Access SQL 中的 IIF 函数

Question

我正在尝试编写 IIF 语句以返回我的查询中的某些职位。

但是，当我去运行我的代码时，这个列甚至没有在我创建的表中返回。我在网上看了，似乎这是正确的语法。我是否遗漏了导致它不返回此列的内容？

IIF ([w.Job_Title] = "Sales Pro" OR [w.Job_Title] = "Services Pro" OR [w.Job_Title] = "Universal Pro" OR [w.Job_Title] = "Fulfillment Pro", "JobTitle", NULL),

我原来在查询的末尾有一个 WHERE 语句，但这似乎导致我的其他数据不准确，所以我认为这种 IIF 方式会更好。

以下是完整查询：

SELECT cal.FiscalYear,
       cal.FiscalQuarter,
       cal.FiscalMonth,
       cal.FiscalWeekNumber,
       Format(w.Day, "Dddd") AS DayOfWeek,
       cal.Day AS CalendarDay,
       w.Day,
       c.SegStart,
       c.SPLITNAME AS SkillName,
       w.Site,
       w.Campaign,
       w.Manager,
       w.Supervisor,
       IIF ([w.Job_Title] = "Sales Pro"
            OR [w.Job_Title] = "Services Pro"
            OR [w.Job_Title] = "Universal Pro"
            OR [w.Job_Title] = "Fulfillment Pro", "JobTitle", NULL),
       w.EmployeeNumber AS SalesID,
       w.ACDID,
       c.CallID,
       w.Employee,
       c.Caller_Name AS cms_EmployeeName,
       c.Answerer_Name AS cms_ProEmployeeName,
       c.Answered,
       c.AcwTime,
       c.Agt_Released AS AgentReleased,
       c.AnsHoldTime,
       c.AnsLogin,
       c.Calling_Pty AS CallingParty,
       c.Conference,
       c.ConsultTime,
       c.Dialed_Num AS DialedNumber,
       c.DispIVector,
       c.DispSplit,
       c.DispVDN,
       c.Duration,
       c.Disposition,
       c.Held,
       c.HoldABN AS AbanOnHold,
       c.OrigLogin,
       c.QueueTime,
       c.RingTime,
       c.TalkTime,
       c.Transferred,
       c.VDN2,
       c.VDN3,
       c.VDN4,
       c.VDN5
FROM (t_wfm AS w
      INNER JOIN t_cms AS c ON (c.CALLING_PTY = w.ACDID)
        AND (Format(c.SEGSTART, "Short date") = Format(w.[Day], "Short date")))
INNER JOIN tbl_Calendar AS cal ON cal.Day = w.Day;

您尚未提供列别名。

该列很可能在那里，但标题类似于Expr1 或其他内容。

我认为您想要的是检索实际标题，而不是常量"JobTitle"：

   IIF ([w.Job_Title] = "Sales Pro"
        OR [w.Job_Title] = "Services Pro"
        OR [w.Job_Title] = "Universal Pro"
        OR [w.Job_Title] = "Fulfillment Pro", [w.Job_Title], NULL) AS JobTitle,

编辑

如果您只想返回包含这些标题的行，则检查将进入 WHERE 子句。则不需要IIf()。

WHERE ([w.Job_Title] = "Sales Pro"
        OR [w.Job_Title] = "Services Pro"
        OR [w.Job_Title] = "Universal Pro"
        OR [w.Job_Title] = "Fulfillment Pro")
