Dim instance As Database
Dim value As Boolean
value = instance.ConcatenateNullYieldsNull
instance.ConcatenateNullYieldsNull = value

public:
virtual property bool ConcatenateNullYieldsNull {
bool get () sealed;
void set (bool value) sealed;
}
[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase|SfcPropertyFlags.Design)>]
abstract ConcatenateNullYieldsNull : bool with get, set
[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase|SfcPropertyFlags.Design)>]
override ConcatenateNullYieldsNull : bool with get, set
final function get ConcatenateNullYieldsNull () : boolean
final function set ConcatenateNullYieldsNull (value : boolean)
