Goal: Create a query to pull the closest cycle count event (Table C) for a product ID based on the inventory adjustments results sourced from another table (Table A).
All records from Table A will be used, but is not guaranteed to have a match in Table C.
The ID column will be present in both tables, but is not unique in either, so that pair of IDs and Timestamps together are needed for each table.
Current simplified SQL
SELECT
A.WHENOCCURRED,
A.LPID,
A.ITEM,
A.ADJQTY,
C.WHENOCCURRED,
C.LPID,
C.LOCATION,
C.ITEM,
C.QUANTITY,
C.ENTQUANTITY
FROM
A
LEFT JOIN
C
ON A.LPID = C.LPID
WHERE
A.facility = 'FACID'
AND A.WHENOCCURRED > '23-DEC-22'
AND A.ADJREASONABBREV = 'CYCLE COUNTS'
ORDER BY A.WHENOCCURRED DESC
;
This is currently pulling the first hit on C.WHENOCCURRED on the LPID matches. Want to see if there is a simpler JOIN solution before going in a direction that creates 2 temp tables based on WHENOCCURRED.
I have a functioning INDEX(MATCH(MIN()) solution in Excel but that requires exporting a couple system reports first and is extremely slow with X,XXX row tables.
If you are using Oracle 12 or later, you can use a LATERAL join and FETCH FIRST ROW ONLY:
SELECT A.WHENOCCURRED,
A.LPID,
A.ITEM,
A.ADJQTY,
C.WHENOCCURRED,
C.LPID,
C.LOCATION,
C.ITEM,
C.QUANTITY,
C.ENTQUANTITY
FROM A
LEFT OUTER JOIN LATERAL (
SELECT *
FROM C
WHERE A.LPID = C.LPID
AND A.whenoccurred <= c.whenoccurred
ORDER BY c.whenoccurred
FETCH FIRST ROW ONLY
) C
ON (1 = 1) -- The join condition is inside the lateral join
WHERE A.facility = 'FACID'
AND A.WHENOCCURRED > DATE '2022-12-23'
AND A.ADJREASONABBREV = 'CYCLE COUNTS'
ORDER BY A.WHENOCCURRED DESC;
I have this complex data relationship.
POSTGRESQL FIDDLE: https://www.db-fiddle.com/f/vm2z8qLuddzcHEgyaMnCbc/3
"Item Group" has many "items" through "item_ads" table.
So an Item Group has many part_number.
reports table contains the number of clicks for each day for each adgroupid.
Each adgroupid has_many part_numbers. (table: product_ads)
Now, I want to SUM all reports.clicks for each item_groups.id using the part_number to linked the tables.
After this, I have to consider only reports.adgroupid which are included in the part_numbers of item_group. So if "Item group" has three part_number (A, B, C) can be considered all adgroupid that contains A,B, or C but nothing more. If adgroupid contains part_number D it cannot be considered for clicks sum.
Expected results
I have to have a table with lots of item_group_ids.
I am looking for the PostgreSQL query to achieve this table.
First, let's build the query up in parts. It sounds like you already know how to get from item_group and adgroup to part_number, just not about how to join them. I've added a query that removes duplicates for part 1 of your question, but putting them into a CTE:
WITH unique_part_numbers AS (
SELECT DISTINCT item_groups.id AS item_group_id,
part_number
FROM item_groups
JOIN item_ads ON item_group_id = item_groups.id
JOIN items ON items.id = item_ads.item_id
)
SELECT unique_part_numbers.item_group_id, SUM(clicks)
FROM unique_part_numbers
JOIN product_ads ON product_ads.part_number = unique_part_numbers.part_number
JOIN reports ON product_ads.adgroupid = reports.adgroupid
GROUP BY item_group_id
About the second part - it's not possible to do it as you want, because you can have multiple adgroups per item_group - so I added adgroupid as an extra column. I create an array of part_numbers for the adgroup and check, using the #> operator, that all parts that are from the adgroupid are also from the unique_part_numbers.item_group_id.
