I am creating a database for the local arts centre here is my question
we have several venues each with a limited capacity i am trying to create a booking system so when a venue is selected it checks for capacity at the venue. This is a one off event with one event being held at each venue so it does not need to take into acount dates just free capacity at a venue. Help
Hi everyone,
Hopefully someone can help me.
In Table 1 - I have a set of contracts that have a unique number. However, although the primary key is the contract number - these numbers can be duplicated as long as their start and end dates don't overlap. So my question is, how do I make the Primary key the contract number plus the start and end date? Is this possible?
I know I can select multiple fields for the primary key, but this has a problem...
Here are 3 examples of how Table 1 could be constructed and the Table outline...
Table 1
Field 1: Contract Number
Field 2: Contract Start
Field 3: Contract End
Field 4: Contract Details
Records
Contract Number/Contract Start/Contract End/Contract Details
001/01-Apr-07/31-May-07/Items Cost £1
001/01-Jun-07/31-Jul-07/Items Cost £2
001/01-May-07/30-Jun-07/Items Cost £1
Now, if I select Contract Number/Contract Start/Contract End as the primary fields, the above would not create any conflicts. However, the third record overlaps the first two records date barriers - and I don't want that to be possible.
Any new record's start date MUST be after any existing record with the same Contract Number's End Date. Also, any new record's end date MUST be before any existing record with the same Contract Number's Start Date.
In Table 2 - I have a list of orders that relate to Table 1. i.e. Each order has a contract it relates to. How do I make sure that in a query, the order number picks up the correct contract for the corresponding date.
For example...
Table 1
Field 1: Contract Number
Field 2: Contract Start
Field 3: Contract End
Field 4: Contract Details
Table 2
Field 1: Order Number
Field 2: Order Date
Field 3: Contract Number
My query would pick up Order Number, Order Date, Contract Number, Contract Details.
I think what I'm looking for is validations in the fields. But I'm not entirely sure how to implement those.
I hope I'm making sense...
Thanks again for any assistance,
Ross
I’m trying to do something which should be very simple, I’ve added a new field to a table, but for some reason it won’t update the field when using the form. It’s quite a complex form and my Access abilities are limited so I would rather not create the form from scratch.
I’m trying to create a query that displays only entry’s which contain my new field. However since I have the above problem it doesn’t seem possible.
One way I see around this would be to create a rule in my query where only records were shown when the fields “price” divided by “number_of_players” = 12.5
Can someone please tell me how to write this validation into a query?
Many Thanks
Chris
I'm making a database with 50 fields for the shops of my company. Among these fields, the data of 20 fields must be submitted to us (head office). The data of the remaining 30 fields (like customer address) is just for generating receipts.
At the begining, I set the validation rule of that 20 fields to be "Is not null" in the Form. If the required data (20 fields) is not entered, messages will appear and the record cannot be saved. Then I use the Query function to extract that 20 fields. However, our staff said they might not be able to obtain the information of the 20 fields in the first time. The customers may send them the info later on. So, it not good for me to set any validation rule in the Form.
I would like to ask how I can ensure they submit the data of the 20 fields if I release all the restrictions in the Form? Could I set any validation in the Query so that error message will appear if not all the required fields are filled?
Thank you.
Hi - I have an inventory management database allowing stock to be moved between various subinventories. The user choose a transaction type and then details which goods to move. However at the moment they could enter a Quantity that is greater than that available in that subinventory.
So I have a query that gives me:
Part#
Subinventory
OnHandQty
The data entry form has a control source directly to the Inventory Table. I want to compare a text field [Qty] on a new inventory transaction (the person already having selected Part# / SubInventory from combo boxes) to the On Hand Qty.
I have tried Expression Builder in the Field Validation Property and I have tried some sql code on the AfterUpdate of the text box. I'm just not getting it.
Any help appreciated.
Cheers,
Darren
just woundering wheather you can enter a rule in textbox properties to check the data entered is equal to any of the data in a field in a select table.
Is this possible? If so can you give me an example how?
the table i will be check is "deliveries" and the field will be "driver code no"
i know its possible in vb but im not after that.
hope you can help
Thanks

I have a textbox on a subform to allow a delivery qty to be entered (to allow me to cater for part deliveries). I have a query which totals up the values of this field (so that I have a total of all the deliveries for this record) and compares that value against another field (to check that the total deliveries I have entered do not total more than the ordered qty). I am using this query within the "Validation Rule" of the textbox. My problem is that when I enter the values for the first time this works fine because the figures are not yet part of the query and therefore the check works fine, however if I try to modify a figure I've already entered it triggers the validation each time because it tries to add the new value to the query total.
View 3 Replies View RelatedI'm new to access so I thought this would be easier than it is. I have a list of cities in a simple table . I want use this list (or a query of it) to create a validation rule for a field in a second table "City". How, either with VBA or some other method do I use the Cities database to validate entry. These tables are both in the same project.
Any help is appreciated.
I'm trying to create an Append Query in Microsoft Access to add some data from one table into another table. I checked all of the properties and fields to make sure there are no validations. I have allowed zero length, and have tested the validation rules under the tools section of the design tab on both of the tables. When I run the Append Query, I still get an error that says 0 records added due to validation rule violations.

