Insert sequential number in MySQL

Question

I added an empty column to a table and now I want to insert sequential numbers to its rows. Is it possible to do it using SQL?

Answer 1

try this auto increment if you wanted to have incremental number in your table for each insert that you do

create table WithAutoInc(somID int AUTO_INCREMENT,somName_ char(100) ,primary key(somID ));

now to insert you can do this

 insert into WithAutoInc (somName_) values ('presley');

the result is
