I am currently building a MS Access database as a project #Work.
The Database is fed with a huge, not sorted Table DataQueryExport, and the objective is to create a GUI that makes that huge table workable.
Now to the question:
I have a textfield Comment that is supposed to show a comment to a specific data entry WorkID. The WorkID Is stored in a seperate table called WorkID_Comments which is filled via SQL query. The Table WorkID_Commentshas 2 columns, WorkIDand Comment.
The GUI has a ComboBox WorkID_Combo, where you can select a specific WorkID from the main Table DataQueryExport. This exact value is what is supposed to be used as a reference to show the comment for that WorkID.
TL:DR; I need the Comment Box to show and store the Text I wrote for that Value selected in the ComboBox. How do I get the Textfield to show the Value from the Table WorkID_Comments.Comments where the Value in WorkID_Combo(View ComboBox) is the same as WorkID_Comments.WorkID
I apologize beforehand for any weird capitalizations, I am used to it, German is my main language.
Thank you for reading, I am thankful for any response.
Build a query in the query designer with your needed columns (If I understood it correctly: ID and the Comment).
Then go to your combobox and chose under properties recordsource table/query and your designed query.
Now you can specify which colums should be shown and use the ID as the value in the background.
Then bind another query to your form (here is the text you wrote as column) which is linked to the ID from the combox. Put a textbox in the form and use the column as source.

How to query combo box of only current record/row in Access data entry form?
(1 answer)
Closed 1 year ago.
I am trying to make a dependent drop down work with my database here but it is giving me a hard time for different reasons that I will explain.
This is what I have:
A form called "tblOTS" (split form based on an actual "tblOTS" table):
As well as a table called "tblAlphaCode":
When looking at the property sheet for the "Alpha Code" combobox (actually called "strOTSAlphaCode") on my tblOTS form, this is what I have:
The current SQL statement under "Row Source" for this strOTSAlphaCode is:
SELECT tblAlphaCode.strAlphaCode, tblAlphaCode.strCategory,
tblAlphaCode.ID, tblAlphaCode.numSortingOrder
FROM tblAlphaCode
ORDER BY tblAlphaCode.strCategory, tblAlphaCode.numSortingOrder;
Basically, when user select an Alpha code in the drop down from "tblOTS" form, it adds the ID of the tblAlphaCodes into the actual tblOTS record.
My goal is to have the user select first a "Category" (here FASTENERS/HARDWARE ...) when adding/modifying an OTS record, and then have the "Alpha Code" drop down dependent on what category was just selected.
I first tried to changed the SQL statement using a WHERE condition on the category field, based on the form category field itself:
SELECT tblAlphaCode.strAlphaCode, tblAlphaCode.strCategory, tblAlphaCode.ID, tblAlphaCode.numSortingOrder
FROM tblAlphaCode
WHERE (((tblAlphaCode.strCategory)=[Forms]![tblOTS]![strOTSCategory]))
ORDER BY tblAlphaCode.strCategory, tblAlphaCode.numSortingOrder;
And created a strOTSAlphaCode.requery in my Form_Current event to update it everytime.
However, it affects the whole form itself as my control source is directly affected by my Row Source in this instance, and the form looks like this:
You can see that the drop down is working beautifully, however, all the fields that do not have the same category as the current record that I work on (FASTENER <> HARDWARE here), are missing their Alpha code (the second record is missing "O-RING" compared to the first picture from this post); this behavior is problematic!
I tried to find workarounds by changing strOTSAlphaCode into a simple text box only containing the Alpha Code ID, added an unbound text box on top with dlookup function to find the actual alpha code related to this ID, and an unbound combobox in between with the exact same SQL statement inside the Row Source Property, that would update the strOTSAlphaCode with some VBA ... not ideal right?? Ahaha. This is why I believe there is a simpler way that I am not aware of, but also I would like to use a "search as you type" code for this combobox later on and this solution was making it very difficult.
How can I make this work? I believe the answer is a simple/different SQL statement to put in my Row Source property, that is probably something related to some type of JOIN statement? Or something else? I expect to write some VBA code to make all of this work flawlessly, but I want to make sure that I have the right SQL statement first.
