Access subform datasheet table query

I have a subform which displays records in the datasheet view.  Two columns, Product and Amount, and roughly 20 rows.  It is populated using sql when I select Department from a listbox on the same form.  Data that is displayed in the subform is reviewed and if needed changed.  

Because the subform isn't bound to a table, how can I grab all of the records in the subform and write them to a table I have specified?  I'm trying to think of this in terms of "Select Product, Amount from subform" but cant get think of how to make this work.

You can use an update query.

Thanks, I get that much.  How do I reference the form as a table?

I don't understand.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

The subform displays a datasheet view which is populated with data.  I'm trying to figure out how to reference the datasheet in a query as the datasheet is unbound.  It is unbound because the table from which the datasheet is populated is not the same table that I'm trying to write back to.

This is what I'm trying to get work:
Private Sub Command51_Click()

Dim db As Database
Dim temptbl As TableDef

'subfrmProdSel is the subform object containing the datasheet

temptbl = subfrmProdSel

Set db = CurrentDb()

db.Execute ("insert into tblTempProdAlloc (Product_code, Product_name, alloc_amount) " & _
    "Select product_code, product_name, alloc_amount from temptbl ")
db.Close

End Sub

Open in new window

How are you populating the datasheet subform?

Another table
Forms!frmProductAllocation!subfrmProdSel.Form.RecordSource = "SELECT PRODUCT_NAME, ALLOC_AMOUNT FROM tblTempProd"

Forms!frmProductAllocation!subfrmProdSel.Form.Requery

I don't see how someone asking for more detail can be interpreted as ' no feasible solution' .

Clearly the subform IS bound; it is bound to the tblTempProd table via the query you posted.
So any additions or edits are in that table.

So you use a standard Append query to add to the the second table (table2)- change the sql to use your own names.

INSERT INTO table2 ( product_name, alloc_amount)
SELECT product_name, alloc_amount
FROM tblTempProd;
Save this as say qryAppend


You need to be sure you have saved the last new/changed record in the subform before you run the query.
If the code to run the append query is in the subform then you should do..
me.dirty = false
currentdb.execute "qryappend", dbfailonerror

But if you running the append query from the main form, say from a button,  then you can just set the focus to field in the main form first

me.anyfieldname.setfocus
currentdb.execute "qryappend", dbfailonerror

No feasible solution for referencing the datasheet directly in my sql statement.  That's all that I was getting at.  What I didn't realize was that when I set the recordsource via vba code (as opposed to setting the object properties in the dialog box) for the subform that it established a read/write relationship.  At first I had assumed a read-only relationship.  While "experimenting" with the datasheet I realized that changes in the datasheet modified the recordsource table.  I used this relationship to get the job done.  While I couldn't query the datasheet object directly, I could use the underlying recordsource relationship to assign a holding table and query the holding table.  

I'd consider myself a novice VBA user, but this is my first project where I've had to use a subform and have had no experience with this object and its methods.  I just needed to understand how the object worked.  Figured that out on my own.  Thanks for following up.

Yes, peter57r's explanation is helpful indeed.  To assist others reading this post I think it should be made clear that one cannot select data from a subform like you can with a list, combo or text box.  You must select the data from the bound source using either a query or an embedded sql statement.  

Peter - Thanks for your help.  Wish you would have come across my post 8 hours sooner.  Would have saved me a great deal of headache.  But that's how you learn I guess, by doing.
