Access 2013 query only pulls the first record - sql

i'm hopeing someone will be able to solve this. I have a combo box which shows the records that are available to view. Upon selecting a record, my query updates without any problem. I tried to use this query within a subform however, for some reason, only the first record in the data set is shown upon selection. When I select anyting else from the available options, the subform doesn't change. However, when i re-select the first record, it shows.
The weird thing is, that when I change the drop down box to say the 2nd record & run the query itself, the desired record shows within the query designer.
To explain further: the combo box is called searchByAcc_cb. This is set so that it retrieves the account name & various other fields from the same table. Below that, there is a subform which is set to requery once another account from the drop down box is selected. When I select the 1st account, the record shows. However, upon selecting the 2nd account, 3rd, etc, nothing shows. I can then re-select the 1st record & i see the account information - so i know it's not a problem with the form updating.
The other strange thing is that upon selecting another account within the drop down box & then running the query from the query designer, the account information is retrieved for the 2nd / 3rd 4th record within the datasheet view. So, i know it isn't a problem with the query.
Any ideas on how to resolve? I've tried deleting the subform & re-inserting it (ensuring that the names match).

For anyone else struggeling with the same problem, I managed to resolve it: You need to delete any reference to the child / master fields within the subforms properties.

My recordset returns only one record even though there are more one record in Microsoft Access

I am creating a form that loads all the information from the Activity_Table into the form. So basically when the user chooses the name of the Company from the Company_Name drop down, and selects the site from the Site_Name combo box, it is supposed to return the values from that site and put them into the form.
Basically one site can appear more than once in the Activity_Table. Yet, whenever the user selects the name of the site, it only returns one record. To make sure of this, I used the .Recordcount method to check how many records that will be retrieved.
So when you check the Activity table, the Site "Accra Mall - 630kva Gen 2 " appears 4 times, yet when you check the recordcount, it only says it appears Once. So because of this, I cannot move either forward or backwards to either the next or previous record.
To make sure that there was nothing wrong with my sql, I run the query in the Query Design and it produced all 4 records of "Accra Mall - 630kva Gen 2".
So there is nothing wrong with the sql statement. Can anyone help me out please?
This is when I choose the name of the site
We can see that it returns only One record here
Yet this is the amount of records it's supposed to produce(This was when I tried the sql code in the query design tab. It returns 4 records, Not 1). So the recordcount is supposed to be 4. Not One.
this is when I tried the sql to in the previous picture.
If I replicated your problem correctly then the answer is to set Data-Entry to no. Check your form properties. Under the data tab there is a data-entry property. set data-entry to no. From microsoft at https://support.microsoft.com/en-us/office/dataentry-property-f4236759-27f6-4fcd-abb0-4aa4acd8fe87 we get an explanation:
You can use the DataEntry property to specify whether a bound form opens to allow data entry only. The Data Entry property doesn't determine whether records can be added; it only determines whether existing records are displayed. Read/write Boolean.

How to display out of list items in a combobox?

I have a tbl_ProjectList that includes the project's Name and End Date.
A qry_cboProject queries this table to only display projects in a combobox on Subform A where the End Date is after the selected date on Subform B, both on Mainform C.
On Subform A, a macro copies (INSERT INTO SQL) projects from Subform B's previous months into the new months. However, if an out-of-date project gets copied over to a new month, the combobox field would be empty for that record, even though the Key exists on the back-end.
I've tried playing with the combobox's properties on Subform A by changing the Bound Column, Column Count, Column Widths, and Limit To List, but am only able to get the out-of-date project to display by its Key, rather than its Name.
The front-end reasoning for this macro is that employees do not have to repetitively select the same projects for each month, and employees already working on out-of-date projects may still need to put in some hours to close out the project.
Does anyone have any suggestions? Thank you in advance!
The order in which fields show up in you combo box depends on how the control source is querying the information i.e. to get name and not the key to show up in a combobox using the a control source query like the following:
SELECT Key, Name FROM tbl_ProjectList
You would need to set the following attributes:
Column Count: 2
Column Width: 0"; 2"
Bound Column: 1
It sounds like you may need to requery the control source as well. This should cause all the information to update.
#Parfait - apologies for not describing my problem in more detail. There are multiple subforms on one main form to allow the user to select a date in one subform, which populates projects on a second subform and responsibilities on a third subform.
Jeffrey's suggestion made me realize that the underlying query to the combobox should be adjusted for projects that are carried over into new months, where a foreign key exists in the underlying tbl_ProjectUserEntry
Therefore, I added a WHERE criteria to the query, which uses a DLookUp function to see if the foreign key exists:
DLookUp("[DateID]","tbl_ProjectUserEntry","[DateID] =" & Forms.frm_UserEntry.tbDateID) IS NOT NULL
frm_UserEntry is the main form..
Again, apologies for my brief description to a complex problem.

Combobox Running Code/Query throwing "Recordset is not updateable"

When I click the Combobox, the dropdown list is populated, yet when I try to click on an option it says "Recordset is not updateable".. I have tried to read up on this error yet can't identify the issue behind this. The joins aren't complicated and it has worked before. The query source for the AwardsSubFrm is attached:
Anyone know how to fix this?
The image of the query design indicates your record source is a GROUP BY query. The recordset from any GROUP BY query is never updateable. You can verify that point by opening the query in Datasheet View of the query designer and confirm Access won't let you change any of the values.
I don't know what the fix is for your situation, but you need something other than just a GROUP BY query. Perhaps a subform whose record source contains the table rows you want to update, and link it to the main form so it displays those records which are related to the current main form row.

