将多个电子邮件地址透视到列

Question

我需要旋转电子邮件表，以便不同的电子邮件地址显示在不同的列中。数据相对简单。对于以下令人困惑的代码，我得到以下错误消息。第6行，关键字“ FROM”附近的语法不正确。第14行，关键字“ AS”附近的语法不正确。感谢您对高级的所有帮助！我是一个相对新手：）

我需要将电子邮件放在不同的列中

``  
      SELECT Emails.entity_FK,
             CASE WHEN emails.MyDefault = 1 THEN emails.EmailAddress END AS EmailPrimary,
             CASE WHEN em.RowNum = 1 THEN em.EmailAddress END AS Email_2,
             CASE WHEN em.RowNum = 2 THEN em.EmailAddress END AS Email_3,
             CASE WHEN em.RowNum = 3 THEN em.EmailAddress END AS Email_4,

       FROM Emails
            LEFT JOIN
            (
            SELECT Entity_FK, EmailAddress,  
            ROW_NUMBER() OVER (PARTITION BY Entity_FK ORDER BY Email_PK) 
               as RowNum

            )  AS em
             emails.Entity_FK = em.Entity_FK
            WHERE emails.EntityTypeCode_FK = 126
