DataFile 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 DataFile property specifies the operating system name of the primary file implementing the referenced Microsoft SQL Server replication distribution database.

语法

object.DataFile [=value]

Parts

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

  • value
    A string that identifies an operating system file by name

Data Type

String

Modifiable

Read/write if the DistributionDatabase object is used to create a replication distribution database. Read-only if a DistributionDatabase object references an existing SQL Server database.

Prototype (C/C++)

HRESULT GetDataFile(SQLDMO_LPBSTR pRetVal);
HRESULT SetDataFile(SQLDMO_LPCSTR NewValue);
注意注意

SQL Distributed Management Objects (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.

注释

Data storage for a SQL Server database is implemented in one or more operating system files. One operating system file maintains database-specific system table data and is identified as the primary database file.

When using the DistributionDatabase object to create a replication distribution database, fully specify an operating system file by setting the DataFolder and DataFile properties.
