Count Property

未來的 Microsoft SQL Server 版本將移除這項功能。請避免在新的開發工作中使用這項功能，並規劃修改目前使用這項功能的應用程式。

The CountProperty indicates the number of items in a list or collection.

語法

object.Count [=value]

Parts

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

  • value
    A long value that specifies the number of items in a list or collection.

Data Type

Long

Modifiable

Read-only

Prototype (C/C++)

HRESULT GetCount(LPLONG plConnectionID);

備註

The Count property is modified when items are added or removed from a collection or list, or when the Refresh method retrieves new values from an instance of Microsoft SQL Server. The property always reflects the number of items currently in the collection or list.

Applies To:

All collections and lists.
