Partition of cumulative sum of length
Hello
I'm working on a code to work around the limitation of wm_concat. Please consider the following data:
string_data
---------
AAAAA
BBB
CCC
DELAHAYE
EA
FFFFFF
GG
HARMAN
To this day, I have the following statement:
Sum (length (string_data)) (string_data order)
My current results are:
AAAAA 5
BBB 8
CCC 11
DDDDDDD 18
I want to do is be able to break once reached a certain length, say for example 12. So, I want to wm_concat on this particular window or a set of results. Example:
YYYY, BBB, CCC
DELAHAYE, EE
FFFFFF, GG
Is someone can please help me overcome this barrier?
Thank you very much.
Try this:
with the data as
(
Select "AAAAA" str in union double all the
Select "BBB-" of all the double union
Select "CCC" in all the double union
Select 'VAL' Union double all the
Select 'EE' of all the double union
Select 'FFFFFF' Union double all the
Select "GG" of all the double union
Select "HARMAN" double
)
SELECT MAX (new_str)
DE)
SELECT new_str, grp
FROM (SELECT * FROM data ORDER BY str)
DIMENSION of the MODEL BY (rn ROWNUM) measures (CAST (str AS VARCHAR2 (4000)) new_str, str, grp 0)
RULES)
new_str [any] order by rn = CASE WHEN CV (rn) > 1 AND LENGTH (new_str [cv () - 1] |) «, » || Str [CV ()])<=12 then="">
Of ANOTHER str [cv ()]
END
GRP [any] = nvl (grp [cv () - 1], 0) + BOX WHEN new_str [cv ()] = str [cv ()] then 1 else 0 end
)
)
GROUP BY grp;

find the cumulative sum of the previous columns
Hello
How can I get the cumulative sum of a particular column in the preceding lines in the current line.
e.g. I have a table produced,
Date | Orders
__________________
1 JANUARY 10 | 3
JANUARY 2, 10. 5
JANUARY 3, 10. 1
I want to select the date and orders between the 1st and the 3rd. Something like...
Select the Date, the orders for products where Date between to_date('1-JAN-10') and to_date('3-JAN-10')
But I want the output like this...
Date | Orders
__________________
1 JANUARY 10 | 0
JANUARY 2, 10. 3
JANUARY 3, 10. 8
Similarly, when I select it between 2 and 3, I want the output voltage...
Date | Orders
_________________
JANUARY 2, 10. 3
JANUARY 3, 10. 8
and so on. In the output, orders here are the cumulative sum of the previous columns.
Published by: eric clapton, November 8, 2010 20:45Hello
Use the analytical SUM function.
You want to filter by date after the cumulative SUM is calculated, so calculate the SUM in a subquery, then filter by date no later than:WITH got_cm_orders AS ( SELECT dt , orders , SUM (orders) OVER (ORDER BY dt) - orders AS cm_orders FROM products ) SELECT dt , orders WHERE dt BETWEEN DATE '2010-01-02' AND DATE '2010-01-03' ; -

How to calculate a running sum, A = A + B, in Labview? I've seen some exaples of how to do it with process variables, a while loop and registers at offset. A loop time won't work in my application because it calculates the sum of each waiting period. Where I want to sum only when new orders X and are sent to a stepper motor controller.
The sums of X and Y will be used to show how an X and table Y went from a "Home" position.

Either a business structure or a selection function will work. The structure of the case is perhaps easier. Develop the structure of the case around the addition, with add it inside of the case of fake. In the case of true, connect the value that you add directly to the exit tunnel (not more). This way you can reset any value you want. The value to add will be outside the structure of the case, of course, and for maximum efficiency, it is also suitable for outside the while loop. If this is not clear, or you want someone to check your work, attach your VI. Make sure that you reset the first time you run the VI (or handle this within the race in summary VI by using the "First Call" function and OR the output with the reset entry).

Total cumulative peform Records
My requirement is to make the accumulated amount while they inspected the highest bonus.
Here are the files in the sample.
create the table test_cumsum as
(select 100 'id', 5 'bonus', 0.25 "CLTS', 'y' flg in union double all the)
Select 3, 200, 0.25, 'y' from dual union all
Select 300,1,0.15, 'y' from dual union all
Select 400,2,0.25, 'y' from dual union all
Select 500,6,0.25, 'y' in the double)
From the award-winning sum the CLTS hightest until the cumulative sum = 1
Records that are left in the running sum must be updated with flg = N
In the example above the SumOf CLTS for 6,5,3,2 bonus will be equal to 1
So record id = 300 must be updated to flg = N as long as this record needs no summation of the value to 1
Please suggest!
Could not test this carefully... but something like this may work. Test it with improved sample just to audit data.
----------
SELECT "id", "bonus", "crdts", CASE WHEN SUM ( "crdts") OVER (PARTITION BY 1 ORDER BY "bonus" DESC ROWS UNBOUNDED PRECEDING) <= 1 THEN 'Y' ELSE 'N' END flg FROM test_cumsum;ID bonus CLTS FLG 500 6 0.25 THERE 100 5 0.25 THERE 200 3 0.25 THERE 400 2 0.25 THERE 300 1 0.15 N p.s. Please name the columns without quotation marks double... its just pain
See you soon,.