WITH unique_part_numbers AS (
SELECT DISTINCT item_groups.id AS item_group_id,
part_number
FROM item_groups
JOIN item_ads ON item_group_id = item_groups.id
JOIN items ON items.id = item_ads.item_id
)
SELECT unique_part_numbers.item_group_id,
product_ads.adgroupid,
array_agg(unique_part_numbers.part_number),
SUM(clicks)
FROM unique_part_numbers
JOIN product_ads ON product_ads.part_number = unique_part_numbers.part_number
JOIN reports ON product_ads.adgroupid = reports.adgroupid
GROUP BY item_group_id, product_ads.adgroupid
HAVING array_agg(product_ads.part_number) #> (
SELECT ARRAY_AGG(other_product_ads.part_number)
FROM product_ads AS other_product_ads
WHERE other_product_ads.adgroupid = product_ads.adgroupid
)
I have a 2 tables FIRST
id,rl_no,adm_date,fees
1,123456,14-11-10,100
2,987654,10-11-12,30
3,4343,14-11-17,20
and SECOND
id,rollno,fare,type
1,123456,20,bs
5,634452,1000,bs
3,123456,900,bs
4,123456,700,bs
My requirement is twofold,
1, i first need to get all columns from both tables with common rl_no. So i used:
SELECT a.ID,a.rl_no,a.adm_date,a.fees,b.rollno,b.fare,b.type FROM FIRST a
INNER JOIN
SECOND b ON a.rl_no = b.rollno
The output is like this:
id,rl_no,adm_date,fees,rollno,fare,type
1,123456,14-11-10,100,123456,20,bs
1,123456,10-11-12,100,123456,900,bs
1,123456,14-11-17,100,123456,700,bs
2,Next i wanted to get the sum(fare) of those rollno that were common between the 2 tables and also whose fare >= fees from FIRST table group by rollno and id.
My query is:
SELECT x.ID,x.rl_no,,x.adm_date,x.fees,x.rollno,x.type,sum(x.fare) as "fare" from (SELECT a.ID,a.rl_no,a.adm_date,a.fees,b.rollno,b.fare,b.type FROM FIRST a
INNER JOIN
SECOND b ON a.rl_no = b.rollno) x, FIRST y
WHERE x.rollno = y.rl_no AND x.fare >= y.fees AND x.type IS NOT NULL GROUP BY x.rollno,x.ID ;
But this is throwing in exceptions.
ORA-00979: not a GROUP BY expression
00979. 00000 - "not a GROUP BY expression"
The expected output will be like this:
id,rollno,adm_date,fare,type
1,123456,14-11-10,1620,bs
So could someone care to show an oracle newbie what i'm doing wrong here?
It looks like there's a couple different problems here;
Firstly, you're trying to group by an x.ID column which doesn't exist; it looks like you'll want to add ID to the selected columns in your sub-query.
Secondly, when aggregating with GROUP BY, all selected columns need to be either listed in the GROUP BY statement or aggregated. If you're grouping by rollno and ID, what do you want to have happen to all the extra values for adm_date, fees, and type? Are those always going to be the same for each distinct rollno and ID pair?
If so, simply add them to the GROUP BY statement, ie,
GROUP BY adm_date, fees, type, rollno, ID
If not, you'll need to work out exactly how you want to select which one to be output; If you've got output like your example (adding in an ID column here)
ID,adm_date,fees,rollno,fare,type
1,14-11-10,100,123456,20,bs
1,10-11-12,100,123456,900,bs
1,14-11-17,100,123456,700,bs
Call that result set 'a'. If I run;
SELECT a.ID, a.rollno, SUM(a.fare) as total_fare
FROM a
GROUP BY a.ID, a.rollno
Then the result will be a single row;
ID,rollno,total_fare
1,123456,1620
So, if you also select the adm_date, fees, and type columns, oracle has no idea what you mean to do with them. You're not using them for grouping, and you're not telling oracle how you want to pick which one to use.
You could do something like
SELECT a.ID,
FIRST(a.adm_date) as first_adm_date,
FIRST(a.fees) as first_fees,
a.rollno,
SUM(a.fare) as total_fare,
FIRST(a.type) as first_type
FROM a
GROUP BY a.ID, a.rollno
Which would give the result;
ID,first_adm_date,first_fees,rollno,total_fare,first_type
1,14-11-10,100,123456,1620,bs
I'm not sure if that's what you mean to do though.
