Sql 删除后触发器未插入多行

看

DELETED

可以包含多行，因此请改用

SELECT

就你而言：

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

可以包含多行。因此，将列中的值指定给标量变量总是一个错误

请尝试：

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

有人一定会指出一些边缘情况，在触发器中使用这样的语句不是错误：

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

但是这样的情况是少数——我想不出有什么好的

您当前查询中的每个

SELECT

s都将从

deleted

的任意行中选择一个值-甚至不能保证每个

SELECT

s都将从同一任意行中获得一个值。

这是用于什么数据库系统的？触发器没有标准化，

sql

标记用于标准sql语言。另外，既然您已经编写了一个部分工作的触发器，那么代码在哪里？向我们展示您的触发器。：）如果你发布你当前的代码，我们也许可以修复它。什么样的行？网格行？HTML表格行？SQL行？@jlafay
