使用触发器更新SQL表

Question

我正在用列表

[ID] [bigint] IDENTITY(1,1) NOT NULL,
[CompanyID] [bigint] NULL,
[EmployeeName] [nvarchar](50) NULL,
[EmployeeGSM] [nvarchar](50) NULL,
[EmployeeNumberOfDaysOfAnnualLeaveInEachMonth] [decimal](5, 2) NULL,
[EmployeeTotalNumberOfAnnualLeave] [decimal](7, 2) NOT NULL

在每个月的第一天00:00:00，我需要使用触发器将EmployeeTotalNumberOfAnnualLeave增量更新为EmployeeNumberOfDaysOfAnnualLeaveInEachMonth值

带着敬意

Answer 1

假设SQL应该是UPDATE Table SET EmployeeTotalNumberOfAnnualLeave = EmployeeTotalNumberOfAnnualLeave + EmployeeNumberOfDaysOfAnnualLeaveInEachMonth

你可以：

1）创建一个存储过程来执行任务：

CREATE PROCEDURE UpdateEmployeeTotalNumberOfAnnualLeave
AS
BEGIN
    UPDATE Table 
    SET EmployeeTotalNumberOfAnnualLeave = EmployeeTotalNumberOfAnnualLeave + EmployeeNumberOfDaysOfAnnualLeaveInEachMonth
END

2）创建计划的作业：

1）展开Sql Server代理

2）右键单击作业->新作业

3）给它起个名字

4）转到步骤->新建->设置它以执行您的过程

5）时间表->新增->将其设置为在每月的第一天执行

6）启用工作