I get good results, but the query performs a lot better when I use COUNT (*) OVER (PARTITION BY user_id, order_item_id) for the name.
Is it possible to PARTITION BY the sums with the additional conditions for good and bad?

I want to generate a vector that is the cumulative sum of another vector without using a loop. My vector is more than 10 ^ 6 length and a loop takes forever. I use cumsum in matlab, but could not find something similar in labview.
Thank you!
It works for a 1 d of 1 million items table... you need to mod a little for a 2d array but it takes hardly any time at all to run. You must have an inefficiency in your code. If you make columns or lines, I can mod a bit for you, but you should try it on your own first using this example.

Valid time intervals: two tables intersect documents
Benefits:
I have two tables:
AVAILABILITY (ALLOCATION A_ID, START_TIME, END_TIME, ID_RESSOURCE)
TASK (T_ID, START_TIME, END_TIME, ID_RESSOURCE)
My final request should print:
Id_ressource, DAY_OF_WEEK, MYDATE, DURATION (in hours)
Semantics back: "give me all the time slots available; Time slot available to the general public is the time range that does not contain a task"
1. in the tables above START_TIME, END_TIME are of type DATE and they contain a timestamp that is to say:
SELECT to_char (START_TIME, 'HH24 MMDDYYYY') from the AVAILABILITY/TASK
would print something like
09232014 14:17
2. in the tables above time START_TIME and END_TIME are of the same date and END_TIME > START_TIME IE
START_TIME = 09232014 14:17
END_TIME = 09232014 15:17
no need to check that
3. If for some date there are TASK BOTH records and AVAILABILITY, then it must be:
TASK. End_time < = AVAILABILITY. End_time and TASK. Start_time = > AVAILABILITY. START_TIME
In other words, JOB registration is still "inside" free and BUSY folder
I need time slots which are essentially output
-All available records that do not contain a ' ' tasks.
AVAILABILITY. Id_ressource, to_char (AVAILABILITY. Start_time, 'DAY') as DAY_OF_WEEK, AVAILABILITY. Start_time as MYDATE, (AVAILABILITY. END_TIME-AVAILABILITY. Start_time) * 24 as DURATION
AND
-If the free and busy folder contains task (see 3) then there are 2 two time intervals resulting (Yes the duration can be 0)
AVAILABILITY. Id_ressource, to_char (AVAILABILITY. Start_time, 'DAY') as DAY_OF_WEEK, AVAILABILITY. Start_time as MYDATE, (TASK. START_TIME-AVAILABILITY. Start_time) * 24 as DURATION
and
AVAILABILITY. Id_ressource, to_char (AVAILABILITY. Start_time, 'DAY') as DAY_OF_WEEK, AVAILABILITY. Start_time as MYDATE, (AVAILABILITY. END_TIME-TASK. End_time) * 24 as DURATION
Hope the above makes sense. What is the best, more rapid SQL?
Hello
Here's a way to do it:
WITH union_data AS
(
SELECT id_ressource, change_time, change_val
AVAILABILITY
UNPIVOT (change_time
FOR change_val IN (start_time AS 1
end_time AS - 1
)
)
UNION ALL
SELECT id_ressource, change_time, change_val
TASK
UNPIVOT (change_time
FOR change_val IN (start_time AS 1
end_time AS - 1
)
)
)
got_change_sum AS
(
SELECT id_ressource
change_time
SUM (change_val) OVER (PARTITION BY id_ressource
ORDER BY change_time
) AS change_sum
Advance (change_time) OVER (PARTITION BY id_ressource
ORDER BY change_time
) - change_time AS long
Of union_data
)
SELECT id_ressource
, TO_CHAR (change_time, 'fmDay, FMMM-DD-YYYY') AS available_date
Duration * 24 AS available_hours
OF got_change_sum
WHERE change_sum = 1
ORDER BY id_ressource
change_time
;
To see how it works, view the results of each auxiliary request individually.
You will see that the union_data product has all the points where either avaialablity or a task changes. The column change_val is + 1 availability or a task at the beginning and - 1, when it ends. When the cumulative sum of those is 0, this means that there is no availability. When the accumulated amount is > 1, this means a task is underway. We are interested in the places where the cumulative sum of change_val is exactly 1, sense that a period which started (but not yet completed) and that there is a net 0 current tasks.
This solution is NOT the value of start_time and end_time in the same day of calendar and tasks for the same resource may overlap.

