Edit of Row in Access - sql

I have table which looks like this:
ID
NameOfProduct
Quantity
Price1 in USD
Price 2 in USD
1
Energy
5
3,5
2,7
2
Gas
10
3
21,2
Then I created form based on this table, which is a Splitform. I want to create a button which would allow me to create a correction of chosen row.
It should create another row with negative values of the corrected row (only the columns which are numeric), because I don't want to erase the row, I need the evidence for later how the original row looked like and then it would allow me to edit values of selected row and add it into the table as another row
I have no idea how to even start with this - If I can do this by only using macros, or SQL or do I need to use VBA?
Please help!

Access filters on splitform through query to report

I have a splitform and what I want to do is open report on filter I use in this spltiform. What's important is that in this splitform you can do the correction of the row (you can't edit the previous row, but it creates two additional rows - one is negative and the other is to edit and I have one column which stores the ID of corrected row - CorrectedRowID). So I can't create report based on that table, so I created a query which groups this data by CorrectedRowID and it takes the last row of each ID so I have only the newest row of every ID. Then based on that query I created report.
On the splitform I have button which opens the report. But what I want is that when I have filter in this splitform and I click on the button Open Form it opens the report already on the filters. I have used this code in this button in VBA:
Private Sub Command282_Click()
DoCmd.OpenReport "tb_ewid_WNT1_raport", acViewPreview, , Me.filter
End Sub
When I create a normal report (not based on query) filter works great, but when I put some filter on the data in this splitform on one column it asks me for the value of the column on which I want to filter my data.
The query returns the newest rows of each ID. For example:
ID
Name
Quantity
Price
CorrectedRowID
IsCorrection
1
bread
4
1,5
1
No
2
milk
3
2,3
2
No
3
bread
-4
1,5
1
Yes
4
bread
11
1,5
1
Yes
In this case query will return this, so for each CorrectedRowID it returns the highest ID:
ID
Name
Quantity
Price
CorrectedRowID
IsCorrection
2
milk
3
2,3
2
No
4
bread
11
1,5
1
Yes
I created the report based on this query. And I also created a button on splitform which uses the code I wrote up. When I filter my data and when I click on this button it asks me for the value for some column (it's not the same every time). The values that it asks for are combo boxes which take the values from not the same table. The query uses JOIN.
Where did I make mistake?

SSRS insert exact specific value in a cell of a Matrix using expression

I'm not sure if my question is really stupid, but I found nothing on the internet...
Is it possible to insert a specific value in a cell of a matrix?
for example I have a dataset like below:
Month Prod Amount
2 X 34$
11 Y 12$
7 Z 150$
and a matrix like:
-------| Month |
Prduct |SUM(Amount)|
So the row group are products and column group are the months of a specific year.
If I want to add an extra column, with a specific value chosen dynamically from the amount (for xample 150$) so to have
-------| Month |columnName
Prduct |SUM(Amount)| 150
is that possible? also if the value is repeated through the column (it would be useful if I wanted the new column to have this specific value added for each value)
thanks a lot!! :D
You can insert a value directly in your matrix but it will be repeated for each record.
The best way is to add a new column with conditional values is to do this in your dataset query. Probably with a CASE statement if you are using SQL.
EDIT: If you can't adjust the query for whatever reason, you can add the new column and use SWITCH function inside your textbox to achieve the same.

How to combine a row of cells in VBA if certain column values are the same

I have a database where all of the input from the user (through a userform) gets stored. In the database, each column is a different category for the type of data (ex. date, shift, quantity, etc) and the data from the userform input gets put into its corresponding category. For some of the data, all the data is the same except for the quantity. I was wondering how I could combine these rows into one and add the quantities to each other for the whole database (ex. combining the first and third data entries). I have tried playing around with a couple different loops but can't seem to figure anything out.
Period Date Line Shift Type Quantity
4 x 2 4/3/18 A 3 14 18
4 x 2 4/3/18 A 3 13 12
4 x 2 4/3/18 A 3 14 15
Thank you!
If you're looking to modify the underlying database, you might be able to query the data into the format you want by including all the other columns in a GROUP BY statement, save the result to another table, then replace the original table with the properly formatted one.
If you have the data in Excel and you just want to view it with the duplicate rows summed, a Pivot Table would be a good choice. You can select all the other columns as rows for the Pivot Table and sum of Quantity as the values.

