MS Access query multiple criteria - ms-access

I am trying to build an access query with multiple criteria. The table to be queried is "tblVendor" which has information about vendor shipment data as shown below:
The second table is "tblSchedule" which has the schedule for each Vendor cutoff date. This table has cutoff dates for data analysis.
For each vendor, I need to select records which have the ShipDate >= CutoffDate. Although not shown in the data here, it may be possible that multiple vendors have same CutoffDate.
For small number of records in "tblCutoffdate", I can write a query which looks like:
SELECT tblVendors.ShipmentId, tblVendors.VendorNumber, tblVendors.VendorName,
tblVendors.Units, tblVendors.ShipDate
FROM tblVendors INNER JOIN tblCutoffDate ON tblVendors.VendorNumber =
tblCutoffDate.VendorNumber
WHERE (((tblVendors.VendorNumber) In (SELECT VendorNumber FROM [tblCutoffDate] WHERE
[tblCutoffDate].[CutoffDate] = #2/1/2014#)) AND ((tblVendors.ShipDate)>=#2/1/2014#)) OR
(((tblVendors.VendorNumber) In (SELECT VendorNumber FROM [tblCutoffDate] WHERE
[tblCutoffDate].[CutoffDate] = #4/1/2014#)) AND ((tblVendors.ShipDate)>=#4/1/2014#));
As desired, the query gives me a result which looks like:
What concerns me now is that I have a lot of records being added to the "tblCutoffDate" which makes it difficult for me to hardcode the dates in the query. Is there a better way to write the above SQL statement without any hardcoding?

You might try something like -- this should handle vendors having no past cutoff,
or those having no future cutoff
"today" needs a suitable conversion to just date w/o time
comparison "=" may go on both, or one, or none Max/Min
"null" may be replaced by 1/1/1900 and 12/31/3999 in Max/Min
SELECT tblvendors.shipmentid,
tblvendors.vendornumber,
tblvendors.vendorname,
tblvendors.units,
tblvendors.shipdate
FROM tblvendors
LEFT JOIN
( SELECT vendornum,
Max( iif cutoffdate < today, cutoffdate, null) as PriorCutoff,
Min( iif cutoffdate >= today, cutoffdate, null) as NextCutoff
FROM tblcutoffdate
GROUP BY vendornum
) as VDates
ON vendornumber = vendornum
WHERE tblvendors.shipdate BETWEEN PriorCutoff and NextCutoff
ORDER BY vendornumber, shipdate, shipmentid

A simpler WHERE clause should give you what you want.
SELECT
v.ShipmentId,
v.VendorNumber,
v.VendorName,
v.Units,
v.ShipDate
FROM
tblVendors AS v
INNER JOIN tblCutoffDate AS cd
ON v.VendorNumber = cd.VendorNumber
WHERE v.ShipDate >= cd.CutoffDate;

SUM inside SUM SQL Invalid use of group function

Hi I want to perform a calculation inside a SUM with my sql, but there is one SUM field that consist of other SUM fields. I get the General error: 1111 Invalid use of group function. What is the proper way of summing other sum fields in SQL?
I can't use the alias of other sum fields to perform the calculation because it says that the alias is unidentified.
This part is my problem
SUM((SUM(transactions.payable) + SUM(transactions.discount) ) - SUM(deliveries.delivery_fee) ) AS raw_sales
Thank you
Here is my SQL.
SELECT
MONTHNAME(transactions.date_transac) AS MONTH,
SUM(transactions.payable) AS total,
SUM(transactions.discount) AS discount,
SUM(deliveries.delivery_fee) AS delivery,
SUM(
(
SUM(transactions.payable) + SUM(transactions.discount)
) - SUM(deliveries.delivery_fee)
) AS raw_sales,
MONTH(transactions.date_transac) AS monthnum
FROM
`transactions`
LEFT JOIN `requisitions` ON `transactions`.`requisition_id` = `requisitions`.`id`
LEFT JOIN `transactions` AS `ct`
ON
`transactions`.`code` = `ct`.`charge_transaction_code`
LEFT JOIN `deliveries` ON `transactions`.`delivery_id` = `deliveries`.`id`
WHERE
`transactions`.`transaction_type` = Sale AND YEAR(`transactions`.`date_transac`) = 2020
GROUP BY
`month`
ORDER BY
`monthnum` ASC
enter image description here
You can't nest aggregate functions. Here, I suspect that you could move the arithmetics within the aggregate function rather than attempting to nest:
SUM(
transactions.payable
+ transactions.discount
- COALESCE(deliveries.delivery_fee, 0)
) AS raw_sales
delivery_fee comes from a left join table so it could be null, hence we use coalesce().
That said, I am quite suspicious about the logic of your query. I am wondering, for example, why transactions appears twice in the from clause. There are also missing quotes around literal string "Sale" in the WHERE clause. If you were to ask a legitimate question, including sample data, desired results, and an explanation of the purpose of the query, one might be able to suggests optimizations.
The query just worked, I haven't realized that it is no longer necessary to calculate all Sum fields. I just removed the external sum.

