usage
The image shows works that I have done in access. The query "overall usage review" count the number of usages in each month by using combined query.
After this step, I want to show the maximum three of usage.quantity among 12months and calculate with the formula ( E.g., "Total MAX three months usage"/3)
E.g.,
Warehouse Part Number ........................................................
A X01 9 16 7 14 10 5 9 11 6 3 11 5
A X02 20 22 10 12 20 17 18 29 14 13 11 19
B X01 8 7 3 26 17 6 3 2 5 10 8 14
B X05 9 10 16 6 10 4 13 12 6 4 3 6
I want to result it as below...
Warehouse Part Number Maximum three usage quantity Results
A X01 41 41/3
A X02 71 71/3
B X01 57 19
B X05 39 13
Someone told me to use dynamic sql, but I dont know what it is... Pls tell me how to solve this problem in detail. The problem stuck in my mind for a very long time...

I have a dataset, in which it has a lot of entries for a single location. I am trying to find a way to sum up all of those entries without affecting any of the other columns. So, just in case I'm not explaining it well enough, I want to use a dataset like this:
Locations Cyclists maleRunners femaleRunners maleCyclists femaleCyclists
Bedford 10 12 14 17 27
Bedford 11 40 34 9 1
Bedford 7 1 2 3 3
Leeds 1 1 2 0 0
Leeds 20 13 6 1 1
Bath 101 20 33 41 3
Bath 11 2 3 1 0
And turn it into something like this:
Locations Cyclists maleRunners femaleRunners maleCyclists femaleCyclists
Bedford 28 53 50 29 31
Leeds 21 33 39 1 1
Bath 111 22 36 42 3
Now, I have read up that a groupby should work in a way, but from my understanding a group by will change it into 2 columns and I don't particularly want to make hundreds of 2 columns and then merge it all. Surely there's a much simpler way to do this?
IIUC, groupby+sum will work for you:
df.groupby('Locations',as_index=False,sort=False).sum()
Output:
Locations Cyclists maleRunners femaleRunners maleCyclists femaleCyclists
0 Bedford 28 53 50 29 31
1 Leeds 21 14 8 1 1
2 Bath 112 22 36 42 3
Pivot table should work for you.
new_df = pd.pivot_table(df, values=['Cyclists', 'maleRunners', 'femalRunners',
'maleCyclists','femaleCyclists'],index='Locations', aggfunc=np.sum)
I have a query where I would like to manipulate a column to return an array conatining only the max-value from the last 12 values from another column (due to other parts of the query).
Example:
I want to add the column MaxLast12 from:
Month Power
1 10
2 16
3 8
4 14
5 15
6 3
7 6
8 10
9 11
10 12
11 12
12 12
13 18
14 12
To become:
Month Power MaxLast12
1 10 10
2 16 16
3 8 16
4 14 16
5 15 16
6 3 16
7 6 16
8 17 17
9 11 17
10 12 17
11 12 17
12 12 17
13 18 18
14 12 18
It would also help to be able to create a simpler solution where I only include the 12 rows in the query (won't be as accurate but good enough for the purpose) with only the maximum value. Would need to do the following:
Month Power
1 6
2 6
3 8
4 14
5 15
6 3
7 6
8 10
9 11
10 12
11 12
12 12
To become:
Month Power YearMax
1 10 17
2 16 17
3 8 17
4 14 17
5 15 17
6 3 17
7 6 17
8 17 17
9 11 17
10 12 17
11 12 17
12 12 17
Since I'm guessing both problems solution will be similar, any help possible is appriciated. Would like to avoid usign GROUP BY clause since I'm modifying an existing kind of complex query.
Tried to achive this using max() with no luck.
I am using SQL-developer.
In Oracle you would use window functions:
select month, power,
max(power) over (order by month rows between 11 preceding and current row)
from t;
Thanks in advance for any assistance you can provide. I have spent hours on this with no luck.
I'm working with an indented bill of material table which has an end part id, a sequence number, a level and a quantity. The goal is to determine the total cumulative quantity of each row on this table.
