Report Builder 3 - SQL subquery to get unique values.

Hi. I need some help with an sql query to get unique values.

Using the following sample data:

I need to be able to get one single value for feeBudRec returned for each feeRef. The value of each feeBudRec is always the same for each individual feeRef (eg for every data row feeRef LR01 will have a feeBudRec of 1177).

The reason why I need to get a single feeBudRec value for each feeRef is that I need to be able to total the feeBudRec value for each feeRef in a feePin (eg for feePin LEE, I need to total the feeBudRec values for LR01 and PS01, which should be 1177 + 1957 to get a total of 3134; but if I don't have unique values for feeBudRec, it will add the values for each row, which would bring back a total of 11756 for the 8 LEE rows).

My experience with writing SQL queries is limited, but from searching the internet, it looks like I'll need to put in a subquery into my SQL query in order to get a single unique feeBudRec figure for each feeRef, and that a subquery that gets a minimum feeBudRec value for each feeRef should work for me.

Based on examples I've found, I think the following subquery should work:

SELECT a.feeRef, a.feeBudRec
  FROM (
    SELECT uvw_EarnerInfo.feeRef, Min(uvw_EarnerInfo.feeBudRec) as AvailableTime
    FROM uvw_EarnerInfo
    GROUP BY
    uvw_EarnerInfo.feeRef
) as x INNER JOIN uvw_EarnerInfo as a ON a.feeRef = x.feeRef AND a.feeBudRec = x.AvailableTime;

The problem is that I have no idea how to insert that subquery into the query I'm using to produce the report (as follows):

SELECT
  uvw_EarnerInfo.feeRef
  ,uvw_EarnerInfo.PersonName
  ,uvw_EarnerInfo.PersonSurname
  ,uvw_EarnerInfo.feePin
  ,uvw_RB_TimeLedger.TimeDate
  ,uvw_RB_TimeLedger.matRef
  ,uvw_RB_TimeLedger.TimeTypeCode
  ,uvw_RB_TimeLedger.TimeCharge
  ,uvw_RB_TimeLedger.TimeElapsed
  ,uvw_WoffTimeByTime.WoffMins
  ,uvw_WoffTimeByTime.WoffCharge
  ,uvw_EarnerInfo.feeBudRec
  ,uvw_EarnerInfo.personOccupation
FROM
  uvw_RB_TimeLedger
  LEFT OUTER JOIN uvw_WoffTimeByTime
    ON uvw_RB_TimeLedger.TimeId = uvw_WoffTimeByTime.TimeId
  RIGHT OUTER JOIN uvw_EarnerInfo
    ON uvw_EarnerInfo.feeRef = uvw_RB_TimeLedger.feeRef
WHERE
  uvw_RB_TimeLedger.TimeDate >= @TimeDate
  AND uvw_RB_TimeLedger.TimeDate <= @TimeDate2

If that subquery will get the correct results, can anyone please help me with inserting it into my report query. Otherwise, can anyone let me know what I will need to do to get a unique feeBudRec value for each feeRef?
