EnumReferencedKeys Method

Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa caratteristica in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

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

Sintassi

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.

Osservazioni

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.