MSAccess: Change in subform recordsource causes loss of LinkChildFields binding

I have a problem that Im completely stumped by. Or rather, I have a work-around that is messy and I don't understand why what I want to do doesn't work:
I have a mainform / subform nest. The subform is linked by master/child fields (neither form is editable- so Im using the recordsource field directly rather than a separate control). The subform is a continuous form; so the subform displays the records related to the master in the mainform when the current record changes. The subform is based on a query- there are no parameters or filters being applied- the query presents the recordset exactly as needed. This all works perfectly (in that when the record of the mainform changes, so to do the related subform records).
Problem arises when I want the subform to be based on a different a different query (ie based on different tables)- but with the same unique-key (the 'ID') and fields as the original query. The queries all work fine, and displaying them in the form works fine.
The issue arises when I change the recordsource of the subform (so from QueryA to QueryB). The records the subform are correct (ie the query results are displayed as expected)- but the LinkChildFields is no longer functioning: the subform no longer shows the related records from the query- it displays them all. In other words, the form displays the entire recordset as if I had no LinkChild / LinkMaster set.
So, the code in the AfterUpdate event of the toggle control in the MainForm is ;
Private Sub optActRep_AfterUpdate()
Select Case Me.optActRep
Case 1
MainFormSubFormControl.Form.RecordSource = "QueryA"
Case 2
MainFormSubFormControl.Form.RecordSource = "QueryB"
End Select
Ive debugged and the property 'linkchldfields' is still set correctly ('ID'). Ive tried setting these to vbNullString before the recordsource update and resetting after the recordsource update (same issue). The odd thing is if I update the linkchildfield property in the mainform (in the Current Event)- then it works and seems to fire. So,
Debug.print Me!Subform.LinkChildFields
correctly returns 'ID'. The only way I can make it fire is by coding;
Me!Subform.LinkChildFields = "ID"
into the Current event of the Mainform (ie so that every time the MainForm record changes, the correct QueryB record is displayed)... even though Im only setting the property to what my debug is telling me it is already set to. Its as if it no longer fires.
Very confused.
Access continues to do the daftest things.
Nothing to do with the form setup at all. The underlying query (QueryB) was based on a Crosstab query. Whilst the query worked fine independently of the form (including when directly using the query as the forms record source), it obviously didnt like using the product of one of the fields as the Unique key (even though it was the same format type and Grouped / Row rather than being a cross-tab field).
I changed the crosstab part of the query to a Grouped query (using IIF & Sum to manually create the Crosstab-equivalent field values) and the form now works fine.
My lesson learnt- don't use Crosstab queries! Apologies for the red-herring.

Apologies for the late reply, I only found this thread when I encountered problems similar to yours. I'm not sure the Crosstab query is the cause of your problem.
I can set LinkMasterFields to be either a column name or a control name.
I can only set LinkChildFields to be a column name, setting it to a control name does NOT work. Ouch.
You can change LinkChildFields in the sub-form control either in Design View or via VBA, but in many cases Access continues to use the previous value even though it displays the new value. This is true for sub-forms whose record source is either a table or a simple two table query. I do not have the time or the patience to characterise this problem any further. Sorry !
My solution is to set LinkChildFields in the sub-form control to a value e.g 'ID' and then create an alias with that name in each and every record source used by my different sub-forms. Then you only need to change the Source Object when you switch sub-forms.
Hope this helps !

How to get min/max values on form that returns multiple records

I've got a form that returns multiple records from a table. Each of these records has a field indicating what the measurement was and the measurement's value. My form's record source pulls the appropriate ID's set of measurements and values, and then I want to write each of these measurements to different text boxes on the form.
The problem is that I'm also keeping track of the date this data was updated, and want to include only the data pulled based on the "date updated" selected at the top of the form.
When I go to pull the measurement value into a text box (with something like max(iif(Measurement="Acidity", [Value],[Null])) I get #Error all down my form. This had been working earlier today, and as I've been developing the form something changed and now it no longer works (everything but the date returned is saying #Error). I've set it to Requery when the form loads and whenever the date selected is changed.
EDIT:
This form is actually a subform of another main form. The main form has a control called MemberID which a user can use to select the Member they want information about. This is based on a query that pulls from a table the information related to that MemberID (one row per MemberID). When the form loads, the query behind the main form needs to be requeried to get the data for the selected MemberID.
Then there is this subform causing the problems. On this subform is a "Data Updated" drop down box, which lists the possible dates that the data was updated. When one chooses a particular "Data updated" in the drop down box, this chooses the latest data for all the data measures up to that date selected. This means the form's record source pulls about 10 records in my case.
Then, on this subform I try to layout these 10 records' values in different text boxes. So, in my acidity case above, I would say iif(Measurement="Acidity", [Value], Null). Because there are 10 rows returned, I will end up with 9 Nulls and 1 value, and to get that value I use the max function, so the text box's control source reads: max(iif(Measurement="Acidity",[Value],Null)).
The strange thing is this code was working this morning, until later this afternoon when I was filling in the remaining text boxes with similar code, and then it stopped working. I had also renamed the boxes from Text71 to more relevant names, but none of these are referenced in the code.
