code to unpack query array to tab-delimited data?

[sltfn]

Hello. I am very new to and still much in the dark about arrays. I am looking for efficient code to unpack the output from a query to lines of tab-delimited data (one record per line). Here is the code I've come up with so far. I'd guess there MUST be a more efficient approach.

on mouseup
## query constructed above
 put cdb_batchQuery(tInputA,"cloud","logicalAND","recordData") into tOutputA
 put flattenArray( tOutputA) into flattened -- see flattenArray function below
end mouseup

function flattenArray A , d1, d2, T,  X
   if T is empty then
      if d1 is empty then put cr into d1
      if d2 is empty then put tab into d2
   end if
   if A is not an array then return T  & X & A & d1
   repeat for each key K in A
      put flattenArray( A[K],  d1, d2, T,  X & K & d2 )  into T
   end repeat
end flattenArray

This yields the queried records in this format (just one record of many shown here).

[CDB Table ID]    1    [CDB Record ID]    cdb    cdbTableName    stats
[CDB Table ID]    1    [CDB Record ID]    cdb    cdbCloudSyncVersion    1

I then loop through the lines and remove the first two columns, then I filter out the lines with "cdb" keys not needed in my app as long as I preserve the record ID, and get a list of records like this…

[CDB Record ID]    ATTRIBUTES    fopn
[CDB Record ID]    LAST_NAME    Jordan
[CDB Record ID]    STATUS    linnm
[CDB Record ID]    RANK    2
[CDB Record ID]    CITY    San Francisco
[CDB Record ID]    YEAR    2019
[CDB Record ID]    ROLE    5
[CDB Record ID]    NAME    Sam Jordan
[CDB Record ID]    DATE    2019-02-17

Finally, I loop through the lines again and put the data for each record into the tab-delimited format I need, which is something roughly like this…

efrain.c and mark_talluto's suggestions for batch record creation and updates were VERY helpful. Thank you.

Does anybody have a simpler solution for this problem? Pretty sure there must be one (many). Thanks in advance.
