We need a query in which for each student is allowed to preset a limited number of lectures on a specific subject. For example each student can provide only two lectures on a subject and any more lectures on the same subject presented by him will not be counted. In the above example records 7 8 9 and 11 will not be shown in the query.

I Have Created A Client Reference Allocation Screen Which Makes The Clients Reference From Details In A Number Of Text Boxes.
For Example:
Client Number: 0010, Forename: Andrew, Surname: Bloggs, Year: 2007,
Occupation: Driver.
Client Reference = 0010ab-dr07
I Have Copied The Text Boxes So The Information Is Automatically Displayed To Create The Client Reference, But Rather Than Shortening The Copied Text Boxes To Show Only The First Few Characters Is There A Way Of Limiting The Number Of Characters Shown In The Copied Text Boxes??

I would like to limit the number of users connected to a shared database. Each user opens a database as the default 'Admin' user. Does anyone know how to do that without user authentication? What event occurs when a user opens the database? How to supervise the ldb file that manages shared usage? I suppose it should be something with the Workspace object.
Any ideas?
Show me the door, please :-)

I have a field in the parent table which indicates how many child tables there should be at the most. I'm uncertain about how to enforce this. I"m using access as the database to a Vb.net app. Should I do it in access or Vb.net or both.

During a promotion we are running the customers are only allowed 3 entries into the system per day but the users are occasionally putting some customers in more than that. I could use some kind of function that limits the number of times the account number can be put in on a given date. (Or daily)
I have the following text boxes: ID, Customer first name, customer last name, account number, date, time.
Any ideas please?

I'm trying to create an Access database for my college so that our call centre can allocate students to a specific interview time/date. The problem I'm having is that each interview slot must only have a maximum of 10 students at a time.
I'm creating tables for the student details, address and for each interview slot available.
I'm using Access 2010.
How I can limit the number of records in a table to 10 so that when that interview slot is full it informs the user?

Well boys and girls, its about that time in the week where I have once again come up with a brilliant application for my little Access project, but have no idea how to make it happen.
I will start with a little background info... In the course of the parts recoveries we have different reasons for recovering parts, different people (locations) that request them, and different priorities for recoveries. For example, when a new model comes out, we will recover 100% of the parts for investigation by the factory... however, we may want to take a look at failed water pumps first. In this case, our recovery, until it is complete, will have higher priority than the 100%, otherwise we would not receive any parts.
This is because of the way our warranty system works... It assignes a three digit number to each part number of a recovery (between 1-999). The lower the number, the higher the priority.
So if I am setting up a 100% recovery, I would want to put it in the, say, 200's. This would leave room for an overlapping recovery to be inserted in the 100's where it would divert a certain number of parts away from the normal recovery stream. Then, once a user-defined date or quantity of parts has been reached, the corresponding number goes dead, and any of those part numbers are reunited with the original recovery stream.
Sticking to the example above, typically 100% recoveries would go for say... 2-3 years, where as an in-house recovery might be for 20 parts... Another difference is that the longer term recoveries are managed by the end date, where shorter term recoveries are by number of parts recieved.
What I want to do is be able to auto assign these numbers based on criteria derived from user-inputted data... (i.e. destination, start/end date, recovery type, etc.). Then, when the recovery is complete, whether based on date or quantity recieved, to delete the information associated with the 3 digit number, block its use for 45 days, and then be able to reuse the number for a new recovery.
Whew.
Thanks to anyone who can be bothered to read past the first paragraph, let alone offer any advice.

Hello,
i have tried to find an answer but can't seem to find any posts that apply.
I need to limit the records returned in a query to 3. Well, that is fine, i have set it to do the top 3, and it is working well, I am looking at the top percentages received in a number of criteria. However we have just discovered a situation where someone has 7 all with 100%, so all 7 records are being returned. I can see why, i just don't want them to be!
The report based on the query requires only three records, in this case we don't care which 3, seeing as they are all equally good, in fact randomness is a boon.
Any ideas out there - i 'm stumped!

Hello again my forum o' saviours, Current filter: WHERE (Assignments.[AcademicYear]) Like ([Please Enter Academic Year])AcademicYear is a field in the Assignments table (duh). In this same query, I have a couple fields (equations and if/thens built on the assignments table) that will need to be used as further filters. I thought something like WHERE ((Assignments.[AcademicYear]) Like ([Please Enter Academic Year]) )& (len([groupwinterbox])+len([groupspringbox])+len([groupfallbox]) > 3) would work, but I keep getting pop-ups asking what the values of the three query-based calculations are. Where did this noob screw up?

I'm trying to filter the options in a combo box based on two criteria. The first criterion is another combo box on the same form, for a cascading combo effect. This criterion works fine, no problems at all. The second criterion is a query. So the combo box should display only those values that match both the upstream combobox AND the results of the query. What's really frustrating is that this combobox works just fine in my development dbase. It only stops working when I move it into my active dbase. Anyway, here's the SQL for the combobox rowsource:
SELECT DISTINCT Size2.SizeID, Size2.XYdim
FROM (Shapes INNER JOIN (qrySignsInInventory INNER JOIN Size2 ON qrySignsInInventory.SizeID = Size2.SizeID) ON Shapes.ShapeID = Size2.ShapeID) INNER JOIN Signs ON Shapes.ShapeID = Signs.ShapeID
WHERE (((Size2.SizeID)=[qrySignsInInventory].[SizeID]) AND ((Size2.ShapeID)=(SELECT Signs.ShapeID FROM Signs WHERE Signs.SignID = [Forms]![frmUsedDropdown]![cmbSignID])));
I've hilighted the criterion that isn't working. Also, I'm not getting any errors or anything, it's just that the results aren't being filtered. I've triple-checked the references for the active dbase, and I've checked the results of the query. Everything should be working.

