Restrict Number Of Table Entries?
May 13, 2005
Hey all,
I'm having a horrible time trying to get this to work. Basically, I have a database which has multiple tables. All of my tables are being generated with a CREATE TABLE statement. What I would like to do is add a validation rule or something else upon creation so that only X number of entries can be entered into the table.
Initially, I just added a rule that said id<5 or whatever manually to the table in order to restrict the number of entries, but I can't figure out how to do this automatically in my SQL statement or Visual basic. I want to be able to have this check added upon table creation. Surely what I'm doing must be possible.
Am I going about it the wrong way? Any Help would be appreciated. Thanks!

I would like to know if there is any procedure to restrict/stop auto number increment for certain number of record count (say 50), then increment by 1 for next 50 records.

I have a form (called User_Input)with 2 text boxes, 5 combo boxes and a Submit button, which is bound to a table (called Submssion table) i.e the form submits its entries into the table called Submission.
I want the submit button on the form to work based on this condition:
1. Check current submission of four fields (corresponding to entries from 4 out of the 5 combo boxes on the form) in the table and confirm if the current selection on the form already occurs in the table up to two times. If this is the case, the Message Box should pop up on the form informing user to make another selection as maximum number of entries for that particular selection is already in the Submission table.
2. The checks for the four fields will be done simultaneously as the selection will be done together on the same form.
3. However, if the entries on the Submission table is not up to 2, the entries should be saved to the table and Messagebox should display "Thank you for your Submission"
I need to use Macros for this being a web database which will be published using Sharepoint and VB is incompatible with the web database.

I have a database that has 2 tables. Table A and Table B. Table A is my primary table. On this table I have 2 fields. The first field is a LOOKUP Field that looks up information from Table B and displays my selection in the field on Table A. Then using DLOOKUP I automatically input the information in the Second Field on Table A based upon the selection from the First Field.
This is working mostly correctly. However, the problem is, when I click on the next record in the table, it automatically changes the Second Field on that record to the same value as the record before it and continues this trend each time I click on another record. This occurs without me making a selection in the first field. If I make a selection in the first field it does change the Second Field to the Correct Value, but then the next Record has the same issue.
How do I go about fixing this so it doesn't change the value with the change of the record. Only change if I change that particular field within that 1 record?is there a way to restrict the Value's in my lookup field to only include the Values from Table B that aren't already in Table A?

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...
here's a good one...
I have created a database which allows people to enter in when they are off sick. They have to enter in the FIRST DAY of sickness and the LAST DAY of sickness. All of this information is stored in one big table - SICKNESS TABLE. There are no other date fields in that table.
I want to know how many people have been off for 5 TIMES OR MORE in a 365 day period (which may be say, from Oct 2005 to Nov 2006 - so not always in the same year).
I have managed to get a query that will count the number of times someone has been off; but that could be over, for example, 2 years.
How can I get it to tell me if someone has been off for 5 TIMES OR MORE in a 365 day period???
Thanks
Maria

I'm trying to use access to identify how many times an indiviual appears in my database. I've got a large file which gives me all referrals, each referral comes with two identifiers, one unique to the person, another unique to the referral. This means that the person unique number may be repeated multiple times (if a person has more than one referral) but the referral number would be different each time.
I've run a query to identify the duplicates, i.e. the records where the person unique identifier is repeated. What I am trying to do is work out now how many people have been referred twice, how many three times etc. The original query looks something like this (but on a much bigger scale).
Person Referral
1 A
1 B
1 C
2 D
2 E
3 F
3 G
3 H
What I'm after is a query that will tell me that two people were referred three times (1 and 3) and that one was referred twice (2) and so on.
I'm on Access 2010 if it makes any difference.

Hi, am sure this is simple....! Can't find a solution.
I have records which have YEAR and APPARATUS as two of the fields. All I want to do is write a query which displays all the records chronologically by YEAR then within each YEAR to group them by the biggest subset according to APPARARTUS.
Therefore if there were 20 people who used Motorised equipment, 15 who used electrical and 10 who used gas, the records would be grouped in that order. Thus showing the pattern in change in use of specific apparatus over the years.
Why can't I DO THIS!!??

I am currently trying to figure out how to limit the entries into a nested sub form to just one.
for example im making wine collection database, I have a PURCHASE table, a WINE table containing the FK of the PURCHASE PK, and an INVENTORY contain the FK of the WINE PK.
a purchase can contain many wines, but one wine can only be in one inventory location.
I am trying to add all this information with one form. I fill out the purchase details, enter the info of X bottles of wine were in the purchase, and then with one of those wines selected in their subform, i enter the inventory details for that wine. I go select the next wine in the first subform and the inventory nested subform doesnt allow another entry.
I have this code loaded into the On Current event for the main form:
Private Sub Form_Current()
With Me![INVENTORY Subform].Form
If .Recordset.RecordCount = 0 Then
.AllowAdditions = True
[Code] ....

