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.
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.
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.
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
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 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
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.
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
The problem I have is, that I need to insert an apointment into de database but first I need to verify if there is a record or an apointment in that room that day the same hour, if that is so send a msgbox saying an apointment already exist in that room this day at this hour.
i tried using dlookup but it only works in one record using just one criteria
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.
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
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
Tables join using fQSRegno. Scenario is Tbl Individual contains all the members info.Tbl Point contains point given to members who attend courses. Problem is when I created a query...
I have 2 identic tables: T1 and T2 which contain only one field NR.
T1 contains the data: 1 2 3 4 5 6 7 8 9 10 11 12
T2 contains the data: 5 6 7 8 A B C D
I want to select all the records found in T1, but not found in T2. So, I wrote the following SQL query:
SELECT T1.NR FROM T1 WHERE NOT EXISTS (select T2.NR from T2);
Unfortunately, this query doesn`t return any record. And the strangest thing is that the query:
SELECT T1.NR FROM T1 WHERE NOT EXISTS (select T2.NR from T2);
have the same effect like:
SELECT * FROM T1,
I mean it returns all the records of T1. I mention that the query was written in Access. What I have to do? Can anybody help me? What solutions do I have? I need a query, not a VBA code!
I need to make a query that only selects data that is in another query/table.
I have tried to do this using a query with IN criteria as follows.
SELECT fldOne,fldTwo,fldThree, FROM tblOne WHERE (((tblOne.fldOne) In (Select fldOne from tblTwo)) AND ((tblOne.fldTwo) In (Select fldTwo from tblTwo));
But that isn't working. Any ideas as to why?
I think that the answer might be using the EXISTS reserved word, but I don't know how.
How can I do an existence test on a table in my Access MDB in a script. The job is to determine if a temp table exists, and if so, then to drop the table.
What syntax would I use to accomplish this in form event code?
Hi, I have the following problem which I hope someone can help me with:
I have a form which is used to enter data into a table. One of the fields is 'Code'. I want the form to check when data is enetered into this field is it already exists, ie if the code is already present in the 'code' field in the table, and if it is it should give a warning message, if not then continue as normal.
Any help would be greatly appreciated, thanks in advance!
I have a form used to enter new contacts. I would like to insert a query or macro that would automatically to see if the name (first and last) already exists in the table to which this form is attached. If the name exists, I want to open the existing record and add information to it. If not, I want to enter the information as a new record.
