Answer 1

См. CREATE TRIGGER.

CREATE TRIGGER TRIG_SomeTable_Delete 
    ON SomeTable AFTER DELETE 
    AS 
     BEGIN 
      INSERT INTO SomeTable(SomeColumn) 
      SELECT SomeColumn FROM DELETED 
     END 

DELETED может содержать несколько строк, поэтому использовать SELECT вместо этого.

В вашем случае:

ALTER TRIGGER [tgr_del_into_plan_audit] 
    ON [dbo].[agent_plan_details] 
    AFTER DELETE 
    AS 
     BEGIN 
      SET NOCOUNT ON; 
      INSERT INTO agent_plan_details_audit 
      (
       plan_title_id, 
       plan_title, 
       no_of_property_listing, 
       validity_of_plan, 
       Each_property_listing_life, 
       list_of_property_in_search_result, 
       price, 
       discount, 
       discount_code, 
       discount_percentage, 
       create_date, 
       action 
      ) 
      SELECT 
       plan_title_id, 
       plan_title, 
       no_of_property_listing, 
       validity_of_plan, 
       Each_property_listing_life, 
       list_of_property_in_search_result, 
       price, 
       discount, 
       discount_code, 
       discount_percentage, 
       GETDATE(), 
       'D' 
      FROM DELETED 
     END 

Answer 2

deleted может содержать множественные строки. Таким образом, присвоение значений из столбцов в нем скалярной переменной равно .

Try, вместо:

ALTER 
TRIGGER [tgr_del_into_plan_audit] 
ON [dbo].[agent_plan_details] 
AFTER DELETE 
AS 

SET NOCOUNT ON 

INSERT INTO agent_plan_details_audit 
(plan_title_id, 
    plan_title, 
    no_of_property_listing, 
    validity_of_plan, 
    Each_property_listing_life, 
    list_of_property_in_search_result, 
    price, 
    discount, 
    discount_code, 
    discount_percentage, 
    create_date, 
    action) 
SELECT 
    plan_title_id, 
    plan_title, 
    no_of_property_listing, 
    validity_of_plan, 
    Each_property_listing_life, 
    list_of_property_in_search_result, 
    price, 
    discount, 
    discount_code, 
    discount_percentage, 
    GETDATE(), 
    'D' 
FROM 
    deleted

Кто-то обязан указать некоторый край случай, когда он не ошибка иметь такое заявление в качестве триггера:

select @plan_title_id=d.plan_title_id from deleted d; 

Но такие обстоятельства, безусловно, y - Я не могу думать ни о чем с головы.

Каждые из этих SELECT с в текущем запросе будет выбрать значение из произвольной строки deleted - это даже не гарантируется, что каждые из SELECT с бы получить значение из же произвольной строки.
