Let’s say I have 67,828 records in my current database without Primary Key & AUTO_INCREMENT

Now I want add one column name ID as primary key, AUTO_INCREMENT and starting with number 5000.

Current DB

Name Email
--------------------
John  john@doe.com
Peter peter@john.com

New format should be

ID   Name Email
--------------------
5000 John  john@doe.com
5001 Peter peter@john.com

Try this one –

ALTER TABLE table_name
  ADD COLUMN id INT(11) NOT NULL AUTO_INCREMENT FIRST,
  ADD PRIMARY KEY (id),
  AUTO_INCREMENT = 5000;
