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。新規の開発作業ではこの機能を使用しないようにし、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ことを検討してください。
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

Prototype (C/C++)
HRESULT CheckAllocations(SQLDMO_LPBSTR pResult,
SQLDMO_DBCC_REPAIR_TYPE lType = SQLDMORepair_None);

|---|
| 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. |
Settings
| Constant | Value | Description |
|---|---|---|
SQLDMORepair_Allow_/DataLoss |
3 |
Attempt all database repairs regardless of the possibility of data loss. For example, delete corrupted text objects. |
SQLDMORepair_Fast |
1 |
Attempt database repair tasks that do not incur data loss. |
SQLDMORepair_None |
0 |
Default. Do not attempt database repair on database inconsistencies encountered. |
SQLDMORepair_Rebuild |
2 |
Attempt database repair tasks that do not incur data loss. Rebuild indexes on successful database repair. |
Returns
A string that contains error detail information.
解説
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.
