在 AWS Athena 中将小数转换为货币

Question

我有一个字段 value(decimal(23, 2))，我正在这样查询它：

sum(value) 作为输出我得到 1200000.32

我正在尝试将其转换为货币以获得 .200.000,32，如下所示：

cast(sum(value) as money) == FAIL
sum(value::money) == FAIL
cast(sum(gmv::numeric) as money) == FAIL

如何获得所需的货币类型？

Answer 1

There is no money type in presto. And Amazon's version of presto does not support format and I could not find any buld in function to format numbers. So you will need to either create and use some user defined function 来做到这一点，或者使用一些替换和正则表达式魔法：

WITH dataset(d) AS (
   VALUES 
  (decimal '1'),
  (decimal '999.99'),
  (decimal '1000.1'),
  (decimal '101000.1'),
  (decimal '1000000'),
  (decimal '10001100.10')
 ) 
 
SELECT '$' || regexp_replace(replace(cast(d as VARCHAR), '.', ','), '(\d)(?=(\d{3})+,)', '.')
FROM dataset

输出：

_col0
,00
9,99
.000,10
1.000,10
.000.000,00
.001.100,10
