Question

我不明白这个查询有什么问题。有人可以向我解释错误在哪里。太感谢了

SELECT
  WF1.GUID,
  WF1.COD_FONTE,
  WF1.NOME_FILE,
  VW.COD_STEP_PRECEDENTE,
  VW.COD_STEP_ATTUALE AS WF1
FROM
  MONITOR.FILE_WORKFLOW
  INNER JOIN MONITOR.VW_JOB_FONTE_STEP AS VW ON WF1.COD_FONTE = VW.COD_FONTE
  AND VW.JOB_KEY = 'FLATTENER'
WHERE
  WF1.GUID = '5f58d00b6102ab20a8d5c83f'
  AND WF1.ESITO = 'OK'
  AND WF1.COD_STEP = VW.COD_STEP_PRECEDENTE
  AND NOT EXISTS (
    SELECT
      1
    FROM
      MONITOR.FILE_WORKFLOW AS WF2
    WHERE
      WF2.GUID = '5f58d00b6102ab20'
      AND WF2.ESITO = 'OK'
      AND WF2.COD_STEP = VW.COD_STEP_ATTUALE
      AND WF1.IDE_FILE_WORKFLOW_PARENT = WF2.IDE_FILE_WORKFLOW_PARENT
  )

Answer 1

我确定您使用的表别名错误

VW.COD_STEP_ATTUALE AS WF1 <-- WF1 is a column alias 
FROM
MONITOR.FILE_WORKFLOW
                                              
INNER JOIN MONITOR.VW_JOB_FONTE_STEP AS VW 
  ON WF1.COD_FONTE = VW.COD_FONTE <-- here you are using WF1 as a table alias

我认为这将解决问题

VW.COD_STEP_ATTUALE
FROM
MONITOR.FILE_WORKFLOW WF1 <-- alias name goes here
