Snowflake 2 decimal places - snowflake-cloud-data-platform

Question

I have a data column that is a number and it has nulls, dashes, and commas. I want to remove all and replace with 0.00. Also I have some numbers that are 11.4 instead of 11.40. How do I fix this?
also something either nvl or round adds the comma back in.
I tried round, I tried doing ;;decimal(20,2), I tried a replace to 0.00. Nothing seems to work.
round(nvl(replace(replace(aum_total,'-',0),',',''),0)) as aum_total

Answer 1

so you are converting dash to zero makes low sense, from a guessing intent.
and the coma point I assume to to remove thousands, so to add that back in needs to be done via TO_CHAR via formatting.
And the trailing zeros also is a formatting thing..
select
column1 as aum_total
,translate(aum_total, '-', '0') as t1
,replace(t1, ',', '') as r1
,zeroifnull(r1) as z1
,to_number(z1, 20, 2) as n1
,to_char(n1, '9,999,999.00') as result
from values
(null),
('1-7'),
('1,8'),
('11.4'),
('11.40'),
('11.400'),
('11.1234'),
('1,234.567');
gives:
AUM_TOTAL
T1
R1
Z1
N1
RESULT
null

0.00

Thinking about this more, I now assume you mean you want to replace a string that is only a dash, with zero, as that is standard accounting, and not all dashes, thus not mess-up negative numbers, so swapping to regexp_replace, and the number cast can be skip it seems also!
select
column1 as aum_total
,trim(aum_total) as t1
,regexp_replace(t1, '^-$', '0') as r1
,replace(r1, ',', '') as r2
,zeroifnull(r2) as z1
,to_char(z1, '9,999,999.00') as result
from values
(null),
(' - '),
(' -10.123 '),
('-'),
('-10.123'),
('1,8'),
('11.4'),
('11.40'),
('11.400'),
('11.1234'),
('1,234.567');
