I want to remove constraints from my table. My query is:
ALTER TABLE `tbl_magazine_issue` DROP CONSTRAINT `FK_tbl_magazine_issue_mst_users`
For those that come here using MariaDB:
Note that MariaDB allows DROP CONSTRAINT statements in general, for example for dropping check constraints:
ALTER TABLE table_name DROP CONSTRAINT constraint_name;
