Can I have an MySQL database auto-assign a value to a column after an insert statement?
问题 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? 回答1: Create your table with an identity autoincrement column: CREATE TABLE table_name ( id INTEGER AUTO_INCREMENT PRIMARY KEY, -- other columns to follow ) 回答2: You want auto increment column. You can refer to the documentation here: http://dev.mysql.com
