MySQL uses foreign key constraint instead of inheritance. MySQL does not support table inheritance.
You can achieve the same with the help of foreign key constraint. Let us create a table and use the foreign key constraint. The query to create the first table is as follows −
mysql> create table Parent_Table -> ( -> ParentId int, -> PRIMARY KEY(ParentId) -> ); Query OK, 0 rows affected (3.59 sec)
Now create the second table. The query to create the second table is as follows −
mysql> create table Child_Table -> ( -> ChildId int references Parent_Table, -> PRIMARY KEY(ChildId) -> ); Query OK, 0 rows affected (0.73 sec)
Now add the foreign key relationship between two tables. The query is as follows −
mysql> alter table Child_Table add constraint FK_Child Foreign key(ChildId) references Parent_Table(ParentId); Query OK, 0 rows affected (2.28 sec) Records: 0 Duplicates: 0 Warnings: 0
