后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能,并着手修改当前还在使用该功能的应用程序。

The EnumReferencingTables method returns a QueryResults object that enumerates user-defined tables on which a FOREIGN KEY constraint is defined.

语法

Parts

  • object
    Expression that evaluates to an object in the Applies To list.

  • IncludeAll

A QueryResults object that contains one result set defined by these columns.

Column

Data type

Description

candidate_key

nvarchar(129)

Not applicable. Contains the string N/A.

candidate_table

nvarchar(262)

Name of a table on which a PRIMARY KEY or UNIQUE constraint is defined.

referenced

bit

When 1, the table referenced by the Table object used depends on the listed in the result set.

注释

When IncludeAll is TRUE, the result set enumerates all tables on which FOREIGN KEY constraints are defined. The value of the result set column referenced determines FOREIGN KEY dependency on the referenced table.

When IncludeAll is FALSE (default), the result set enumerates only those tables that contain FOREIGN KEY constraints that depend on the referenced table.
