Name of foreign key in innodb table


#1

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.
