У меня есть триггер для аудита вставок, удалений и обновлений.Я изменил онлайн-скрипт для этого.Сценарии прекрасно работают без каких-либо модификаций, но для бизнес-требований я внес несколько изменений.Для 9 таблиц во всей моей базе данных этот триггер имеет пользовательские изменения.Триггер работает отлично для всех 8 таблиц, кроме 1. 1 таблица, для которой он вызывает проблемы, предназначена только для 1 столбца.
Моя таблица содержит следующие столбцы:
CREATE TABLE [d2c].[linkage_profile](
[linkage_profile_id] [int] IDENTITY(1,1) NOT NULL Primary Key,
[first_name] [nvarchar](250) NULL,
[last_name] [nvarchar](250) NULL,
[middle_name] [nvarchar](250) NULL,
[suffix] [nvarchar](50) NULL,
[is_pregnant] [bit] NULL,
[expected_date] [datetime2](7) NULL,
[user_id] [int] NOT NULL,
[is_grace_period] [bit] NOT NULL,
[closed_date] [datetime2](7) NULL,
[birth_gender_id] [int] NOT NULL,
[status_id] [int] NOT NULL,
[assigned_date] [datetime2](7) NULL,
[created_by] [nvarchar](50) NULL,
[date_created] [datetime2](7) NOT NULL,
[modified_by] [nvarchar](50) NULL,
[date_modified] [datetime2](7) NULL,
[state_no] [nvarchar](20) NULL,
[county_id] [int] NULL,
[area_name] [nvarchar](3) NULL,
[ehars_client_profile_id] [int] NULL,
[priority_id] [int] NULL,
[assigned_by] [nvarchar](50) NULL,
Это триггер, который я использую:

Когда я обновляю, вставляю или удаляю все столбцы, триггер обрабатывает все, кроме последнего столбца Assigned_by.Я не могу понять, в чем проблема.он не проходит через этот код
"if substring(COLUMNS_UPDATED(),@char, 1) & @bit > 0 or @Type in ('I','D')" which is at the very bottom. HELP!!!
