SetIndexedColumnDESC 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 SetIndexedColumnDESC method specifies a column to sort in descending order as part of an index.
構文
object.SetIndexedColumnDESC(ColumnName ,Descending)
Parts
object
Expression that evaluates to an object in the Applies To list.ColumnName
String that specifies the column name.Descending
Boolean that specifies whether to sort a column in descending order.
Prototype (C/C++)
HRESULT SetIndexedColumnDESC(
SQLDMO_LPCSTR ColumnName,
BOOL NewValue);
説明
By default, columns in an index are sorted in ascending order. Use the ColumnName parameter to specify a column on which to perform a descending sort. Set the Descending parameter to TRUE to specify that the column must be sorted in descending order. You must call SetIndexedColumnDESC once for each column to be sorted in descending order as part of the index.
Prior to using SetIndexedColumnDESC, use the IndexedColumns property to define the list of columns participating in the index. SetIndexedColumnDESC can only be specified before an index is created and cannot be used on an existing index.
