Merging Two Tables And Totalling

Dec 13, 2006

Ok, I have a problem. I have two tables with different data pulled from two different areas, but that have the same type of information in them. I need them merged into one query or table so it can be exported into excel.

The problem is that one table has data only once (has a primary key, then things by building and grade). The other table has it's primary key, but then could have more then one building and grade combination (i.e. building 1050 grade 8 membership of 10 more then once becuase off another factor).

I need to merge this stuff by query of some kind into another query or table that totals all things with the same primary key, building and grade. So there is only one line for xxx-xxx building 1050 grade 8 with the grand total of membership for all.

How do I do that?

Generating A Query Using 4 Tables And Totalling One Of The Columns :S

Feb 1, 2006

Hi guys, I am trying to create a query collecting data from 4 tables as well
as calculating totals delivered but it's hurting my head trying to work out
all the joins can anyone help please?

The 4 tables are as follows:

Orders
=====
OrderNumber
CustomerName
CustomersRef

OrderDetails
=========
Order_Items_ID
OrderNumber
ItemNumber
Qty
ItemType
Description

Deliveries
=======
DeliveryNoteID
OrderNumber
Date

DeliveryDetails
==========
DeliveryDetailID
DeliveryNoteID
ItemNumber
QtyDelivered

The relationships are pretty straight forward, OrderNumber on Orders and
OrderDetails are linked as are DeliveryNoteID on Deliveries and Delivery
Details.

I want the query to list every single item for all orders as well calculating
how the quantity remaining to be delivered based on deliveries so far and Qty ordered.

So I want to create a report that pretty much just displays:

Orders.OrderNumber - Orders.CustomerName - Orders.Customer_Ref -
OrdersDetails.ItemNumber - OrdersDetails.Qty - OrdersDetails.ItemType -
OrdersDetails.ItemDescription - Deliveries.DeliveryNoteID - Deliveries.Date -
DeliveryDetails.TotalQuantityDelivered

Can this be done as one query or do I need to join two queries together?

It's hurting my head :(

Totalling Troubles- Help!

Apr 4, 2005

Hi,

I have hit a brick wall with my A-Level Access Project. Basically, I have a form for ordering where a user can select items from a combo box linked to a table that contains products. They then select the quantity and a subtotal is calculated for that particular item(s). By that I mean the subtotal generated is only for one selection from the combo box. Any subsequent selections have their own subtotals generated afterwards (I hope I'm not being too vague).
This is the form I am talking about:
http://img.photobucket.com/albums/v318/GOAT2G/FrmMakeOrder1.jpg

The thing I am having trouble with is the final box; "Order Total". I have no idea how to set it to sum all of the above Subtotals to equal an overall total. I will send anyone willing to help a copy of the database via email or something if they need it.

I would be immensely grateful for any help you can give.

Thanks,
Adam

Hi, I have been looking for some answear, but haven't find the proper one!!
I have a form containing a number of records showing the hours worked in format HH.MM at the end of the form I have the sum of the hours, but the result is not correct.
To make it simple to understand, actualy the total of hous for 11.55 and 11.14 gives me the result of 22.69 but the correct result should be 23.09 (23h and 09m and not 22h and 59m)
How can I get the right total???

How To Create A Totalling Query ?

Aug 23, 2005

Hi. I have a simple access table that contains details of our customers, and what products they have bought from us. Each row represents a product bought, and contains the customer details & the value of that product.

What I wish to do is create a report that lists these purchases, grouped by the client. That much I can do. However I also wish to sort the report by the total spend of the customer.

What I think I need to do is create a query that totals the "income" column for each customer, and then sort the report on that new figure.

All I cant work out, is how ?. Could someone please let me know how best to do this - small words please - my ambition exceeds my ability !.

Thanks all.

Simple Form Totalling Error

Sep 2, 2005

I am making a simple tabular form to use as a subform in another.

