As user I want a function to calculate the yearly bonus and total column value by putting company revenue as input parameter and do the calculation based on criteria as follow:
Company revenue input cannot be higher then 1.000.000.000.000, assuming current revenue input is 350.000.000.000
Table format
| CustBalance |
|CustID | varchar(10) |
|CustName | varchar(200) |
|JoinDate | Date |
|Region | Varchar(50) |
|CurrBalance | Numeric(17,4) |
|YearlyBonus | Numeric(17,4) |
|Total | Numeric(17,4) |
Calculation process can be done by spesifict parameter, in exam by based on name or region filter (optional).
Count YearlyBonus as follow.
Only customer who join in 2020 will get yearly bonus.
Base on JoinDate criteria:
Join during Q1 will get additional 10% from company revenue input param
Join during Q2 will get additional 7,5% from company revenue input param
Join during Q3 will get additional 5% from company revenue input param
Join during Q4 will get additional 2,5% from company revenue input param
Base on Region criteria:
Region 1 will get additional 1% from their current balance
Region 2 will get additional 1% from their current balance
Region 3 will get additional 2,5% from their current balance
Count total by adding Yearly Bonus value and Current Balance value.
Sampel input
Output format:
The result should show the data condition on the Customer Balance table after the calculation process with currency format in Rupiah for column “Current Balance”, “Yearly Bonus”, “Total”.

Please note that I'm an absolute n00b in MySQL but somehow I managed to build some (for me) complex queries that work as they should. My main problem now is that for a many of the queries we're working on:
The querie is becoming too big and very hard to see through.
The same subqueries get repeated many times and that is adding to the complexity (and probably to the time needed to process the query).
We want to further expand this query but we are reaching a point where we can no longer oversee what we are doing. I've added one of these subqueries at the end of this post, just as an example.
!! You can fast foward to the Problem section if you want to skip the details below. I think the question can be answered also without the additional info.
What we want to do
Create a MySQL query that calculates purchase orders and forecasts for a given supplier based on:
Sales history in a given period (past [x] months = interval)
Current stock
Items already in backorder (from supplier)
Reserved items (for customers)
Supplier ID
I've added an example of a subquery at the bottom of this message. We're showing just this part to keep things simple for now. The output of the subquery is:
Part number
Units sold
Units sold (outliers removed)
Units sold per month (outliers removed)
Number of invoices with the part number in the period (interval)
It works quite OK for us, although I'm sure it can be optimised. It removes outliers from the sales history (e.g. one customer that orders 50 pcs of one product in one order). Unfortunately it can only remove outliers with substantial data, so if the first order happens to be 50 pcs then it is not considered an outlier. For that reason we take the amount of invoices into account in the main query. The amount of invoices has to exceed a certain number otherwise the system wil revert to a fixed value of "maximum stock" for that product.
As mentioned this is only a small part of the complete query and we want to expand it even further (so that it takes into account the "sales history" of parts that where used in assembled products).
For example if we were to build and sell cars, and we want to place an
order with our tyre supplier, the query calculates the amount of tyres we need to order based on the sales history of the various car models (while also taking into account the stock of the cars, reserved cars and stock of the tyres).
Problem
The query is becomming massive and incomprehensible. We are repeating the same subqueries many times which to us seems highly inefficient and it is the main cause why the query is becomming so bulky.
What we have tried
(Please note that we are on MySQL 5.5.33. We will update our server soon but for now we are limited to this version.)
Create a VIEW from the subqueries.
The main issue here is that we can't execute the view with parameters like supplier_id and interval period. Our subquery calculates the sum of the sold items for a given supplier within the given period. So even if we would build the VIEW so that it calculates this for ALL products from ALL suppliers we would still have the issue that we can't define the interval period after the VIEW has been executed.
A stored procedure.
Correct me if I'm wrong but as far as I know, MySQL only allows us to perform a Call on a stored procedure so we still can't run it against the parameters (period, supplier id...)
Even this workaround won't help us because we still can't run the SP against the parameters.
Using WITH at the beginning of the query
A common table expression in MySQL is a temporary result whose scope is confined to a single statement. You can refer this expression multiple times with in the statement.
The WITH clause in MySQL is used to specify a Common Table Expression, a with clause can have one or more comms-separated subclauses.
Not sure if this would be the solution because we can't test it. WITH is not supported untill MySQL version 8.0.
What now?
My last resort would be to put the mentioned subqueries in a temp table before starting the main query. This might not completely eliminate our problems but at least the main query will be more comprehensible and with less repetition of fetching the same data. Would this be our best option or have I overlooked a more efficient way to tackle this?
Many thanks for your kind replies.

