SQL Server 2008，出席表

Question

我有3张桌子：

表员工：

EmpID | EmpName
1     |'Mr. A'
2     |'Mr. B'

Table OffDays：

OffDayID | OffDayName | OffDayValue
1        | 'Saturday' | 7
2        | 'Sunday'   | 1

表出席率：

AttendanceID | Date         | EmpID
1            | '2014-06-02' | 1
2            | '2014-06-03' | 1
3            | '2014-06-04' | 1
4            | '2014-06-05' | 1
5            | '2014-06-10' | 1

员工'先生'2014-06-06'周五和'2014-06-09'星期一没有'身份证1'。 如何正确查询以显示假期'0214-06-07'，周六和'2014-06-8'周日之间缺席。

请帮忙。

我的存储过程是

DECLARE @DATE_FROM AS DATETIME
DECLARE @DATE_TO AS DATETIME
SET @DATE_FROM = '2014-05-01'
SET @DATE_TO = '2014-05-31'

DECLARE @DATE_FROM2 AS DATETIME  
DECLARE @DATE_TO2 AS DATETIME  

SET @DATE_FROM2 = @DATE_FROM  
SET @DATE_TO2 = @DATE_TO  

TRUNCATE TABLE AttendanceRegister                      

--------------------Present,Absent,Leave-----------------------  
WHILE @DATE_FROM <= @DATE_TO
