To update an existing SQL table in phpMyAdmin to match the new structure, you'll need to use SQL ALTER TABLE statements. Here’s how you can do it for each part of your table:

1. Add new columns:

sql
Copy code
ALTER TABLE blog_post
ADD COLUMN endpoint VARCHAR(200) NOT NULL,
ADD COLUMN img_url TEXT,
ADD COLUMN Field8 INTEGER,
ADD COLUMN excerpt VARCHAR(255);

1. Modify existing columns: Make sure that the data types and constraints of existing columns are as needed. For instance, if the title column already exists and needs to be unique, you can ensure this constraint is set:

sql
Copy code
ALTER TABLE blog_post
MODIFY title VARCHAR(100) NOT NULL,
ADD UNIQUE (title);

1. Remove unwanted columns (if applicable): If there are columns that are no longer needed, you can drop them:

sql
Copy code
ALTER TABLE blog_post
DROP COLUMN old_column_name;

1. Set the primary key: If the primary key is already set correctly, you don't need to do anything. If you need to ensure that the id column is the primary key, you can use:

sql
Copy code
ALTER TABLE blog_post
ADD PRIMARY KEY (id);