Retrieve customer revenue

I want to create a report with the top 20 customers (based on revenue).
I am using the query:
SELECT dbo.CustTable.AccountNum
,dbo.dirpartytable.NAME
,dbo.hcmworker.PERSONNELNUMBER
,dbo.CustInvoiceJour.SALESBALANCE
,dbo.custinvoicejour.QTY
FROM dbo.CustTable
inner JOIN dbo.HCMWORKER ON dbo.HCMWORKER.RECID = dbo.CustTable.KEV_Worker
inner join dbo.custInvoiceJour on CustInvoiceJour.OrderAccount = CustTable.AccountNum
inner join dbo.dirpartytable on dirpartytable.recid = custtable.PARTY
where CustTable.KEV_Worker = '5633561745'
ORDER BY SalesBalanceMst DESC
I can't find the relation for the customer revenue, after all, that is how I want to sort the report. I am sorting on SalesBalanceMST right now while building the report. Also I am getting multiple records when executing this query.
What am i doing wrong?
EDIT: I now realize I am showing each Invoice Journal, how can I display the Total Revenue of the customer?
A similar search from AX 2012:
CustInvoiceJour CustInvoiceJour;
CustTable CustTable;
DirPartyTable DirPartyTable;
select forceLiterals generateonly sum(SalesBalanceMST), sum(Qty) from CustInvoiceJour
where CustInvoiceJour.OrderAccount == '102372200'
&& CustInvoiceJour.InvoiceDate > today()-365
join TableId from CustTable
group AccountNum
where CustTable.AccountNum == CustInvoiceJour.OrderAccount
join TableId from DirPartyTable
group Name
where DirPartyTable.RecId == CustTable.Party;
info(CustInvoiceJour.getSQLStatement());
This shows the following SQL:
SELECT SUM(T1.SALESBALANCEMST),SUM(T1.QTY),T2.ACCOUNTNUM,T3.NAME
FROM CUSTINVOICEJOUR T1
CROSS JOIN CUSTTABLE T2
CROSS JOIN DIRPARTYTABLE T3
WHERE (((T1.PARTITION=5637144576) AND (T1.DATAAREAID=N'xxx'))
AND ((T1.ORDERACCOUNT=N'102372200')
AND (T1.INVOICEDATE>{ts '2015-11-06 00:00:00.000'})))
AND (((T2.PARTITION=5637144576) AND (T2.DATAAREAID=N'xxx'))
AND (T2.ACCOUNTNUM=T1.ORDERACCOUNT))
AND ((T3.PARTITION=5637144576)
AND (T3.RECID=T2.PARTY))
GROUP BY T2.ACCOUNTNUM,T3.NAME
ORDER BY T2.ACCOUNTNUM,T3.NAME
What is different from your query:
no join on HcmWorker, as I do not have your custom field.
Using sum() to aggregate
selecting on InvoiceDate
selection on OrderAccount
selection on DataAreaId, really important for performance, implicit in AX
selection on Partition, really important for performance, implicit in AX
You cannot directly sort on a sum, but may on a nested SQL query.
I do not know exactly what is wrong in your query but perhaps this information can help you.
Check this standard report CustTopCustomersbyYTDSales, It has some good queries to do that.