I was having some trouble with an SQL 2k sproc and which we moved to SQL 2k5 so we could used Table Value UDF's instead of Scalar UDF's.
This is simplified, but this is my problem.
I have a temporary table that I fill up with product information. I then pass that product information into a UDF and return the information back to my main results set. It doesn't seem to work.
Am I not allowed to pass a Temporary Table value into an CROSS APPLY'd Table Value UDF?
--CREATE AND FILL #brandInfo
SELECT sku, upc, prd_id, cp.customerPrice
FROM products p
JOIN #brandInfo b ON p.brd_id=b.brd_id
CROSS APPLY f_GetCustomerPrice(b.priceAdjustmentValue, b.priceAdjustmentAmount, p.Price) cp
--f_GetCUstomerPrice uses the AdjValue, AdjAmount, and Price to calculate users actual price
When I put dummy values in for b.priceAdjustmentValue and b.priceAdjustmentAmount it works great. But as soon as I try to load the temp table values in it bombs.
Msg 207, Level 16, State 1, Line 140
Invalid column name 'b.priceAdjustmentValue'.
Msg 207, Level 16, State 1, Line 140
Invalid column name 'b.priceAdjustmentAmount'.
Have you tried:
--CREATE AND FILL #brandInfo
SELECT sku, upc, prd_id, cp.customerPrice
FROM products p
JOIN #brandInfo b ON p.brd_id=b.brd_id
CROSS APPLY (
SELECT *
FROM f_GetCustomerPrice(b.priceAdjustmentValue, b.priceAdjustmentAmount, p.Price) cp
)
--f_GetCUstomerPrice uses the AdjValue, AdjAmount, and Price to calculate users actual price
Giving the UDF the proper context in order to resolve the column references?
EDIT:
I have built the following UDF in my local Northwind 2005 database:
CREATE FUNCTION dbo.f_GetCustomerPrice(#adjVal DECIMAL(28,9), #adjAmt DECIMAL(28,9), #price DECIMAL(28,9))
RETURNS TABLE
AS RETURN
(
SELECT Level = 'One', AdjustValue = #adjVal, AdjustAmount = #adjAmt, Price = #price
UNION
SELECT Level = 'Two', AdjustValue = 2 * #adjVal, AdjustAmount = 2 * #adjAmt, Price = 2 * #price
)
GO
And referenced it in the following query without issue:
SELECT p.ProductID,
p.ProductName,
b.CompanyName,
f.Level
FROM Products p
JOIN Suppliers b
ON p.SupplierID = b.SupplierID
CROSS APPLY dbo.f_GetCustomerPrice(p.UnitsInStock, p.ReorderLevel, p.UnitPrice) f
Are you certain that your definition of #brandInfo has the priceAdjustmentValue and priceAdjustmentAmount columns defined on it? More importantly, if you are putting this in a stored procedure as you mentioned, does there exist a #brandInfo table already without those columns defined? I know #brandInfo is a temporary table, but if it exists at the time you attempt to create the stored procedure and it lacks the columns, the parsing engine may be getting tripped up. Oddly, if the table doesn't exist at all, the parsing engine simply glides past the missing table and creates the SP for you.
Is there any other way for returning rows for the same id by joining two tables and return the row if any of the columns value for the same id is different.
Select Table1.No,Table2.No,Table1.Name,Table2.Name,Table1.ID,Table2.ID,Table1.ID_N,Table2.ID_N
From MyFirstTable Table1
JOIN MySecondTable Table2
ON Table1.No=Table2.No where Table1.ID!=Table2.ID or Table1.ID_N != Table2.ID_N
In the example above , I have only two columns I need to check but in my real case there are at least 20 .
Is there any other statment I can use instead of enumerating each column in the where codition?
...WHERE BINARY_CHECKSUM(Table1.*) <> BINARY_CHECKSUM(Table2.*)
or
...WHERE BINARY_CHECKSUM(Table1.Field1, Table1.Field2, ...) <> BINARY_CHECKSUM(Table2..Field1, Table2.Field2, ...)
*this assumes you have no blob fields in your tables

If No is a PK
Select Table1.No,Table1.Name,Table1.ID,Table1.ID_N
From MyFirstTable Table1
