Manav Pandya · Answer

Hello Yes you can use this , but its not recommended to use in real time scenario Reason is that if you provide n number of value to column and not providing sufficient value than extra space will be un-useful or empty Which is bad habit to follow , so in this case you can specify appropriate number of maximum value to any type would be baneficial Like : First name nvarchar(60) // May not reach upto 60 chars OR If you want maximum value than you can specify : FirstName nvarchar(MAX); // takes max size and empty if not provided sufficient value So its recommended to use space wisely , which indirectly help you in performance Thanks

It can store maximum 8000 Non-Unicode characters. So n varies from 1 to 8000

Hi Gajanan, Varchar(n) - Till that specific length your value can hold the data. It can be used for the fixed values. Maximum - 8,000 Characters https://docs.microsoft.com/en-us/sql/t-sql/data-types/char-and-varchar-transact-sql
