EnumReferencedKeys Method

  • 發行項

未來的 Microsoft SQL Server 發行版本將不再提供此功能。請避免在新的開發工作中使用此功能，並計劃修改目前使用此功能的應用程式。

The EnumReferencedKeys method returns a QueryResults object that enumerates the PRIMARY KEY and UNIQUE constraints.

語法

object
.EnumReferencedKeys( [ ReferencedTable ] , [ IncludeAll ] )as QueryResults

Parts

  • object
    Expression that evaluates to an object in the Applies To list.
  • ReferencedTable
    Optional. String that names an existing Microsoft SQL Server table. Restricts result set membership to list only references to objects defined on the specified table.
  • IncludeAll
    TRUE or FALSE.

Prototype (C/C++)

HRESULT EnumReferencedKeys(
LPSQLDMOQUERYRESULTS* ppResults,
SQLDMO_LPCSTR ReferencedTableName = NULL,
BOOL IncludeAllCandidates = NULL);

Returns

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

Column Data type Description

candidate_key

nvarchar(129)

Name of a PRIMARY KEY or UNIQUE constraint.

candidate_table

nvarchar(262)

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

referenced

bit

When 1, the table depends on the PRIMARY KEY or UNIQUE constraint listed in the result set.

備註

When IncludeAll is TRUE, the result set enumerates all PRIMARY KEY and UNIQUE constraints defined in the database. The value of the result set column referenced determines table object dependency on the listed PRIMARY KEY or UNIQUE constraint.

When IncludeAll is FALSE (default), the result set enumerates only those PRIMARY KEY or UNIQUE constraints on which the table depends.