Thank you June7;
Yes, the link you gave me ( this link ) states 2 solutions, and the second one is the one that I talked about when describing my problem:
for forms in Continuous or Datasheet view, include lookup table in form RecordSource, bind a textbox to descriptive field from lookup
table, position textbox on top of combobox, set textbox as Locked Yes
and TabStop No
So I guess, the answer is that I MUST have a textbox with dlookup setup for my case; I put it on "locked" so that if the user wants to change it by typing in it, he will first have to select the arrow. This will work with what I wanted to do
Cheers,
I created a database in Access and there are some type of records in some tables that requires a particular inserting, so I decided to use VBA to handle this.
The problem is that if i create a form with some controls which i want to refer and use their values as criteria for queries, the form is still a way to insert data. So the query works but the data i inserted are added directly from the form too, creating duplicates.
The question is, is there a way to create a form that has controls only for text input but does nothing to record , leaving inserting, deleting , updating all to queries in VBA?
I tried to put "no" on propriety "add records" in the form but it gets totally blank with no controls.
Your form must be unbound, i.e. its RecordSource must be empty.
Your form can be bound or not bound to a table / query.
This means that the controls on your form may be bound to a field of that table / query.
But you can also have controls in the same form which are not bound.
Example:
You can make a form in which the body has a list view of the records of the table. In this section the controls would be bound to a field.
In the header of the table instead you may have controls that are not bound and that could be used either to filter the records shown or to add new records. You may want to add records this way rather than let users insert data directly in order to add checks or do any other kind of processing before actually adding the data in a new record.
I have a temporary table that is created from a series of query with a VBA code. The name and number of fields in the table changes with the results of the queries.
Right now I simply open the table with DoCmd.OpenTable.
What I would like to do is display the table in a form so I can include some buttons for example to allow the user to export the table.
I tried a listbox but the formatting was not good and I can't add horizontal scroll bar to see all fields.
I tried a subform populated from the table, but it would not adapt to the changes of the table (fields and numbers).
Any Idea of what can I do next ?
the subform seems to be a good idea. When your table is ready to be shown, you can assign it to a subform object via Me.subFormName.SourceObject = "Table.tableName"
(of cource "subFormName" and "tableName" have to be replaced by the actual names of the subform and the table)
Background
I have two tables:
Projects
EmployeeID
Employee
EmployeeID
Name
I have a query I am basing a form on containing, among other items:
SELECT e.Name FROM Projects p JOIN Employee e ON e.EmployeeID=p.EmployeeID
When I make a form in Access based on this query, I can very easily display e.Name on my form because it is joined from the query.
My real example is of course considerably more complicated than this simple example. The above works fine for read-only queries and scales well. However I would like to use a Splitform view and this becomes very slow with many joins for even small numbers of recordsets. Considering a large percentage of my joins are simple like the above, I am hoping for a way to remove as many as possible.
On the form, e.Name will be read only and not be update-able.
Similar question
In this question I am able to successfully change a combo-box into a lookup. The accepted answer allows a combo box to control Projects.EmployeeID by displaying Employee.Name field in the combo box.
Possible work-arounds
I know one way I could do this is use a combo-box but disable it. This would look a bit weird since it'd have the drop down selector but not be selectable.
Alternatively, I could make it a completely unbound field and write VBA code to update the form each time the recordset changes by running quick queries, getting the text value I am searching for, and updating a label accordingly.
Neither of these are overly appealing, however.
Question
How can I display a single text field on an Access split-form which is the result of a very simple query lookup, based on an ID from the main table field?
You can use Dlookup to return this reference very simply
Construct a Dlookup formula like:
=DLookUp("Name", "Employee", "EmployeeID =" & "[EmployeeID]"
and use this as the ControlSource for the textbox.
Some notes:
The & is important as it binds the formula to the single record displayed on the form
[EmployeeID] refers to the current record displayed on the form. This assumes that "EmployeeID" is included in the query for the form, whether bound to the Projects table or included in the query
I have a table Prices:
ID -- primary key, autonumber long integer
PriceDate -- Date
Price - Currency
Quantity - Number, DECIMAL subtype
UnitPrice - Number, DECIMAL subtype (an update statement is run to keep this in synch with price and quantity, but it's just a convenience for indexing... probably it'll be replaced with an expression in my queries)
ItemNote - Text
NewStores_ID - long integer key, lookup to another table of stores
NewItems_ID - long integer key, lookup to another table of items
To enter prices for a given store on a given day, I would like to be able to select the store and date ONCE on a form, then enter the items individually in a datasheet. For reasons unexplained, this proves difficult.
