文章目录

1、本文主要说明在.Net Core（Demo为.Net5）中使用开源组件SqlTableDependency来监听ms sqlserver的数据库数据变化

2、github地址：https://github.com/IsNemoEqualTrue/monitor-table-change-with-sqltabledependency

3、安装nuget包：install-package SqlTableDependency

4、准备数据库脚本

sql 复制代码 
-- 新建表
create table UserInfoForTestSqlTableDependency(
    Id int not null primary key identity(1,1),
    Name varchar(50) not null,
    NickName varchar(50) not null,
    Sex int not null,
    Birthday datetime not null,
    Status int not null,
    CreateTime datetime not null,
    LastModifyTime datetime not null
)

-- 插入数据：测试SqlTableDependency
insert into UserInfoForTestSqlTableDependency(Name,NickName,Sex,Birthday,Status,CreateTime,LastModifyTime)
values('用户-测试SqlTableDependency','昵称-测试SqlTableDependency',1,'1996-02-27',1,getdate(),getdate())

-- 插入数据：测试SqlTableDependency
insert into UserInfoForTestSqlTableDependency(Name,NickName,Sex,Birthday,Status,CreateTime,LastModifyTime)
values('用户1-测试SqlTableDependency','昵称1-测试SqlTableDependency',2,'1995-11-21',1,getdate(),getdate())

-- 更新单条数据：测试SqlTableDependency
update UserInfoForTestSqlTableDependency set
Name = '修改用户-测试SqlTableDependency',
NickName = '修改用户昵称-测试SqlTableDependency',
Status = 1, -- 该字段未变化，更新为原始值，测试是否会通知
LastModifyTime = getdate()
where Id = 1

-- 更新多条数据：测试SqlTableDependency（会收到多条通知）
update UserInfoForTestSqlTableDependency set
LastModifyTime = getdate()

-- 删除数据：测试SqlTableDependency
delete from UserInfoForTestSqlTableDependency where Id = 1

-- 查询数据
select * from UserInfoForTestSqlTableDependency

5、相关代码（所有注释说明在代码中都有）
