我遇到了与车辆速度相关的问题,我从select distinct storecode from stocks where storecode not in (select distinct storecode from stocks where supplier = 'S2') 库调用了getSpeed函数,但总是得到0.我还使用自定义函数获取位置但运气不好,请帮帮我!!!
select distinct storecode from stocks where storecode not in (select distinct storecode from stocks where supplier = 'S2')
getSpeed