Excel VBA data manipulation

My problem might be simple but i have been stuck on it for a while. I have a list of accounts in column B (XXXXXX). Then in column D i have a quantity of contracts traded. In the column E i have the prices of those contracts. The column next to it has the name of the product traded.
The way i get the raw data i sometimes get a trade split in 2 parts. For example i might have on one row for the same (column B) account XXXXXX , QTY(Column D) 2 and Price(column E) 5.23$ and security(column F) NKE. In the next row i have the same account XXXXX , QTY is 3 , Price is same and the security is same. I want something that will loop through the entire data and add the QTY to 5 and keep everything else the same. So at the end i should have one row with with account XXXXXX with QTY 5 Price 5.23$ and Security NKE. I have tried pivot tables but it adds the price of the security to 10.46$ and that messes up calculations. I cannot figure what sort of a macro i should use. Can someone please help. I am posting a picture to help understand the problem. THanks. enter image description here
A pivot should show you what you want. Don't put Price in VALUES. Account, Security and Price can go in ROWS then Sum of Quantity in VALUES. That should give you the breakdown you're after.
Choose the most unique column (probably F).
Filter your data by this column.
Make an infinite loop. Inside the loop:
declare a variable for row number
check if the current row has the same value in column F as the row below
if yes, add quantities in first row and delete second row
if no, add one to row number and check if there is something in the current row. If no, exit the loop.

counting and numbering in a select statement in Access SQL

Could you please help me figuring out how to accomplish the following.
I have a table containing the number of products available between one date and another as per below:
TABLE MyProducts
DateProduct ProductId Quantity Price
26/02/2016 7 2 100
27/02/2016 7 3 100
28/02/2016 7 4 100
I have created a form where users need to select a date range and the number of products they are looking for (in my example, the number of products is going to be 1).
In this example, let's say that a user makes the following selection:
SELECT SUM(MyProducts.Price) As TotalPrice
FROM MyProducts WHERE MyProducts.DateProduct
Between #2/26/2016# And #2/29/2016#-1 AND MyProducts.Quantity>=1
Now the user can see the total amount that 1 product costs: 300
For this date range, however, I want to allow users to select from a combobox also the number of products that they can still buy: if you give a look at the Quantity for this date rate, a user can only buy a maximum of 2 products because 2 is the lowest quantity available is in common for all the dates listed in the query.
First question: how can I feed the combobox with a "1 to 2" list (in this case) considering that 2 is lowest quantity available in common for all the dates queried by this user?
Second question: how can I manage the products that a user has purchased.
Let's say that a user has purchased 1 product within this date range and a second user has purchased for the very same date range the same quantity too (which is 1) for a total of 2 products purchased already in this date range. How can I see that for this date rate and giving this case the number of products actually available are:
DateProduct ProductId Quantity Price
26/02/2016 7 0 100
27/02/2016 7 1 100
28/02/2016 7 2 100
Thank you in advance and please let me know should you need further information.
You could create a table with an integer field counting from 1 to whatever max qty you could expect. Then create a query that will only return rows from your new table up to the min() qty in the MyProducts table. Use that query as the control source of your combobox.
EDIT: You will actually need two queries. The first should be:
SELECT Min(MyProducts.Quantity) AS MinQty FROM MyProducts;
which I called "qryMinimumProductQty". I create the table called "Numbering" with a single integer field called "Sequence". The second query:
SELECT Numbering.Sequence FROM Numbering, qryMinimumProductQty WHERE Numbering.Sequence<=qryMinimumProductQty.MinQty;
AFAIK there is no Access function/feature that will fill in a series of numbers in a combobox control source. You have to build the control source yourself. (Anyone with more VBA experience might have a solution to solve this, but I do not.)
It makes me ache thinking of an entire table with a single integer column only being used for a combobox though. A simpler approach to the combobox would just to show the qty available in a control on your form, give an unbound text box for the user to enter their order qty, and add a validation rule to stop the order and notify them if they have chosen a number greater than the qty on hand. (Just a thought)
As for your second question, I don't really understand what you're looking for either. It sounds like there may be another table of purchases? It should be a simple query to relate MyProducts to Purchases and take the difference between your MyProducts!qty and the Purchases!qty. If you don't have a table to store Purchases, it might be warranted based on my cursory understanding of your system.
