Question

the .................. data type can be used to store the email address​

Answer 1

VARCHAR is the best data type to be used for email address as Email vary a lot by length. NVARCHAR is also analternative but I would recommend it to use only if the email address contains extended chars and keep in mind that it requires double amount of storage space as compared to VARCHAR .

Answer 2

"Varchar2" is a data type which is used to store the email address field on the database

Explanation:

• The varchar is a data type that is used to store the character type data and the mail id is also a charter type data. It is because there is no specified character for mail except @. It means the mail data can contain @gmail or @yahoo which is not specific.
• The character is also used to store with the help of char data type but it fixes the memory if there is only some character, but the varchar2 is used to fix up to that memory which is filled by the data.
• Hence varchar2 is used for the mail field to store the data on the memory.
