Limit Number Of Results
Jul 29, 2005
I am designing a database for a marketing company. One of my tables has all of the company's contacts. On the contacts form, I have a button that opens up a query that shows the information for the company that contact works for. I have a problem where if I have more than one contact per company, it will return that many results (which is just a repeated list of the same company information). It is an eyesore to look at the same information in two or more rows, so I was wondering, can I make the query return only one result? I've been looking online, and I haven't found this at all. Thanks a lot.

I'm currently trying to create a KPI report (Key Performance Indicator) to log jobs & their response times
I can easily produce a query that gathers all the information needed but I need to find a way to limit the results to 1 record per job as one job can have many records - Primary key being the TaskID field
I need a way to only pick out the oldest record & ignore the rest
For example
A priority 1 job that was logged at 01/05/2008 08:00 that needs to be responded to within 2 hours
Two engineers have carried out the work & logged the following details
1st Engineer responded at 01/05/2008 09:00 and the other returned later to complete the job at 01/05/2008 13:45
I need the query to only pick out the entry for 01/05/2008 09:00 as it's the oldest.
Any suggestions would be most welcome
this is what my query looks like at the moment.
SELECT tblTasks.TaskID, tblTasks.DateReported, DateAdd("h",DLookUp("[ResponceTime]","[tblPriorities]","[tblPriorities]![PrID]=" & [PrID]),[DateReported]) AS DueBY, tblTaskTime.TTStarted AS DateStarted, tblPriorities.Priority, tblPriorities.ResponceTime, [DateStarted]-[DateReported] AS Responded
FROM tblBuildings INNER JOIN (tblContracts INNER JOIN (tblPriorities INNER JOIN (tblTasks INNER JOIN tblTaskTime ON tblTasks.TaskID = tblTaskTime.TTLINKTask) ON tblPriorities.PrID = tblTasks.TaskPriority) ON tblContracts.ContID = tblTasks.ContractNo) ON tblBuildings.ProID = tblTasks.BuildingID
WHERE (((tblPriorities.Priority) Not Like "P8*" And (tblPriorities.Priority) Not Like "P5*" And (tblPriorities.Priority) Not Like "P3*" And (tblPriorities.Priority) Not Like "P6*"))
ORDER BY tblTaskTime.TTStarted;
Thanks

I have an unbound form with a subform which is bound to a query. The subform prioritizes and individually lists all projects my company has on its agenda and the project’s corresponding cost. Is it possible to enter a dollar figure (which would represent our budget) on the main form and have the subform list only the top prioritized projects whose running total costs would fit within the budget figure stated? Any help would be appreciated as I don’t even know if this is possible. Thanks.

I am querying a linked ODBC table with a date column called "db_created_tms" that has dates in formatted like "2/25/2004 8:54:02 PM" , because it is a linked table I can't edit the data type. How can I limit my query results to the last 30 days.
My query without the date limit currently looks like this:
SELECT QBReportAdminGroup_v_txn_po_line.doc_num_h AS po, QBReportAdminGroup_v_txn_po_line.quantity_qnty AS qty, QBReportAdminGroup_v_lst_item.name AS REFERENCE, QBReportAdminGroup_v_txn_po_line.unit_price_amt AS cost, QBReportAdminGroup_v_lst_vendorODBC.name AS vendor, "" AS LOCATION
FROM (QBReportAdminGroup_v_txn_po_line INNER JOIN QBReportAdminGroup_v_lst_item ON QBReportAdminGroup_v_txn_po_line.item_id = QBReportAdminGroup_v_lst_item.id) INNER JOIN QBReportAdminGroup_v_lst_vendorODBC ON QBReportAdminGroup_v_txn_po_line.vendor_id = QBReportAdminGroup_v_lst_vendorODBC.id;

Essentially I have a table for rooms around my school and what the rooms contain. Most of the details for the rooms are Boolean (e.g. If the room has a projector, Yes/No). So what im trying to do is have a form where i can select a checkbox(s) and if i tick one, a query that holds all the room details will only show rooms with projectors in them, which i can then display those results in another form.
My question is how do I get the check boxes in the form to narrow down the room results to only show the ones with the criteria i have selected in the form?

I have a table that has several fields including CallID (autonumber) and SKU (text)
SKU can be anything up to 9 characters, sometimes numeric sometimes alphanumeric. For example: 24300, AA23145, G58d444, 24999, 89332,...
Based on the Count of CallID I can easily get the top20 calls on each SKU. This is the query I use for that:
Code:
SELECT TOP 20 Count(Calls.CallID) AS CountOfCallID, Calls.SKU
FROM Calls
GROUP BY Calls.SKU
HAVING ((Not (Calls.SKU) Is Null))
ORDER BY Count(Calls.CallID) DESC;
The problem is that now I have been asked to create two different lists. One that has the top 20 SKU that range from 24520 and 24599 and another one that does the res tof the SKUs.
Obviously my problem is that the SKU field is text, not numbers so I can't just limit the results in the query by using "Between 24520 and 24500" in the query criteria.

