Script Method (Replication Objects)

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 Script method generates a Transact-SQL command batch that can be used to re-create the Microsoft SQL Server component referenced by the SQL Distributed Management Objects (SQL-DMO) object.

Sintassi

object.Script( [ ScriptType ] , [ ScriptFilePath ] )as String

Parts

  • object
    Expression that evaluates to an object in the Applies To list.

  • ScriptType
    Optional. A long integer that overrides default scripting behavior as described in Settings.

  • ScriptFilePath
    Optional. A string that specifies an operating system file as an additional target for the generated Transact-SQL statements script.

Prototype (C/C++)

HRESULT Script(
SQLDMO_REPSCRIPT_TYPE ScriptType = SQLDMORepScript_Default,
SQLDMO_LPCSTR ScriptFilePath = NULL,
SQLDMO_LPBSTR ScriptText = NULL);

(Distributor Object)

HRESULT Script(
SQLDMO_REPSCRIPT_TYPE ScriptType = SQLDMORepScript_InstallDistributor,
SQLDMO_LPCSTR ScriptFilePath = NULL,
SQLDMO_LPBSTR ScriptText = NULL);

[!NOTA]

SQL-DMO strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString.

Settings

When setting the ScriptType argument specifying multiple behaviors, combine values using an OR logical operator. Use these SQLDMO_REPSCRIPT_TYPE values to set ScriptType.

SQLDMORepScript_/ReplicationJobs

4194304

Script creation of replication-related jobs to preserve job schedule and steps. The corresponding job script must be run before the replication script. This constant can only be used with Microsoft SQL Server. Only a member of the sysadmin fixed server role or the owner of a job have access to a job creation script.

SQLDMORepScript_/SubscriptionCreation

Obsolete.

SQLDMORepScript_/SubscriptionDeletion

524288

Obsolete.

SQLDMORepScript_/ToFileOnly

Output generated by an executed script is directed to an operating system file only. If not set, output is available as status or error messages.

SQLDMORepScript_/UnicodeFile

33554432

Output to a file is written as Unicode character text.

SQLDMORepScript_/UninstallDistributor

512

Script removes the replication Distributor.

SQLDMORepScript_/UninstallPublisher

2048

Script removes a Publisher.

SQLDMORepScript_/UninstallReplication

2097152

Script removes replication.

Returns

A Transact-SQL command batch as a string.

Osservazioni

The Script method of replication objects captures an image of a SQL Server replication installation. For example, using the Script method of the TransArticle object generates a command batch that can be used to create the transactional or snapshot replication article referenced, not the object replicated by the article.

To script the creation of a single pull subscription, call the Script method using SQLDMORepScript_PullSubscriptionCreation on a TransPullSubscription or MergePullSubscription object. To script the removal of a single pull subscription, call the Script method using SQLDMORepScript_PullSubscriptionDeletion on a TransPullSubscription or MergePullSubscription object.

To script the creation of pull subscriptions in the TransPullSubscriptions or MergePullSubscriptions collection, call the Script method using SQLDMORepScript_PullSubscriptionCreation. To script the removal of pull subscriptions from the TransPullSubscriptions or MergePullSubscriptions collection, call the Script method using SQLDMORepScript_PullSubscriptionDeletion.

To script the creation of or dropping pull subscriptions in a database, call the Script method using SQLDMORepScript_PullSubscriptionCreation on a ReplicationDatabase object. To script the removal of pull subscriptions from a database, call the Script method using SQLDMORepScript_PullSubscriptionDeletion on a ReplicationDatabase object.

To script the creation of pull subscriptions on a server, call the Script method using SQLDMORepScript_PullSubscriptionCreation on a ReplicationDatabases collection or Subscriber object. To script the removal of pull subscriptions from a server, call the Script method using SQLDMORepScript_PullSubscriptionDeletion on a ReplicationDatabases collection or Subscriber object.

For SQL-DMO objects publish database objects, SQL-DMO implements the ScriptDestinationObject method to generate command batches that re-create the objects published. For more information, see ScriptDestinationObject Method.

[!NOTA]

SQL-DMO object scripting methods are fully compatible with an instance of SQL Server version 7.0. However, database compatibility level affects Transact-SQL command batch contents.

When scripting a database with a compatibility level of less than 7.0, or when scripting any of its objects, the resulting Transact-SQL command batch includes only keywords reserved by that level.

Transact-SQL command syntax is always compliant with an instance of SQL Server 7.0. Where provided, you can use optional scripting arguments, such as SQLDMOScript2_NoFG to remove some syntax of an instance of SQL Server 7.0.
