Question

最近我遇到了一个非常奇怪的问题（Oracle 12c），LISTAGG适用于第一个别名列但不适用于第二个（两者几乎完全相同）抛出ORA-00904：“PARAMDESC”：无效的标识符。这是SQL：

 SELECT s_sample.s_sampleid,
   b.u_tarolotnumber,
   p.productdesc,
   s_sample.productid,
   LISTAGG(wi.s_departmentid, '; ') WITHIN
   GROUP(ORDER BY wi.s_departmentid) Department, 
   wi.workitemid, 
   s_sample.sampletypeid, 
   NVL((SELECT sa.aliasid 
          FROM sdialias sa
         WHERE sa.sdcid = 'Workitem'
           AND sa.keyid1 = wi.workitemid), wi.workitemdesc)workitemdesc, 
   NVL((SELECT sa.aliasid
          FROM sdialias sa
         WHERE sa.sdcid = 'ParamList' 
           AND sa.keyid1 = p.paramlistid), p.paramlistdesc) paramdesc

 FROM s_sample
 JOIN s_batch b ON s_sample.batchid = b.s_batchid
            AND s_sample.classification = 'ReagentQuality'
 JOIN s_product p ON s_sample.productid = p.s_productid
 JOIN sdiworkitem sdi ON sdi.keyid1 = s_sample.s_sampleid
                  AND sdi.sdcid = 'Sample'
 JOIN workitem wi ON wi.workitemid = sdi.workitemid
              AND wi.workitemversionid = sdi.workitemversionid
 JOIN sdiworkitemitem sdiwi ON wi.workitemid = sdiwi.workitemid
                        AND sdiwi.keyid1 = s_sample.s_sampleid
                        AND sdiwi.sdcid = 'Sample'
 JOIN paramlist p ON p.paramlistid = sdiwi.itemkeyid1
              AND p.paramlistversionid = sdiwi.itemkeyid2
              AND p.variantid = sdiwi.itemkeyid3
 WHERE s_sample.s_sampleid IN ('S100')
 AND 1 = 1
 GROUP BY s_sample.s_sampleid,
      b. u_tarolotnumber,
      p.productdesc,
      s_sample.productid,
      s_sample.sampletypeid,
      wi.workitemid,
      workitemdesc,          
      paramdesc;

很多谷歌搜索，但没有运气！任何帮助都将受到高度赞赏。

第一个别名作品第二个不会抛出无效的标识符