I have a DB with 4 tables:
Property (used for look-up values)
Service Type (used for look-up values)
Rate Table (uses the Property Table and Service Type Table and is used as a rate look-up table for the daily service table noted below)
Daily Service
Using the Daily Service table, I need to choose a property, choose a service type that is limited to the property (100's of service types, but a property may only have a limited number), and enter a quantity, and have the Rate Table return the specific cost of the service. I didn't think this was too hard in Access (2013), but I seem to be hitting a wall and spending too much time figuring it out. Now I am behind in my project.
I have been trying to do this in a table format, but have been unsuccessful in limiting the results of the Service Type combo box based on the property chosen.

Hi,
I have searched for an answer to this question a lot, but I could not find it. I hope anyone can help me with the following:
I need to do a database in MS Access; however, there is so much information and some of it is not related. After normalising it, it looks like I need a number of tables. Is there a limit to how many tables you can have on Access? And how many tables is the recommended size?
Any help will be very much appreciated.

Is there a limit on the number of records you can have in an access database? I've got one with 8500 records and it's been a PITA! I have a webpage on our intranet so users can go and enter their information to it, and they get a nasty error whenever they try to enter information. I'm trying to figure out why and i was just wondering... i know it's not the webpage because when i connect it to my test database it works fine? so i dunno :confused:
any help is greatly appreciated!!

Hi All.
Is it possible to limit the number of records in a form, to a number given in a linked form.
For Example.
tblA
StreetName
No_Of_Houses
tblB
Name
Number
I would only want the number of records in tblB to be the same as No_Of_Houses in tblA.
I have seen previous threads where you can limit it to a number, but do not know where to go from there.
Can anyone help?
Thanks.
Frank.

HeyI'm trying to create a Library database. This involves restricting the number of loans available to each member (currently 3). I need to make it so no more than 3 records exist in that table for each member. For now ive just entered a VB script that has a message box saying not to enter more than 3 loans per person but I dont think thatll be enough, I need some sort of validation for the whole table rather than a field.I know how to limit the returns of sql queries which is all I can find, but not how to limit the actual amount of entries. The loan table is part of a double query within a subform of the member form if it helps :s

Hi guys,
I have a text box, which requires a 8-digit number entry. I have wrote the code to check that the length is 8 and if it isn't a label will turn visible next to the field telling the user entry must be 8 digits.
This works for when i enter a number less than 8-digits but when i input a number with more digits as it does not fit into the text box it turns it to a scientific format value and when the code runs it shows the length is actually 8! And therefore the entry is valid!
I.e. when i input 123456789 the text box shows 1.23E+08 which is 8 charecters!
I dont want any error messages to pop up as i handle them by code and use labels to show the error message next to the problem field and i would like to keep this consistent. Is there any way i can do this by a function or a property in the table or form?
I appreciate any help/advice
cheers

I am new to Access and I am developing a form. I have already read and found useful resources on internet but there is something I am not able to sort out.I have seen that the limit of fields I can enter in Access is 255 and my survey is far below that number.So no issue at all when I created the fields in Data view.However, the issues started when I created a form.
I created a form by Create>Form.The last few fields, at the very bottom of the form, are squeezed onto each other as if there was not any space available. Is there a limit to the number of fields I can have in a form? There should not be if I am allowed to enter up to 255 fields. How can I go about it? Should I alternatively create 2 forms? I would rather not to though.

building a validation expression that concerns four of my fields:
Quote:
Country | Text
Centr | Boolean
Centr limit | Integer
Apply | Boolean
The number of records that have the same country, AND Centr=TRUE, AND Apply=TRUE, should not exceed the Centr limit value.

Hi all, I've searched this with no success.
I have a ODBC (Firebird) table linked using a DSN connection which has >300 fields. In Access, the linked table only show 256 fields (max for Access). Otherwise the link works fine. I have no control over the source Firebird table.
What I'd like to do is limit which fields from the Firebird table are shown in Access. I don't need all the fields, but I need some that are at the end and are not linked in the current setup.
I'm very much a novice at using ODBC, but can I somehow use SQL or some other method to specify which fields to show in the linked table?
Thanks for any suggestions,
John

Ok, not sure if this is even possible or where to even start..
I've got a form that has all the info for a client, eg..
Client First Name
Client Last Name
Client Hours
Client WE/CS/EE
Client Day And Times
Client Phone
Client Comments
Begin Date & End Date (2 boxs) on there for date input..
and what i'm trying to do is limit that any date entered between begin date and end date, it'll check and make sure there is only ever 20 clients on any 1 day..
i thought Datediff would be the way to go, but then again how do you get it to search each day and make sure theres only 20 clients on there..

Is it possible (without using VB) to limit the number of selections a user can make in a multiple value list?
My list is one a form and when in the form field it brings up a total of 15 names with checkboxes, allowing you to "check" each name you want. However, I want to be able to have as many names as I need in the list, but limit the user to selecting only two of them.
