EnumReferencedTables Method
В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.
The EnumReferencedTables method returns a QueryResults object that enumerates tables on which a PRIMARY KEY or UNIQUE constraint is defined.

Description |
|---|---|---|
candidate_key |
nvarchar(129) |
Not applicable. Contains the string N/A. |
candidate_table |
nvarchar(262) |
Name of the table on which the PRIMARY KEY or UNIQUE constraint is defined. |
referenced |
bit |
When 1, the table referenced by the Table object used depends on the result-set listed table in a FOREIGN KEY relationship. |
Замечания
When IncludeAll is TRUE, the result set enumerates all tables on which PRIMARY KEY and UNIQUE constraints are defined. The value of the referenced column in the result set determines table object dependency on the table listed in the result set.
When IncludeAll is FALSE (default), the result set enumerates only those tables that contain PRIMARY KEY or UNIQUE constraints and on which the referenced table depends.
