Modules & VBA :: Check If Record Already Exists In Recordset Based On 2 Conditions
May 27, 2014
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
I have a module that I am using to verify that file paths in my table point to valid jpg files. The table has grown quite a bit since I first created the module and it has gotten to the point where it's taking too long for the module to execute. I'm in the process of trying to change the record set for the module from the table to a stored query procedure but it's turning out to be a little tricky for me. When I execute the following module, I'm not getting any error code, it just doesn't seem to do anything at all. The bits in red are the parts I've changed. Before that the module executed as I expected it would.
Code:
Sub TestIt2() Dim strFileName As String Dim db As DAO.Database Dim rs As DAO.Recordset Set db = CurrentDb() Set rs = db.OpenRecordset("QryUpdateRevisionHistory")
I am storing values of pictures and the location of them in a table, this works fine!... using OpenRecordset. The problem is that when the function is called to store the information, it just keeps adding the same values of each file in the folder over and over again in a word "Duplicating" the information.
I have tried various methods using the OpenRecordset, but cannot seem to find the correct manor of applying the code.
Below is the function I have for storing the data...
Code: Public Sub GetFilesNamesFromFolder(strFolderPath As String) On Error GoTo ErrorHandler Dim objFSO As Scripting.FileSystemObject Dim objFolder As Scripting.folder Dim objFile As Scripting.File
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
In order to arrive at the required solution I have to perform a calculation, using data from each successive table record (in chronological order). The result of each calculation must then be used to arrive at the result for the next calculation.
In other words I have to update a variable based on data from each record, sorted in chronological order, and use the final result to populate a field on a form.
Is it time to break out my copy of "VBA For Dummies" and start learning how to use Recordsets?
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.
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 an application that I have automatically checking to see if tables are valid and connected, etc. If the app finds that the tables aren't connected or aren't working, it automatically tries to re-connect those tables in the background without the user's knowledge. The time I'm having trouble is if the SQL Server doesn't exists (the back-end tables are on a SQL Server). I would like to check to see if the SQL Server exists before I try to re-connect tables so that no SQL Errors pop up but I'm not sure how to figure that out with VBA.
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
I can already send emails out as PDF files when an email address exists, however, I'm trying to validate whether or not an email address does actually exist. My problem is, there are four possible locations where an email address could be: MainEmail or Contact1Email or Contact2Email or Email (the last one - Email - is in a separate table).
Four text boxes exist on the form that is being actioned (the form is based on a query to extract the relevant information) and are available to test for an email address being present. What I'm struggling with is ensuring that the 'To' box in Outlook always gets populated or Outlook chucks a hissy fit. I have been trying various IF Then Else and Do Loop plus a myriad of other ways but none are reliable, especially if no email address is present which can be the case.
I have code working for some workers here ,who used to save excel files in a folder and my databse upload those files into database and then do the rest.I am looking for a code in vba which,on upload button matches the file in table and if the file already exists ,it should not upload again in the table and if it does not exists it should upload . I have attached my code below :
Private Sub Command0_Click() Dim strcPath As String strcPath = "O:QA FilesQC ReportingPending Review" Dim strcNewPath As String
Actually what I am looking to do is have an Access application check some Web site for the presence of a number. This number could be the Serial number of the application and if this number exists to maybe show a message in the aplication or even terminate the application.
A quick and dirty way is for User Serial number 254, to put on a specific page of a Web site say arbitrary file 254.jpg (invisible on the Web site). The application would check for the existence of this file and if it is there, it could take some action. Everything would have to be done in stealth mode.
The following code can tell me if a specific URL exists, in this case [URL]
Code:
Private Sub cmdArbitray_Click() Dim blnDum As Boolean blnDum = blnCheckURL("http://www.VisualDentist.com") ' If blnDum = True then it exists End Sub Public Function blnCheckURL(ByVal strURL As String) As Boolean Const FLAG_ICC_FORCE_CONNECTION As Long = &H1 blnCheckURL = (InternetCheckConnection(strURL, FLAG_ICC_FORCE_CONNECTION, 0&) <> 0&) End Function
having a corruption issue with my database, it happens when a user updates a record and a second user has that record open elsewhere. then when the second user closes they save their changes over the top, corrupting the whole record.
so i need to know with a recordset if there is a way to check if a second user is currently looking at the same record?
--> check to see if two fields matches e.g (qty=qty_completed)
--> if all records in recordset meets the above condition then run update statement
I want to put this code inside Form_Close. The code that I'm using checks the two fields for the condition and runs the update statement if condition is met. Problem is this a continuous form and I want all records need to meet the condition before it execute update statement.
Basically, if Calendar date > Date(), if Calendar Date not Saturday or Sunday, weekday(Calendar date<>1 and <>7), AND Calendar Date not in (Holidays table).Then repeat the last not = 0 value of MyValue. I thought of changing the default value but the value is already 0, while default is null + I need to set the default value under certain conditions.
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 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 filed and I want to find out its length then in the next column i have to add the data like if filed 1's length is 1 then it should be 000+field1.value, if it is 2 then 00+field1.value, if it is 3 then 0+field1.value and so on...any help is appreciated , thanks
Simple example is I have say 3 recordsets open (they are opened once as they are refered to many times) - they are open early in the form (in this example 3 price lists that are applicable for a customer) (if the syntax of the select is slightly wrong I'm just showing to 'prove' the concept).
Dim db As Database Dim rs1 As Recordset Dim rs2 As Recordset Dim rs3 As Recordset Set db = CurrentDb() Set rs1 = db.OpenRecordset("SELECT * FROM Prices WHERE (((Prices.ID)=1));") Set rs2 = db.OpenRecordset("SELECT * FROM Prices WHERE (((Prices.ID)=2));") Set rs3 = db.OpenRecordset("SELECT * FROM Prices WHERE (((Prices.ID)=3));")
What I want to do is have a central function that I can pass a list I wish to process/do something with aka. The 3 recordsets are the same except for the where criteria.
private sub GETPRICEFROMLIST(pricelist as long)
dim rs as recordset
set rs = Recordset("rs" & pricelist) .....
I put the above to show what I'm trying to do but of course that doesn't work There won't be any updates to these recordsets only reading of data.
I have a form in my front end database that is supposed to allow a user to search for a record based on account number and then make changes to the that record and for it to save in the back end database. I have the search function working where it populates different input boxes on the form with what is stored in the back end database but I cannot get the update function to work. I have tried to assign each input box with a variable and then run an Update SQL function to update each of the fields but the updates are not storing. Any example of a successful update statement that uses VBA variables in it or a way to update a specific record via a recordset type function?
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.
