Create foreign key using Phpmyadmin

The innodb storage engine supports foreign keys in Mysql.

To create foreign keys in phpmyadmin :

1. Convert both tables into innodb, if they are not already.

2. View the structure of the table which will have a foreign key. Make the referencing field an INDEX.

3. Now come back to structure view and click Relation view.

In the Relation view page the field (which was made an INDEX) can be made a foreign key referencing to some other field in another table.

That should do it.

  • slevon

    this is great!
    But I experienced that all my relations will be lost when I export and import the db.
    Do you know a way to keep this relations alive after a backup/restore process?

    Best wishes,

      If you use mysqldump then foreign keys are kept intact in the table definition.
      If you restore over existing tables (which dont have foreign key relation) then you need to drop tables so that fresh tables are created again with the correct foreign key relations.
