RangeSum(Peek('QuestionNum'), 1), 1) as QuestionNum,
;

LOAD

Resident Questions;

FinalTable:
LOAD Distinct lender_offer_id
Resident Table;

FOR i = 1 to FieldValueCount('QuestionNum')

LET vField = FieldValue('QuestionNum', $(i));

Left Join (FinalTable)

Hello Mohammed Mukram,
While I'm trying load the data to my project I'm getting an error like "Field 'QuestionNum' not found"
Can u please help me in this??

Hi,

QuestionNum we are creating for just to hold the number of records in the tables.

Table:
LOAD lender_offer_id,question_text,answer_text,
If(lender_offer_id= Previous(lender_offer_id),
RangeSum(Peek('RecordNumber'), 1), 1) as RecordNumber
;

LOAD
question_text, answer_text,question_id,answer_id,lender_offer_id
Resident Questions;

FinalTable:
LOAD Distinct lender_offer_id
Resident Table;

FOR i = 1 to FieldValueCount('RecordNumber')

LET vField = FieldValue('RecordNumber', $(i));

Left Join (FinalTable)
LOAD lender_offer_id,
question_text as [Q$(vField)],
answer_text as [A$(vField)]
Resident Table
Where RecordNumber= $(vField);

NEXT i
DROP Table Table;

// can you try above script

I have seen in your script you loaded the table by using Resident table Question, have you dropped that table after resident load?

paste complete script here.

Hi Mohammed Mukram,
Thanks for clearing the doubt.....
Actually for each lender_offer_id there will be 10 questions and as well as the answers i.e Q1 to Q10 and A1 to A10
However Im getting only Q1,Q2,Q3 and A1,A2,A3......

Regards,

mdmukramali · ‎2019-02-07

Hi,

Well for that issue we need to check the data.
for that can you export the data into Excel or Qvd as share with us.

sunny_talwar · ‎2019-02-07

How about if you add an order by statement here

Table_Tmp:
LOAD lender_offer_id,
  question_text,
  answer_text,
  If(lender_offer_id = Previous(lender_offer_id), RangeSum(Peek('RecordNumber'), 1), 1) as RecordNumber;
LOAD question_text,
  answer_text,
  question_id,
  answer_id,
  lender_offer_id
Resident Questions
Order By lender_offer_id;
