i have a table with 3 fields: ID, line_item, and pay_app.
line_item and pay_app are linked to other tables in a one-to-many.
For every pay_app, there can be up to 100 line_items. However, I only want each line item to appear once (at most) in each pay_app. I want to prevent the same line item from showing up multiple times in the same pay_app. Essentially, I want to prevent duplicate entries, but with a stipulation, if that makes sense.
Can anyone tell me why I have 92,000 posts when I have only just joind today?
I am fast but not that fast.....
I'm really afraid to ask this question. I was working on a database for our LawFirm about a year ago but it was a longterm project and low priority. For reasons beyond my control I got away from it and am just getting to back to it. Miles and many of you were very helpful to me in answering my questions. I can't remember the user name I chose and my dob is not listed so I can't find it that way. I have searched what I thought was the user name and every combination thereof. I'm wondering if I got deleted after so long for inactivity? I certainly don't to waste people's time by asking the same questions a second time. Anyone have any ideas how I can find my old posts?
View 2 Replies View RelatedI realize this probably isn't the right place for this, but...how do I find all of my posts, whether I started a new post or responded to someone else's post?
Thanks in advance to whoever replies :D
Is there a way to find all my old posts except looking at all 381 pages?

I just added security to my access application...
I have added a new user and gave all admin rights. Removed all permissions from Admin and Admins group. When I log on as this new user who is equivalent of Admin,
I am able to doubleclick the table(linked table) and modify/delete the data..but when I the form is executing, it says, "Records cannot be read, no read permission on <Table>"
Hope someone can answer my question.
Thanks very much.
Congratulations on your 2000th post since July 2005.
That is indeed impressive.

Hi there!
I`ve been using Access DB for a forum for about two years now, but from time to time I have to download the db and delete about a 1000 posts (+/-).
The reason for this is that the db want accept more posts unless I do so.
My question is how do I "extend" the db to accept more posts?
Thx in advance,
Sarre
I don't appear to be getting any email notifications of posts in threads to which I have subscribed.I have Instant in my profile/userCP, but have not been receiving emails for some time. I edited my preferences today again -- I set it to daily, saved, then reset to instant, and saved. Thought that the edit may tweak some anomaly???
View 3 Replies View RelatedWe are working on an Access (2007) database that is on a SharePoint Site (2007).
Currently the form is operational, but there is one last thing that would be nice to have.
The table is "Updated Headcount" which contains "EMP_ID" which are unique numbers stored as text.
In the event a new employee is entered in the system by another user on this site we would like to prevent any duplicate "EMPID"s from being entered and saved on the SharePoint, we would also like to alert the user and prevent the data from being saved.
All data is currently bound, so once the user makes a change it is made, no submit button is required.
We are running into some difficulties in doing a dlookup from the value entered and comparing to a column in the table.
TABLE - UPDATED HEADCOUNT
COLUMN in UPDATED HEADCOUNT - EMPID
FORM CELL user will input an EMPID - newEMPID
FORM CELL used for a dlookup to compare what user has entered to what is already in the table - duplicateEMPID
So below is what we are trying to do, we are sure there are a few commands missing....
=IIF(newEMPID=dlookup([UPDATED HEADCOUNT]![EMPID]), newEMPID, "Error, EMPID already exists")
I have a table with duplicate rows. How do I de-duplicate the table so that there are no duplicates and find out how many duplicates there were in the table.
Thanks:)
Please i am trying to create a form that will keep records of perspnnel but i want a situation whereby if someone enters a last name and first name that is already in the record, the database should send a message telling the user that such a name exists.

Any solution would be great.
Hi All,
I have a table that has a device column and a tag # column, I want to pull out a report that shows duplicate tag # for different devices, the tag # can only be assigned to one device, I received an excel sheet that has to be fixed, I have the sheet in an access table. Please help. For example: device 123 and device 345 have tag #abc. I can’t simply create a query to show duplicate for tag# because I can have duplicate # only if it’s the same device.