Insert table when missing data

I have the following table, for readability I cracked the after each manager for each file number. The last column is the cumulative sum of the second last column. Value for month should ideally go 1 - 3 (as we see in both cases to Chicago). But the table, you can see in some cases, some entries are missing (marked by <-).

fiscal_total = value of the previous row. For example, for the missing first line should be:

Hi, I have a query that calculates the length total telephone lines which are put into service (in service) and not private for a period (V_DATE_FROM & V_DATE_TO) data as shown below:
SELECT SUM (NVL (c.length, 0))
OF tel_lines c
WHERE (c.code, c.date_commissioned)
IN
(SELECT c1.code, MAX (c1.date_commissioned)
Tel_lines C1
WHERE the c1.date_commissioned <: V_DATE_TO
AND (c1.date_decommissioned >: V_DATE_FROM)
GOLD date_decommissioned IS NULL)
AND (c1.date_privately_owned >: V_DATE_FROM)
GOLD c1.date_privately_owned IS NULL)
GROUP BY c1.code)
For example, my V_DATE_FROM is 01/01/2011 and my V_DATE_TO is 30/06/2011. As a result, I got the total length of the lines put into service as of 30/06/2011. If a line has been downgraded Let's say 01/03/2011, the length of this line will not appear in the calculation of the length total for the period January-June 2011 but is included for the period January-February 2011. Thus, it is possible that the January-February period will have a higher value in the period from January to June.
Now, what I want to do is to get the MONTHLY TOTAL LENGTH HIGHER for a given period, such as if the total for the period January-June 2011 is on February, then what I would get either the value of February for the period Jan-June 2011.
I hope that my explanation is understood. Thanks in advance for the help.Hello

( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen YEAR_WEEK_NUM ------------- 30 31 32 33 342. must be added BACKLOG_WEEK_WH_AFTR_ATP lines in the calculations for the first week in the report
SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re / ITEM_NUMBE QUANTITY YEAR_WEEK_NUM ---------- ---------- ------------- ITEM_1 200 30 ITEM_2 600 30 ITEM_1 -200 30 ITEM_1 -100 33 ITEM_2 -300 30 ITEM_2 -200 32 ITEM_3 -800 30 ITEM_3 -400 343. we must now repeat weekly, generated by the request of row_gen against all of the item_numbers returned by the above query and match them if possible to get the amount. Where there is no entry in BACKLOG_WEEK_WH_AFTR_ATP or BACKLOG_ATP_GT_CW_IN for a number of the week, we should use 0 as the quantity. The Partition Outer Join does for us.
SQL> select 2 re.item_number, 3 row_gen.year_week_num, 4 NVL(re.quantity,0) qty 5 from 6 ( SELECT 7 to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num 8 FROM 9 DUAL 10 CONNECT BY LEVEL <= 5 11 ) row_gen LEFT OUTER JOIN 12 ( SELECT 13 le.item_number, 14 le.quantity, 15 to_number(to_char(sysdate,'IW'))+1 year_week_num 16 FROM 17 BACKLOG_WEEK_WH_AFTR_ATP le 18 UNION ALL 19 SELECT 20 re.item_number, 21 -re.quantity, 22 to_number(substr(re.year_week,-2,2)) year_week_num 23 FROM 24 BACKLOG_ATP_GT_CW_IN re 25 ) re 26 PARTITION BY (re.item_number) 27 ON ( row_gen.year_week_num = re.year_week_num) 28 / ITEM_NUMBE YEAR_WEEK_NUM QTY ---------- ------------- ---------- ITEM_1 30 200 ITEM_1 30 -200 ITEM_1 31 0 ITEM_1 32 0 ITEM_1 33 -100 ITEM_1 34 0 ITEM_2 30 -300 ITEM_2 30 600 ITEM_2 31 0 ITEM_2 32 -200 ITEM_2 33 0 ITEM_2 34 0 ITEM_3 30 -800 ITEM_3 31 0 ITEM_3 32 0 ITEM_3 33 0 ITEM_3 34 -400 17 rows selected.4. now, we have the base dataset that we need - she has all the amounts with the right directions so that we can simply add everything up as a sum of sumulative. That's what makes OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) SUM (NVL(re.quantity,0)) bit. He said baseically are all lines seen so far in the result set for each item number...
select re.item_number, row_gen.year_week_num, NVL(re.quantity,0) qty, SUM(NVL(re.quantity,0)) OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) quantity from ( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen LEFT OUTER JOIN ( SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re ) re PARTITION BY (re.item_number) ON ( row_gen.year_week_num = re.year_week_num) / ITEM_NUMBE YEAR_WEEK_NUM QTY QUANTITY ---------- ------------- ---------- ---------- ITEM_1 30 200 0 ITEM_1 30 -200 0 ITEM_1 31 0 0 ITEM_1 32 0 0 ITEM_1 33 -100 -100 ITEM_1 34 0 -100 ITEM_2 30 -300 300 ITEM_2 30 600 300 ITEM_2 31 0 300 ITEM_2 32 -200 100 ITEM_2 33 0 100 ITEM_2 34 0 100 ITEM_3 30 -800 -800 ITEM_3 31 0 -800 ITEM_3 32 0 -800 ITEM_3 33 0 -800 ITEM_3 34 -400 -12005. we can now rotate these data in columns - however, there is a small problem. For points 1 and 2 we have 2 lines for the week 30, running in the quantity column total is the same for both because the two lines appear at the same point in the game as defined by the order by clause. This means before rotate us, we must select one of the lines - or the other will do, they are both correct. If we do not have, the effect will be to double the cumulative sum (for point 1 is 0, so it does not appear) for this, we can use the ROW_NUMBER function...
select re.item_number, row_gen.year_week_num, NVL(re.quantity,0) qty, SUM(NVL(re.quantity,0)) OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) quantity, ROW_NUMBER() OVER(PARTITION BY re.item_number, row_gen.year_week_num ORDER BY NULL) rn from ( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen LEFT OUTER JOIN ( SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re ) re PARTITION BY (re.item_number) ON ( row_gen.year_week_num = re.year_week_num) / ITEM_NUMBE YEAR_WEEK_NUM QTY QUANTITY RN ---------- ------------- ---------- ---------- ---------- ITEM_1 30 200 0 1 ITEM_1 30 -200 0 2 ITEM_1 31 0 0 1 ITEM_1 32 0 0 1 ITEM_1 33 -100 -100 1 ITEM_1 34 0 -100 1 ITEM_2 30 -300 300 1 ITEM_2 30 600 300 2 ITEM_2 31 0 300 1 ITEM_2 32 -200 100 1 ITEM_2 33 0 100 1 ITEM_2 34 0 100 1 ITEM_3 30 -800 -800 1 ITEM_3 31 0 -800 1 ITEM_3 32 0 -800 1 ITEM_3 33 0 -800 1 ITEM_3 34 -400 -1200 16. so now that we have a way to select one of the duplicate lines, we can move forward a pivot data by ensuring that us choose only 'first' line for each element for each week...
SELECT item_number, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+1 THEN quantity END ) plus_1, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+2 THEN quantity END ) plus_2, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+3 THEN quantity END ) plus_3, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+4 THEN quantity END ) plus_4, SUM ( CASE WHEN year_week_num = to_number(to_char(sysdate,'IW'))+5 THEN quantity END ) plus_5 FROM ( select re.item_number, row_gen.year_week_num, SUM(NVL(re.quantity,0)) OVER(PARTITION BY re.item_number ORDER BY row_gen.year_week_num) quantity, ROW_NUMBER() OVER(PARTITION BY re.item_number, row_gen.year_week_num ORDER BY NULL) rn from ( SELECT to_number(to_char(sysdate,'IW')) + ROWNUM year_week_num FROM DUAL CONNECT BY LEVEL <= 5 ) row_gen LEFT OUTER JOIN ( SELECT le.item_number, le.quantity, to_number(to_char(sysdate,'IW'))+1 year_week_num FROM BACKLOG_WEEK_WH_AFTR_ATP le UNION ALL SELECT re.item_number, -re.quantity, to_number(substr(re.year_week,-2,2)) year_week_num FROM BACKLOG_ATP_GT_CW_IN re ) re PARTITION BY (re.item_number) ON ( row_gen.year_week_num = re.year_week_num) ) WHERE rn = 1 GROUP BY item_numberYou need not add a join between BACKLOG_WEEK_WH_AFTR_ATP and BACKLOG_ATP_GT_CW_IN, because we are all summed up in the article number and all item numbers, we have selected two tables. The aggregation ensures that the quantities are added together against the item number.
