我有一个“DaysUntilDue”列，说明何时需要完成文档。我需要使用“记录日”列根据“到期日”计算“到期日”，并排除周六和周日。

我所拥有的只是我知道我需要工作的列。我有来自排除 Sat 和 Sun 的 Case When 语句的代码，但不知道如何将其合并到我需要做的事情中。我有我需要的所有列，并且都以它们需要的方式链接。真的很挣扎如何发表声明说使用现有的“DaysUntilDue”从文档的“logTime”计算截止日期，但不包括周末

SELECT     
CategoryName, 
DocCategory,
DaysUntilDue, 
TranNbr, 
DueDate, 
LogTime
FROM Queue INNER JOIN WQMTransactions ON Queue.TranNbr = WQMTransactions.TranNbr INNER  JOIN 
 ServiceQ INNER JOIN CategoryList ON ServiceQn.TranID =      CategoryList.TranID 
 INNER JOIN Category ON CategoryList.CategoryID =     Category.CategoryID 
 ON Queue.CategoryID = Category.CategoryID AND Queue.TranID = ServiceQ.TranID

也许是因为睡眠不足，但从概念上讲，我无法确定该怎么做。

我假设我需要使用我为另一个 qry 做类似事情而构建的这个案例陈述。

CASE WHEN Doc IN ( 'POS', 'Card' )
     THEN CAST(DATEADD(d, CASE DATEPART(dw, DateEntered)
                            WHEN 7 THEN 2
                            WHEN 1 THEN 1
                            ELSE 0
                          END, DateEntered) + ( DATEPART(dw,
                                                      DATEADD(d,
                                                      CASE DATEPART(dw,
                                                      DateEntered)
                                                      WHEN 7 THEN 2

我试图更正您的查询。还计算了DueDate。当 DaysUntilDue = 0 时，DueDate 为空。

SELECT     
CategoryName, 
DocCategory,
DaysUntilDue, 
TranNbr, 
LogTime,
dateadd(day, a.n, LoggedDay) DueDate
FROM Queue 
INNER JOIN WQMTransactions ON Queue.TranNbr = WQMTransactions.TranNbr 
INNER JOIN ServiceQ ON Queue.CategoryID = Category.CategoryID AND Queue.TranID = ServiceQ.TranID
INNER JOIN CategoryList ON ServiceQn.TranID = CategoryList.TranID 
INNER JOIN Category ON CategoryList.CategoryID = Category.CategoryID 
cross apply
(
select coalesce(max(number)+1, 0) n
from(
select top (DaysUntilDue) number from 
master..spt_values
WHERE TYPE = 'P'
and datediff(day, -number-1, LoggedDay) % 7 not in (5,6)
order by number
) 
a)
