Cumulative Sum in Script

[AleRods88]

Hello,

I have the following table:

ID	DATE	TIME	TIME_SORT	VALUE
1	1/1/2019	6	1	1
1	1/1/2019	7	2	17
1	1/1/2019	8	3	5
1	1/1/2019	9	4	5
1	1/1/2019	10	5	7
1	1/1/2019	11	6	13
1	1/1/2019	12	7	0
1	1/1/2019	13	8	3
1	1/1/2019	14	9	8
1	1/1/2019	15	10	22
1	1/1/2019	16	11	23
1	1/1/2019	17	12	38
1	1/1/2019	18	13	31
1	1/1/2019	19	14	38
1	1/1/2019	20	15	30
1	1/1/2019	21	16	46
1	1/1/2019	22	17	46
1	1/1/2019	23	18	15
2	5/1/2019	1	2	5
2	5/1/2019	1	2	10

What I need is to add a colum named "cumulative" that makes a cumulative by ID and Date:

ID	DATE	TIME	TIME_SORT	VALUE	CUMULATIVE
1	1/1/2019	6	1	1	1
1	1/1/2019	7	2	17	18
1	1/1/2019	8	3	5	23
1	1/1/2019	9	4	5	28
1	1/1/2019	10	5	7	35
1	1/1/2019	11	6	13	48
1	1/1/2019	12	7	0	48
1	1/1/2019	13	8	3	51
1	1/1/2019	14	9	8	59
1	1/1/2019	15	10	22	81
1	1/1/2019	16	11	23	104
1	1/1/2019	17	12	38	142
1	1/1/2019	18	13	31	173
1	1/1/2019	19	14	38	211
1	1/1/2019	20	15	30	241
1	1/1/2019	21	16	46	287
1	1/1/2019	22	17	46	333
1	1/1/2019	23	18	15	348
2	5/1/2019	1	2	5	5
2	5/1/2019	1	2	10	15

Is there any way to do that?

Thank you!!!

Hi,

What you can do is create 2 keys.

1 for sorting and 1 for lookup

key1 will be ID,DATE, TIME and TIME_SORT

key2 will be ID and DATE

temp:
LOAD *,
ID & '_' & DATE&'_'& TIME & '_'* TIME_SORT as key1,

ID & '_' & DATE as key2
;
LOAD * INLINE [
ID, DATE, TIME, TIME_SORT, VALUE
1, 1/1/2019, 6, 1 ,1
1, 1/1/2019, 7 ,2 ,17
1, 1/1/2019, 8 ,3 ,5
1, 1/1/2019, 9 ,4 ,5
1, 1/1/2019, 10 ,5 ,7
1, 1/1/2019, 11 ,6 ,13
1, 1/1/2019, 12 ,7 ,0
1, 1/1/2019, 13 ,8 ,3
1, 1/1/2019, 14 ,9 ,8
1, 1/1/2019, 15 ,10 ,22
1, 1/1/2019, 16 ,11 ,23
1, 1/1/2019, 17 ,12 ,38
1, 1/1/2019, 18 ,13 ,31
1, 1/1/2019, 19 ,14 ,38
1, 1/1/2019, 20 ,15 ,30
1, 1/1/2019, 21 ,16 ,46
1, 1/1/2019, 22 ,17 ,46
1, 1/1/2019, 23 ,18 ,15
2, 5/1/2019, 1 ,2 ,5
2, 5/1/2019, 1 ,2 ,10
];

//Create a resident table that will order by your dataset using the key1.

//Then use the previous or peek function to compare the key2 if they are equal, if yes, then you should add the value. //if no then just get the value

final:
LOAD *,
if(peek(key2,-1)=key2, peek(CUMULATIVE,-1)+VALUE, VALUE) as CUMULATIVE//if(Previous(%key)=%key, previous(VALUE) + VALUE, VALUE) as testvalue,
;
LOAD * resident temp
order by key1 asc;

drop table temp;
