Function/Proc

Question

Hi I have to automate the update. I have 3 possible variables, VariantIdIN , QuestionIdIn and third is the column name. In the following example column name will be ACS_Sufferer. What are my options to automated the process? I tried to write a function but I don't know how to take the column name as a variable and update it. Please help.
DECLARE
CURSOR pharm_cur
IS
SELECT ms.rtvmemberid,
ms.StartTime,
MAX(CASE WHEN v.variantid = VariantIdIN THEN 'Y' ELSE 'N' END)ACS_Sufferer
FROM rsch_membersurvey_T4 ms, rsch_response r, rsch_variant v
WHERE mr.rsch_membersurveyid = ms.rsch_membersurveyid
AND ms.responseid = r.responseid
AND ms.variantid = v.variantid(+
AND r.questionid = QuestionIdIn
GROUP BY ms.rtvmemberid, ms.StartTime, ms.UpdateDate
ORDER BY ms.rtvmemberid, ms.UpdateDate;
BEGIN     
FOR pharm_rec IN pharm_cur
     LOOP
UPDATE prf_pharmasufferer ps
SET ACS_SUFFERER = decode(ps.ACS_SUFFERER,'Y','Y',pharm_rec.ACS_SUFFERER)
WHERE ps.rtvmemberid=pharm_rec.rtvmemberid
END LOOP;
END;

try this declaration
CURSOR pharm_cur IS
SELECT ms.rtvmemberid[b] rtvmemberid, ms.StartTime StartTime, ms.UpdateDate UpdateDate,
MAX(CASE WHEN v.variantid =Variantid_IN THEN 'Y' ELSE 'N' END) Sufferer
FROM rsch_membersurvey_pharma2 ms, rsch_memberresponse_pharma2 mr, rsch_response r,
rsch_variant v, rsch_survey s
WHERE mr.rsch_membersurveyid = ms.rsch_membersurveyid AND mr.responseid = r.responseid
AND mr.variantid = v.variantid(+) AND ms.completedind = 'Y'
AND mr.surveyid = s.surveyid
AND s.surveytype = 'Pharma2'
AND r.questionid = QUESTIONID_IN
GROUP BY ms.rtvmemberid, ms.StartTime, ms.UpdateDate;