I currently have a table that had 30 fields, the unique fields are survey, date, and business name. I'd like to create a query that will display all of these records so that i can get rid of them. They were imported from another table that another user created. If survey, date, and business name are identical i'd like to get rid of them.
View 1 Replies View Relatedpls can someone point me in the right direction
have searched through the forums.
i have two fields Forename & surename i need to prevent duplicate records if the forename and surename match another record.
So this is a very basic question, listen up:
I have only one table in my database. The table contains several text fields ( about 8 ).
The table is filled with very very much data. The problem is that i have a multiple
instances of the same data ( i mean apsolutly same, all the fields are same ) so
i need to delete copies.
Help please. Those copies are making me mad :mad:
Hi,
I need to make a database which wont allow any double bookings.
I've got all my bookings in a query and when a new date is entered (via a new bookings form) I need to make sure that date entered doesn't already exist in the query. I have tried a DLookup but it didn't work, however that is more than likely to be a user error, heh.
I've jumped in at the deep end doing this database. I've only done a few step by step databases before hand and the Access Help has sometimes helped my problems but I just can't find the solution on my own for this, I need somebody elses help.
Thanks a lot

Hi I've just signed up to the forum.
I'm currently working on a booking system, where clients can make appointments.
However as I am fairly new to access, I would like to know how I can inforce some sort of validation where for example if a client makes an appointment on 17/02/08, then it checks to see if there are any current appointments of theirs on the day, if there is, then an error message would occur
Hi, doing my project at college, decided to do a EPOS simulator for my sisters business based around barcodes etc and tied to a database. i've just knocked up something after normalising my data to prototype it to see if it is viable. I'm having problems with duplicate field entries. My db consists of essentially 4 tables at this point:
User : user ID, User Details
Product: Product ID, Barcode, Description, Cost Price, Sell Price
Transaction: Transaction Number, Date, User ID, Transaction Total
Transaction/Product - a compound key which is to manage the many to many that exists between Product and Transaction tables.
I am wanting to allow multiple entries for the same item, i.e. multiple scans, not a single sacn followed by a quantity. I keep getting an error message though that syas I am duplicating fields. I have tried altering the Index property for the fields in the Product/Transaction table but htis has had little effect.
Any thoughts please as to how to do this? I have attached the db for examination.
many thanks, Lol :D
I have a many to many relationship, and one of my tables (the junction table) has only 2 fields (BookID & AuthorID). These fields together are set as primary key, in order to avoid duplicate records. Eventually, if i will try to put a duplicate record, i will get Access error's message "The changes you requested to the table were not successful because they would create duplicate values in the index, primarykey or relationship ..."
What is the best approach in order to check whether a duplicate record is going to be created, and if yes, i will get a customised error message rather than the above mentioned default error message ?
Thanks
I have a medical database (Access 2003) containing information about patients. There is 1 form that is used to enter the information and a check box to say whether the patient has cancer.
I run a simple query to select the cancer patients.
I want to be able to add a large amount of information about (only) the cancer patients through a separate form. I also want a neighbouring hospital to be able to add cancer patients.
The ideal solution (I think) is to create an extra table to contain the extra information for cancer patients, and some of the informationfrom the original table. Cancer patients need to be automatically added to the cancer table once the "cancer" box is checked.
So far I have not ben able to achieve this - a create table query does not update automatically. I have tried creating a new table with the cancer information and creating a relationship between the tables and basing the form on the cancer table and a select cancer query. This does not work either.
Please can anyone suggest a solution! Do I need another database?
Thanks
Hi
I have a table (which is populated by people filling in a form) which contains two fields:
Section
WeekCom (e.g. week commencing)
I want to make sure that the form will not allow someone to make a double entry. For example, if Sally goes in and says enters "Benefits" as the section and "WeekCom" as 15/10/06, and then Ben tries to do the same - the form will not allow Ben to enter it.
How do you do this please? The table does not have a primary key at the moment....is there any way of doing it without setting one of the fields as a primary key?
Thanks
Maria
hello,
In excel i used the following formula =IF(COUNTIF(U$2:U$900,U3)>1,"Duplicate","")on one field to find duplicate, but I cannot come up with similar formula on column fields in a table.
Any guidance?
Thank you in advance