Now, on to the query. You have LEFT JOINs to the artcred table, but then include artcred in the WHERE clause making it an INNER JOIN (required both left and right tables) in the result. Was this intended, or are you expecting more records in the bongegs table that do NOT exist in the artcred.
Well to be honest I was not fully aware that this would essentially form an INNER JOIN but in this case it doesn't really matter. A record that exists in bongegs always exists in artcred as well (every sold product must have a supplier). That doesn't work both ways since a product can be in artcred without ever being sold.
You also have RIGHT JOIN on totvrd which implies you want every record in the TotVRD table regardless of a record in the bongegs table. Is this correct?
Yes it is intended. Otherwise only products with actual sales in the period would end up in the result and we also wanted to include products with zero sales.
One simplification:
and b.aantal < ( SELECT * from ( SELECT AVG ...
-->
and b.aantal < ( SELECT AVG ...
A personal problem: my brain hurts when I see RIGHT JOIN; please rewrite as LEFT JOIN.
Check you RIGHTs and LEFTs -- that keeps the other table's rows even if there is no match; are you expecting such NULLs? That is, it looks like they can all be plain JOINs (aka INNER JOINs).
These might help performance:
b: INDEX(bon_soort, bon_datum, aantal, art_code)
totvrd: INDEX(art_code)
artcred: INDEX(vln, cred_nr, art_code)
Is b the what you keep needing? Build a temp table:
CREATE TEMPORARY TABLE tmp_b
SELECT ...
FROM b
WHERE ...;
But if you need to use tmp_b multiple times in the same query, (and since you are not yet on MySQL 8.0), you may need to make it a non-TEMPORARY table for long enough to run the query. (If you have multiple connections building the same permanent table, there will be trouble.)
Yes, 5.5.33 is rather antique; upgrade soon.
(pre
By getting what I believe are all the pieces you had, I think this query significantly simplifies the query. Lets first start with the fact that you were trying to eliminate the outliers by selecting the standard deviation stuff as what to be excluded. Then you had the original summation of all sales also from the bongegs table.
To simplify this, I have the sub-query ONCE internal that does the summation, counts, avg, stddev of all orders (f) within the last 6 months. I also computed the divide by 6 for per-month you wanted in the top.
Since the bongegs is now all pre-aggregated ONCE, and grouped per art_code, it does not need to be done one after the other. You can use the totals directly at the top (at least I THINK is similar output without all actual data and understanding of your context).
So the primary table is the product table (Voorraad) and LEFT-JOINED to the pre-query of bongegs. This allows you to get all products regardless of those that have been sold.
Since the one aggregation prequery has the avg and stddev in it, you can simply apply an additional AND clause when joining based on the total sold being less than the avg/stddev context.
The resulting query below.
SELECT
-- appears you are looking for the highest percentage?
-- typically NOT a good idea to name columns starting with numbers,
-- but ok. Typically let interface/output name the columns to end-users
GREATEST((b.verkocht_sdperMonth * ((100 + 0)/100)),0) as 'units sold p/month',
-- appears to be the total sold divided by 6 to get monthly average over 6 months query of data

