Create Record If None Exists
Mar 23, 2006
I have a table (tblSales) with these fields (RecDate, Code, Type, OrderCount).
I also have a linked table (lnkSales) with these fields.
Daily I append the data from the lnkSales to tblSales.
The tblSales table must have a record for each code daily.
These are the codes (01,02,05,07,09,10,15).
I need to automatically add a record for each code that wasn't appended.
For example,
lnkSales contains:
03/22/06 01 Mc 3
03/22/06 02 Mc 1
03/22/06 05 Mc 1
03/22/06 07 Mc 2
03/22/06 10 Mc 1
When appended to tblSales there is no record for code 09 or 15.
I need to add these records to tblSales
03/22/06 09 Mc 0
03/22/06 15 Mc 0
Can someone explain the best way to accomplish this?
Thanks.

Hello
I am trying to figure out how to make my database check to see if the primary key value is a duplicate of anything ive entered previously and if yes, for my database to bring up that record instead of adding a new record.
I know how to do bring up records using a separate combobox (find) but I cant seem to do it using the primary key field itself.
Many thanks in advance.

Hello all,
I have a form that looks at my "master table" where users put in general info about a sheet of material.
There are two combo boxes on this form, Batch# and Lot#. They will use the same Batch# and Lot# for many sheets. Every time a new batch and lot are entered, this will bring up a pop-up form where the user needs to take a measurement of that batch and lot for QA. This will go into a different table, where the batch and lot #'s are unique(many of the same batch#'s with different Lot#'s).
After the lot# is entered, I want to run a query in VB that looks for those unique identifiers, and if it doesn't find a record, my pop-up form will run.
This is probably something very easy....... It was a very long weekend and I'm tired of thinking.
Thanks
Scott

Hey all,
Tables
ProductsProductBrandSize
PurchaseDetailProductPriceQuantity
Forms
frmFoodSub
Combo BoxesiProductiBrand
TextboxsiSizeiQuantityiPrice
For a couple of days now I've been trying to devise a way to achieve what I want, but I just keep going in circles and hitting errors (thanks to forum members, I've been able to solve most of them.) So, here's what I want to be able to do:
Input a product using the iproduct combo box (which gets its list of values from the Products table); its brand, using the ibrand combo box; and its size using the isize textbox, all in the frmFoodSub form. I then want it to check to see if an exact record already exists (ie. the same product, same brand, same size.)
If it doesn't exist, I want to create it. If it does, I want to do nothing. Then I want the product - either the one I just created, or from a record that already exists matching the iProduct input - to be input into the product field of the PurchaseDetails table. I then want to use iQuantity and iPrice textboxs, already linked to the PurchaseDetails table, to input the newly added product's quantity and price.
I hope my explanation was clear enough. I'd appreciate any help with this you may be able to offer.

I have created a form which enbles users to enter data into the fields which will add a new record to my table. What I am trying to do now is to create some kind of validation rule that will check whether the record already exists.
I need it to work this way; there are four input fields- 3 text and 1 is a date filed. When the user enters a new record they are not allowed to create a record that conatins the same combination of values. So if one record has for example filed 1 = 1 field 2 = abc field 3 = def; then no other record can have the same combination of values.
If the user enters an already existing combination there would be an error message saying which field is incorrect. If the combination doesn't exist it would add the record and display a message that the record was successfully added.
How can I do this?

I have a form, which has a combo box which a user can select an employee - the combo has three columns (Employee_Number, Surname, Initials) although the Employee_Number column is set at a 0 width, so not visible.
The form is bound to a query which only shows records that are 'Active'
When a user selects and employee in the combo box, I want the AfterUpdate event to check and see if there is already an active record - if there is, throw up an error message and then reveal a couple of buttons giving choices what to do next; if there isn't an active record, reveal three textboxes and then populate those textboxes with the values from the three columns from the combo.
The bit that is sticking me is the search - - I have tried DCount, but can't seem to get it to work
Here is the section of code that I am battling with:
Code:
Dim EmpNo As String
EmpNo = cboEmp_Check.column(0)
If DCount("Employee_Number", "Incomplete_Training", "Employee_Number=" & EmpNo) > 0 Then
MsgBox "Existing", vbOKOnly

I am trying to check if a record exists in a table.
Dim cert As String
Dim existingRec As Variant
existingRec = DLookup("[Certificate]", "[Fire]", "'cert' = 'cert'")
If existingRec = Null Then
Else
MsgBox "The Certificate " & existingRec & " is in the database"
End If
Note - Certificate is a column in the table "Fire"
Problem is that existingRec only finds the first value in the Certificate column, How do I get to check the entire Certificate column?

table A has 10 records where 1 field is set as REQUIRED/UNIQUE. the table B does not have any record but have a same field like table A. what I want is that if user insert the record in table B it should first check whether record is already present in table A or not, if already exists it should not accept insertion. and if not already there in table A it should insert record in table B.

What is the best way to warn a user if a record already exists?I've looked at some examples that use an SQL SELECT statement with a recordset to compare existing records against the one the user is entering but i'm not sure which event this should be triggered by - eg; would it be the control's 'After Update' ,on 'Dirty' or 'Change' event? Would the record have been saved when the 'After Update' is fired- if not then it would not be found in the recordset and the SQL would not work....
how to create a textbox function that automatically searches and completes the textboxt based on exisitng records (like the cell autocomplete feature in Excel)? This could then populate the form with the existing record fields (if found ) and the user could update the record if necessary?

