let stime = postDatas.stime;
let etime = postDatas.etime;
// SELECT * from adinfo WHERE 1481286720 BETWEEN stime AND etime OR (1481297520 BETWEEN stime AND etime)
// let addCheck = await this.model('adinfo').where({stime:['between', 'stime,etime'],etime:['between', 'stime,etime'],_logic:"OR"}).select();
let addCheck = await this.model('adinfo').query('SELECT * from adinfo WHERE ' + stime + ' BETWEEN stime AND etime OR (' + etime + ' BETWEEN stime AND etime)');

原来，thinkjs仍是那么的神秘~
