Question

我正在尝试从5个不同的表中提取信息的选择查询，并且我在from部分中遇到错误。我已经尝试了几种代码变体，但没有任何工作。下面是代码和错误。

SELECT incident.incidentowner, 
       incident.qualitymember, 
       incident.purchasingmember, 
       incident.additionalmember, 
       incident.customername, 
       incident.customercontact,
       incident.incidentid, 
       incident.stockcode, 
       incident.incidentdate,
       incident.stocksupplier,
       incident.customeraccountno,
       incident.supplydate,
       incident.incidentsite,
       incident.depot, 
       incident.samplesent,
       incident.quantity, 
       incident.incidentvalue, 
       incident.branchtransfer,
       incident.hireorsale,
       incident.quarantined,
       incident.returnedtosupplier,
       incident.replacedbysupplier,
       incident.creditedbysupplier,
       incident.incidentdescription,
       containment.containment,
       containment.containmentdate,
       rootcause.rootcause,
       rootcause.rootcausedate,
       correctiveaction.correctiveaction,
       correctiveaction.correctiveactiondate,
       validation.validation,
       validation.director,
       validation.validationdate 
FROM Incident 
INNER JOIN containment ON 
      incident.incidentid = containment.incidentid
INNER JOIN rootcause ON
      incident.incidentid = rootcause.incidentid
INNER JOIN correctiveaction ON
      incident.incidentid = correctiveaction.incidentid
INNER JOIN validation ON
      incident.incidentid = validation.incidentid
WHERE Incident.IncidentID = @incidentid

这会返回以下错误

 Additional information: Syntax error (missing operator) in query expression
'incident.incidentid = containment.incidentid INNER JOIN rootcause ON
 incident.incidentid = rootcause.incidentid INNER JOIN correctiveaction ON 
 incident.incidentid = correctiveaction.incidentid INNER JOIN validation ON       
 incident.incidentid = validation.inci'.

需要额外的parantheses，谢谢微软

FROM (((Incident 
INNER JOIN containment ON 
  incident.incidentid = containment.incidentid)
INNER JOIN rootcause ON
  incident.incidentid = rootcause.incidentid)
INNER JOIN correctiveaction ON
  incident.incidentid = correctiveaction.incidentid)
INNER JOIN validation ON
  incident.incidentid = validation.incidentid

多个内部联接错误
