Sql server SQL Server 2008-在不带透视的列中显示行项目

我有三张桌子：房客、室友和个人记录

模式如下所示：

Table: Tenant
HMYPERSON   SCODE   sFirstName sLastName
        1   t0011   fName       lName

Table: room
HMYPERSON   HMYTENANT   sRelationShip
    9458            1   Roommate
    1024            1   Other
    1025            1   Roommate
    1026            1   Guarantor

Table: Person
HMY     UCODE   ULASTNAME   sFIRSTNAME      iPersonType
9458    r0011   roommate1   roommate1Fname  93
1024    r0012   roommate2   roommate2Fname  93
1025    r0013   roommate3   roommate3Fname  93
1026    r0014   roommate4   roommate4Fname  90

租户表包含租户记录。 房间的桌子上有记录。 PERSON表包含所有类型的人（租户、室友、供应商等）

HMYTENANT in ROOM table是租户表（HMYPERSON）的外键

HMYPERSON in ROOM table是PERSON table（HMY）的外键

PERSON表中的IPERSONTYPE指定它是什么类型的PERSON记录。（93是室友，90是担保人）

我想在一行中显示所有房客及其室友的姓名。 所有室友应显示在同一行和单独的列中。 （每个室友一列）

我写了一个查询，给出了我的室友名单，但是是成排的

以下是我写的：

Select t.scode, t.sLastname + ' ' + t.sFIRSTNAME TenantName, p.ULASTNAME + ' ' + p.sFIRSTNAME RoommateName
from tenant t
join room r on r.hmytenant = t.hmyperson
left join person p on p.hmy = r.hmyperson and (r.sRelationship <> 'Guarantor' or p.IPERSONTYPE<>90)
where t.hmyperson=1

但我想要的是：

scode     Tenantname     Roommate1     Roommate2     Roommate3

最多5个室友就足够了

谢谢你的帮助。

你能试试这个吗

WITH A AS (SELECT HMYPERSON, HMYTENANT, SRELATIONSHIP, P.ULASTNAME, p.SFIRSTNAME, ROW_NUMBER() OVER (PARTITION BY HMYTENANT ORDER BY HMYPERSON) AS RN
            FROM ROOM R
            INNER JOIN PERSON P ON P.HMY = R.HMYPERSON  
                                AND (R.SRELATIONSHIP <> 'Guarantor' OR P.IPERSONTYPE<>90)           
            )
SELECT T.SCODE, T.SLASTNAME + ' ' + T.SFIRSTNAME TENANTNAME
        , A1.ULASTNAME + ' ' + A1.SFIRSTNAME ROOMMATENAME_1
        , A2.ULASTNAME + ' ' + A2.SFIRSTNAME ROOMMATENAME_2
        , A3.ULASTNAME + ' ' + A3.SFIRSTNAME ROOMMATENAME_3
        , A4.ULASTNAME + ' ' + A4.SFIRSTNAME ROOMMATENAME_4

LEFT JOIN A A1 ON A1.HMYTENANT = T.HMYPERSON AND A1.RN=1

LEFT JOIN A A5 ON A5.HMYTENANT = T.HMYPERSON AND A5.RN=5
WHERE T.HMYPERSON=1

见：
