I have a relatively simple Access Form that I use to catalog items in a collection I have. It all works beautifully...most of the time. The one thing that I cannot seem to figure out this:
I have one control bound to a Multi-Value field in a table (yes, I know, I know...don't use Multi-Value fields). When editing this field via the Access Form control, I am able to add values and delete values, but if I try to delete ALL values in the field, I receive an error message advising that the record cannot be saved, and Access is not able to move on to the next control.
I've searched the internet for similar issues and found nothing. Anyone have any ideas? Thanks in advance.

I have a checklist that is used to perform QC audits. When a reviewer answers a question that requires an exception, a pop-up form will open with the correct exception detail already populated. They then have to provide some further information, which I have set-up in the format of a combobox for a field named 'Condition_Detail.' Some exceptions have only one condition that would be an option in the drop-down whereas others have multiple possible conditions, which is why I don't have that field automatically populated as well. I have a table of possible exceptions and conditions that I have used to create the combobox query. When the database was created, the field the 'Condition_Detail' combobox is dependent on was labeled 'Exception Detail' with a space and in my new table it is called 'Exception_Detail.' I did this because the old data and tables will eventually become irrelevant and I know that it is easier to write code with underscores instead of spaces. I include this information because I had to create a relationship between those two fields in the combobox query so that the database would know they are the same. When I test the database, the form opens as expected with the exceptions already populated (NOT in combobox format - the data appears as text on the form). The issue is that when I select the combobox, it is blank. If I answer the exact same question the same way to trigger the same exception to open in a new record, the combobox does have the correct data in it. I have tried to requery the field both when the form loads and after it updates. It still won't show the combobox values unless I trigger that the form open twice with the same detail populated. An additional piece of information that likely doesn't affect the problem is that the combobox is set-up as three columns so that I can populate two additional fields when the condition detail has been updated. I used the code below to populate that, which works perfectly when I can get the condition detail to appear in the combobox:
Private Sub Condition_Details_Change()
Me.Responsible_Position.Value = Me.Condition_Details.Column(2)
Me.Severity_Description.Value = Me.Condition_Details.Column(3)
End Sub
Thanks in advance for your help!
I figured it out. The relationship I created within the combo box query was unnecessary. The query was searching for values in the table that stored the actual responses/conditions instead of the table that stored the available response options. Because of this, once I had answered the question it knew what to look for, but in the wrong place. Setting up the combo box the usual way with the look-up control value in the form referenced as follows was sufficient to get the combo box to work properly.
Field: Exception_Text
Table: tblPreCloseExceptionDescEnc
Criteria: [Forms]![frmEncompassExceptions].[Form]![Exception Text]
I have a SQL Server that is ODBC into my Access which is being utilized as my front end. I created a column in SQL with a BIT data type and created a checkbox with the yes/no data type that uses my SQL Column as its control source. When I go into my form and try to change anything in there and update my tables, I get a writing error and it wont let me append the updates I'm trying to make. As soon as I delete the bit data type, and the check box, then I am able to again append information to my form. Does anyone know a solution or a way I could utilize the Boolean check boxes to report to my SQL Database so that I could track progress of an order, but still be able to append my records? Also if anyone knows why this is happening I would appreciate the information just for my own notes and understanding.
this image shows the column created in SQL Server
This image shows what it looks like in the ODBC table in Access
This image shows the control source I picked which is from a query that utilizes the names of the form comboboxes, text boxes, and hopefully check boxes
This is image shows what happens after I try to update and and close
Thanks
haven't done this for a long time, but the problem could be related to the numbers that are stored. yes/no in access = -1/0, in sqlsrvr = 1/0 (or similar). you could use an INT field in sqlsrvr which will then store whatever access sends (-1 or 0), or keep the BIT but don't use yes/no in access - create a custom yes/no table where yes=1 and no=0 (or whatever BIT needs) and use the custom table as a lookup table for that field which, when updated will send the appropriate value. hope that's all relevant and makes sense.
So I have been messing around with this and after a few other problems running through SQL, Cabinet Vision (our drafting software with a ancient access database) and crystal reports I came to realize that Access cannot accept null values.
So in my SQL Bit data type column I set the default value as 0 and didn't allow nulls. now it records all my check boxes as true or false. and I no longer have a write conflict.
This most commonly arises when a db is developed in Access and at some later date the tables are exported via ODBC to SQLServer. The Checkbox controls on the Access forms were probably placed there using the 'Available Fields' button on the Access 'Design' ribbon. Before getting into complicated solutions with T-SQL modifications to metadata etc, try simply deleting the checkbox control from the problem Access form. Insert an unbound checkbox to replace it, then use the the Properties dialog to set the relevant SQLServer field as the control source for that checkbox. Usually works.
