CheckAllocations Method

この機能は、将来のバージョンの Microsoft SQL Server では削除される予定です。新しい開発作業では、この機能の使用を避け、現在この機能を使用しているアプリケーションは修正するようにしてください。

The CheckAllocations method scans all pages of the referenced database on Microsoft SQL Server 2000 and later, testing pages to ensure integrity.

構文

object.CheckAllocations( [ RepairType ] )as String

Parts

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

  • RepairType
    Optional. A long integer that specifies database repair action as described in Settings.

Prototype (C/C++)

HRESULT CheckAllocations(SQLDMO_LPBSTR pResult,
SQLDMO_DBCC_REPAIR_TYPE lType = SQLDMORepair_None);
注意注

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.

説明

The database referenced by the SQL-DMO object must be in single-user mode when using the RepairType argument of the CheckAllocations method to perform database repair. To set single-user mode on a database using SQL-DMO, use the SingleUser property of the DBOption object.

The CheckAllocations method is implemented using the Transact-SQL DBCC CHECKALLOC statement. The return value of CheckAllocations is a string representation of the error messages returned by DBCC CHECKALLOC.
