ValidateSubscriptions 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 ValidateSubscriptions method invokes inline validation for one or more specified subscriptions.
Sintassi
object.ValidateSubscriptions(szSubscriberNames,szSubscriberDBs,
[ ValidationOption ] , [ ValidationMethod ] , [ fShutDownAgent ] )
Parts
object
Expression that evaluates to an object in the Applies To list.szSubscriberNames
SQL Distributed Management Objects (SQL-DMO) multistring that specifies one or more Subscriber names.szSubscriberDBs
SQL-DMO multistring that specifies one or more subscription database names.ValidationOption
Long integer that specifies the type of validation performed as described in Settings.ValidationMethod
Long integer that specifies the method of validation performed as described in Settings.fShutDownAgent
Boolean that specifies whether the distribution agent immediately shuts down after successful completion of the validation process.
Prototype (C/C++)
HRESULT ValidateSubscriptions(
SQLDMO_LPCSTR szSuscriberNames,
SQLDMO_LPCSTR szSubscriberDBs,
SQLDMO_VALIDATIONOPTION_TYPE ValidationOption,
SQLDMO_VALIDATIONMETHOD_TYPE ValidationMethod,
BOOL fShutDownAgent);
Settings
Set the ValidationOption parameter using these SQLDMO_VALIDATIONOPTION_TYPE values.
Constant |
Value |
Description |
|---|---|---|
SQLDMOValidationOption_/70Checksum |
0 |
Perform a SQL Server 7.0 compatible Transact-SQL CHECKSUM operation. |
SQLDMOValidationOption_/RowCountOnly |
1 |
(Default). Perform a Transact-SQL @@ROWCOUNT operation. |
SQLDMOValidationOption_/75Checksum |
2 |
Perform a SQL Server 2000 compatible Transact-SQL CHECKSUM operation. |
Set the ValidationMethod parameter using these SQLDMO_VALIDATIONMETHOD_TYPE values.
Constant |
Value |
Description |
|---|---|---|
SQLDMOValidationMethod_/ConditionalFast |
2 |
Default. Performs conditional validation first using SQLDMOValidationMethod_FastCount but reverts to using SQLDMOValidationMethod_FullCount if SQLDMOValidationMethod_FastCount indicates differences. |
SQLDMOValidationMethod_/FastCount |
1 |
Performs high speed validation, using the rowcnt column of sysindexes. |
SQLDMOValidationMethod_/FullCount |
0 |
Validates by returning the number of rows, including NULL values, and duplicates using Transact-SQL COUNT(*). |
Osservazioni
szSuscriberNames and szSubscriberDBs are SQL-DMO multistring parameters. The number of names in the szSuscriberNames and szSubscriberDBs parameters must be identical. For more information about setting multistring parameters, see Using SQL-DMO Multistrings.
The result of the validation operation is written to the agent history, which can be viewed using Replication Monitor.
By default, the fShutDownAgent parameter is set to FALSE.
[!NOTA]
If an application calls ValidateSubscriptionson 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.
