SQL Query返回重复信息

Question

我有一个问题,这个查询语句让我在结果中重复使用GoalText.有任何想法吗？

完整的查询语句:

Select  g.GoalText, convert(nvarchar, g.GoalID) + '|' + convert(nvarchar, r.GoalReqID) as GoalID, GoalReqID
from Goal g inner join GoalRequirement r
on g.GoalID = r.GoalID 
where GoalReqID in
  (Select GoalReqID
  from GoalRequirement r inner join SurveyAnswer a
   on r.QuestionID = a.QuestionID and  ReqQuestionValue = SurveyAnswer 
   where a.CycleID = 93 and ReqBMILevel is null
  and ReqEnergyBalance is null and SurveyAnswer = 1 and r.QuestionID in
    (Select  QuestionID from Question where QuestionParent = 6000));

结果:

GoalText   GoalID  GoalReqID
