Let’s create a new database table by writing a native SQL query in phpMyAdmin or Sequel Pro. The intent of this episode is (1) to give you an appreciation of the schema that defines each database table and (2) to prepare you the next episode about how WordPress creates each of the database tables.
You are actively writing the schema that will define a new custom database table. Don’t worry. Tonya walks you through each step and explains it. She also gives you insights and her thought processes.
You’ll learn about specifying default values, primary keys, and foreign keys.
|CREATE TABLE ktc_videos(|
|id BIGINT(20) unsigned NOT NULL AUTO_INCREMENT,|
|post_id BIGINT(20) unsigned NOT NULL DEFAULT 0,|
|video_id VARCHAR(200) NOT NULL,|
|PRIMARY KEY (id),|
|KEY post_id (post_id)|
|DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;|
There’s a time to code and …. yup, that sums it up.
