Perhaps my function can help you .. You have to adapt it to your input but after ou acces data as array named from column. Just look at the logic.
Please post your work in feedback if it works.

If you don't succeed, i can write the proper one but learning is better by doing ;^)
And the easiest way to fetch data from DB is using ADO, something like this (here your Sql command will be your SELECT * FROM table):
Connection = ADO.CreateConnection();
Connection.ConnectionString = ConnectionStr;
Connection.Open();
Command = ADO.CreateCommand();
while (Connection.State == adStateConnecting) {
aqUtils.Delay(qa.system.time.smaller);
i = i + 1;
if (i > 100) {
throw Error("Connection not opened within 10s");
}
}
Command.CommandText = Sql;
Command.CommandTimeout = CommandTimeout;
Command.ActiveConnection = Connection;
Results = Command.Execute();
ErrCount = Connection.errors.count;
if (ErrCount !== 0) {
for (Err = 0; Err == ErrCount; Err++){
Err = Connection.errors.item;
Error = Error + Err;
}
Connection.Errors.Clear;
throw Error;
}
else {
if ((Results != null) && (Results.RecordCount !== 0)) {
FunctionResult.Lines = Results.GetRows().toArray();
}
FunctionResult.Count = Results.RecordCount;
}
BenoitB Thanks much for providing some insights into this.
I see that you have a function as an array variable which has a JSON object 'functionResult'. That would store the 'data table' in 'data' array as a value. 'data' gets all the elements from 'temp' object which in turn contains row data separated by commas(,) ?
I have a few questions.
I really appreciate your help and the direction you've given. I'm still trying to understand this piece.
On the other hand, I have another function which has an ADO connection and runs a query. After that it makes a call to the routine:
dbRecordToObject(record)This fetches single record at a time and that gets pushed to a set like this: but this is really slow
var set = conn.Execute_(exeQuery);
//declare an array
var elementList = [];
Log.Message("INFO: set.EOF is: " +set.EOF);
if(set.EOF == false){
set.MoveFirst();
while(!set.EOF)
{
//get the result set into the array
elementList.push(dbRecordToObject(set));
set.MoveNext();
}
//Closing the connection
conn.Close();
return elementList;
Thank you

Ok, i'd done two posts because you asked about two things if i understood correctly.
First post is about transforming linear data in 2D array.
Use google translate to translate the documentation because i made effort to document then make the effort to translate 😁
And getTokenBySeparator take a token from a string, using a separator to find tokens ... 😂
Second post is about, root cause of your problem, speed.
If you look the second post, the speed problem could be resolved simply, call the set.GetRows() instead of navigating into ADO result set, so it would be:
let set = conn.Execute_(exeQuery);
let elementList = [];
if ((set != null) && (set.RecordCount != 0))
elementList = set.GetRows().toArray();
return elementList;
What you do was to browse Ado result set one by one to rebuild an array instead of fetching all data directly, so it's very slow.
Some info on GetRows() is here:
https://www.w3schools.com/asp/met_rs_getrows.asp
BTW try to implement error management and connection established waiting as it is in my code. Your code will be robust and in case of errors you can know where and what.
And don't put comment on trivial things (e.g. // Declare an array) or // Closing connection), comments are for advanced technical or algorithm points.
I invite you to take a glance to this post about method writing:
