HIVE 中的拆分功能

Question

我想将地址分成两列，即街道编号和街道名称，例如 从客户那里选择地址1

前任的地址看起来像

2719 STONE CREEK DR

并将它们存储到街道编号为

2719

和街道名称为

STONE CREEK DR

。

使用

split(address1 ,'[\ ]')[0]

不仅可以分割街道。

这只是我们用来查看数据的 select 语句。

样本数据：

address1
100 HORACE GREELEY RD  
55 School Street
2893 MASHIE CIR
1200 JEWEL DR
201 W RIVER RD
