Question

我在SQL中创建了一个游标。我想要的是，

首先获得当天日期后6个月的员工卡，
然后我得到该雇员的统计
然后我通过一些计算来计算工作天数的数量。

为此，光标如下所示

IF(@Type = 'C') 
    BEGIN
            Print 'Yes I am in the Current process';        
        DECLARE daily_Allocate CURSOR FOR  
                Select distinct c.emp_card_no, c.emp_name, c.Dt_Of_Join from emp_mst c  
                    join emp_mon_day d 
                    on c.emp_card_no=d.emp_mkey 
                    WHERE Dt_Of_Join =  CAST(FLOOR(CAST( DATEADD(month, -6, GETDATE()) AS FLOAT ))AS DATETIME)  
            OPEN daily_Allocate   
            FETCH NEXT FROM daily_Allocate INTO
            @emp_card_no, @emp_name, @Dt_Of_Join
            WHILE @@FETCH_STATUS = 0   
            BEGIN   
                    select  @Total_days = Sum(total_day),@Days_worked = Sum(days_worked)
                    from emp_mon_day a      
                    where  a.emp_mkey = @emp_card_no
                    group by emp_mkey       

                        PRINT 'Employee Card no ' + cast(@emp_card_no as char)      --Working
                        PRINT 'Total days ' + cast(@Total_days as char)             --Working
                        PRINT 'Days Worked ' +  cast(@Days_worked as char)          --Working

                set @Final_PaidDayLop = 0;
                declare @TotalRecord as varchar(155)
                set @TotalRecord = 0;

                Select @Final_PaidDayLop = sum(days)       
                    from  P_Emp_Del_App_Hdr c join P_Emp_Del_App_trl d on c.mkey=d.mkey       
                    where c.delete_flag='N' and app_flag='Y' and c.year = @actualYear
                and c.emp_mkey = @emp_card_no

                PRINT 'Final Paid LOP '  + cast(@Final_PaidDayLop as char)         -- Not working

            Select @TotalRecord =  ((1.75 * 6) / @Total_days) * (@Days_worked + @Final_PaidDayLop) 
                from emp_mon_day a where  a.emp_mkey = @emp_card_no group by emp_mkey   

            PRINT 'Total Record ' + cast(@TotalRecord as char)                     -- Not working

                  FETCH NEXT FROM daily_Allocate INTO 
                  @emp_card_no, @emp_name, @Dt_Of_Join 
            END   
        CLOSE daily_Allocate   
        DEALLOCATE daily_Allocate
END

在那个游标中，我通过PRINTING它的值测试数据，但是对于某些打印它不起作用。

详情如下：

NOT PRINTING LINE

PRINT 'Final Paid LOP '  + cast(@Final_PaidDayLop as char)

和

PRINT 'Total Record ' + cast(@TotalRecord as char)

打印线

PRINT 'Employee Card no ' + cast(@emp_card_no as char)
                        PRINT 'Total days ' + cast(@Total_days as char)
                        PRINT 'Days Worked ' +  cast(@Days_worked as char)

我很困惑为什么有些人没有打印出来。任何帮助将不胜感激。

我正在使用SQL Server 2008

将@Final_PaidDayLop的选择替换为：

           Select @Final_PaidDayLop = coalesce(sum(days),0)      
                from  P_Emp_Del_App_Hdr c join P_Emp_Del_App_trl d on c.mkey=d.mkey       
                where c.delete_flag='N' and app_flag='Y' and c.year = @actualYear
            and c.emp_mkey = @emp_card_no

SQL游标有些打印不起作用
