Use GROUP BY instead of DISTINCT. For example, if you want a distinct record for every combination of sID and sCode:

SELECT sCode,sDetail,pCost,pDiscount,sID,oMID;
  FROM stockPurchase;
  WHERE sID= ?lsID AND oMID = ?loMID;
  GROUP BY sID, sCode;
  ORDER BY sCODE

Since this will give you an error message in newer versions of VFP, you either have to change SET ENGINEBEHAVIOR, or use summary functions for every field not included in the GROUP BY clause, for example:

select sCode, max(sDetail), min(pCost), max(pDiscount), sID...;
  ...;
  group by sID, sCode
