声明
<SfcObjectAttribute(SfcContainerRelationship.ChildContainer, SfcContainerCardinality.ZeroToAny,  _
    GetType(Check), SfcObjectFlags.Design)> _
Public ReadOnly Property Checks As CheckCollection 
    Get
用法
Dim instance As Table 
Dim value As CheckCollection 

value = instance.Checks

    typeof(Check), SfcObjectFlags.Design)]
public CheckCollection Checks { get; }

[SfcObjectAttribute(SfcContainerRelationship::ChildContainer, SfcContainerCardinality::ZeroToAny, 
    typeof(Check), SfcObjectFlags::Design)]
public:
property CheckCollection^ Checks {
    CheckCollection^ get ();
}

[<SfcObjectAttribute(SfcContainerRelationship.ChildContainer, SfcContainerCardinality.ZeroToAny, 
    typeof(Check), SfcObjectFlags.Design)>]
member Checks : CheckCollection

function get Checks () : CheckCollection

属性值

类型：Microsoft.SqlServer.Management.Smo.CheckCollection
A Check object that represents all the check constraints that are defined on the table.

示例

The following code example shows how to display the names of each check constraint on each AdventureWorks2012 table.

C#

Server srv = new Server("(local)");
Database db = srv.Databases["AdventureWorks2012"];

foreach (Table tb in db.Tables)
{
   foreach (Check ck in tb.Checks)
   {
      Console.WriteLine("The " + tb.Name + " table has the " + ck.ToString() + " check.");
   }
}

Powershell

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

Foreach ($tb in $db.Tables)
{
   Foreach ($ck in $tb.Checks)
   {
      Write-Host "The" $tb.Name "table has the" $ck "check."
   }
}
