While transposing single columns is pretty straight forward I need to transpose a large amount of data with 3 sets of , 10+ related columns needed to be transposed.
create table test
(month int,year int,po1 int,po2 int,ro1 int,ro2 int,mo1 int,mo2 int, mo3 int);
insert into test
values
(5,2013,100,20,10,1,3,4,5),(4,2014,200,30,20,2,4,5,6),(6,2015,200,80,30,3,5,6,7) ;
select * FROM test;
gives
month
year
po1
po2
ro1

mo1

Transposing using UNPIVOT
select
month, year,
PO, RO, MO
from ( SELECT * from test) src
unpivot
( PO for Description in (po1, po2))unpiv1
unpivot
(RO for Description1 in (ro1, ro2)) unpiv2
unpivot
(MO for Description2 in (mo1, mo2, mo3)) unpiv3
order by year
Gives me this
month

Maybe use a query like below which creates rows as per your design using CROSS APPLY
select month,year,po,ro,mo from
test cross apply
(values (po1,ro1,mo1), (po2,ro2,mo2),(0,0,mo3))v(po,ro,mo)
see demo here
Unpivot acts similar as union,Use union all in your case
SELECT month,
year,
po1 AS PO,
ro1 AS RO,
mo1 AS MO
FROM test
UNION ALL
SELECT month,
year,
po2,
ro2,
mo2
FROM test
UNION ALL
SELECT month,
year,
0,
0,
mo2
FROM test
I am using MS Access and I am trying to create a query between two tables and merge same rows base on:
cust_id = cust_id and
a_date = f_date and
price = paid
and have the desire output.
My data now:
tblapp
app_id cust_id a_date price a_memo
------------------------------------------
1 1 10/10/20 20 hello
2 1 11/10/20 10 bye
3 2 12/10/20 30 hi
4 2 12/10/20 30 text
5 2 12/10/20 30 lol
6 2 12/10/20 30 ciao
7 3 14/10/20 25 peace
tblfin
fin_id cust_id f_date paid
----------------------------------
1 1 10/10/20 20
2 1 11/10/20 10
3 1 11/10/20 10
4 2 12/10/20 30
5 3 14/10/20 25
As you can see,
cust_id = 1 on 10/10/20 with bill 20 and paid 20
cust_id = 1 on 11/10/20 with bill 10 and paid 10 + 10
cust_id = 2 on 12/10/20 with bill 30 + 30 + 30 + 30 and paid 30
cust_id = 3 on 14/10/20 with bill 25 and paid 25
Derire query output:
app_id cust_id a_date price a_memo fin_id cust_id f_date paid
----------------------------------------------------------------------
1 1 10/10/20 20 hello 1 1 10/10/20 20
2 1 11/10/20 10 bye 2 1 11/10/20 10
3 2 12/10/20 30 hi 4 2 12/10/20 30
7 3 14/10/20 25 peace 5 3 14/10/20 25
Tried the following sql but i am getting duplicates(like cust_id 1 and 2 where data rows are not the same in two tables):
SELECT f.fin_id,
f.cust_id,
f.f_date,
f.paid,
a.app_id,
a.cust_id,
a.a_date,
a.price,
a.a_memo
FROM tblfin AS f
LEFT JOIN tblapp AS a ON (f.cust_id=a.cust_id)
AND (f.f_date=a.a_date)
AND (f.paid=a.price);
Solution using MySQL is welcome. Thank you.
I got two tables. One with a bill of material and one with purchasing orders. Now I want to display the full bill of material of a product with the total on order amounts from the table purchasing.
**Billofmaterials**
BOM_ID BOM_Prod_id BOM_item_id
1 5 11
2 5 13
3 6 11
4 6 15
5 6 20
Example prod_id (product id) 6 has 3 items (id 11, 15 and 20).
**Purchasing**
PU_ID PU_item_id PU_amount PU_status
1 11 100 On order
2 11 650 On order
3 11 40 Received
4 20 600 On order
5 8 10 On order
6 15 150 Received
Now i got the following SQL
SELECT
BOM_item_id,
SUM(DISTINCT purchasing.PU_amount) as total_on_order
FROM Billofmaterials
LEFT JOIN purchasing
ON Billofmaterials.BOM_item_id= purchasing.PU_item_id
AND purchasing.PU_status != 'Received'
AND BOM_prod_id = 6
GROUP BY BOM_item_id
This query returns the following:
**Query result**
BOM_item_id total_on_order
11 750
20 600
Because there is only one received purchase order for BOM_item_id 15 it doesn't return a value. Now i want to retun BOM_item_id 15 also but with a total_on_order as 0 like:
**Expected result**
BOM_item_id total_on_order
11 750
15 0
20 600
What SQL feature/function do I need to use to get the expected result?
You can try the below -
SELECT BOM_item_id,coalesce(total_on_order,0) as total_on_order
FROM Billofmaterials left join
(
select PU_item_id,SUM(purchasing.PU_amount) as total_on_order
from purchasing
where purchasing.PU_status != 'Received'
group by PU_item_id
) purchasing
ON Billofmaterials.BOM_item_id= purchasing.PU_item_id
where BOM_prod_id = 6
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...
Given the following tables
table message
id message time_send
14 "first" 2014-02-10 22:16:31
15 "second" 2014-02-14 09:35:20
16 "third" 2014-02-13 09:35:47
17 "fourth" 2014-03-10 22:16:31
18 "fifth" 2014-03-14 09:35:20
19 "sixth" 2014-04-12 09:35:47
20 "seventh" 2014-04-13 09:35:47
21 "eighth" 2014-04-14 09:35:47
table message_owner
id message_id owner_id cp_id
1 14 1 4
2 14 4 1
3 15 12 4
4 15 4 12
5 16 4 1
6 16 1 4
7 17 12 4
8 17 4 12
9 18 4 1
10 18 1 4
11 19 12 4
12 19 4 12
13 20 12 1
14 20 1 12
15 21 12 7
16 21 7 12
I want to query the most recent message with every counter party(cp_id) for a given owner.
For example for owner_id=4 I would like the following output:
id message time_send owner_id cp_id
18 "fifth" 2014-03-14 09:35:20 4 1
19 "sixth" 2014-02-13 09:35:47 4 12
I see a lot of examples with one table but I am not able to transpose them in a multitable example.
edit1: adding more entries
This should work:
SELECT m.id, m.message, mo.owner_id, mo.cp_id
FROM message m
JOIN message_owner mo ON m.id=mo.message_id
WHERE mo.owner_id=4
AND m.time_send=(
SELECT MAX(time_send)
FROM message m2
JOIN message_owner mo2 ON mo2.message_id=m2.id
WHERE mo2.owner_id=mo.owner_id
AND mo2.cp_id =mo.cp_id
)
... notice though that putting a WHERE condition on a timestamp column can sometimes not work correctly.
Same example without jointures:
SELECT m.id, m.time_send, m.message, mo.owner_id, mo.cp_id
FROM message m, message_owner mo
WHERE m.id = mo.message_id
AND mo.owner_id = 4
AND m.time_send = (
SELECT MAX(time_send)
FROM message m2, message_owner mo2
WHERE mo2.message_id = m2.id
AND mo2.owner_id = mo.owner_id
AND mo2.cp_id = mo.cp_id
);
