I am trying to check if a record exists, but I keep getting a error!!!
Private Sub Command10_Click()
If DCount("*", "tbl", "[ID] = "") <> 0 Then
MsgBox "This record already exists.
Else
stDocName1 = "McrAddNewRecord"
DoCmd.RunMacro stDocName1
End If
End Sub
I'm running the following line:
dbs.Execute ("DROP TABLE [tbl_No Certs]")
the problem is that sometimes the table doesn't exist... Instead of trapping the error code, is there a way I can check to see if the table exists? If it doesn't I'll simply skip this step of my code and move on.
Thanks!
I have tried the attached code from a previous post http://www.access-programmers.co.uk/forums/showthread.php?t=98727&highlight=table+exists but some of the code doesn't work on Microsoft Access Project.
Does anyone have any ideas how I would amend this code so that it works?

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'm trying to use DCOUNT to check to see if a date exists and if it does then i can cancel the input. The code im using is as follows however its returning datatype mismatch.
Code:
If DCount("[pick_date]", "tblPicker_Stats", "[pick_date] = '" & txtPickDate & "'") > 0 Then
MsgBox "Statistics for this date already exist", vbOKOnly, "Error"
End
End If
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 expression to determine if a duplicate records has been entered.
DateAte is a date
MealType is a list box (text)
All I want to do is prevent two lunches, etc. from being entered on the same date. Code that results in the message box every time, regardless if a duplicate record or not.
Private Sub MealType_AfterUpdate()
Dim strDA As String
Dim DA As Date
DA = Me.DateAte.Value
strDA = "[DateAte]=" & "#" & DA & "#"
If DCount("[MealType]", "tblmeals", strDA) > 1 Then
[code]....
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 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 currently use
Code:
strSQL = "INSERT INTO tblDepartments (Department) VALUES(txtnewdept)"
To insert new departments into a table, however id like it to check to see if a department name exists in tbldepartments.department to prevent duplicates being added?
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.
I have a transaction form and there is at least two fields I need to make sure have been entered before the record is saved.
I have no problem with text or numeric fields but I can't seem to be able to check the contents of a drop down field.
What is the best method to use to make sure a drop down has been selected by the user and contains a value.
I have temporarily used a default value in the drop down but that's not really what I want.
What would be the Access 2007 VBA code for checking for duplicate records?

I have a code which cut the data from tables and insert to others. The problem is I don't know when I can do this process (when I will cut data and the same time some users lock editing records then I will get an an error).

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
