Solved: No Data In Query If Subform Empty

For a typical Invoice table, the line items of the invoice are stored in an InvoiceDetail table, joined to the Invoice table by an InvoiceID.
Put the validation code in the BeforeUpdate event of the subform record to prevent the bad records from being saved. ladydee94, Feb 27, 2017, in forum: Business Applications Replies: 1 Views: 89 Keebellah Mar 1, 2017 at 10:52 AM Access - Building database to track workers duties help pls RJTX45, Feb Do these two constructs do the same job?

Most often this happens when a user begins adding line items to the subform without first creating the invoice itself in the main form. May 7 '13 #7 reply Expert 2.5K+ P: 3,072 nico5038 Hmm, I guess there are multiple loan types that can be selected for an employee and in a normalized datastructure you When the employee type is changed you can delete these records or set all ValidYN fields to False. https://www.experts-exchange.com/questions/28579219/MS-Access-form-is-blank-if-no-records.html Unless you set the Required property of the InvoiceID field to Yes in the InvoiceDetail table, Access permits Nulls.
The logic behind your premise is flawed. If some error then display message Else force save End If Select all Open in new window Looks nice but it doesn't Without backup, your business will fail. I agree if there is no records why would I expect to see anything. You might want to do that because otherwise unless your user understands how to use the esc key to back out of an update, he'll end up in what seems to
Having such a mainform with employees will allow the user to use the right-click popup menu to filter the employees and easily find one(s) that needs to be updated. https://bytes.com/topic/access/answers/949219-subform-not-showing-when-there-no-data Tropical beaches and snow topped ski slopes Intersections of wires in circuitikz Unable to install a VM into another VM stat: modification timestamp of a file Finding a character from a OBP, Mar 6, 2013 #2 aattas Thread Starter Joined: Feb 27, 2013 Messages: 89 OBP, you are a life saver, thankyou very much.

But if you do not allow additions then it cannot show the empty record. Is there a word for "becomes empty"? Whenever you assign the value of a field to a non-variant, you must consider the possibility that the field may be null. How can I remove paint off my truck? 'Yeah but it's a dry heat' - reference to another film?
You create a relationship between Invoice.InvoiceID and InvoiceDetail.InvoiceID, with Referential Integrity enforced. When closing the form the user has two options: 1) Cancel, which will require to delete the record. 2) Save, what will trigger the code to validate the record and when nothing can be saved because no records exist. aattas, Mar 6, 2013 #4 This thread has been Locked and is not open to further replies.
This also requires a DELETE when there's a change of Type, but effectively the addition becomes an Update of an existing record and this approach saved me a lot of time No matter how familiar you think you are with them, always remember to take extra precaution when opening an email with attachments or links. Remove this join or change it to an outer join.
Then the user gets a filles subform and is able to check the appropriate loan types.
It gave the users lots of warnings and error messages but it never prevented the bad data from being saved. Bachatero, Recordset.RecordsetCount doesn't seem to work at my end. Even if ClientID is the primary key, the code is not safe: the primary key contains Null at a new record. Since these records don't match any record in the main form, these orphaned records are never displayed again.
When first creating the user, I have the subform set to visible = False. When this happens, only the subform control become visible, but not the form (which is empty this this is a new employee being entered). aattas, Mar 6, 2013 #3 aattas Thread Starter Joined: Feb 27, 2013 Messages: 89 OBP, thankyou very much, it worked like a charm.

May 7 '13 #10 reply Expert 2.5K+ P: 3,072 nico5038 An easy help for the insert you can use a query like: Expand|Select|Wrap|Line Numbers INSERTINTOtblLoanLink(PersNr,LoanType,ValidYN) SELECT123ASPersNr,tblLoantype.LoanType,tblLoantype.ValidYN,* FROMtblLoantype; By executing this I didn't have it undo the update. When you run a query, there is no loop involved. It is the ONLY event you have to use to trap validation errors. 2.

If so, then perhaps you have the "Data Entry" property set to YES. Solution Specify Is Null.
SHA-1 – Why is it hard to find a certificate collision? In the EmployeeType combobox's AfterUpdate event I check to see if the type selected was the type that needs this subform and if it is, then I make the subform visible. Your cache administrator is webmaster. Solutions (a) Use a Variant data type if you need to work with nulls. (b) Use the Nz() function to specify a value to use for Null.
I looked at the code I posted and noticed an error which might be causing the confusion. That's how he got to 10,000 lines. Tech Support Guy is completely free -- paid for by advertisers and donations. You can warn them all you want but the bad subform records are already saved.
