EnumReferencedTables Method

  • 项目

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 EnumReferencedTables method returns a QueryResults object that enumerates tables on which a PRIMARY KEY or UNIQUE constraint is defined.

语法

object
.EnumReferencedTables( [ IncludeAll ] ) as QueryResults

Parts

  • object
    Expression that evaluates to an object in the Applies To list
  • IncludeAll
    TRUE or FALSE

Prototype (C/C++)

HRESULT EnumReferencedTables(
LPSQLDMOQUERYRESULTS* ppResults,
BOOL IncludeAllCandidates = NULL);

Returns

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 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.

备注

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.