What makes this difficult is that to determine the total quantity, the child quantity needs to be multiplied by it's parent quantity. The parent quantity of that parent needs to be multiplied by it's parent quantity and so on.
For example, a level 3 part has a component quantity of 5. It's parent the level 2 part has a component quantity of 2. It's parent the level 1 part has a component quantity of 3. This means the level 3 part total quantity is 30 (3 X 2 X 5).
With the assistance of SO (specifically #KKK) the parent quantity was able to be calculated in the below query. After this was resolved I realized I now need two additional columns, one that shows the Rolled/Cumulative quantities of the parent rows and one that shows the total quantity of the child.
The attached screenshot has the two columns that need to be added highlighted in yellow. Here is the current SQL (using Oracle 10.2) for the columns that are not in yellow:
select
end_part_id, sort_seq_no, indented_lvl, comp_qty,
(select distinct first_value(a.comp_qty) over (order by a.sort_seq_no desc, TRIM(a.indented_lvl) desc)
from
report_table a
where
a.end_part_id = b.end_part_id
and a.sort_seq_no < b.sort_seq_no
and TRIM(a.indented_lvl) < TRIM(b.indented_lvl)) as "PARENT_QTY"
from report_table b
Expected Results
END_PART_ID SORT_SEQ_NO INDENTED_LVL COMP_QTY PARENT_QTY ROLLED_PARENT QTY TOTAL_QTY
PARTX 1 1 2 1 1 2
PARTX 2 2 5 2 2 10
PARTX 3 3 2 5 10 20
PARTX 4 4 1 2 20 20
PARTX 5 5 1 1 20 20
PARTX 6 6 1 1 20 20
PARTX 7 5 4 1 20 80
PARTX 8 6 1 4 80 80
PARTX 9 2 7 2 2 14
PARTX 10 3 2 7 14 28
PARTX 11 3 2 7 14 28
PARTX 12 4 1 2 28 28
PARTX 13 4 1 2 28 28
PARTX 14 3 8 7 14 112
PARTX 15 1 1 1 1 1
PARTX 16 2 7 1 1 7
PARTX 17 3 2 7 7 14
PARTX 18 3 2 7 7 14
PARTX 19 4 1 2 14 14
PARTX 20 4 1 2 14 14
HI expert and need your help me on the below requirement in oracle.
I have list of columns and from that I need to know based on the Model No. column filter if the other columns have any duplicate values, if yes then it should display comments column as Column Name + duplicate value (Ex: Category_description having duplicate value)
If the any of the column is blank it should print Column Name is blank (Ex: Parent Category ID has blank value).
The data is:
M_No CAT_DESC CAT_ID P_CAT_ID Comments
1 computer hardware 10 90
1 monitors 11 10
1 printers 12 10
1 harddisks 13 10 CAT_DESC duplicate
1 memory components 14 10
1 harddisks 15 10 CAT_DESC duplicate
1 keyboards, mouses 16 10
1 other peripherals 17 10
1 harddisks 19 10 CAT_DESC duplicate
2 office fur supplies 30 90
2 capitalizable assets 31 30
2 office daily use 32 30
2 manuals, other books 33 30 CAT_DESC, CAT_ID duplicate
2 manuals, other books 33 30 CAT_DESC, CAT_ID duplicate
3 computer hardware 90 P_CAT_ID is blank value
4 computer software 20 90
4 spreadsheet software 21 20
4 processing software 22 20
4 23 CAT_DESC, P_CAT_ID is blank

I have a daily sales report query and it have 2 columns like
days sales
1 12
2 65
3 25
...
30 24
but when I want to print it there is a lots of free spaces on paper, so I want to seperate query with a percentage (like % 33)
and result will be like 3 x 2 columns for one paper. and it will be more comfortable for me.
days sales days sales days sales
1 12 11 21 21 5
2 65 12 53 22 18
3 25 13 0
...
10 45 20 12 30 55
Any way to do this with DevEx Grid?
this is the view which I get
and I dont want such kind of empty paper for couple of records..
You will not find an easy way to achieve the desired result using XtraGrid, because it is not intended for reporting. I suggest that you create reports using another product: XtraReports.
