属性值

类型：Microsoft.SqlServer.Management.Smo. . :: . .ForeignKeyAction
A ForeignKeyAction value that specifies the action taken when the row that is referenced by the foreign key is deleted.

注释

The DeleteAction property can be used to specify that the action is cascaded. This means that the foreign key row is also deleted. You can also set the foreign key to the default value, or set it to Null.