Hello!
Can someone tell me how to do a validation. The one I am trying to do is check Track No is not duplicated.

Can someone help me please!
Thanks
Hey peeps,
I have a problem. I want my field to become "[field], An " etc. when I type "An [field]" For example, if I type "The Hundred Years War" for the field, it automatically updates to "Hundred Years War, The". I would be happy with a simple validation rule that prohibits the use of "The, A or An" in the beginning of the field but i don't think that is posibble. If this requires VB, I don't know how to use the language and never worked with it. I am completely a novice in VB, but would still love to learn how to make it. :) If you could start me out then, I would appreciate it greatly. :D
Hi im new round here but am working on a database and sum of the validation rules are confusing me now.
Ok i got a couple of things to ask:
1) What rule do i use to make sure only text is entered into the field, i cant use input masks as the size of the text put into the field will vary, as its names of people.
2) Is there a way to check that all the fields on a form have been entered? So if there not all entered an error appears?
3) Finally, is there a way to reset Autonumbers? or do i have to delete all the records and start frm scratch as my autonumbers have gone abiit crazy as sum records have been deleted so my table looks rather strange.
Thank you, help greatly appreciated :)

Hello,
For my Year 12 Computing course, I need to develop a database which will take bookings for a village hall. The database consists of a Bookings Table, a Customer Data Table and a Hiring Cost Table. It is in the Bookings Table that I am having the most trouble.
I believe I have already solved my double booking dilemma by making the Date of Event and Type of Event fields in the Bookings Table into a composite key, thereby prohibiting the entering of data where Date of Event and Type of Event are the same, making them unique.
Here is my main problem at the moment, I need a validation rule on the Date of Event or perhaps the Date of Booking field which means a booking must be made at least a week, and no more than two months in advance of the date of event. The thing is this validation rule is only needed for occasional bookings. Present, again on the bookings table is a Booking Type field which has a lookup consisting of the following “Regular” and “Occasional”, regular meaning bookings that are made at the start of the year, for the whole year.
Ideally, I would like to have it so that when the booking type field is set to regular, the validation rule for the date isn’t needed, and when the booking type field is set to occasional, the validation rule for the date is needed/present.
Could anyone help me with this? As any help would be much appreciated.
Many thanks
Daniel

How can I set validation for a text field where I restrict the number of characters? For example, if I only want the user to be able to input 12 characters or less, and more than one. >=1 And <=12 would that be correct?

Hi all, Very new to using ACCESS. I am trying to set a validation criteria to ensure that a postcode is imported correctly. An example of a UK post code is SP10 3PB - it may be entered as SP103PB. I need to set a validation criteria to allow either two. What is the format of the criteria to achieve this? Any clues please. Thanks Mike
Are there any useful sites that set out examples of validation criteria?
Hi
I have a field for date of birth, however I want to make sure that the person is older than 17.
This is what I have at the moment but it doesn't seem to work:

Hello,
I am currently making a system for a sports centre and I need some help, I have created several forms one of which is for the coach's details.
On the coaches table we have a combo box which has all the different qualifications in it, we have 5 of these boxes but we want to it so that when one has been entered it cannot be repeated in the other boxes, also we want it so that when level 4 Tennis has been entered - levels 3,2 and 1 cannot be entered.
Any help on this would be great,

Hi Guys,
I need to set validation rule on a field. I have done the the below:
Private Sub Form_BeforeUpdate(Cancel As Integer)
If IsNull(Me.SlideType) Then
MsgBox "You have not entered SlideType!", vbExclamation + vbRetryCancel, "Incomplete Form!"
Cancel = True
Me.SlideType.SetFocus
End If
It works fine, but I cant get it ignore it if I press cancel. Sometimes this data is not available so it has to stay empty. When I press retry it should take me to that field to make changes and with the cancel click it should allow me continue with the last command/action before the msgbox was brought up. Can anyone please help, thanks.
Hi, does anyone know how to set fields(como-box) on a form to pop up a validation message when form:confused is attempted for saving without any data selected on the field. I have 5 fields and I wanted my users to get a message for each when left empty...help please:confused:
View 1 Replies View RelatedHi,
i have a form that requires validation. i am using the following code:
Private Sub Form_BeforeUpdate(Cancel As Integer)
If IsNull(Me.number) Then
MsgBox "number is required", vbOKOnly
Cancel = True
Me.number.SetFocus
End If
i have repeated the above code for other fields.........
The problem i have is, if i click 'x' and before it allows me to exit, it brings up the validations, one by one (so annoying).
Is there any way THAT it can show all the validations at once??? in one message????
THANKS