Reset a running total if field value is hit

I am able to keep a running total with the below query, and it does that just fine. What I really want, is when the gap field is greater than or equal to the date_diff field, the running total should reset back to the current hrly_qty. I'm sure I could achieve my results with a cursor, but I wanted to know of possible other ways. Ideas?
Example:
WITH CTE AS
(
SELECT a.*, SUM(b.hrly_qty) AS running_total, c.gap
FROM #tmpTrxhist2 a
INNER JOIN #tmpTrxhist2 b ON a.people_id = b.people_id
AND b.sequence_id <= a.sequence_id
INNER JOIN incent_level c ON a.owner_division_id = c.owner_division_id
GROUP BY a.date_diff, a.owner_division_id, a.people_id, a.sequence_id,
a.hrly_qty, c.gap
)
SELECT * FROM CTE
ORDER BY people_id, sequence_id
You seldom need a cursor! A simple case statement should suffice. Of the top of my head something like:
WITH CTE AS
(
SELECT a.*, SUM(b.hrly_qty) AS running_total, c.gap
FROM #tmpTrxhist2 a
INNER JOIN #tmpTrxhist2 b ON a.people_id = b.people_id
AND b.sequence_id <= a.sequence_id
INNER JOIN incent_level c ON a.owner_division_id = c.owner_division_id
GROUP BY a.date_diff, a.owner_division_id, a.people_id, a.sequence_id,
a.hrly_qty, c.gap
)
SELECT *,
CASE
WHEN gap >= date_diff then hrly_qty else gap
END as comp_gap
FROM CTE
ORDER BY people_id, sequence_id
Run the execution plans between the two but SQL is almost always much happier trying to optimise non-cursored code. In my field at least, you usually find cursors are over used and abused by 'proper' C/C++ programmers because they get in their comfort zone when see something that looks a bit like a while-loop rather than think about sets of data. There is a place for cursors, but this isn't it!

I need to sort by the most changed GROUP by in a table

I have a MySQL table called EssayStats with three columns, EssayDate, WordCount and EssayId.
Each row is a record of when the bot recorded how many words were in an essay at a particular point in time.
I'm trying to write a query that will group by EssayId and sort by the largest increase in WordCount from a particular EssayDate to an ending EssayDate.
I'm not really sure where to start. I've tried a handful of things but they obviously don't accomplish what I jeed. My most recent query attempt was
SELECT *
FROM EssayStats
WHERE EssayDate >= "2014-01-01" AND EssayDate <= "2014-05-31"
GROUP BY EssayId
ORDER BY (WordCount)
Start by getting the dates at the beginning and end for each essay. Then join back the original tables to get the counts and do some arithmetic:
select es.EssayId, (esmax.WordCount - esmin.WordCount)
from (select es.EssayId, min(es.EssayDate) as mined, max(es.EssayDate) as maxed
from EssayStats es
group by es.EssayId
) es join
EssayStats esmin
on es.EssayId = esmin.EssayId and es.mined = esmin.EssayDate join
EssayStats esmax
on es.EssayId = esmax.EssayId and es.maxed = esmax.EssayDate;

Counting the number min records within groups

I'm building a report for a database where I need to determine the number of "first scans" grouping by company, job, and date.
The scan table can contain multiple scans for the same item, however I only want to include the original scan in my COUNT, which can only be identified as being the scan with the earliest date that matches a particular item.
My first attempt at this was:
SELECT
_item_detail.job_id,
_item_group.group_id,
_scan.company_id,
DATE(scan_date_time) as scan_date,
COUNT(1)
FROM _scan
INNER JOIN _item_detail ON _item_detail.company_id = _scan.company_id
AND
_item_detail.serial_number = _scan.serial_number
INNER JOIN _item_group ON _item_group.group_id = _item_detail.group_id
WHERE _item_detail.job_id = '0326FCM' AND _scan.company_id = '152345' AND _item_group.group_id = 13
GROUP BY
_item_detail.job_id,
_item_group.group_id,
_scan.company_id, scan_date -- first_scan_count
HAVING min(scan_date_time);
This is giving me incorrect results, though (about 3x too many). I am assuming it's because the MIN record is being recalculated for each date, so if the min was found on day 1, it may also be found on day 3 and counted again.
How can I modify my query to achieve the desired results?
Something similar to this should work... I'm not completely sure of how your tables are laid out or how the data relates them together, but this is the general idea:
SELECT
_item_detail.job_id,
_item_group.group_id,
_scan.company_id,
DATE(scan_date_time) as scan_date,
COUNT(1)
FROM
_scan s1
INNER JOIN _item_detail
ON _item_detail.company_id = s1.company_id
AND _item_detail.serial_number = s1.serial_number
AND _item_detail.job_id = '0326FCM'
INNER JOIN _item_group
ON _item_group.group_id = _item_detail.group_id
AND _item_group.group_id = 13
WHERE
s1.company_id = '152345'
AND s1.scan_date_time = (
SELECT MIN(s2.scan_date_time)
FROM _scan s2
WHERE
s2.company_id = s1.company_id
AND s2.serial_number = s1.serial_number
)
GROUP BY
_item_detail.job_id,
_item_group.group_id,
s1.company_id
I don't quite follow your query, but based on the description of the problem, I'd say create a subquery that gives the min scan date for for each item, group by items, the perform your outer select on that.
