Reference columns which may be associated with the constraint. For example, if the constraint is a FOREIGN_KEY, this represents the list of full names of referenced columns by the foreign key.
↳ reference_table
string
Reference table which may be associated with the constraint. For example, if the constraint is a FOREIGN_KEY, this represents the list of full name of the referenced table by the foreign key.
↳ table_name
string
Table which is associated with the constraint. In case the constraint is defined on a table, this field is left empty as this information is stored in parent_name. However, if constraint is defined on a view, this field stores the table name on which the view is defined.
