运行以下查询 ORA-22992 时出现 oracle 异常：无法使用从远程表中选择的 LOB 定位器

        SELECT 
            OLU.CNIC,
            OLU.LR_USER_NAME NAME,
            OLU.FATHERS_NAME,
            OLU.ADDRESS,
            BATCH_VERIF.CREATED_DATE BATCH_DATE,
            TO_DATE(OLU.ATTRIBUTE9, 'mm/dd/yyyy hh:mi:ss AM')  TRANSLATION_DATE
    FROM ORION.ORN_LR_USER@LIV OLU
    INNER JOIN
    (
        SELECT MAX(BATCH_ID) BATCH_ID, CNIC
        FROM ORION.ORN_LR_BATCH_CNIC@LIV
        WHERE IMPORT_DATE IS NOT NULL AND IMPORTED = 'T'
        GROUP BY CNIC
    ) BATCH_CNIC
            ON (BATCH_CNIC.CNIC = OLU.CNIC
                    AND NVL (OLU.IS_BATCH_VERIFIED, 'F') = 'T' 
                    AND NVL (OLU.ATTRIBUTE10, 'F') = 'T'
                    AND OLU.ATTRIBUTE9 IS NOT NULL) 
        INNER JOIN ORION.ORN_FILE_BATCH_VERIF@LIV BATCH_VERIF
            ON BATCH_VERIF.BATCH_ID = BATCH_CNIC.BATCH_ID;

但是在评论 TRANSLATION_DATE 之后它工作正常，lob 类型的列也不是..可能是什么原因？

        SELECT 
            OLU.CNIC,
            OLU.LR_USER_NAME NAME,
            OLU.FATHERS_NAME,
            OLU.ADDRESS,
            BATCH_VERIF.CREATED_DATE BATCH_DATE
            --TO_DATE(OLU.ATTRIBUTE9, 'mm/dd/yyyy hh:mi:ss AM')  TRANSLATION_DATE
    FROM ORION.ORN_LR_USER@LIV OLU
    INNER JOIN
    (
        SELECT MAX(BATCH_ID) BATCH_ID, CNIC
        FROM ORION.ORN_LR_BATCH_CNIC@LIV
        WHERE IMPORT_DATE IS NOT NULL AND IMPORTED = 'T'
        GROUP BY CNIC
    ) BATCH_CNIC
            ON (BATCH_CNIC.CNIC = OLU.CNIC
                    AND NVL (OLU.IS_BATCH_VERIFIED, 'F') = 'T' 
                    AND NVL (OLU.ATTRIBUTE10, 'F') = 'T'
                    AND OLU.ATTRIBUTE9 IS NOT NULL) 
        INNER JOIN ORION.ORN_FILE_BATCH_VERIF@LIV BATCH_VERIF
            ON BATCH_VERIF.BATCH_ID = BATCH_CNIC.BATCH_ID;

“当我将此列转换为日期类型时出现问题”

嗯，听起来这可能是一个 Oracle 错误。但也许你可以用这个技巧来解决它：

TO_DATE(substr(OLU.ATTRIBUTE9, 1, 22), 'mm/dd/yyyy hh:mi:ss AM') TRANSLATION_DATE