The form has a cbo box (cboItem_Name)
Quantity (txtQuantity)
Price (txtItem_Cost)
Extended Price (txtExtended_Price)

Selecting an item in the combo puts the price in txtItem_Cost. Default for Quantity is 1. Control Source for txtExtended_Price = [txtQuantity]*[txtItem_Cost] and gives me my extended price.

I have a control in the footer of the form called txtSub_Total. It's Control Source =SUM([txtExtended_Price]).
This Sub Total box generates the #error.

Can anyone tell me why? Do I need to do some other magic with my txtExtended_Price control instead of a simple calculation, like I have?

Thanks for any help you can give a novice.

Totalling Fields From A Subform In A Control

Jan 12, 2005

I have a control on my main form which attempts to total the amount from all subrecords on that record. For example, I have fields called ValueA and ValueB in the subform. If I have 5 subrecords in a record, then I want the control to sum all 10 fields (5 for ValueA +5 for ValueB). How can I do this?

Totalling Records Based On A Filtered Field

Oct 19, 2006

How do I calculate a filtered total from a field in a subform. It needs to be filtered according to [agreementID] and I would like to total the records in another field.

[agreementID] [assessment]
01-pmg18 $20,000
01-pmg18 $15,000
02-pmg18 $13,000
02-pmg18 $21,000

eg: I would like the total assessment for all 01-pmg18's and the total for all 02-pmg18 etc. Can I automate this so it recognizes and totals all assessments according to each unique agreement id group. Customers can have many 'batches" of agreementID's belonging to him. The 18 also refers to his ID number it is typed in. Thanking you in advance!

Is Null And Linked Tables

May 1, 2007

Hi

i have a slight problem with my reporting data base.

we have currently set, up a database, which has a number of linked tables.

the problem is that, when the macro is run, and the report is poulated, it is not reporting the true amount, in one of the fileds.

we have worked out that, you cant have a is null command with linked tables, becuase it will bring incomplete data, and the zero length must be set to yes.

is there a way round this, i not that offay, with SQL, but i am getting the concept of it.

also, we have discovered it is the imported data, i.e. from another data base that seems to be the culprit. Is there something i can do to transform the data to bring me the count of null values in a partucular field?

many thanks andrea

Query On Tables With Null Values

Nov 9, 2005

Hi,
I have a problem with one of my query, the query has 2 tables, the secondary field from Table2 is linked to the primary field of table1.
The primary field Doesn't allow null Value
The Secondary Field does allow null value which means that the Data in table 1 only concern Some of Table2's Data.
If I run the query with the two tables I can only see the records with the secondary field with no Null Value.
Is it possible to get the query Showing All the records of table1 2 and Table1 even if Table1 has no values?

Tables :: Two Part Primary Key With One Null Value

Jun 25, 2013

I have just inherited a database that currently has no primary key set up. I wanted to add a two part primary key, but have run into a couple problems. The purpose of the database is to keep track of parts that have come back for repair. I wanted to set the key up to be a combination of the call number and the part serial number. I should always have a serial number, but the serial number can be in the table more than once, as it could have needed repaired more than once. I will normally have a call number for each record.

However, the call number could be repeated more than once, if more than one part came in on the call. The combination between call number and serial number should always be unique (each time a part comes in, it should be on a different call). My problem is arising, when a part is just pulled off the shelf of the factory and sent in for an upgrade. In a case like that, there is no call number. However, a serial number will never come in more than once without a call number.

So the combination of call number and serial number should still remain unique. When I try to set this up in the database, it tells me that the primary key cannot contain a null value (referring to the times that a serial number comes in without a call number). I want to get this set up so that the people entering data in the database will not be able to enter the call number, serial number combination more than once. How can I do this if one part of the primary key can be null?

Tables :: Append Query Not Working / Null Values?

