Hi,

Is AccInvQty a charfield? Then you could use select sum(cast(replace(AccInvQty,',','.') as decimal)) from ItemDetails. Otherwise can you show us your error?

1) solve the problem of . or , : you have to check your application that is generating the rows. if the application is using the system settings then if one of the systems is configured to use , then you will get this. if you are using .Net applicaiton to access the DB then use the culterinfo for hadling the . or , issues
