I have 3 tables: Deliveries, IssuedWarehouse, ReturnedStock.
Deliveries: ID, OrderNumber, Material, Width, Gauge, DelKG
IssuedWarehouse: OrderNumber, IssuedKG
ReturnedStock: OrderNumber, IssuedKG
What I'd like to do is group all the orders by Material, Width and Gauge and then sum the amount delivered, issued to the warehouse and issued back to stock.
This is the SQL that is really quite close:
SELECT
DELIVERIES.Material,
DELIVERIES.Width,
DELIVERIES.Gauge,
Count(DELIVERIES.OrderNo) AS [Orders Placed],
Sum(DELIVERIES.DeldQtyKilos) AS [KG Delivered],
Sum(IssuedWarehouse.[Qty Issued]) AS [Film Issued],
Sum([Film Retns].[Qty Issued]) AS [Film Returned],
[KG Delivered]-[Film Issued]+[Film Returned] AS [Qty Remaining]
FROM (DELIVERIES
INNER JOIN IssuedWarehouse
ON DELIVERIES.OrderNo = IssuedWarehouse.[Order No From])
INNER JOIN [Film Retns]
ON DELIVERIES.OrderNo = [Film Retns].[Order No From]
GROUP BY Material, Width, Gauge, ActDelDate
HAVING ActDelDate Between [start date] And [end date]
ORDER BY DELIVERIES.Material;
This groups the products almost perfectly. However if you take a look at the results:
Material Width Gauge Orders Placed Delivered Qnty Kilos Film Issued Film Returned Qty Remaining

You'll see that there are some materials that have the same width and gauge yet they are not grouped. I think this is because the delivered qty is different on the orders. For example:
Material Width Gauge Orders Placed Delivered Qnty Kilos Film Issued Film Returned Qty Remaining
LDPE 620 50 1 252 252 67 67
LDPE 660 50 1 256 256 62 62
I would like these two rows to be grouped. They have the same material, width and gauge but the delivered qty is different therefore it hasn't grouped it.
Can anyone help me group these strange rows?
Your "problem" is that the deliveries occurred on different dates, and you're grouping by ActDelDate so the data splits, but because you haven't selected the ActDelDate column, this isn't obvious.
The fix is: Remove ActDelDate from the group by list
You should also remove the unnecessary brackets around the first join, and change
HAVING ActDelDate Between [start date] And [end date]
to
WHERE ActDelDate Between [start date] And [end date]
and have it before the GROUP BY
You are grouping by the delivery date, which is causing the rows to be split. Either omit the delivery date from the results and group by, or take the min/max of the delivery date.

I have a data table derived via unstacking an existing dataframe:
Day 0 1 2 3 4 5 6
Hrs
0 223 231 135 122 099 211 217
1 156 564 132 414 156 454 157

4 111 264 469 330 671 201 345
-- -- -- -- -- -- -- --
I want to simply change the column titles so I have the days of the week displayed instead of numbered. Something like this:
Day Mon Tue Wed Thu Fri Sat Sun
Hrs
0 223 231 135 122 099 211 217
1 156 564 132 414 156 454 157
2 950 178 121 840 143 648 192
3 025 975 151 185 341 145 888
4 111 264 469 330 671 201 345
-- -- -- -- -- -- -- --
I've tried .rename(columns = {'original':'new', etc}, inplace = True) and other similar functions, none of which have worked.
I also tried going to the original dataframe and creating a dt.day_name column from the parsed dates, but it come out with the days of the week mixed up.
I'm sure it's a simple fix, but I'm living off nothing but caffeine, so help would be appreciated.
You can try:
import pandas as pd
df = pd.DataFrame(columns=[0,1,2,3,4,5,6])
df.columns = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
I have df1 which has three columns (loadgroup, cartons, blocks) like this
loadgroup
cartons
blocks
cartonsPercent
blocksPercent
1
2269
14
26%
21%
2
1168
13
13%
19%

5
1686
9
19%
13%
total(sum of column)
8813
68
100%
100%
The interpretation is like this: out of df1 26% cartons which is also 21% of blocks are assigned to loadgroup 1, etc. we can assume blocks are 1 to 68, cartons are 1 to 8813.
I also have df2 which also has cartons and blocks columns. but does not have loadgroup.
My goal is to assign loadgroup (1-5 as well) to df2 (100 blocks 29608 cartons in total), but keep the proportions, for example, for df2, 26% cartons 21% blocks assign loadgroup 1, 13% cartons 19% blocks assign loadgroup 2, etc.
df2 is like this:
block

