PrimaryFile Property

后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The PrimaryFile property identifies the operating system file that maintains database-specific system tables.

语法

object
.PrimaryFile [= value]

Parts

• object
  An expression that evaluates to an object in the Applies To list

• value
  TRUE or FALSE

备注

A Microsoft SQL Server database can have, at most, one primary file. When a database is created using SQL Distributed Management Objects (SQL-DMO), the first DBFile object named PRIMARY added to the DBFiles collection of the FileGroup object referencing the filegroup becomes the primary file. Set the PrimaryFile property to alter the default behavior.

Data Type

Boolean

Modifiable

Read/write prior to database creation. Read-only after database creation.

Prototype (C/C++)

HRESULT GetPrimaryFile(LPBOOL pRetVal);
HRESULT SetPrimaryFile(BOOL NewValue);

备注

Running Transact-SQL scripts before an initial snapshot is applied can be used to:

• Perform presnapshot cleanup.
• Add users and permissions to databases to be replicated.
• Create user-defined data types.

  注意：
  If PreSnapshotScript is set, the script automatically runs when a subscription is reinitialized. Therefore, the script must be written so that its statements are repeatable.
