Values Changing On Import Or Update
Oct 21, 2005
Can anyone help -
I am importing an Ascii text file with decimal numbers ie (144392.26). the receiving field is defined as double with decimals set to auto. I have tried many other formats such as fixed 2 decimals, or Currency 2 decimals. In all cases the data has changed from its original value to 144392.265625 which of course rounds to 144392.27 on all reports. If I use a link to the same Ascii file the data retains its original value when it is appended to an empty table. But ... When I try to use that correct value in the appended table to update another table it again converts the amount to multiple decimals and may increase by more than .01.
Is there away around this problem.

I have a query with an INNER JOIN and ORDER BY that is working great. Now, using the same JOIN, I need to update values in one table with the values in another. I thought it would be simple until I learned you can't do an ORDER BY with an UPDATE. Is there another way to achieve the same result? If you remove the 'ORDER BY', the statement below doesn't produce an error but the results are not correct:
UPDATE TableA INNER JOIN TableB ON (Left(TableA.CDN,6))=(TableB.CDN)
SET TableA.HCC = TableB.HCC
WHERE TableB.HCC Like '241*' AND TableB.BBB = 'X' AND TableA.CCC = "1234" AND TableA.HCC IS NOT NULL
ORDER BY TableB.HCC, TableA.CDN;

I am setting up a db for a ecomm site and the vendor prices are in 4 different currencies. I currently have the price fields data type as a "number" (long integer). Can the data type "currency" handle different currencies all in one table? Do I need to set up a seperate price table for all the products in each currency? Any help is appreciated.

G'day,
I preface this question as most newbies do. I have just started using Access(2000) and have built rebuilt/converted from DOS a database for a basketball club. I did start from scratch and just inported the table data.
I have already made a number of forms and subforms, e.g. searching for a player displays all the other players in that team and displays the team staff from the relevant tables. So I understands the concepts.
What I have tried to do, and succeeded in part is to populate some of the fields of the Player Account records from the Fees table. I managed to do a query from the Fees table for this using a drop down for the FeeCode, which fills in the Fee Description and Fee Amount. However if I change the Fee Amount it changes all of the fee amounts for that Fee Code type. (I think I solved this myself as it is a query and that is what it should do, correct me if I am wrong). Note that all of the retrieved data is static except for the Fee Payment, which can be different amounts, this is where it changes the source. Also as it is a query I think , the retrieved data just shows on the screen and doesn't get written to the Accounts table (not the description though).
So I have obviously gone about this the wrong way and rebuilt the Accounts trying to use lookups. Here is my problem (finally you say). I cannot get the default value to lookup the fee table based on the fee code. Note I have not started on the VB side yet so please be easy on me. There is a drop down box for Fees Charged but this lists nothing, so like the query before nothing gets written to the Accounts table.
I think (maybe I don't) understand the lookup thing as I used an old (DOS) database before and did the same thing and was able to change the default value just for that account. i.e. lookup the table>field where the fee code is = to this. I have tried the subform wizard a few times but just cant get it right.
Should the lookup be in the table field or the subform. Am I on the right track and if so how do I get the retrieved info from the Fees table into the Accounts table. My end result should be something like this.
Fee Code(lookupFees - write to accounts), Description (lookupFees - display only), Fee Charged(lookupFees - write to accounts), Fees Paid(lookupfees - modify write to Accounts), Date(Accounts), Receipt Number(Accounts).
Thanks for taking the time to read this, I have tried to give as much information and hope I haven't given too much.
Regards
DrF :)

Hi,
This query will allow me to view payments that are made between 2 dates. I would like to know how to flip the query around so that it gives me the payments that have not been made. I think this would be described as returning the null values?
The SQL code i have at the momnet is:
SELECT download20060602.Date, download20060602.Description, download20060602.Amount, Members.FirstName, Members.[Mid Name], Members.Surname, Members.[Memb No]
FROM Members LEFT JOIN download20060602 ON Members.description = download20060602.Description
WHERE (((download20060602.Date) Between [Enter Start Date] And [Enter End Date]));
Any help or ideas would be fantastic.
Cheers
Phill

i have a temporary table which is created by importing an excel file
some extra fields are then added to the table using sql vb code for example
strSQL = "ALTER TABLE [TBL_TmpSubmission] ADD COLUMN [EnergyUnit] TEXT;"
CurrentProject.Connection.Execute strSQL
these fields are later populated conditionally using an update exectuted again from vb code
If Me.cboProgram.Column(0) < 3 Then
strSQL = "UPDATE TBL_TmpSubmission SET EnergyUnit = 'GWh'"
Else
strSQL = "UPDATE TBL_TmpSubmission SET EnergyUnit = 'CarbonTonne'"
End If
CurrentProject.Connection.Execute strSQL
the problem is that this field now has a memo data type, this is a problem because i need to write a query which uses this field in a table join and access won't let you join on the memo type
anyone know why this might happen? for the time being i'm going to try and fudge this by using a further ddl statement to change the data type back to text but i'd rather know whats going on here

I have a simple add form that will add an entry to one of two tables: Box 1-1, or Box 1-2.
They have the exact same fields. In the add form, I want the user to specify a Rack field and a Box field. Box 1-1 would be Rack 1, Box 1. Box 1-2 would be Rack 1, Box 2 (there will be more tables later, but just using two for now until I get it working).
But right now my form always adds to the table Box 1-1 - I can't get it to switch.
I've added the code I have so far below. The first part is what I'm having trouble with, the second part just uses a Submit button to add a new record - I'm just including it in case it's interfering in some way I'm not seeing. I'm running Access 2007.
Code:
Private Sub Switch_BeforeUpdate()
If Me.Rack.Value = "1" And Me.Box.Value = "1" Then
Form_Add.RecordSource = "Box 1-1"
ElseIf Me.Rack.Value = "1" And Me.Box.Value = "2" Then
Form_Add.RecordSource = "Box 1-2"
[Code] ...

