SQL Query returning repeating information

Question

I'm having an issue where this query statement is giving me repeating GoalText in the results. Any ideas?

The complete query statement:

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));

Results:

The individual queries that make up the query:

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 

Results: There are 444 records in this query, but you should get the idea.

Answer 1

Re-wrote your query so it's more readable, and turns subquerys (yuck) into JOINs:

SELECT g.goaltext
       g.goalid, 
       gr.goalreqid
  FROM GOAL g
  JOIN GOALREQUIREMENT gr ON gr.goalid = g.goalid AND gr.reqbmilevel IS NULL AND gr.reqenergybalance IS NULL
  JOIN JOIN SURVEYANSWER sa ON sa.questionid = gr.questionid AND sa.surveyanswer = gr.reqquestionvalue AND sa.surveyanswer = 1
  JOIN QUESTION q ON q.questionid = gr.questionid
 WHERE sa.cycleid = 93

It's the goalid and/or goalreqid column(s) that causing the rows to come out duplicated. Because the goaltext column is associated to multiple goalid/etcs, you're never going to get single entries for goaltext while including goalids.

Answer 2

You're joining two tables together. Obviously, records in the first table match more than one record from the 2nd table. When that happens, the record from the first table is duplicated in the result set for every record in the 2nd table that it matches.

Answer 3

When a row in the first table joins to more than one row in the 2nd table, you apparently only want it to show once in the query output. In that case, WHICH row from the 2nd table do you want to show in this single output row??

• The row entered last?
• with biggest goalId?
• or whatever...

You need to answer this question before you can write a SQL query to do whatever your answer specifies..
