请问如何select 出一个函数的多个输出
def func(Open,High,Low,Close,20)
xxxxxxxxxxxxxxxxxxxxxxxx
return x,y
t=select TimeStamp,func(Open,High,Low,Close,20) as factor from xxx
因为一个函数就可以计算出里面需要的结果 如果写很多函数同样的计算过程会很浪费时间
比如 t=select TimeStamp,funcA(Open,High,Low,Close,20) as factorA,funcB(Open,High,Low,Close,20) as factorB, from xxx
