EnumSubscriptionViews2 Method
Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.
The EnumSubscriptionViews method returns a QueryResults object that enumerates subscription execution status information maintained at a Distributor.
Sintassi
object.EnumSubscriptionViews2( [ fExcludeAnonymous ] )as QueryResults
Parts
object
Expression that evaluates to an object in the Applies To list.fExcludeAnonymous
Boolean that specifies whether anonymous subscriptions views are enumerated. Default is FALSE.
Prototype (C/C++)
HRESULT EnumSubscriptionViews2(
LPSQLDMOQUERYRESULTS *ppResults,
BOOL fExcludeAnonymous) PURE;
Returns
When the DistributionPublication object references a merge replication publication, the QueryResults object that contains one result set is defined by these columns.

Osservazioni
The EnumSubscriptionViews2 method extends the functionality of the EnumSubscriptionViews method by including the optional fExcludeAnonymous parameter. When fExcludeAnonymous is set to TRUE, anonymous Distribution or Merge Agent views are not enumerated.
In the result set, date and time data returned in action_time and start_time is formatted as YYYYMMDD hh:mm:ss.fff.
Date part |
Description |
|---|---|
YYYY |
Represents the year in four digits. |
MM |
Represents the month in two digits (zero padded). |
DD |
Represents the day of the month in two digits (zero padded). |
hh |
Represents the hour using two digits, a twenty-four hour clock (zero padded). |
mm |
Represents the minute in two digits (zero padded). |
ss |
Represents the second in two digits (zero padded). |
fff |
Represents the fractional part of the second in three digits. |
For example, the value 20040512 18:12:00.000 is interpreted as 6:12 P.M., May 12, 2004.
[!NOTA]
If an application calls EnumSubscriptionViews2on an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
