Type Property (Index)
Dieses Feature wird in einer zukünftigen Version von Microsoft SQL Server entfernt. Verwenden Sie dieses Feature beim Entwickeln neuer Anwendungen nicht, und planen Sie das Ändern von Anwendungen, in denen es zurzeit verwendet wird.
The Type property exposes configured attributes of the referenced Microsoft SQL Server component.
Syntax

.Type [= value]
Parts
- object
An expression that evaluates to an object in the Applies To list.
- value
A long integer that specifies index attributes as described in Settings.
Data Type
Long, enumerated
Modifiable
Read/write when using the Index object to define a SQL Server index. Read-only when the Index object references an existing SQL Server index.
Prototype (C/C++)
HRESULT GetType(SQLDMO_INDEX_TYPE* pRetVal)
HRESULT SetType(SQLDMO_INDEX_TYPE NewValue)
Settings
| Constant | Value | Description |
|---|---|---|
SQLDMOIndex_Clustered |
16 |
The index is clustered. SQL Server supports a single clustered index on any table. |
SQLDMOIndex_Default |
0 |
The index is nonclustered. |
SQLDMOIndex_DRIIndex |
6144 |
The index is used to maintain a declarative referential constraint. |
SQLDMOIndex_DRIPrimaryKey |
2048 |
The index implements a SQL Server PRIMARY KEY constraint. A value is returned only. For more information, see Key Object. |
SQLDMOIndex_DRIUniqueKey |
4096 |
The index implements a UNIQUE constraint on a table not constrained by primary key. The index is a candidate key. |
SQLDMOIndex_DropExist |
32768 |
Optimizes index creation when an existing index is rebuilt. |
SQLDMOIndex_Hypothetical |
32 |
Redirects index creation, mapping Index object manipulation to CREATE STATISTICS and DROP STATISTICS statements. |
SQLDMOIndex_IgnoreDupKey |
1 |
Controls error generation when an INSERT or UPDATE operation could cause a constraint violation and the index implements a PRIMARY KEY or UNIQUE constraint. |
SQLDMOIndex_NoRecompute |
16777216 |
Creates index with statistics computation off. For more information, see NoRecompute Property. |
SQLDMOIndex_PadIndex |
256 |
Index nodes are padded using a fill factor. |

Obsolete. |
SQLDMOIndex_/SortedDataReorg |
8192 |

SQLDMOIndex_Unique |
2 |
The index implements a UNIQUE constraint. |
SQLDMOIndex_Valid |
41747 |
