Search for a decimal and then remove it from string

Hello,
I need a T-SQL Statement to search a string variable for a decimal and
then remove it.

@string = '1234.5'

I want @string to equal '12345'

If I do it this way:
Set @string = replace(@string, '.', '')

I would assume it would remove the decimal in the string.

What if @string = '12345', with no decimal?

Would it not work and set @string = NULL, due to not finding a decimal within the
replace statement?

Thanks.

Hello,

No, it will work as you listed and will NOT nullify the string just because the searched for item is not there.

If @string is null it can still cause other issues, so if you haven't already accounted for that elsewhere here's the line:

Set @string = ISNULL(replace(@string, '.', ''),'');

Thanks,
Chris

it will keep the same number: if it has something replace - it will replace

<Would it not work and set @string = NULL, due to not finding a decimal within the
replace statement?>
No, unless you wish -- it is extra code
