用法
Dim instance As DatabaseDdlTrigger
Dim value As Boolean

value = instance.AnsiNullsStatus

instance.AnsiNullsStatus = value

[SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase)]
public bool AnsiNullsStatus { get; set; }

[SfcPropertyAttribute(SfcPropertyFlags::None|SfcPropertyFlags::Standalone|SfcPropertyFlags::SqlAzureDatabase)]
public:
property bool AnsiNullsStatus {
    bool get ();
    void set (bool value);
}

[<SfcPropertyAttribute(SfcPropertyFlags.None|SfcPropertyFlags.Standalone|SfcPropertyFlags.SqlAzureDatabase)>]
member AnsiNullsStatus : bool with get, set

function get AnsiNullsStatus () : boolean
function set AnsiNullsStatus (value : boolean)

属性值

类型：System. . :: . .Boolean
A Boolean value that specifies whether ISO NULL handling is enabled in the DDL trigger. ISO NULL handling requires that any comparison to a NULL value equates to a NULL value.
If True, ISO NULL handling is enabled and comparisons to null values equate to False.
If False (default), ISO NULL handling is disabled and comparisons to null values equate to True.

注释

This property specifies whether any comparison to a null value equates to a NULL value. For example, A SELECT statement using WHERE column_name <> NULL returns zero rows even if there are nonnull values in column_name.
