I have a table that is labeled as a nvarchar and it contains only numbers, I want to do a query like below (sum) but I get error because its a nvarchar field.

select sum(startingbid) as totalvaue from items

The sum or average aggregate operation cannot take a nvarchar data type as an argument.

changing the column to an int is not an option...

Note: if there are any non-numeric characters in this field, you will get an error. You really need to move towards storing your data in the correct type.

I understand this, but this has gone live already and there is not much of a choice, plus this is just a pilot project...
turns out...int wont work because there are decimal values....
so change I just int to decimal and it will be good?