I have a table with a 3-part primary key. Have a form with 3 unbound controls corresponding to the 3-part table key.
After the 3 form fields have been entered, I want to search the table to see if a record with the same 3 fields on the table exists. If it does I want to go to another form to enter data for a related table carrying forward the 3 key fields.
If it doesn't I want to go to a different form to keep the 3 fields already entered from form 1 and add additional fields to complete the record.

I have a database that involves a lot of data about ppl and I'd like to prevent duplicate entries.
I have a form that gathers data. I'd like to have a button after name, surname and birthday are written.
A click on the button would display a msgbox that says that person already exist, maybe even with the added - edit the old entry/add new record anyway/abort options.

Hi,
In the current db there are some tables and queries, forms designed around them
With one table Test
http://members.optusnet.com.au/~lukechang/access/table_d.JPG
That has 3 records in them
http://members.optusnet.com.au/~lukechang/access/table.JPG
Just won't show in form anymore, at this stage
http://members.optusnet.com.au/~lukechang/access/form.JPG
The Form was working previously. This is the second time this problem has came up, I thought it would go away if I made a new form and pasted all the controls and codes. It indeed went away for a while until this problem hit me again...
This db is in Access 2000 format and designed using Access 2003
I would appreciate if anyone is willing to point me to the right directions, many many thanks in advance

I have 2 tables:
Query_Rates (Actually this is the result of a query):
Unit
R_Date
Sold_Rate
A
24-AUG-15
145
[code]...
So what I want is a list of all the records from the Query_Rates table where the absolute differences between the sold rates between Query_Rates & [Sent till date] (matching the unit # and the dates) is greater than 1 and the record shouldn't be displayed if it is already present in the [Sent till date] table. But if you notice the first record which has unit A is already mentioned in the "Sent till date" table and shouldn't be repeated again in the query result.
The desired out put should be:
Unit
R_Date
Sold_Rate
X
25-AUG-15
200

I'm tracking the holiday entitlement of a team of people. I use a query to work out how much unbooked holiday they have to take.
My problem is where I'm scheduling next year my query returns the names of those who have booked a holiday and their remaining entitelement. That's as it should be. However if someone hasn't yet booked any holidays then it simply doesn't display their record. I would like it to treat that record as zero and show the remaining entitlement as a full years entitlement.
Here's the SQL
SELECT Employees.Trainer_Name, Sum([2015 Holiday].[2015 Days]) AS [SumOf2015 Days], Employees.Holiday_Days, [Employees]![Holiday_Days]-[SumOf2015 Days] AS 2015
FROM [2015 Holiday] INNER JOIN Employees ON [2015 Holiday].Trainer_Name = Employees.Trainer_Name
GROUP BY Employees.Trainer_Name, Employees.Holiday_Days;
The problem here is that the Sum of 2015 holiday is Null
Do I somehow need to create 0 hours records?

I am trying to achieve the following - I want to query a table to see if a record exists with a particular field blank. If so, I would like to prompt the user for data.
In real world terms, when assigning an item to a user I would like to first make sure that the item is not already assigned to somebody else. I have 4 fields, UserName, Item, IssueFrom, IssueTo. So when an item is assigned to a user, the first 3 fields are populated and the IssueTo remains blank, until that item is assigned to somebody else.
At the minute I have nothing in place to prevent a user from assigning the same item to multiple users and having multiple records for the same item in the table.

I have a table in Access that I have a form saving new records to. Before this save occurs, I would like Access to check if the account number already exists and if the account does exist if it is outstanding. If both of those conditions are met I would like a message box to display and cancel the save as it is a duplicate. I can't seem to get it to work though.
I was thinking to use a filtered recordset based on one of the conditions and then perform a find on that recordset to see if it is null.
Code:
dim acct as long
dim rstfiltered as DAO.Recordset
Set rstfiltered = CurrentDb.OpenRecordset("SELECT * FROM tblclstrack WHERE [Request Status] <> 'Completed'")
acct = Me.cd_number.Value
[code]...

If the record doesn't exist I would like to be able to add a new record with the data input. What is the best way to accomplish this?

I think I know the answer to this, but thought I'd see if anyone had any ideas... I was asked if there was any way to know when a record was created in the database. When the table for these records was created, a field for "Enter Date" (i.e. the date the record was enterd into / created in the database) was not a part of the structure. I know that for going forward, we can create this field in the table and have it populate with Date() behind the scenes so we can track the actual enter date. But, for the records that are already there, is there anything that Access keeps somewhere as to when the record was created in the table?
Thanks in advance~

hi everyone,
i think this must be easy but im new and despite reading lots just cant figure it out.
i have 2 tables
job details:
autonumber
customer
location
time
picking list:
autonumber,
equipment1
equipment2
equipment3
both the autonumber are primary and linked in a relationship.
when i create a new record in the job details table i need it to automatically create the coresponding blank line in the picking list table with the same number. If I enter something in the picking list table then it creates the matching number and everything is ok but if i dont then it throws my numbers out.
any idea how to get it to do what i need,
thanks

I have a program that you can search all or a specific record. Once you find the record, you can double click on it and another form will open up with only that record's information.
What I need is to have a button that will copy this record's name, address, phone number, contact info, and etc --> and create a new record with a new Record Number using the current record. This will allow the user to avoid entering in the same information again. For confirmation purposes, I would like to have a SAVE button to verify and save to the DB.
Does anyone have any inputs on how I can do this? If you would like to see the program, please let me know.
Thanks in advance for all your help and suggestions!

How do I create a new record (in the table to which the form is bound) automatically if, when the form opens, there is no record in the table that meets the criteria in the form filter?
Thanks!
