Question

我在SQL Server中编写了以下查询

（适用QUERY）

select ISNULL(count(WORKHOUR) ,'-') AS present, 
ISNULL((count(*)-count(WORKHOUR)),'-') AS absent,
ISNULL(cast(SUM(DateDiff(MINUTE,  CAST('0:00' as time), WORKHOUR))/60 as nvarchar(3)) + ':' + cast(SUM(DateDiff(MINUTE,  CAST('0:00' as time), WORKHOUR))%60 as nvarchar(2)),'-') AS TOTALWRKHRS,
ISNULL(cast(AVG(DateDiff(MINUTE,  CAST('0:00' as time), WORKHOUR))/60 as nvarchar(3)) + ':' + cast(AVG(DateDiff(MINUTE,  CAST('0:00' as time), WORKHOUR))%60 as nvarchar(2)),'-') AS AVGWRKHRS
from "+**currMonthVal**+" m,"+**currYearVal**+" e WHERE E.EMPID=M.EMPID AND E.LOCATION=M.LOCATION AND M.EMPID = ?
and DATENAME(WEEKDAY, attdate) not IN ('Saturday', 'Sunday') and CONVERT(VARCHAR(10),ATTDATE,3) not in ("+**resultantHL**+")

其中currMonthVal和currYearVal是从外部传递的月和年值，结果HL是holiday_dates（例如＆＃39; 24/12 / 2016＆＃39; 25/12 / 2016＆＃39;）外部。

此查询正常。

我有一个名为 WORKING_DAYS 的表格如下：＆＃39;

COLUMN_ID     COLUMN_NAME     DATA_TYPE
---------------------------------------
1                ID           NUMBER
2               WDATE         DATE
3             INSTITUTE_ID    NUMBER

表格中的样本数据是：

COLUMN_ID     WDATE     INSTITUTE_ID
---------------------------------------
1            05-12-15     1
2            19-11-16     1

表中的这两个日期实际上在相应月份被宣布为额外工作日，并在周六或周日宣布。

我的要求是：我在上面的查询中排除了所有星期六和星期日[使用DATENAME（WEEKDAY，attdate）而不是IN（＆＃39; Saturday＆＃39;，＆＃39; Sunday＆＃39;）]但我不想在WORKING_DAYS表中排除上述两个日期，但包括它们我希望在相同的查询中尽可能在WHERE子句中执行此操作。

我该怎么办？

注意： 我已经从WORKING_DAYS表中检索了额外的工作日并存储在字符串变量中，并希望在条件中传递该变量值

Answer 1

或者您的日期也在WORKING_DAYS就足够了：

替换

DATENAME(WEEKDAY, attdate) not IN ('Saturday', 'Sunday')

通过

(DATENAME(WEEKDAY, attdate) not IN ('Saturday', 'Sunday') or adddate in (select wdate from WORKING_DAYS))

除特定周末外，不包括周末
