In the following example, a runtime dynamic property called email is deleted from the Customer class.
vars
    cluster : JadeDynamicPropertyCluster;
begin
    cluster := Customer.findDynamicPropertyCluster("CustomerCluster");
    beginTransaction;
    cluster.deleteDynamicProperty("email");
    commitTransaction;
end;
        You could also code the previous example as follows.
begin
    beginTransaction;
    Customer.deleteDynamicProperty("email");
    commitTransaction;
end;
        You can delete a runtime dynamic property only if the class in which it is defined is not being used by any other process. If production mode is set, you can delete a runtime dynamic property in single user mode only.
