基本上我想为具有匹配activityid的所有行获取所有名称（RequiredAccount，RequiredContact，RequiredOwner）并将它们放在自己的列中。简而言之，我想获取多行数据并将它们放在一个列中。基本上我想做这个人正在做的事情（http://www.sqlprof.com/blogs/sqldev/archive/2008/03/31/how-to-list-multiple-rows-of-data-on-same -line.aspx）但我似乎无法让它发挥作用。
SELECT DISTINCT
Appointment.ActivityId, Appointment.ScheduledStart, Appointment.OwnerIdName, Contact.AccountIdName, Appointment.new_ContactPersonName,
Appointment.Subject, Appointment.new_ColderNotes, Account.AccountId, Contact_1.ContactId, SystemUser.SystemUserId, SystemUser.FullName AS OptionalOwner,
Contact_1.FullName AS OptionalContact, Account.Name AS OptionalAccount, ActivityParty.PartyId, ActivityParty.ParticipationTypeMask,
Contact_1.FullName AS RequiredContact, Account.Name AS RequiredAccount, SystemUser.FullName AS RequiredOwner, Account.new_BusinessUnit
FROM
Contact AS Contact_1 RIGHT OUTER JOIN
Account RIGHT OUTER JOIN
SystemUser RIGHT OUTER JOIN
Appointment INNER JOIN
ActivityParty ON Appointment.ActivityId = ActivityParty.ActivityId ON SystemUser.SystemUserId = ActivityParty.PartyId ON Account.AccountId = ActivityParty.PartyId ON
Contact_1.ContactId = ActivityParty.PartyId LEFT OUTER JOIN
Contact ON Appointment.new_ContactPerson = Contact.ContactId
如果ActivityID匹配，如果三个必需列位于一列中，我想要的是什么。所以前两行在新列中有两个名称。
任何想法，帮助等等。
非常感谢！