My problem is the following: when I receive say 5 computers in a purchase form, I want to register the serial number of each of them in another form, bound to another table.If I receive 2 units in the purchase form, my user should only be able to input 2 records in the serial form (a continuous form), if we receive 3, then only 3 records,I cannot quite figure out how to build this second (serial number registration form), so that it refuses input after the correct number has been reached.

I've got a table tblPatienten, a table tblRechnung and a form frmRechnung.
The primary key in tblPatienten is KundenNummer, the primary key in tblRechnung is RechnungsNummer. The relationship between tblPatienten and tblRechnung is one to many.
Now, every patient (stored in tblPatienten) is allowed to make multiple orders (stored in tblRechnung).
How can I assign each new order entry in frmRechnung to an existing patient in tblPatienten?

I have one main table with a list of equipment. I have a second table where there will be a form for damage reports.
What is the easiest way to make multiple entries from the second table correspond with a single entry on the main table?
Some equipment pieces might have dozens of damage reports, while some might not have any.

So I have 2 tables, the first is for "open" orders (where entries get edited changed and deleted), and the Second is for "finished" orders (where once an order is completed it should move from the open orders table to the finshed one where it will no change and will remain for futre reference)
I need help with the transfering part of this problem. I would ideally like to make a form that allows you to pull up the info for the open order then edit it to finally add the finished order to the other table. Im not sure where to start on this one.

Hello,
I have a table which identifies my database users with the following fields:
INITIALS
USER
TITLE
I than have another table named MASTER with two fields named USER and TITLE. The field user, get it's data from the first table INITIALS. I would like that the field TITLE would be updated with the users TITLE once it is entered.
I know how to do this with a form (I place in a txt box =[USER].[Column](2) but have noticed that it only displays the info but not actually stores it into the field.
Is there a way I can do this directly from the table so that I can remove the TITLE control from my form? Thanks.

I have an Access2007/SQL Server 2012 system with 20 users for an insurance company. The company does most of its business via a network of vehicle dealers around the country. If someone comes in to buy a motorcycle, boat, or recreational vehicle at a dealership they need insurance to take it home, and our dealers send the quotes to us.
The dealers, in turn, receive payment from us each month for their efforts. Some are paid a % commission on the premium, some are paid for each quote they send regardless of whether the policy actually sells or not, and some are paid a set amount per sold policy. (Yes, that is relevant information!)
We already have reports that tally the amounts due each dealer based on their payment scheme, but last month our bookkeeper had to write about 650 checks manually because the check writing is not automated. She'd look at the report, and then enter name, address, and amount (in digits and words) into Quick Books and print the checks from there, a horribly tedious process. I've been asked to print the checks from Access. Basically one click would print all 650 checks.
I've opted to use a Make Table query to move the commissioned dealers amounts to a single location, and then to run two append queries to add the records from those paid per quote and those paid per policy. At the end of the day, one table contains all the information necessary to print the checks...except one.
The check number.
I need a way to sequentially number each record in the new table with a user generated starting point, the first check number.
By the way, the check blanks are on standard letter sized paper, three to a page, with tear-off perforations to separate them, in case that information has any relevance.
I think the best way to accomplish this is from the report itself. I've created a blank field on each record for the check number, and what seems most logical is that the sequential number is generated on print and written back to the table, rather than just generating all the numbers at once. That way, should print ever be interrupted, it will be easy to take up where we left off.

Hi All,
I am wanting to build a table which consists of all the queries and tables in the database.
I am expecting column 1 to have all the queries and column 2 to contain all the tables that make up the query. So the table will look like this:
Queries - Linked Tables
Query1 - Table1
Query2 - Table1
Query2 - Table2
Query3 - Table1
Query3 - Table4
As you can see a table can be linked to any number of tables.
Now for my actual question. I don't want to have to type in all the queries and tables. I would like to choose any query and table from a drop down of all possible queries and tables that are currently in the database - like a list, where the list contains all the possible values.
I would then select the relevant entry.
Any pointers would be great.
Thanks,
Evan

Hi all
I'd be very thankful if someone can please help me with this problem.
I have 1 Table. This Table is imported and contains data from Excel. It also contains fields I added manually. There is about 20 imported fields (full of data) and about 100 manually added fields.
Then I made a Query of this table. I made some calculations in this Query.
I then created a Form based on the Query. I then made a Combo Box. This Combo Box selects a customer, and then updates the other fields (the ones I imported from Excel) depending on the customer I selected.
So now what I want to do is this: I want the fields (updated from the query) and newly entered data to save to another newly-created table. Can someone please help me with this? Any ideas?
Thanks a lot. All input greatly appreciated.
