Add support of referential constraints directly in column defininions: create table t1 (id1 int primary key); create table t2 (id2 int references t1(id1)); Referenced field name can be omitted if equal to foreign field name: create table t1 (id int primary key); create table t2 (id int references t1); Until 10.5 this syntax was understood by the parser but was silently ignored. In case of generated columns this syntax is disabled at parser level by ER_PARSE_ERROR. Note that separate FOREIGN KEY clause for generated columns is disabled at storage engine level.
