objectType FKColumn

A pair of columns that are used to join two tables. To do an inner join of data from the two tables, a query should include a constraint that sets the value from the first column equal to the value in the second column. This type assumes that it is used in the context of implied source (i.e., current) and target tables, as in the ForeignKey type's fkColumn.