I can create a subform binding everything but the store and price to a temp table TempPrices with the same structure as the original. Then I run the SQL statement
INSERT INTO Prices
(PriceDate,Price,Quantity,UnitPrice,Brand,ItemNote,NewStores_ID,NewItems_ID)
SELECT
PriceDate,Price,Quantity,Price/Quantity AS
UnitPrice,Brand,ItemNote,NewStores_ID,NewItems_ID)
FROM Temp_Prices;
This will feed all the new rows into the main table. But, when I want to set the store and date only once, I run into problems. I've tried using named parameters for date an store in the insert statement... which can cause a pop-up prompt, but I cannot bind it to a form control. I've tried binding an update statement for those fields in the temp table to a form... but it doesn't even show an option to bind a multi-row update.
How can I get this to work with a minimum of clumsy hackery? It seems like there ought to be a simple solution, and if I were using something like PHP or JDBC I'd just run an extra query.
Edit: changed storage type for Quantity and UnitPrice to Number, Decimal subtype in place of double float. Just so people won't cry about using a float in any proximity to currency. It doesn't pose a problem in my use, but there are enough people who have a knee-jerk reaction to that.
Edit 2: Form/Subform
I'm trying to structure this as a master form with a either fields for entering store name and date, or a subform for the same, then a subform mapping to the temporary table for entering pricing data. There is an action button to run the insert/update queries to dump the temp table into my main prices table and clear out the temp table. However, the problem is that I can't figure out how to get the date/store fields in the master (or subform) to bind to an insert/update value applied to all the new rows at once.
Edit 3: SQL Statements (for clarity)
INSERT INTO
PRICES(NewStores_ID,PriceDate,NewItems_ID,Brand,Price,Quantity,
UnitPrice,ItemNote)
SELECT
#MyStore_ID,#MyPriceDate,NewItems_ID,Brand,Price,Quantity,
Price/Quantity,ItemNote
FROM TempPrices;
UPDATE TempPrices SET PriceDate=#MyPriceDate,NewStores_ID=#MyStoreID;
For these queries, I cannot bind parameters for #MyStore_ID or #MyPriceDate to fields in any form. The queries don't show up as options when trying to link them to a form. I can run them and get popup boxes to input parameters, but that's not what I want.
This is the target I'm aiming at:
"I would like to be able to select the store and date ONCE on a form, then enter the items individually in a datasheet."
However, if you have a reason why you need to do it with a temp table and DML statements, then this suggestion will not be useful.
I created a Prices table with only 4 fields, then a query on that table which I used as the Record Source for a form, "fsubPrices":
SELECT p.ID, p.NewStores_ID, p.PriceDate, p.Price
FROM Prices AS p
ORDER BY p.NewStores_ID, p.PriceDate;
The form has text boxes (txtNewStores_ID, txtPriceDate, and txtPrice) bound to the similarly-named query fields. I set Enabled=Yes for txtPrice, and Enabled=No for the other two.
Then I created an unbound form "frmPrices", and in the form header added a combo box "cboStores" and a text box "txtPriceDate". The combo has Bound Column = 1 with this query for its Row Source:
SELECT l.Store_ID, l.Store_name FROM tblkupStores AS l ORDER BY l.Store_name;
Then I added fsubPrices as a subform control to the detail section of frmPrices. The tricky part is setting the Link Master/Child Fields. There is a "wizardy dialog thing", but it will only allow you to select from the available fields, and I needed to link controls on the main form with fields on the subform. To do that, I had to type what I wanted directly into the subform control's property sheet:
Link Child Fields......NewStores_ID;PriceDate
Link Master Fields.....cboStores;txtPriceDate
The result is ... choose a store and date combination in the main form ... any matching records are displayed in the subform. You can navigate to the "new record" in the subform to add records for that store/date combination. But the txtNewStores_ID and txtPriceDate controls don't show the updated values until the new record is saved.
I hope this is close to what you want. It's actually fairly quick and easy to create; not so easy to describe.
You can't really do that. You are always going to have one row being worked with at a time.
What you can do is simulate it by changing the form's Default View from "Single Form" to "Continuous Form" or perhaps "Data sheet" and making is a child(sub) form of a master form.
Then you can put the store and date on the Master form, and linking to the child form using the NewStores_ID and PriceDate fields.
