UpdateStatistics Method

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 UpdateStatistics method forces data distribution statistics update for a referenced Microsoft SQL Server index or all indexes defined on a SQL Server table.

語法

object
.UpdateStatistics(
)

Parts

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

Prototype (C/C++)

HRESULT UpdateStatistics( );

備註

Index-based, data distribution statistics support SQL Server query optimization. Data distribution statistics are calculated for an index when the index is first used in query optimization or at user direction. Statistics are updated automatically at configurable intervals and at user direction.

Applies To:

Index Object

Table Object
