name of foreign key in innodb table

Hello,

I'm trying to do a ALTER TABLE to add a foreign key. The code is:

execute "ALTER TABLE table1                                 ADD CONSTRAINT FOREIGN KEY `const_fk_table1_table2_id` (`table2_id`)                                 REFERENCES `table2` (`id`)                                 ON DELETE CASCADE"

Instead of creating a foreign key constraint with the name "const_fk_table1_table2_id" it will create one with the name "table2_ibfk_1".

First I've added an index with : add_index :table1, :table2_id, :name => 'fk_table1_table2_id'

Am I doing something wrong?

Problem fixed. The name comes after the CONSTRAINT not the FOREIGN KEY keywords.
