To remove a primary key constraint, you can use the ALTER TABLE statement and specify the DROP PRIMARY KEY keyword. The specific steps are as follows:<\/p>\n

    \n
  1. First, connect to the MySQL database.<\/li>\n
  2. Remove primary key constraint using the following syntax:<\/li>\n
  3. Remove the primary key from the table named table_name.<\/li>\n
  4. In the above syntax, replace “table_name” with the name of the table from which you want to remove the primary key constraint.<\/li>\n
