Question

我正在进行数据提取，以获取有关员工的人口统计信息我遇到了失踪员工的问题，因为不是每个人都有电话号码（我不知道为什么）

现在我有重复项，因为有些人有主要和非主要的电话号码。
它们可以被列为移动，家庭，工作等...我想要的是如果员工有一个主要电话号码列出它，但如果他们根本没有号码，我希望它被列出as＆＃34; N / A＆＃34;。

以下是我的查询。我很感激任何帮助。

SELECT  DISTINCT
        EJC.PersonTaxIdNo AS [SSN]
        ,EJC.EmpNo AS [Employee ID]
        ,ISNULL(EJC.Salutation, 'N/A') AS [Salutation]
        ,LTRIM(EJC.FirstName) AS [First Name]
        ,LTRIM(EJC.LastName) AS [Last Name]
        ,ISNULL(EJC.NameSuffix,'N/A') AS [Suffix]
        ,VPA.PersonAddress1 AS [Address]
        ,ISNULL(VPA.PersonAddress2,'') AS [Address 2]
        ,VPA.PersonAddressCity AS [City]
        ,VPA.PersonAddressStateAbbrev AS [State]
        ,VPA.PersonAddressPostalCode AS [Zip]
        ,CASE WHEN VPH.PersonPhonePrimaryInd = 1 AND (GETDATE() BETWEEN     VPH.PersonPhoneFromEffectDate AND VPH.PersonPhoneToEffectDate) THEN     VPH.PersonPhoneNo
            WHEN VPH.PersonPhoneNo IS NULL THEN 'N/A' END AS     [Primary Phone]
FROM CNKronos.CNKronos.dbo.EmployeeJob_Curr EJC
    LEFT JOIN CNKronos.CNKronos.dbo.vPERSON_ADDRESSES VPA
        ON EJC.PersonIdNo = VPA.PersonIdNo
    LEFT JOIN CNKronos.CNKronos.dbo.vPERSON_PHONES VPH
        ON EJC.PersonIdNo = VPH.PersonIdNo
WHERE VPA.PersonAddressPrimaryInd = 1
    AND GETDATE() BETWEEN VPA.PersonAddressFromEffectDate AND     VPA.PersonAddressToEffectDate
ORDER BY LTRIM(EJC.LastName), LTRIM(EJC.FirstName)

很难给你一个没有架构的解决方案。
所以我会尝试教你如何使用CTE Common Table Expressions

SQL FIDDLE DEMO

在小提琴中，您只需选择WITH内的代码即可查看部分结果。

该查询可以获得该日期范围内的有效手机。 User1有数据User2不

with current_phone as (
   SELECT u.name, p.*
   FROM 
       users u 
   left join phone p 
       on u.user_id = p.user_id
       and GETDATE() BETWEEN FromDate and ToDate
)
SELECT name, CASE 
                 WHEN phone is null then 'NA'
                 ELSE phone
             END as phone
FROM current_phone

您的想法是在CTE中进行小型计算，然后将结果与主表连接。希望能帮助您找到解决方案。

您也可以使用更好的架构更新sqlFiddle并告诉我。