Sep 24, 2014

I have an append query created to add files to a table from an imported excel file. The table to which I am appending (SubTBL) has a field names Observation. This field is not required. There is a relationship to another table (ObservationTBL) which has 3 records. The information I am trying to append includes 7000 records, about 4000 have observations assigned and they match the information in the ObservationTBL. The remaining 3000 have blank records for observation. When I run the append query, only those with observations are appended. The rest are not added because of "key violations". I removed the relationship between the ObservationTBL and the SubTBL and the append query runs. Then when I try to re-do the relationship it fails "Violates referential integrity rules".To be clear:

1. The records without an observation are blank. (There are other fields in this append that have blank fields also and they are not causing any problems)
2. The field observation is NOT set to required.

Is it not allowing Null records?

Tables :: Numbers / Text And Null All In One Field Linked From Excel

Jan 11, 2013

I know you can't store text in a numeric field but I always thought you could store numbers in a text field - provided you didn't need to do any calculations on them. My problem is as follows:

I receive an Excel 2003 spreadsheet once a month, which I save to a specific filename/location overwriting the previous file. My Access 2003 database uses this as a linked table and (among other things) runs an append query to add the new data onto an existing table.

We have now added a new column called Reference in the spreadsheet. Often, this will be empty, but it could contain numbers or text. This is the first month I have received it and most entries are blank (including the first row) but further down there are some numeric values.

So I added a new Reference field to my main table and set it to text. Then I amended the append query to include the new field. But when I run it I get the error "Numeric field overflow". If I take that column back out of the query, it runs fine, so that's definitely the offending data. And when I open the linked table in Excel and scroll down to where I should see the reference numbers, I see #Num! So it looks to me like it doesn't recognise numbers as text.

Things I've already tried

In Excel, I formatted all the Reference cells as text.

That didn't work, so next I added a dummy record at the top of the Excel file (just under the headings), with zeroes in the numeric columns and 'X's in the text columns including Reference.

But that doesn't work either. Given the above circumstances, what's the best way to proceed with this?

Tables :: Setting Primary Keys To More Than One Field In Table / But They Cannot Have Null Values

Nov 30, 2012

Access 2010..One organization that we work with provides us with a block of numbers for each of the two types of contract products we order from them; we do order non-contract stuff from them also.The block of numbers are the same (i.e. 20000 to 30000 this year) for each of the two products. This means that each product can have the number 20000, for example. We call this the Tracking Number. If it is one of these products, we need to select the Contract Number.

For all other one off orders we have with them, we assign our own Tracking Number starting with 00001. This Tracking Number cannot duplicate unless it is one of the aforementioned two products.Both the Tracking Number and Contract Number are in the same table. The user selects the Contract Number from a form (connected to the Contract Number table that has all the details on the contract) and the Contract Number is populated in the same table that has the Tracking Number.Each order must have a Tracking Number (no null)..Not all orders need a Contract Number (null okay).The Tracking Number and Contract Number combination cannot duplicate.I tried setting the primary keys to more than one field in the table, but they cannot have null values.

If not... I have been working on Plan B.... an AfterUpdate on the form (either the form or a field... don't know yet) that looks at a query that only has results if there are duplicate values.

Modules & VBA :: Switch Function - A Null Makes Whole Column Null

Nov 16, 2014

I do not understand what is happening here. I have foll0wing line in a calculated query field:

m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010

this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.

But if I do this:

m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example

then the entire column is set to Null

Totalling Columns & Rows Into Columns

Mar 22, 2007

I'm affraid my confusing topic title is an indicator of how confused I am by this. I can't even understand the variables well enough to fully utilize Access Help or the Search function here...

What I have is a database hat has column headers that look something like this:
Customer_Name, Order_Date, Qty_Ord, Unit_Price, Total_Price

What I'm trying to get is a query output that will have

Customer_Name, Total Orders (in Dollars) for January, Total Orders (in Dollars) for February, Total Orders (in Dollars) for March, etc.

I've been able to set it up to SUM for one month, but not multiples.

I know I'm totally lame (for proof read any of my previous posts) but you guys totally bailed me out the other time I asked a lame question.

Thanks in advance!
