I am designing a table that will store login information, which includes a persons name.
There will be lots of inserts and deletes to this table, but no updates.
I am wondering what is the best datatype to use? varchar(50)? nchar(50)?
Optimise for speed, need names in various languages.
The safest way is to use nvarchar. That way you can accept names in multiple languages.
