您在第一个子查询中使用列别名犯了错误。在连接表时也使用表别名，它将具有更好的可读性和易用性。

您可以在第一个子查询中使用out别名检索列名，稍后可以在外部SELECT中添加别名。

您可以尝试以下查询：

SELECT X.CreationDate AS 'Date Created', X.PrintJobName AS 'Batch Id', X.JobId AS 'Job Name', X.JobToJobId AS 'Sub- Job Name', 
       X.DespatchMethod AS 'Postal Class', X.EnvelopeCode AS 'Envelope Code', 
       Y.[PrintStatus], Y.[PrintDate], Y.[DespatchDate], Y.[EnclosedDate], Y.[DocsetCount], Y.[FileName]
FROM (
    SELECT [CJ].CreationDate, [CJC].PrintJobName, [CJ].JobId, [CJJ].JobToJobId, [CJC].DespatchMethod, [CJC].EnvelopeCode
    FROM CORE.Jobs [CJ]
    INNER JOIN CORE.JobControlSheets [CJC] ON [CJ].JobId = [CJC].JobId
    LEFT OUTER JOIN CORE.JobToJob [CJJ] ON [CJ].JobId = [CJJ].SourceJobId
    ) AS X
INNER JOIN (
    SELECT [PrintStatus], [PrintDate], [DespatchDate], [EnclosedDate], [DocsetCount], [FileName]
    FROM (
        SELECT DISTINCT Jc.JobID, CASE 
                WHEN EXISTS (
                        SELECT DISTINCT jobid
                        FROM [MI_ProdMI].dbo.JOB_Tbl_000_Outstanding JO
                        WHERE JO.jobid = Jc.JobID
                        )
                    THEN 'Inprogress'
                ELSE 'Complte'
                END AS [PrintStatus], Jb.[FileName] AS [FileName]
        FROM [MI_ProdMI].dbo.JOB_Tbl_002_Completions Jc
        INNER JOIN [MI_ProdMI].dbo.JOB_Tbl_001_Jobs Jb ON Jb.ID = Jc.JobID
        ) AS A
    LEFT JOIN (
        SELECT JobID, [Timestamp] AS [PrintDate]
        FROM [MI_ProdMI].dbo.JOB_Tbl_002_Completions jc
        WHERE [Service] = 'PRINT'
            AND JobStatus = 'Printed'
        ) AS B ON A.JobID = B.JobID
    LEFT JOIN (
        SELECT jobid, sum(Packs) AS [DocsetCount], max(DespTimestamp) AS [DespatchDate]
        FROM [MI_ProdMI].dbo.JOB_Tbl_002_Completions
        GROUP BY JobID
        ) AS C ON B.JobID = C.JobID
    LEFT JOIN (
        SELECT JobID, TIMESTAMP AS [EnclosedDate]
        FROM [MI_ProdMI].dbo.JOB_Tbl_002_Completions
        WHERE JobStatus = 'Processed'
        ) D ON C.JobID = D.JobID
    ) AS Y ON Y.FileName = X.FileName

消息207，级别16，状态1，行3无效的列名称“CORE”
