How to loop over query data and insert in structure?

Question

I have query data that should be inserted in the structure. While looping over data each value should be assigned to matching column. Here is example of query data:

    REC_ID  NAME    STATUS      TYPE    YEAR
1   01      PARIS   Approved    1       2019
2   06      AUSTIN  Inactive    3       2017
3   48      LONDON  Approved    2       2018
4   43      ROME    Inactive    5       2019
5   61      DUBLIN  Inactive    4       2019

This data should be organized to look like this:

1
  REC_ID  01
  NAME    PARIS
  STATUS  Approved
  TYPE    1
  YEAR    2019
2
  REC_ID  06
  NAME    AUSTIN
  STATUS  Inactive
  TYPE    3
  YEAR    2017
3
  REC_ID  48
  NAME    LONDON
  STATUS  Approved
  TYPE    2
  YEAR    2018
4
  REC_ID  43
  NAME    ROME
  STATUS  Inactive
  TYPE    5
  YEAR    2019
5
  REC_ID  61
  NAME    DUBLIN
  STATUS  Inactive
  TYPE    4
  YEAR    2019

I tried to get desired data format with this function:

function formatData(qryData) {
    local.fnResult = structNew();
    local.fnData = structNew();

    if(qryData.recordcount){
        for(row in qryData) {
            for(column in qryData.columnList) {
                local.strRec = structNew();
                structInsert(strRec, column, row[column]);
                local.fnData[qryData.currentrow] = strRec;
            }
        }
    }

    writeDump(fnData);
}

Here is how my result looks:

1
  REC_ID  01
2
  REC_ID  06
3
  REC_ID  48
4
  REC_ID  43
5
  REC_ID  61

I use ColdFusion 11 cfscript syntax. If anyone can help me solve this problem please let me know. Thank you.

There is an issue with your column list loop, you are creating a new structure for each column and that get reset in the next loop.

This loop should be changed

for(column in qryData.columnList) {
    local.strRec = structNew();
    structInsert(strRec, column, row[column]);
    local.fnData[qryData.currentrow] = strRec;
}

to look like

local.strRec = structNew();
for(column in qryData.columnList) {
    structInsert(strRec, column, row[column]);
}
local.fnData[qryData.currentrow] = strRec;
