Find Out The Columns Should Be Referred Through Foreign Key

For example if we clearly define a foreign key in the master and child table as following script -

CREATE TABLE master(pkey int PRIMARY KEY, data varchar(10))
GO
CREATE TABLE child (fkey int CONSTRAINT fk_master_child
FOREIGN KEY (fkey) REFERENCES master(pkey))


We can find out the two tables reference relationship by looking at INFORMATION_SCHEMA tables.

However, if the two tables are created in this way €“


CREATE TABLE master(pkey int PRIMARY KEY, data varchar(10))
GO
CREATE TABLE child (fkey int)


Does any one know how to programming verify the actual reference relationship exists between pkey and fkey in these two tables?


Thanks
