sql - Conversion fails when trying to Convert string to int

Question

I have some sales numbers in a string column that I need to convert to some format so that i can calculate them with each other but I get this error while trying to convert them.

Conversion failed when converting the varchar value '-6.353,35' to data type int.

I'm not allowed to lose any money by rounding it up. It doesnt mather but in what type i convert as long as im not rounding them up. What's your thoughts?

For example i have -6.353,35 and 300,30 and i want to sum them too -6.053,05

Answer 1

try this...

select convert(int,convert(float,replace('-6.353,35',',','')))

as there are (,) Commas it cannot be converted to float,so remove the (,)commas after converting to float we can convert to int

If you want decimal values, then you should use float

select convert(float,replace('-6.353,35',',',''))

Edit Like @marc_s suggested, it is preferred to use decimal rather than float

select convert(decimal,replace('-6.353,35',',',''))
