Hi Experts,

Can you please help me with the following query. Not sure why it isn't working.

UPDATE tblfinancialtransactions
SET tblfinancialtransactions.TransactionAmount =
SELECT Sum(tblFeeSchedule.Fees) AS SumOfFees
FROM (tblClassProducts
   INNER JOIN (tblClassMeeting
   INNER JOIN (tblAttendance
   INNER JOIN (tblFinancialTransactions
   INNER JOIN tblInvoiceLineItems
     ON tblFinancialTransactions.TransactionID = tblInvoiceLineItems.TransactionID)
     ON tblAttendance.AttendanceID = tblInvoiceLineItems.AttendanceID)
     ON tblClassMeeting.ClassMeetingID = tblAttendance.ClassMeetingID)
     ON tblClassProducts.ClassProductID = tblClassMeeting.ClassProductID)
   INNER JOIN tblFeeSchedule
     ON tblClassProducts.ClassFeeID = tblFeeSchedule.ClassFeeID
HAVING (((tblInvoiceLineItems.TransactionID)=42))
WHERE (((tblfinancialtransactions.transactionID)=42));

It would be good if you can post a sample db having the tables included in the SQL query you posted. Include as well the Update query that you design for this.
Other objects like forms, reports, etc. may not be included.

How you are running this query? is it being run from a front end like a webpage or any other app or you are running it within Access?

If a front end is being used then you should check the permissions to the db.

If the database is on a network drive where multiple users can access it then  locking machanisin can be a problem too.

If none of the above then you might need to look at the joining tbles in sub query if all of them have the unique index creted. if even one table is without a unique index then it might be a problem.

My experience is not very good with Access when it comes to writing a complex update query.

If you like, you may want to achieve it in 2 steps.

1 - First Create a table (Make Table query) from the sub query you are using. - Complex logic will be turned into a plane table.
2 - Use that created table to update the actual table.

Hi Ed and Tabish,

I'm trying to create an update query to:
1. input into the financial transaction table the TotalAmount; by
2. summing up the line items in the tblInvoiceLineItems; and that
3. Each line items correspond to the transactionid on the form.

If you take a look at the frmInvoice and InvoiceLineItems table for example, what you'll see is:
1. TransactionID = 42
2. In InvoiceLineItem there are 10 lines with different AttendanceID.
3. AttendanceID indicates the attendance a student have taken in a particular class.
4. The classes student attends may vary in fees so query needs to check against AttendanceID for fees to be incorporated into the total amount.

Intended structure of the query.
1. Query to note TransactionID then
2. Go to tblInvoiceLineItems and grab all AttendanceID belonging to the TransactionID
3. Lookup the  fees from tblFeeSchedule that correspond to the AttendanceID
4. Add to find total amount.
5. Input this total amount into tblFinancialTransaction in the field TransactionAmount where TransactionID matches  that in step1.

Hope that clarifies what i'm trying to do.

To test this code, create a button in your frmInvoice. In the click event of the button, copy and paste the code below:

DoCmd.RunSQL "UPDATE tblFinancialTransaction SET tblFinancialTransaction.TransactionAmount= [Forms]![frmInvoice]![txtTotal]
WHERE (((tblFinancialTransaction.ID)=[Forms]![frmInvoice]![TransactionID]));"

The said code will put the Total amount into TransactionAmount of tblFinancialTransaction where the TransactionID is equal to TransactionID in frmInvoice.

Let me know whatever error that comes if ever there is.

I forgot to mention that I just assumed txtTotal as the field name of the text box that display the Total in frmInvoice.

Theres also another way to do it:
1. Create a new query and display it in SQL View.
2. Copy and paste the SQL statement below:
UPDATE tblFinancialTransaction SET tblFinancialTransaction.TransactionAmount= [Forms]![frmInvoice]![txtTotal]
WHERE (((tblFinancialTransaction.ID)=[Forms]![frmInvoice]![TransactionID]));
3. Name the query as qryUpdateTransactionAmount
4. On the click event of the button in frmInvoice, write this code:
DoCmd.OpenQuery "qryUpdateTransactionAmount"

Yeap. So if it is in the subform, change this part of the code
[Forms]![frmInvoice]![txtTotal]  into


For the txtTotal, see what is the name of that textbox in the property window.
