Question

Given a table employee with columns ID(pk) and name

ID|name
--+-----
1 |John
2 |James
3 |Tom

Can I do

INSERT INTO employee (name) VALUES (Jack);

and somehow have the database auto assign the next available ID? Can a trigger do it? If so, how?

Answer 1

Create your table with an identity autoincrement column:

CREATE TABLE table_name
(
   id INTEGER AUTO_INCREMENT PRIMARY KEY,
   -- other columns to follow
)
