create a foreign key allowing one to one tables relationships

Our Primary Key and Foreign key constraints always have allowed creaing and ensuring '1 to many' table relationships. After researching, there is no direct way to implement such a case with Informix. The only safe way is to create a primary key on the 'parent' table, a unique index on the 'child' table plus a trigger with references that will catch insert and delete. This trigger will fire a SPL that will count the rows in the parent table matching the new key. If 1 row, the child row is created, else the SP returns an error. Same principle for DELETE

    All you have to do is to create a PRIMARY KEY or UNIQUE constraint on the child table's foreign key column that points back to the parent table. Then the child table can only have a single row that references each parent table row. No need to formalize this in syntax!
