I am trying to figure out how to limit the number of times an ID can be selected.
I have a list of mentors, some who can be selected 1 time and others who can be selected 2 times. I am using a button that performs a Set Field script. When the button is clicked the ID value is copied to another list. It remains in the original list but also is shown in another. I want to say something like:
If field "mentor count" = 2 then You can select 2 times, else you can select 1 time.
I have no idea how to go about it.
Do you have any suggestions please?
There are a total of 3 lists. One is mentors, 1 is students and the other is both. The user selects a mentor and student to match up. Each row in this table is a new match.
I tried conditional action which failed. I am thinking I will need a script.

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?
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.
To the person who posted a macro. Can you please repost? I was just writing a note to you and I see you deleted the comment
I'm trying to create a query that will insert new records to a table or update already existing records, but I'm getting stuck on the filtering and grouping for the criteria I want.
I have two tables: tbl_PartInfo, and dbo_CUST_BOOK_LINE.
I'm want to select from dbo_CUST_BOOK_LINE based upon the combination of CUST_ORDER_ID, CUST_ORDER_LINE_NO, and REVISION_ID. Each customer order can have multiple lines, and each line can have multiple revision. I'm trying to select the unique combinations of each order and it's connected lines, but take the connected information for the row with the highest value in the revision column.
I want to insert/update from dbo_CUST_BOOK_LINE the following columns:
CUST_ORDER_ID
PART_ID
USER_ORDER_QTY
UNIT_PRICE
I want to insert/update them into tbl_PartInfo as the following columns respectively:
JobID
DrawingNumber
Quantity
UnitPrice
So if I have the following rows in dbo_CUST_BOOK_LINE (PART_ID omitted for example)
CUST_ORDER_ID CUST_ORDER_LINE_NO REVISION_ID USER_ORDER_QTY UNIT_PRICE
SCabc 1 1 0 100
SCabc 1 2 4 150
SCabc 1 3 4 125
SCabc 2 3 2 200
SCxyz 1 1 0 0
SCxyz 1 2 3 50
It would return
CUST_ORDER_ID CUST_ORDER_LINE_NO (REVISION_ID) USER_ORDER_QTY UNIT_PRICE
SCabc 1 3 4 125
SCabc 2 3 2 200
SCxyz 1 2 3 50
but with PART_ID included and without REVISION_ID
So far, my code is just for the inset portion as I was trying to get the correct records selected, but I keep getting duplicates of CUST_ORDER_ID and CUST_ORDER_LINE_NO.
INSERT INTO tbl_PartInfo ( JobID, DrawingNumber, Quantity, UnitPrice, ProductFamily, ProductCategory )
SELECT dbo_CUST_BOOK_LINE.CUST_ORDER_ID, dbo_CUST_BOOK_LINE.PART_ID, dbo_CUST_BOOK_LINE.USER_ORDER_QTY, dbo_CUST_BOOK_LINE.UNIT_PRICE, dbo_CUST_BOOK_LINE.CUST_ORDER_LINE_NO, Max(dbo_CUST_BOOK_LINE.REVISION_ID) AS MaxOfREVISION_ID
FROM dbo_CUST_BOOK_LINE, tbl_PartInfo
GROUP BY dbo_CUST_BOOK_LINE.CUST_ORDER_ID, dbo_CUST_BOOK_LINE.PART_ID, dbo_CUST_BOOK_LINE.USER_ORDER_QTY, dbo_CUST_BOOK_LINE.UNIT_PRICE, dbo_CUST_BOOK_LINE.CUST_ORDER_LINE_NO;
This has been far more complicated that anything I've done so far, so any help would be greatly appreciated. Sorry about the long column names, I didn't get to choose them.
I did some research and think I found a way to make it work, but I'm still testing it. Right now I'm using three queries, but it should be easily simplified into two when complete.
The first is an append query that takes the two columns I want to get distinct combo's from and selects them and using "group by," while also selecting max of the revision column. It appends them to another table that I'm using called tbl_TempDrop. This table is only being used right now to reduce the number of results before the next part.
The second is an update query that updates tbl_TempDrop to include all the other columns I wanted by setting the criteria equal to the three selected columns from the first query. This took an EXTREMELY long time to complete when I had 700,000 records to work with, hence the use of the tbl_TempDrop.
The third query is a basic append query that appends the rows of tbl_TempDrop to the end destination, tbl_PartInfo.
All that's left is to run all three in a row.
I didn't want to include the full details of any tables or queries yet until I ensure that it works as desired, and because some of the names are vague since I will be using this method for multiple query searches.
This website helped me a little to make sure I had the basic idea down. http://www.techonthenet.com/access/queries/max_query2_2007.php
Let me know if you see any flaws with the ideology!
I have a column in the sql server called "Ordinal" that is used to indicate the display order of the rows. It starts from 0 and skips 10 for the next row. so we have something like this:
Id Ordinal
1 0
2 20
3 10
It skips 10 because we wanted to be able to move item in between items (based on ordinal) without having to reassign ordinal number for the entire table.
As you can imagine eventually, Ordinal number will need to be reassign somehow for a move in between operation either on surrounding rows or for the entire table as the unused ordinal numbers between the target items are all used up.
Is there any algorithm that I can use to effectively reorder the ordinal number for the move operation taken in the consideration like long term maintainability of the table and minimizing update operations of the table?
You can re-number the sequences using a somewhat complicated UPDATE statement:
UPDATE u
SET u.sequence = 10 * (c.num_below-1)
FROM test u
JOIN (
SELECT t.id, count(*) AS num_below
FROM test t
JOIN test tr ON tr.sequence <= t.sequence
GROUP BY t.id
) c ON c.id=u.id
The idea is to obtain a count of items with the sequence lower than that of the current row, multiply the count by ten, and assign it as the new count.
