Because the tables in a database are accessed in a variety of queries, the distribution of data within a table can affect how successful an index is. By updating the index statistics, the most efficient way of accessing the data will be selected.

仅 Microsoft .NET Framework 的 2.0 版本支持此命名空间、类或成员。

示例

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks database.
Dim db As Database
db = srv.Databases("AdventureWorks")

'Update the index statistics on the database.
db.UpdateIndexStatistics()