I have a linked table to Access 2010 which contains tracking numbers for shipments.When I link the spreadsheet to the Table, the FedEx tracking numbers are changed to for example - 9.813842152e+014 instead of 981384215196229. Is there anyway to change these back to its original format? I was thinking of creating a query where I could use Conversion Function, but it kept giving me error. Please note that both the UPS Tracking and FedEx tracking are in the same field.

I don't know why is it so complicated to add an auto number field in a query. I would like to add a increment number (auto number) on each line and then an auto number on each product.

If I have a table called "Calls" with an autonumber and another field with names for stores like this:
1 Hobby Mart
2 Peter's Store
3 Hobby lobby
4 Hobby Mart
5 Peter's Store
How can I build a query to count the number of different store names?
For example, in this case I need the query to return the number 3.

We have a large database table [PRODUCT] with the following fields PROPNUM and P_Date and GAS. We need to normalize the GAS field to the first month of production based on P_Date and sequential months following to average the data. We believe the easiest way is to create a sequential number for each Key PROPNUM that represents the first month of GAS the second month of GAS etc.
We have followed several of the posts on how to sequentially number records, but are struggling to get them to work.The latest effort was to use the make a table query creating an expression with the following.
DCount("*","PRODUCT","[PROPNUM]=" & [PROPNUM] & " AND[P_DATE]<=#" & Format([P_DATE],"mm/dd/yyyy") & "#")

I analyse things by the date they are ordered by the office.
The date gets put into a spreadsheet and i import this into access for the querying.
I need to summarise it by weeknumber and year.
I use the following queries:
To get the week: Week Number: DatePart("ww",[DateOrdered],0,2)
To get the year: Year: Year([DateOrdered])
To put it together: Weekyear: [Year] & "_" & [Week Number]
The problem is when the year changes.
The dates for week 1 for 2014 are between 30/12/2013 and 05/01/2014 and therefore straddles 2013 and 2014.
Therefore when the year and week number is put together the following results are given for that particular week:
DateOrdered - Result of above query
30/12/2013 - 2013_1
31/12/2013 - 2013_1
01/01/2014 - 2014_1
02/01/2014 - 2014_1
03/01/2014 - 2014_1
04/01/2014 - 2014_1
05/01/2014 - 2014_1
All of the above should all read 2014_1 but some obviously are 2013_1. This causes me problems when doing further analysis and cross tabulations.
How can I amend my query so that the above all show the correct year and week number: 2014_1 ?

I need to find the latest number using a query.
All of the numbers follow this format:
[Doc No]
ABCD123
but the tricky part is the number could be suffixed with a revision. It is the latest revision I would like to find. For example, If I have a number followed by 3 revisions I would have:
[Doc No]
ABCD123
ABCD123+200
ABCD123+300
ABCD123+400
I need a query to give me the latest revision, in this case
[Doc No]
ABCD123+400
There is a possibility there are no revisions in which case the latest will be
[Doc No]
ABCD123.
How is this possible in a query???

I have an excel data file that is updated monthly (and I am not able to have the source file format changed of course) that will be my linked table for Access 2007. The file reports monthly data and adds the new month to the right of the historic in a layout like this:
Tree | Orchard | Province | Jan % red | Jan % green | # Limbs | Feb % red | Feb % green... etc so each month it adds 3 new fields to the data.
I have queries (rightly or wrongly) that will calculate the number of apples that month and report on those higher than a certain percentage. I would like to do this without having to create a static table to append to each month as the new data file will always show the full YTD results anyway (and I don't like to store data in my database).
I have a query that counts the number of fields in the raw data file and am wondering if there is a way to have access only run the number of queries required based on the number of fields. i.e. if 11 fields then run queries 1 thru 5, if 14 run 1 thru 6 etc.

I have 2 tables: Table A contains [ID] (and other columns) AND Table B contains [Request ID] (and other columns).
However, [Request ID] contains several number separated by comma. For example: 10, 15, 20 etc.
I created a query with parameter with : Like "*" & [ID] & "*" under [Request ID] criteria.
Here is my problem:
if [Request ID] = 44, 60 then it is returning [ID] 4 records (4, 6, 44, & 60). Is there a way to show only 2 records? 44 & 60?

I have a query which runs fine, however one of the outputs is a calculated field and i use the Format(someValue,"Fixed") method of specifying the format for the % Change .Here is the query
Code:
SELECT tblTempBearsWeek3.SymbolCode AS [Short Ticker], tblTempBullsWeek3.SymbolCode AS [Long Ticker], tblTempBearsWeek3.[Week 3 Date], tblTempBearsWeek3.Short, tblTempBullsWeek3.Long, tblTempBearsWeek3.[Short Week 3 Close], tblTempBullsWeek3.[Long Week 3 Close],
[code]...
The problem is that the % Change calculated field for some reason comes out as a String. i know this because when I try and sort on that column, it sorts it as if it is text and not a number value i.e. it doesn't put it in Ascending order.