The content of test before the UPDATE:
ID Sequence
__ ________
1 0
2 10
3 20
4 12
The content of test after the UPDATE:
ID Sequence
__ ________
1 0
2 30
3 10
4 20
Now the sequence numbers are evenly spread again, so you can continue inserting in the middle until you run out of new sequence numbers; then you can re-number again.
Demo.
These won't answer your question directly--I just thought I might suggest some other approaches:
One possibility--don't try to do it by hand. Have your software manage the numbers. If they need re-writing, just save them with new numbers.
a second--use a "Linked List" instead. In each record store the index of the next record you want displayed, then have your code load that directly into a linked list.
Yet another simple approach. Let's say you're inserting a new record with an ordinal equal x.
First, check if there's a row having ordinal value equal x. In case there's one, just update all the records having the ordinal value equal or bigger than x increasing them by y. Then, you are safe to insert a new record.
This way you're sure you'll not run update every time and of course, you'll keep the order.
I have this spreadsheet i am working on for awhile. Its basically attendance piece. End user keeps track of employees, if they showed up or not etc...
I have tired looking up loops but i couldn't figure out how to do what i am trying to do.
What i have in this excel.
A-D : Emp info
E-∞ : 1-3 Days/Dates; 4-∞ emp data (if they missed a day, values for that)
To get better understanding, see this
The data entered from E5 to xx thats where i am trying to get this vba working.
Anything the script detects first value either '1' or '2', start 90 days (cells) from there. And after 90, reset to 0. starting from 91 start search for '1' or '2' and do similar.
See the excel file for better understanding. If it doesn't make sense, ill be happy to simplify.
Thank You
The most efficient and clean way to handle this is to use a form of a relational data model because it can be done easily without using VBA code. You will have two simple tables in your spreadsheet, EmployeeInfo and AttendanceRecords. Your Employee info will look something like this
Emp# Name Craft # In 90 Days NumOf2s NumOf1s
1 EMP 1 SM Site Manager 0 0 0
2 EMP 2 SM Site Manager 1 0 1
3 EMP 3 SM Site Manager 0 0 0
4 EMP 4 SM Site Manager 0 0 0
5 EMP 5 SM Site Manager 1 0 1
The last three columns are calculated from the AttendanceRecords table. This table is going to be variable size but this way you only need to store the important data (When employees actually got marks). It will look like this.
Emp# Date Days Count
1 12/1/2013 122 1
3 1/1/2014 91 2
2 2/1/2014 60 1
5 2/15/2014 46 1
You can have multiple entries for the same day and the same employee. The important thing is that we only need one entry per infraction (NOTE: In order to do this in a proper database type model, each attendance record should also have some kind of incrementing totally unique ID (like employees), but we can forgo that for this application).
You enter in the employee number, the date, and the count. The "Days" column then auto calculates the age of the record with the following formula:
=TODAY()-[#Date]
NOTE: If the [#Date] notation does not look familiar, this is because it deals with Excel Tables. I recommend you read up on those if not already familiar.
So now we have the age of each record. So back on the EmployeeInfo table, we use the following formula to get all AttendanceRecords that apply to Employee x for the last 90 days
=SUMIFS(AttendanceRecords[Count],AttendanceRecords[Emp'#],[#[Emp'#]],AttendanceRecords[Days],"<=90")
You can now also use some simple formulas to get the other columns I pointed out, including the number of 2 count in fractions or the number of 1 count infractions:
=COUNTIFS(AttendanceRecords[Emp'#],[#[Emp'#]],AttendanceRecords[Days],"<=90",AttendanceRecords[Count],2)
=COUNTIFS(AttendanceRecords[Emp'#],[#[Emp'#]],AttendanceRecords[Days],"<=90",AttendanceRecords[Count],1)
There is a lot more data that could be gathered, including the date of the last infraction, total number of infractions for all time, etc. If any of the formulas or terms I used don't make sense or need more explaining, feel free to ask.
EDIT: If you want them automatically removed after 90 days, it would be relatively easy to write a VBA script to do this. It would also be easy to just sort the AttendanceRecords table on Days and delete all records that are older than a certain number of days. However, unless you see yourself adding hundreds of records a week, this really shouldn't be necessary. Also, If you want to write a Visual Basic form to enter in new infractions, that is definitely very possible, but another discussion.
EDIT: To respond to concerns about viewing when these issues happened, I will give you an example of a way to view the data in your tables. One of the advantages of excel tables is that the order of the records isn't as absolute as in a normal range, so we can sort, rearrange, and filter them to see what we need. So if you need to see all of the issues with employee 3, you just go to the Emp# column in the AttendanceRecords table, select the little arrow down button next to Emp#, uncheck 'Select All', and then check the '3', and then the only values I will see in the table are the ones from employee 3. I can then sort the 'Date' column by clicking its little arrow and selecting 'Sort Newest to Oldest'.
What it comes down to is that you can view ANY data you need to, and if you think through what you really need to see, you can set up your summary table (EmployeeInfo) to display enough data that you hardly ever have to look at the AttendanceRecords table. But if you need to, you can go into that table and do a manual sort (as I described above) very easily.
EDIT: To help add some of the functionality I've shown above to the askers current spreadsheet, I will show the current formula.
=SUMIFS($E5:$BR5,$E$3:$BR$3,">"&(TODAY()-90))
For EMP 1, this formula uses the employees row as the sum range. It then looks at the field of dates in the corresponding columns in row 3. If the date in row 3 is > TODAY()-90, then we will add it to the count. This will at least just look at the infractions for the previous 90 days.
