How to remove constraints from my MySQL table?

Question

I want to remove constraints from my table. My query is:

ALTER TABLE `tbl_magazine_issue` 
DROP CONSTRAINT `FK_tbl_magazine_issue_mst_users`

<

Answer 1

The simplest way to remove constraint is to use syntax ALTER TABLE tbl_name DROP CONSTRAINT symbol; introduced in MySQL 8.0.19:

As of MySQL 8.0.19, ALTER TABLE permits more general (and SQL standard) syntax for dropping and altering existing constraints of any type, where the constraint type is determined from the constraint name

ALTER TABLE tbl_magazine_issue DROP CONSTRAINT FK_tbl_magazine_issue_mst_users;
