Creating and Update Statistics in Visual Basic

This code example creates a new table on an existing database for which the Statistic object and the StatisticColumn object are created.

'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")
'Reference the CreditCard table.
Dim tb As Table
tb = db.Tables("CreditCard", "Sales")
'Define a Statistic object by supplying the parent table and name arguments in the constructor.
Dim stat As Statistic
stat = New Statistic(tb, "Test_Statistics")
'Define a StatisticColumn object variable for the CardType column and add to the Statistic object variable.
Dim statcol As StatisticColumn
statcol = New StatisticColumn(stat, "CardType")
stat.StatisticColumns.Add(statcol)
'Create the statistic counter on the instance of SQL Server.
stat.Create()

Creating and Update Statistics in Visual C#

This code example creates a new table on an existing database for which the Statistic object and the StatisticColumn object are created.

{
            //Connect to the local, default instance of SQL Server.
            Server srv = new Server();
            //Reference the AdventureWorks2008R2 database. 
            Database db = default(Database);
            db = srv.Databases["AdventureWorks2008R2"];
            //Reference the CreditCard table. 
           
           Table tb = db.Tables["CreditCard", "Sales"];
            //Define a Statistic object by supplying the parent table and name 
            //arguments in the constructor. 
            Statistic stat = default(Statistic);
            stat = new Statistic(tb, "Test_Statistics");
            //Define a StatisticColumn object variable for the CardType column 
            //and add to the Statistic object variable. 
            StatisticColumn statcol = default(StatisticColumn);
            statcol = new StatisticColumn(stat, "CardType");
            stat.StatisticColumns.Add(statcol);
            //Create the statistic counter on the instance of SQL Server. 
            stat.Create();
        }

Creating and Update Statistics in PowerShell

This code example creates a new table on an existing database for which the Statistic object and the StatisticColumn object are created.

# Example of implementing a full text search on the default instance.
# Set the path context to the local, default instance of SQL Server and database tables

CD \sql\localhost\default\databases
$db = get-item AdventureWorks2008R2

CD AdventureWorks2008R2\tables

#Get a reference to the table
$tb = get-item Production.ProductCategory


# Define a FullTextCatalog object variable by specifying the parent database and name arguments in the constructor.

$ftc = New-Object -TypeName Microsoft.SqlServer.Management.SMO.FullTextCatalog -argumentlist $db, "Test_Catalog2"
$ftc.IsDefault = $true

# Create the Full Text Search catalog on the instance of SQL Server.
$ftc.Create()

# Define a FullTextIndex object variable by supplying the parent table argument in the constructor.
$fti = New-Object -TypeName Microsoft.SqlServer.Management.SMO.FullTextIndex -argumentlist $tb

#  Define a FullTextIndexColumn object variable by supplying the parent index 
#  and column name arguments in the constructor.

$ftic = New-Object -TypeName Microsoft.SqlServer.Management.SMO.FullTextIndexColumn -argumentlist $fti, "Name"

# Add the indexed column to the index.
$fti.IndexedColumns.Add($ftic)

# Set change tracking
$fti.ChangeTracking = [Microsoft.SqlServer.Management.SMO.ChangeTracking]::Automatic

# Specify the unique index on the table that is required by the Full Text Search index.
$fti.UniqueIndexName = "AK_ProductCategory_Name"

# Specify the catalog associated with the index.
$fti.CatalogName = "Test_Catalog2"

# Create the Full Text Search Index
$fti.Create()
