I have a table of animals each with a unique ear mark. I also have a table of vaccination records. When adding new records to the vaccination table via a form i would like a validation check on weather the animal actually appears in the animal table or not with an appropriate error message. Please help.
Many thanks.
hi can anyone tell me all the different types of data checks that can be used in database tables such as field length check and range check
thank you
i have a combo box which basically gives you the option of yes and no.... then if the yes is selected, you choose a time from another combo box
i want to be able to write an IIf statement which basically hides the second combo box unless the first one has the value 'yes'
Can anyone help me please???
I want to uncheck a check box field for all records in a table. I want to do this with a push of a button which will implement a function or sub or query that clears only that field. I?d like to know:
a) How will this hit performance? There will be approximately 150 records (max) that will be effected. Is this something that will slow the system to a crawl? If it takes a minute or so for these records to be altered, I can live with that.
b) How can this be implemented? Say a user hits the button to clear them, how does it get implemented? For instance, a select statement that grabs all the records that have -1 (a ?check?) in that field and then do an update statement for each one that changes it to a 0 (unchecked). Any suggestions?
Thanks,
scratch

how can i bring data from column in table to form and choice from data by checks box ?

2- It is possible to choice more 1 check box .
example:

I am raring to your answer
I have a report. In this report I have a start date and an end date. I also have a date that is going to be checked. The report checks to see if the date the user entered on a different form is between the start and end date of an individual. if it is, a txt box at the end of the line will turn red. If it isn't the box will stay default of green.
What I would like to do is not even show the lines that have a green box. I want to just show the lines that have boxes as red.
I looked into If statements but I'm not quite sure what event I should put them on, nor am I certain I have the syntax right.
I had it:
If (lblAvailability.BackColor = "#CCB13D" Then
txt1.Visible = False
and so on... making all the txt fields invisible. I would rather have them not even show up because I'm pretty sure invisible things still take up room.
End If
I need a query run that brings up a list of customers that need maintence after 6 months after their last maintence service. As soon as you open the DB, the event/query runs and if there are any customers past due to display them. And if there are none, to not even show the query at all.
I have very little experience with timers and if/then statements and don't know how to set this up.
Any help would be greatly appreciated. Thanks in advance.
I have a table with yes / no field named cleared for checks.
I want to make a search form with combo box to query for cleared (yes) and not cleared (no) checks.
I tried combo box with values set in it, yes and no.
But it didn't work.
I have a query which shows data about certain checks that are carried out employees. One of the fields is Expiry Date of the check. What I want is for the query to show only records that have a expiry date which has expired or is going to expire within the next three months of today's date. But I cannot work out how to do it!
View 2 Replies View RelatedI am looking to generate a total number of a given column based on two criteria.I would like a label (or textbox if necessary) to display a given total of "Active" devices based on a given month.The table name is "Blackberry" and the specific columns I would like to check would be "Activated?" and "Registration Date". I'm not sure if I should be using a dsum or dcount and the error i keep getting is a type mismatch.an active device would have the text value of "Yes.

Just curious how access stores records. Say, data type of Text, field name "FullName" when entering data via forms normally we use formatting or enforce data entry with validation rule to check say if user typed in propercase or cases that we desire to see. So far so good. When text format masks is applied for instance > or < , does the actual data or the formatted data is passed to the table layer. Alternatively, table layer format vs form layer format which one of the methods dictate what exactly is stored under the table.
View 13 Replies View RelatedNo records are being imported. I am getting a validation rule violation but I don't have any rules. The forename and surname are straightforward text boxes and the ID is an autonumber.
Code:
INSERT INTO table_candidate ( Cand_ID, Cand_forename, Cand_surname )
SELECT candidates.Cand_ID, candidates.Cand_forename, candidates.Cand_surname
FROM candidates;
1. Is your append query trying to assign values to the primary key field? Could that be the source of the duplicate?
Yes but there are no duplicates
2. Do you have any other fields that are "Indexed: No Duplicates"? Any compound indexes?
No
3. Is the query assigning values to a field that is a foreign key to another table? Is it possible that these values do not match the values in that other table?
No. All child tables are empty.
4. Is there a validation rule on the table itself?
What this means.
5. Does the query attempt to assign a string with no characters in it (as opposed to a Null value) to a text field that has its Allow Zero Length property set to No?
Both fields are text and all records contain information
Required = No
Zero length = Yes
6. Is there a Default Value in one of the fields that is NOT being assigned by the query? For example, a foreign key with zero as the Default Value?
No
7. Is there data that is outside the range a field can accept, e.g. an integer larger than 32767, or a Null to a Yes/No field?
The length of the text in each record is not greater than the set limit
8. Is one of the query fields arriving in a format that Access is not understanding, e.g. for a date, or for a currency?
No
how can i validate a field so that the data entered must be between the values of 1 and 10?
thanks in advance
I have a table called Inspection, there are two fields:
- Damage To Property // data type is Yes/No
- Damage Comments // data type is text
How would i go about setting the validation - if Damage To Property is data type "No", disable the "Damage Comments" field. (ie grey it out).
any help would be greatly appreciated..
Hello!
Can someone tell me how to do a validation. The one I am trying to do is check Track No is not duplicated.
I have added my database if you may need it.
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?

I'm really new to Access and need help with a validation rule
Right, i have a 'Date of Birth' field and what would the validation rule be if i only want people over the age of 12 to be able to go any further?
I've tried various other rules found online but some just don't work...
Any help would be great!

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:
