How Do I Check For Record Before Update?
Apr 13, 2005
I need to know how to check if there is a record set matching a name and insert record if there is not one, otherwise just update if a record does match. See code:
Code:<%Name = request.form("name")picture = request.form("picture") opencnset rs = Server.CreateObject("ADODB.RecordSet")'if no record matches the nameSQL1= "INSERT INTO background (Name, Picture) VALUES ('" & name & "', '" & picture & "')"'elseSQL1= "UPDATE background SET Picture = '" & picture & "' WHERE Name= '" & name & "'"cn.Execute SQL1closeCN%>
Thanks in advance for any help you all can provide!!!! -Chris Gordon

I have a transaction table the last record is [EquipIn]. during the equipment checkOut process all the other headings in the table are filled in. The idea is to fill in the [EquipIn] record a couple of days later when the equip is returned. How the heck can I make a equipment check in form that will update that one record? I can't do this manually as we have 1000+ pieces of equipment.

I have a table called tblCompanies. When a company acquires another company, I need a method by which the acquired company's CompanyID (PK) can be updated to the new company's CompanyID (PK). I also need to be able to update all related CompanyIDs (FKs) to the new value in related tables.
In cases in which the new company does not have an existing record, there is no problem: the company name simply gets changed to the new company and the existing CompanyID is maintained. I then use an audit table and Track Changes function to keep track of the company name data and a union query to keep the old names in the selection lists.
The problem is when both companies already have existing records in the table.
So, let's say I have records for Company A and Company B. Company A merges with Company B and Company B is now the main record. What is the best, simplest and easiest way to update the CompanyID (PK) from A to B and change the CompanyID (FK) to the new value in all related tables?
I am envisioning a pop-up form that directs the user to select the new company and then an update query happens behind the scenes... but exactly how does the criteria for the update query get selected and how do all the related tables get updated? My vba skills are pretty basic, will I need extensive coding to do something like this?

I have a database that consists of applied, accepted, and enrolled students in which I have three separate tables for each. In each table I have SSN, Year, and HighSchoolCode. I also have check boxes in each for accepted and enrolled. My question is, how can I get the check boxes in my applied table checked if the SSN and Year exist in the accepted or enrolled table respectively? Please help

I have a form that lists records that contain things to do with a check box. If click on the check box, this signifies that the item is complete.
Is it possible to put some kind of event in that when I click the check box that the record automatically goes away instead having to exit and come back in?
It would be a simultaneously update in the form I would imagine. I use the form all day and keep it open. Would be helpful that I can have the form updated automatically.
Thanks,

I have an application that enters candidates in, who apply for a job.
I found that I can enter a candidate in, and if I dont enter at least an address type or phone type ( giving that candidate an address record, albiet a blank one (just a type of address) and a phone record) then the candidate wont have a sub record for addres or phone at all.
This is hurting my reports. They are set to pull the primary address and phone only, as we dont need to have 2-3 contact information for a candidate on a report This is how I found out that I had blank address and phone for some test records. I need to be able to check when a person does a number of things, that at least the combos for phone type and address type have been chosen as something. This will ensure that they have a primary address and phone, as I have code that takes care of all that. I tried putting the following code in the form's before update, but since it is calling to a subform, the minute I tab TO the address combo, I get the message. The form is updating before I get the chance to skip the field.
Here is the lay out. A user can enter in candidate, their address, phone, application and activities. Address, phone, applications and activities are all sub reports on a tab control. The user should be able to move freely within any record, and only be bothered when they try to leave, if important information is still empty. I dont want to control how they enter ('you must enter this first!' lol) just that they do enter it in the end.
What I want to do is check when the user is leaving a record.(closing form, going to another record, clicking the search button that opens another form etc) if either combo is empty (no primary contact info) then it gives the message and goes back to the combo that is empty.
Here is the code I have. If anyone can help me find the right place to put it, I would really appreciate it. Thank you,
If IsNull(Me.[subAddressEntry].Form![cmbAddressTypeID]) Then
msgbox "You must enter an Address"
Me.[subAddressEntry].Form![cmbAddressTypeID].SetFocus
Cancel = True
ElseIf IsNull(Me.[subPhoneEntry].Form![cmbPhoneTypeID]) Then
msgbox "You must enter a Phone"
Me.[subPhoneEntry].Form![cmbPhoneTypeID].SetFocus
Cancel = True
Else: Cancel = False
End If
If I can't figure this out, I am thinking of making a new address type and phone type. Call it "none chosen" and then make that a default selection. Then one would always be chosen...I think. I would like to avoid that though.
Thanks again.

i'm making a database to catalogue a whole bunchs of projects of mine. i have a few
questions but i'll ask one for now. i have made a form with a check box and i want it

Help! I'm designing a database for my A level project at college and I just can't get this one section to work. I've spent alot of time linking things up so that you can't double book one of 4 rooms. It's a booking system for a recording studio. The thing is I have 3 basic packages of equipment and you can only choose one for each booking. The price is diplayed at the bottom of each package. I want to be able to check a box and then I want this price to be added to total price. I cannot link update queries to a check box I've tried every songle way I know. I'm not too familiar with access either :S. One more thing, I want to be able to tick a box which says Discount and then I want this to update the total price field again so it is multiplied by 0.9. I have manage to figure this out in an update query and it is also based on the fact that a band has made a deposit that is bigger than £0.00. I just cannot link it to the form.
If anyone can help it'd be much appreciated, I'm panicking too much over this project.

