Nested Query example using ARRAY_AGG and ROW_NUMBER()

Hi Team, Im doing a scheduling plan and i need to get a nested query where I can get an array of values and another array where i can get the row from i took the previous values, im assuming that would be 2 queries and i tried to create the first one.

Please see below:

Table results=Table.query("SELECT ARRAY_AGG([Qty(01/04/2023)]) AS total FROM GlobalTable1 WHERE [Qty(01/04/2023)]!=0 AND (([***]) !='D'OR'A'))";`
return results[1][1];


//Expected Result (40,30,5)
//And another query that told me from what rows what taken the first array like (2,7,10)

Could you help me to modify the example please?

Thanks a lot for the support!

The end of your query (OR 'A') doesn't make sense. Either write multiple conditions with an AND or use the IN operator.

You can get the same result without the ARRAY_AGG operator. The only thing that changes is the format of the result table. When cloning the result table you either get two arrays, one with the values and one with the rows. Or you get an array of tuples (value, row number).
