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.

只有 Microsoft .NET Framework 2.0 版支援此命名空間、類別或成員。

範例

'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()
