AWS Athena：我们如何在 AWS Athena 中将 integer 值作为带有千位逗号分隔符的字符串

Question

How can we show integer numbers with thousand comma separator.

So, by executing the below statement

select * from 1234567890

How can we get the result as 1,234,567,890

Answer 1

You can achieve this by casting number to string and using regex:

with dataset(num) as (
    values (1234567890),
    (123456789),
    (12345678),
    (1234567),
    (123456),
    (12345),
    (1234),
    (123)
)

select regexp_replace(cast(num as VARCHAR), '(\d)(?=(\d\d\d)+(?!\d))', '$1,')
from dataset

Output:

_col0
1,234,567,890
123,456,789
12,345,678
1,234,567
123,456
12,345
1,234
123
