Hi all,

I'm trying to create a deferrable foreign key constraint, according to the knowledge base article at https://kb.askmonty.org/en/constraint_type-foreign-key-constraint/. The syntax of "deferrable initially deferred" doesn't seem to be recognised. Without it, the tables are created just fine. I'm using MariaDB 5.5.31. Example:

create table one (

id int primary key

);

create table two (

id int primary key,

one_ref int,

constraint fk foreign key(one_ref) references one(id) deferrable initially deferred

);

=> error: 

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'deferrable initially deferred

)' at line 4

Any idea what's wrong? Is this only supported in MariaDB 10.x?

Thanks!

Best regards

Joeri Leemans
