sql-server - グループ反復で最初の行が欠落している CTE 連結

Question

複数行の値を単一の行に連結しようとしています...近接を達成しましたが、以下のクエリでは毎回最初の行が欠落していることに気付きました...ここで明らかな何かが欠けていますか? これまで CTE を使用したことがないので、その背後にある概念を理解しようと懸命に努力しています。前もって感謝します。

WITH CTE ( AnswerResponseRefId, QuestionComponentList, QuestionComponentName, 
     templevel )
        AS ( 
            SELECT
            tao1.AnswerResponseRefId,
            CAST( '' AS VARCHAR(MAX) ) AS QuestionComponentList, 
            CAST( '' AS VARCHAR(69) )  AS QuestionComponentName, 
            0 AS templevel
            FROM
            TargetAnswersOrdered tao1
            WHERE tao1.QuestionRefId = 'B6944310-96FA-401C-86FE-A7BEA1D7B2B0'
            and tao1.TargetRefId = '5E013FC7-5AC9-45E4-A4D7-000F3C241599'
            GROUP BY tao1.AnswerResponseRefId

        UNION ALL

            SELECT          
                qc.AnswerResponseRefId,
                CAST( c.QuestionComponentList + 
                 CAST(c.QuestionComponentName AS VARCHAR(64)) AS VARCHAR(MAX) ),
                CAST( qc.QuestionComponentRefId AS VARCHAR(64)) + '*V' + 
                 CAST( qc.QuestionComponentVersion AS VARCHAR(2)) + '*',
                templevel + 1
            FROM CTE c

            INNER JOIN 

            TargetAnswersOrdered qc
            ON 
                c.AnswerResponseRefId = qc.AnswerResponseRefId 
            WHERE 
                CAST( qc.QuestionComponentRefId AS VARCHAR(64)) + '*V' + 
                CAST( qc.QuestionComponentVersion AS VARCHAR(2)) + '*' 
                    > c.QuestionComponentName
        )

SELECT 
    AnswerResponseRefId, 
    QuestionComponentList
FROM ( SELECT   
            AnswerResponseRefId, 
            QuestionComponentList, 
            RANK() OVER ( PARTITION BY 
                            AnswerResponseRefId 
                            ORDER BY templevel DESC )FROM CTE ) 
D ( AnswerResponseRefId, QuestionComponentList, rank )
    WHERE rank = 1 ;

解決済み..

間違った参照を使用しています

CAST( c.QuestionComponentList + CAST( qc.QuestionComponentRefId AS VARCHAR(64)) + ' V' + CAST( qc.QuestionComponentVersion AS VARCHAR(2)) + ' ' AS VARCHAR(MAX) ) AS QuestionComponentList,