I have created a users table that holds names and phone numbers (users).
id| name | phone
1 | Frank | 0345221234
2 | Sara | 0342555939
I got another table that holds a log with user's calls to different numbers (call_logs):
number | destination | price
0345221234 | destination | x /// This is Frank
0345221234 | destination | y /// This is also Frank
0342555939 | destination | z /// This is Sara
And then I have a table that holds numbers that Frank and Sara are allowed to call (allowed_numbers):
number
033485733
045727728
082358288
I would like to loop through my users table and based on their number to check the calls log table and select the SUM of price column for log records where destination does not match the allowed numbers table so that I know the cost for calls not in the allowed list.
Then I want to select SUM of price column for log records where destination DO match
the allowed numbers table so that I know how much did the allowed calls cost.
Is there any way I can do this in a single query with sub-queries and all needed in order to achieve this result set:
users number | SUM(price) of allowed calls | SUM(price) of calls not allowed
Thank you!
SELECT call_logs.number
,SUM(IF(allowed_numbers.number IS NOT NULL,call_logs.price,0)) AS AllowedPrice
,SUM(IF(allowed_numbers.number IS NULL,call_logs.price,0)) AS NotAllowedPrice
FROM call_logs
LEFT JOIN allowed_numbers
ON call_logs.destination = allowed_numbers.number
GROUP BY call_logs.number;
I have a db table named APPLICATION that has the following columns
applicationnumber varchar,
createddate datetime,
applicantname varchar,
material varchar,
location varchar
I am needed to write a query that would display the number of applications created for each month for the locations
Eg. The query result should be something like below
Location | Jan2012 | Feb2012 | Mar2012 | Apr2012
-----------------------------------------------------------------
London | 34322342 | 4342424 | 54353454 | 5434
Chicago| 43242345 | 9943455 | 85748294 | 544
The result is the number of applications created in each month for the specific location.
Each column will execute the same query logic, with just the month changing.
I tried using the MONTH() function, but I need the month matrix as a column and not as a row.
You can use the DATE_FORMAT function on the createddate field to only get the month and year and then GROUP BY location. Something like this should do it:
SELECT
`location`,
COUNT(`applicationnumber`),
DATE_FORMAT(`createddate`, '%M %Y') AS `date`
FROM `APPLICATION`
GROUP BY `location`;
Should give a result with the count of rows per month.
I run a report in mysql which returns all active members and their associated plan selections. If a member is terminated, this is displayed on the report as well. The issue I am facing, however is when a member simply decides to 'change' plans. Our system effective 'terminates' the original plan and starts fresh with the new one while keeping the original enrollment information for the member.
Sample report data may look like the following:
MemberID | Last | First | Plan Code | Original Effective | Change Date | Term Date
--------------------------------------------------------------------------------------------
12345 | Smith | John | A | 05-01-2011 | | 06-01-2011
12345 | Smith | John | B | 06-01-2011 | |
In the example above, a member had plan code A from May 1, 2011 to June 1, 2011. On June 1, 2011, the member changed his coverage to Plan B (and is still active since no term or change data).
Ultimately, I need my report to generate the following instead of the 2 line items above:
MemberID | Last | First | Plan Code | Original Effective | Change Date | Term Date
--------------------------------------------------------------------------------------------
12345 | Smith | John | B | 05-01-2011 | 06-01-2011 |
which shows his original plan effective date, the date of the change, and leaves the termination field blank.
I know I can get into a single row by using Group By the Member ID and I can even add the change date into the appropriate field with a (IF COUNT() > 1) statement but I am not able to figure out how to show the correct plan code (C) or how to leave the term date blank keeping the original effective date.
Any ideas?
Although I hate columns with embedded spaces and having to tick them, this should do it for you. The PreQuery will detect how many policy entries there are, preserve the first and last too, grouped by member. Once THAT is done, it can re-join the the plan enrollment on the same member but matching ONLY for the last "Original Effective" date for the person... That will give you the correct Plan Code. Additionally, if the person was terminated, it's date would be filled in for you. If still employed, it will be blank on that record.
select STRAIGHT_JOIN
pe2.MemberID,
pe2.Last,

join PlanEnrollment pe2
on PreQuery.MemberID = pe2.MemberID

I remember having the problem, but not coming up with a GROUP BY-based solution ;)
Instead, I think you can do something like
SELECT memberid, plancode
FROM members
INNER JOIN plans ON members.id=plans.member_id
WHERE plans.id IN
(SELECT id FROM plans
WHERE member_id = members.id
ORDER BY date DESC
LIMIT 0,1)
