SQLSERVER 存储过程及触发器

最近遇到一个业务。客户要求维护一个请假表，包含员工信息，请假信息！每年1月1日需要给员工增加新一年的年假，但3月才清除去年未修的年假！每次员工请假审批成功后需要同步更新假期表。

增加年假

USE [FE_APP5]
GO

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Annual_leave]') AND type in (N'P', N'PC'))
	DROP PROCEDURE [dbo].[Annual_leave]
GO

USE [FE_APP5]
GO

/****** Object:  StoredProcedure [dbo].[Annual_leave]    Script Date: 11/07/2017 18:10:29 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO


create procedure [dbo].[Annual_leave]

as
	declare @FN01 varchar(20)	-- 员工号
	declare @FN07 int -- 剩余年假
	declare @FN05 int -- 年假天数
	declare @FN04 date -- 入职时间
	declare @day int = 5 -- 默认年假天数
	declare @currentyear int
	declare @year int

	declare my_cur cursor for select FN01,FN05,FN07,FN04 from FT_1_49E74BA98FF7886574E1
	
	open my_cur
	
	fetch next from my_cur into @FN01,@FN05,@FN07,@FN04
	
	while @@FETCH_STATUS = 0
	begin
		
		--print @FN01
		--print @FN05
		--print @FN07
		
		 -- 当年假期计算规则
		if MONTH(@FN04) < 7 
			set @currentyear = YEAR(getdate()) - YEAR(@FN04) + @day
		else if MONTH(@FN04) >= 7
			set @currentyear = YEAR(getdate()) - YEAR(@FN04) + @day - 1
			
		print @currentyear
		
		if @currentyear > 12
			set @currentyear = 12
		set @year = @currentyear + @FN07 -- 当前总年假
		--print @year
		
		UPDATE FT_1_49E74BA98FF7886574E1 SET FN05 = @year,FN07 = @year,FN06 = 0,FN08 = @FN07 where FN01 = @FN01;
		fetch next from my_cur into @FN01,@FN05,@FN07,@FN04
	end
	close my_cur
	deallocate my_cur


--select * from FT_1_49E74BA98FF7886574E1

--exec Annual_leave
GO

以上使用了游标！
