Removing Commas and Spaces from Field

Question

I have a table called TableD1 in a database with a field called "Range".
The ranges are like 1-1000; 1001-2000; etc. up to like 1000000-200000.
That is how they are supposed to look, they are not numeric fields, just general, containing a low, a dash and a high all in the same field.
I just discovered that quite a few of the entries have included commas and spaces, like 1-1,000 or 100000 - 200000.
I need to write a Query that will remove all of the commas from the data in TableD1's "Range" field, then all of the spaces.
I imagine they are some kind of Update statements but because of the potential to blow up the whole thing, I'm reluctant to experiment.
Does anyone know what code I should use?
Thank you in advance for any help.

Answer 1

Making sure you've taken a backup. Pull the data into temp table and do the testing. once you satisfied with the output then do the update on the main table.
create table #temp
Range varchar(100)
insert into #temp values('1-1,000'),('100000 - 200000')
select replace(replace(Range,',',''),' ','') from #temp
--update #temp set Range=replace(replace(Range,',',''),' ','')
Validate the the output of the select statement.
