Hi,

Within Management Studio -> Edit table, is it safe to change nchar(2000) to nvarchar(2000) without losing data?

Thanks,

Rich

yes, it is safe.
normally, you do an UPDATE of the table (all rows) to trim away the trailing spaces from the nchar, though, because the change of the data type will not do that implicitly.
