Question

I am using MySQL for my database. I have a requirement to store a list of users in the system. The user will have both first name and last name.

I cannot have the first name and second name as the primary key. So I need a indexing key. But I do not want to enter the index value every time to add a new row.

I want the system to handle this with auto increment of previous value every time I try to add a new user. Please let me know how to do this.

Also I am supposed to do a search operation on the list of user with the first name. Please let me know the efficient way to do the search as the number of records could be more than a million.

Answer 1

create table users (
 id int primary key auto_increment,
 name varchar(64),
 ...
)
