Notes

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

Exemples

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

'Reference the AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")

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

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2012")

$db.UpdateIndexStatistics()
