ALTER PROCEDURE [dbo].[PROC_UpdMonthStatus]

        declare order_cursor cursor

         --开始循环游标变量--
        fetch next from order_cursor into @Id,@Area,@Department,@Year,@Month
        while @@FETCH_STATUS = 0    --返回被 FETCH语句执行的最后游标的状态--
            begin
                ---添加一天办理记录            
                DECLARE @CreatorId varchar(36)
                SET @CreatorId=(select TOP 1 CreatorId from AuditOptions where AreaMonthReportId=@Id order by CreateTime desc)
                insert into AuditOptions(ID,Link,CreateUser,CreatorId,OptionText,CreateTime,AreaMonthReportId)
                values (NEWID(),‘总部审核‘,@CreatorId,‘‘,‘自动同意‘,GETDATE(),@Id)
                --修改ProjectMonthTrack
                update ProjectMonthTrack set ProjectStatus=5 where [email protected] and [email protected] and [email protected] and ReportMonth=@Month
                --修改AreaMonthReport
                update AreaMonthReport set Status=5 where Id=@Id
                
                
                set @[email protected]+1
                set @error= @error + @@ERROR   --记录每次运行sql后是否正确，0正确
                fetch next from order_cursor into @Id,@Area,@Department,@Year,@Month   --转到下一个游标，没有会死循环
            end    
    END
GO

以上代码主要实现了一条添加，以及2条修改记录
