Development Tools Database Foundations Joining Relational Data Between Tables in SQL Keys and Auto-Incrementing Values

Is the computer blind ?

It tells me it doesen't see the primary key and I wrote : CREATE TABLE t_genres (pk_id AUTO_INCREMENT PRIMARY KEY , uk_id VARCHAR(45) UNIQUE KEY )

  1. You didn't specify the type for pk_id (Integer)
  2. uk_id should be uk_name
  3. uk_name is needs a NOT NULL
CREATE TABLE t_genres (pk_id INTEGER AUTO_INCREMENT PRIMARY KEY,uk_name VARCHAR(45) NOT NULL UNIQUE KEY);

I've figured it out myself , thanks anyway , It might help someone in the future ;)