I have a form which is based on a query which selects information from three different tables. All fields apart from one are locked, all are enabled. The table the field I wish to update is native to the current DB i.e. is not a linked table.
when I activate the form and try to click on the Check box, which is not locked, I get a beep but it does not change state.
I am using Access 2007 on win7 Pro.

I need to have a query-based form open and allow users to check off (or otherwise indicate) which records they want to update.
I tried having a check box on a continuous form, but when you check one, you check them all. I did a search on this, and saw that if you make the check-box bound, then that will work. But I don't know what to bind it to. I don't want to add another field to an already large and complex table, and I don't know where to put it if not in main table.

I'm working on a code that checks all blank/null text fields and combo boxes in a form and notifies the user if a field is not filled. The code below works if all fields are required, but I can't use it on forms that have fields that are not really mandatory. I've read somewhere on the net to use tags on the controls i want to skip checking, but that's where i get lost.
Code:
Dim stdResponse As Variant
Dim ctl As Control
' Enumerate Controls collection.
For Each ctl In Me.Controls
' Check to see if control is text box
[Code] .....

I'm sure the coding is very simple, the question is .... can I build an expression using an IIF statement that checks whether the current field is the same as the same field in the next record? If it is put a 1, if not put a 0. Easy in Excel, not sure about Access??

Hi Everyone
i would like to check a record exits before a new entry is saved. However i would like to check on three criterias and i am not sure on how to write the if statement.
IF Dcount "CompanyName" & "FirstName" & "Last Name" from "tblcustomer" is the same as "frmCompanyName" & "frmFirstName" & "frmLastName" > 0
Then
Msgbox "This Customer Already Exists"
Cancel = True
frmcompanyname.setfocus
End IF
Could someone please translate it into the correct code?
Many Thanks

I am running a check for checking whether a value already exists in the database table. But the problem is that the control passes right through this check.
It does not give an error too...
If txt_id.Value = DLookup("id", "indicateur", "id=" & txt_id.Value) Then
info = MsgBox("Cette 'Id' déjà existe !", vbInformation)
whats wrong with this 'IF' loop??

I would like help with a macro that looks to see if a record in my database table exists, then if it doesn't it adds a record with my data, but if the records does exist, it stops the routine and sends a message box to prompt if you want to continue with adding a new record.
The problem that I'm having is that my macro errors out when it doesn't find a record. I just want my macro to just see if a record exists or not. Then I can write my Iff statements based on whether it finds our or not. How do I just have my macro check for an record, then if it doesn't exist tell that it doesn't exist and not stop my macro. Is there some kind of IfExist() function or something?
Thanks for any help anyone can give me.

i want to be able to create an On Click Event when pushing a command button that will run an Update query to update a record and after it has been updated that specific record will pop up on a Form and be displayed. i know a different way is to run the Update query and then have it displayed in a Select query but i want it to be displayed on a Form instead. is it possible?

I need a way to dynamically store a particular value in "field_2" of the CURRENT record depending on whether or not the value of "field_1" of the CURRENT record is identical to the value of "field_1" of the PREVIOUS record within the same table. The table is sorted on "field_1".
So, if the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is also "ABC", then store a value of "PPP" in "field_2" of the current record. IF on the other hand, the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is "XYZ", then store a value of "WWW" in "field_2" of the current record.
I have a report that will use these results to count only the number of records that have a "WWW" in "field_2".
Is this doable, maybe in a query somehow?
I should add that whatever the solution, it needs to be compatible with Access 2000.

How do you make the spell checker not cycle through all your records when you run it? As it is right now, when a user tries to spell check their entry into the summary block of my form it automatically starts with the first record in the database and goes from there.
This is in Access2003 BTW.

Hi.
I have 2 forms, with a "PNID" field as the link between the 2.
In the 2nd form, the PNID field allows no duplicates. I have a button on the first form to open the 2nd form to add a record.
I need some code to put on the button on the 1st form to check whether a PNID record exists on the 2nd form before opening it.......does this make sense?
What is happening is that I click on the button, try and add a record, then it tells me one exists and I cannot add a duplicate...
I have looked at the threads, and have tried using DCount? Is this correct?
Thanks
Frank.

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 a newbie to Access. I have a check box on my form that defaults to checked, meaning the record is active, what I want to do is when the box is unchecked, not have the record appear as an active record and just be on the table. I have the check box on the table and when I uncheck it on the form it unchecks on the table but don't know how to stop it from appearing in the active records. Thanks for your help, April

hey guys
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?
thanks
