EnumReferencedKeys Method

Esta característica se quitará en una versión futura de Microsoft SQL Server. Evite utilizar esta característica en nuevos trabajos de desarrollo y tenga previsto modificar las aplicaciones que actualmente la utilizan.

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

Sintaxis

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.

Notas

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.