29608 cartons
I want to add loadgroup column to df2, try to keep those proportions as close as possible. How to do it please? Thank you very much for the help.
I don't know how to find loadgroup column based on both cartons percent and blocks percent. But generate random loadgroup based on either cartons percent or blocks percent is easy.
Here is what I did. I generate 100,000 seeds first, then for each seed, I add column loadgroup1 based on cartons percent, loadgroup2 based on blocks percent, then calculate both percentages, then compare with df1 percentages, get absolute difference, record it. For these 100,000 seeds, I take the minimum difference one as my solution, which is sufficient for my job.
But this is not the optimal solution, and I am looking for quick and easy way to do this. Hope somebody can help.
Here is my code.
df = pd.DataFrame()
np.random.seed(10000)
seeds = np.random.randint(1, 1000000, size = 100000)
for i in range(46530, 46537):
print(seeds[i])
np.random.seed(seeds[i])
df2['loadGroup1'] = np.random.choice(df1.loadgroup, len(df2), p = df1.CartonsPercent)
df2['loadGroup2'] = np.random.choice(df1.loadgroup, len(df2), p = df1.blocksPercent)
df2.reset_index(inplace = True)
three = pd.DataFrame(df2.groupby('loadGroup1').agg(Cartons = ('cartons', 'sum'), blocks = ('block', 'count')))
three['CartonsPercent'] = three.Cartons/three.Cartons.sum()
three['blocksPercent'] = three.blocks/three.blocks.sum()
four = df1[['CartonsPercent','blocksPercent']] - three[['CartonsPercent','blocksPercent']]
four = four.abs()
subdf = pd.DataFrame({'i':[i],'Seed':[seeds[i]], 'Percent':['CartonsPercent'], 'AbsDiff':[four.sum().sum()]})
df = pd.concat([df,subdf])
three = pd.DataFrame(df2.groupby('loadGroup2').agg(Cartons = ('cartons', 'sum'), blocks = ('block', 'count')))
three['CartonsPercent'] = three.Cartons/three.Cartons.sum()
three['blocksPercent'] = three.blocks/three.blocks.sum()
four = df1[['CartonsPercent','blocksPercent']] - three[['CartonsPercent','blocksPercent']]
four = four.abs()
subdf = pd.DataFrame({'i':[i],'Seed':[seeds[i]], 'Percent':['blocksPercent'], 'AbsDiff':[four.sum().sum()]})
df = pd.concat([df,subdf])
df.sort_values(by = 'AbsDiff', ascending = True, inplace = True)
df = df.head(10)
Actually the first row of df will tell me the seed I am looking for, I kept 10 rows just for curiosity.
Here is my solution.

It's very close to my target though.
To be clear, I'm not a developer, I'm just a business analyst trying to achieve something in Access which has stumped me.
I have a table of values as such:

I would like to create a query using SQL in Access to create grouping as follows:
Area Code Week Start Week End
232 1 12
232 35 39
232 41 52
330 1 4
330 33 45
330 47 50
However everything I have read leads me to use the ROWNUM() function which is not native to Access.
I'm OK with general queries in Access, but am not very familiar with SQL.
How can I go about achieving my task?
Thanks
Mike
Use another database! MS Access doesn't have good functionality (in general).
You can do what you want, but it is expensive:
select area, min(week), max(week)
from (select t.*,
(select count(*)
from t as t2
where t2.area = t.area and t2.week <= t.week
) as seqnum
from t
) as t
group by area, (week - seqnum);
The correlated subquery is essentially doing row_number().
have a schema with 9 fields and i want to take only two fields(6,7 i.e $5,$6) and i want to calculate the average of $5 and i want to sort the $6 in ascending order so how to do this task can some one help me.

i have written the code like this but it is not working properly:
a = load '/path/to/file' using PigStorage('\t');
b = foreach a generate (int)$5 as field_a:int,(chararray)$6 as field_b:chararray;
c = group b all;
d = foreach c generate b.field_b,AVG(b.field_a);
e = order d by field_b ASC;
dump e;
I am facing error at order by:
grunt> a = load '/user/horton/sample_pig_data.txt' using PigStorage('\t');
grunt> b = foreach a generate (int)$5 as fielda:int,(chararray)$6 as fieldb:chararray;
grunt> describe #;
b: {fielda: int,fieldb: chararray}
grunt> c = group b all;
grunt> describe #;
c: {group: chararray,b: {(fielda: int,fieldb: chararray)}}
grunt> d = foreach c generate b.fieldb,AVG(b.fielda);
grunt> e = order d by fieldb ;

{ (72) , (83) , (87) , (75) , (93) , (90) , (78) , (89) }),83.375)
If you have found the answer, best practice is to post it so that others referring to this can have a better understanding.
Can you please help on this, Im trying to write a query which retrieves a total amount from an array of columns, I dont know if there is a way to do this, I retrieve the array of columns I need from this query:
USE Facebook_Global
GO
SELECT c.name AS column_name
FROM sys.tables AS t
INNER JOIN sys.columns AS c
ON t.OBJECT_ID = c.OBJECT_ID
WHERE t.name LIKE '%Lifetime Likes by Gender and###$%' and c.name like '%m%'
Which gives me this table
column_name
M#13-17
M#18-24
M#25-34
M#35-44
M#45-54
M#55-64
M#65+
So I need a query that gives me a TotalAmount of those columns listed in that table. Can this be possible?
Just to clarify a little:
I have this table
Date F#13-17 F#18-24 F#25-34 F#35-44 F#45-54 F#55-64 F#65+ M#13-17 M#18-24 M#25-34 M#35-44 M#45-54 M#55-64 M#65+

And I need a column with a SUM of all the columns containing the word F and other containig the word M, instead of using something like this:
F#13-17+F#18-24+F#25-34+F#35-44+F#45-54+etc.
Is this possible?
Try something like this:
with derivedTable as
(sql from your question goes here)
select column_name
from derivedTable
union
select cast(count(*) as varchar (10) + 'records'
from derivedTable