I am trying to write an Microsoft Access query from a form with a multi value field being the criteria. The field I am trying to use is called Population and the field is represented in my database as a List Box that allows multiple values and it is in the Building table. The values it allows are the following:
"Singles";"Familes";"Families with Children";"Youth/Young Adults";"Veterans";
The form that I am creating is called HousingSearch.
I am trying to create a form which uses this field, so someone could use the list box and check off the values they want and click on the button which would open a query. I know having done this with single value fields the criteria in the query looks something like
[forms]![HousingSearch]![Building]![Population]
but if you try the same thing for a multi value field nothing is returned for the query. Any help would be appreciated.
From the information you have provided it seems that the phrase [Forms]![HousingSearch]![Building]![Population] are combining a request that starts with a form and then jumps to a table.
You are asking access to find data in a form but the information you're most likely trying to access is in a table. I don't quite understand what you're end result is but I think that you most likely want to refer to your information this way [Building]![Population]. Referring to your data this way makes access look at the table of [Building] and then into the field of [Population].
It's been a while since you posted, if you haven't cleared things up already I hope this helps.
this has me pretty confused and I can't find the answer anywhere else so thought I'd post here to see if anyone can help!
I have a form in an Access 2007 database with a subform (sfSubform) embedded in it. The subform control's SourceObject is set to be another form (fForm). fForm's RecordSource starts out as a table.
At one point I want to change the data displayed in the subform to the result of a SQL statement, so I use
sfSubform.Form.RecordSource = strSQL.
This works fine. However, if I ouput the name of the RecordSource for fForm after making this change, it still gives the name of the table that I orginially set.
Does sfSubform.Form.RecordSource not change the source of fForm? Is it a copy of fForm that is embedded in the control?
Hope all that makes sense.
The sub-form and the form each have their own record source (or are unbound). That's the whole point, actually -- the ability to present two different data sets. Typically the two forms have related record sources and this relationship is declared using Master/Child Link, but that also is optional according to the need.
So no, changing one won't cause the other to be changed.
I have an Access database that is used to store basic info in a table such as first and last name. How would I go about adding the functionality to lookup by last name?
Is there a way to type in the last name and then hit like F12 or something like this? Can someone please point me in the right direction or provide me a link?
SELECT tblPatient.LName AS [Last], tblPatient.FName AS [First]
FROM tblPatient
WHERE (((tblPatient.LName)=[Enter Last Name]));
How do I tie this into my form now?
I'd suggest you create a form, with a textbox 'search' at the top, then either a listbox or subform below to display results.
The listbox record source would be:
SELECT tblPatient.LName, tblPatient.FName
FROM tblPatient
WHERE tblPatient.LName LIKE Forms!myForm!search & '*';
You can either add a Search button, which requeries the listbox, or do the requery via the Change event of the search textbox. The later may be slow if you have a large number of records; if that's the case, you could check that at least 3 (?) characters have been entered before calling the requery.
You just need to create a query in which you put =[?] as the "last name" value.
When you open that view, you'll be asked to type in a lookup value for that field.
Not sure if this is what you are trying to archieve, though...
This is probably a bit overkill for what you want to do, but I assume that you want to perform a search by last name. You should be able to glean the information you need from this article:
Build a search criteria form
http://www.everythingaccess.com/tutorials.asp?ID=Build-a-search-criteria-form
You can create queries in Access if the user you're targeting with the searchability has Access themselves.
From the main Access UI (assuming Access 2007), go to the Create tab and then select the "Query Wizard." Here is an article on the subject.
Otherwise you can create a program and connect to the MDB/ACCDB file running the query programmatically.
Seeing you wish to look up a name and populate the form based on the name selected, I suggest you need a combobox. There is even a wizard for doing exactly what you want. To start, you will need a form bound to a table or query, that is a form with a Record Source.
Add a combobox to your form
Select :
Find a record on my form based on the value I select in my combobox
Select the ID (primary key), Last and First name fields.
Access will display an example, suggesting that you hide the Key (id) column. Accept this.
Choose a name and finish.
There are a few other small things that could be done for neatness, but you will end up with a form that find the record you want. In addition, the combo will autocomplete if you type in a few letter.
If this is an mde, which your subsequent post seems to suggest it is, there is little you can do wuth out the original file. However, you could try opening the database while keeping the shift key held down and see if that allows you to edit. If you cannot get the original and the shift does not work, you could try rescuing the data, if it, too, is stored in this file.
