この質問が以前に何度も出されたことは知っていますが、ここでこれに関するすべての議論を見てきましたが、私の問題を解決するのに役立つものはありませんでした.

だから私の問題は、このエラーが発生したことです。私が理解していることから、このエラーは列がどのテーブルからデータを取得するかを判断できなかったため、 s.sampleid などの列名変数をssampleid として指定することで解決できます。右？

これが私のコードです

select * from(select S.S_SAMPLEID,s.collectiondt,SDI.PARAMLISTID||'|'||SDI.PARAMID as paramlistparam,s.u_samcondition,SDI.enteredtext,sdi.displayunits As Unit, sd.s_datasetstatus
case when SDIS.condition = 'Pass' then 'Pass'
when SDIS.condition = 'Fail' then 'Fail'
when SDIS.condition = 'Warning' then 'Warning'
when SDIS.waivedflag = 'Y' then 'Waived'
else 'No Spec' end as quality
from s_sample s left join sdidata sd on s.s_sampleid=sd.keyid1 AND SD.SDCID = 'Sample'
LEFT JOIN SDIDATAITEM SDI ON sd.keyid1 = SDI.KEYID1 AND SDI.SDCID = 'Sample' AND SD.PARAMLISTVERSIONID = SDI.PARAMLISTVERSIONID AND SD.VARIANTID = SDI.VARIANTID AND SD.DATASET = SDI.DATASET AND SD.PARAMLISTID = SDI.PARAMLISTID
LEFT JOIN SDIDATAITEMSPEC SDIS ON SDI.KEYID1 = SDIS.KEYID1 AND SDI.PARAMLISTVERSIONID = SDIS.PARAMLISTVERSIONID AND SDI.VARIANTID = SDIS.VARIANTID AND SDI.DATASET = SDIS.DATASET AND SDI.PARAMLISTID = SDIS.PARAMLISTID  AND SDI.PARAMID = SDIS.PARAMID AND SDI.PARAMTYPE = SDIS.PARAMTYPE AND SDIS.SDCID = 'Sample'
where s.samplepointid='"+samplepoint+"' and sdi.paramlistid in ('"+paramlistid+"') and sdi.paramid in ('"+paramid+"') and s.collectiondt between '"+startdt+"' and '"+enddt+"' and sd.s_datasetstatus in ('"+statussql+"') and SDIS.condition in ('"+qualitysql+"'))
pivot(max(enteredtext) as result, max(Unit) as unit for  paramlistparam in ('"+paramlistpa+"')) order by collectiondt

そして、列に変数を与えることで私がしたことは次のとおりです

select * from(select s.S_SAMPLEID as ssampleid,s.collectiondt,SDI.PARAMLISTID||'|'||SDI.PARAMID as paramlistparam,s.u_samcondition as scondition,SDI.enteredtext as sdienteredtext,SDI.displayunits As Unit, sd.s_datasetstatus as sddataset
case when SDIS.condition = 'Pass' then 'Pass'
when SDIS.condition = 'Fail' then 'Fail'
when SDIS.condition = 'Warning' then 'Warning'
when SDIS.waivedflag = 'Y' then 'Waived'
else 'No Spec' end as quality
from s_sample s left join sdidata sd on s.s_sampleid=sd.keyid1 AND SD.SDCID = 'Sample'
LEFT JOIN SDIDATAITEM SDI ON sd.keyid1 = SDI.KEYID1 AND SDI.SDCID = 'Sample' AND SD.PARAMLISTVERSIONID = SDI.PARAMLISTVERSIONID AND SD.VARIANTID = SDI.VARIANTID AND SD.DATASET = SDI.DATASET AND SD.PARAMLISTID = SDI.PARAMLISTID
LEFT JOIN SDIDATAITEMSPEC SDIS ON SDI.KEYID1 = SDIS.KEYID1 AND SDI.PARAMLISTVERSIONID = SDIS.PARAMLISTVERSIONID AND SDI.VARIANTID = SDIS.VARIANTID AND SDI.DATASET = SDIS.DATASET AND SDI.PARAMLISTID = SDIS.PARAMLISTID  AND SDI.PARAMID = SDIS.PARAMID AND SDI.PARAMTYPE = SDIS.PARAMTYPE AND SDIS.SDCID = 'Sample'
where s.samplepointid='"+samplepoint+"' and sdi.paramlistid in ('"+paramlistid+"') and sdi.paramid in ('"+paramid+"') and s.collectiondt between '"+startdt+"' and '"+enddt+"' and sd.s_datasetstatus in ('"+statussql+"') and SDIS.condition in ('"+qualitysql+"')
or s.samplepointid='"+samplepoint+"' and sdi.paramlistid in ('"+paramlistid+"') and sdi.paramid in ('"+paramid+"') and s.collectiondt between '"+startdt+"' and '"+enddt+"' and sd.s_datasetstatus in ('"+statussql+"') and SDIS.condition is null)
pivot(max(sdienteredtext) as result, max(Unit) as unit for  paramlistparam in ('"+paramlistpa+"')) order by collectiondt

私がテストしたところ、エラーはparamlistpaによって引き起こされました