Currently I have a calculated field in my table; however, under certain circumstances I need to change the value to another value which is not related to the calculation. I understand that the calculated fields are read only (why is that?), so I was wondering if there was any way to change values within a calculated column without actually changing the expression itself.

i have an update query that looks for a product number, updates the cost, and re-calculates the price in two columns based on the salesman's margins. the problem i am having is that it seems to be hit and miss on the first run. if you run it again, it runs the calculations on all the fields. (it has to check / recalculate 16,000 rows.) should this query have vba to make it loop thru the table.
here is the basic layout of the query:
table 1 is newproductq
table 2 is Products
Field: PriceIn
Table: newproductq
Update To: [Products].[Cost]
UNITS
newproductq
[PriceIn]/((100-[Margin])/100)
PIECES
newproductq
[PriceIn]/((100-[BrokenMargin]/100)

Hi all,
I use an Excel import to update tabel 'deelnemer'. This works oke BUT when user 'x' has a linked field in tabel 'B' the import fails due to RI (I think..)
How can I make it so in this code that the user record is updated and can I restore the RI (otherwise my forms won't work..)
This is the code I use for importing the Excel file:
DoCmd.CopyObject , "Deelnemer_copy", acTable, "Deelnemer"
DoCmd.SetWarnings False
DoCmd.RunSQL "Delete * from deelnemer"
DoCmd.SetWarnings True
ImportFile = Application.CurrentProject.Path & "Deelnemer.xls"
DoCmd.TransferSpreadsheet acImport, acSpreadsheetTypeExcel3, "Deelnemer", ImportFile, True
Please help me on this, breaking my head over it and I'm newbie on all this..
Thanks in advance !

Hello All,
I currently have a macro that imports data from a spreadsheet and then a query that adds the data into the main table.
But when I want to import new data it deletes the old data out of the table and inserts new data. How can I adjust the query so that it "updates" the new data into the table instead of deleting and then adding?
Another problem is empty records, is there a way of importing data where field 1 has data?
Any help would be great.
Thanks.

Hi there
I have a spreadsheet that I have successfuly imported into Access but now I would like to maintain it, update/append/delete records etc.
The spreadsheet is produced weekly and Intend to import it into my Access database on a weekly basis there are around 20,500 records and 15 Fields. I have kept the Field names in Access the same as the spreadsheet, except that the Access table has an ID field with PK and autonum. There are no other tables involved, it should just be a straight import update append ...but how?
I am looking for the best way to approach carryingout a regular update, is it best to bring the new import into a Temp table? and then carry out the analysis of what has been changed, deleted or added?
Also the queries to do this, how exactly do you get a query to scan through all of these rows and columns.
one last thing is it possible to create a table during the update/append process that will log all of the changes or flag the records using A=Append, D=Deleted U=Updated...
I've tried looking at various forums but mostly all I find is people with similar problems and no definitinve answer.
thanks

I'm trying to import/merge/update a table from an xml file.To import I'm using the following code:
Code:
Private Sub Command0_Click()
Const acAppendData = 2
Set objAccess = CreateObject("Access.Application")
objAccess.OpenCurrentDatabase "DATABASE LOCATION"
objAccess.ImportXML "HTTP OF XML FILE", acAppendData
End Sub
This works perfectly to import new records, however what I also need it to do is merge/update the data. So the xml file will contain the correct data and any amendments need to be made to the Access table.

I have a database where two tables contain information that I need to update based on the 4 right most digits of a field. There are only 11 values that will need to be updated out of a large list of values. I'm not quite sure how to set up the update query so that I can do this.

I have a workbook which has links to access to import data. I have to have the information in Excel for a couple reasons:
1.) Many of our customers don't have Access.
2.) The customers use a "discount calculator" to apply their own discounts.
They also use it to then apply their own margin mark ups to be able to then use to quote to their customers. So a static report/pdf for them to look at doesn't work.
I've begun to create links from a number of queries in Access, which work fine. My problem is when I go to update the data. I'm not getting the following error coming up:
The database definitely hasn't moved. And I've run the queries in q, and there aren't any problems there. I've looked this error up and I'm seeing that it could mean that I've got some corruption going on.
Before I hit my main q, I should also note: I'm running all of this on a Citrix network. I should also note that it's a consulting gig. Once I'm done, I won't be available to fix major issues like this.

I have a huge table with transaction dates. I need to slice and dice
this data (sum, %'s, etc), but group by FY. Our fiscal year is from
7/1 thru 6/1.
For example:
1/8/2004 = FY 2004,
8/12/2004 = FY 2005,
2/3/2006 = FY 2006
THEN . . . . I need to also isolate certain periods, for example July-
March for YTD (year-to-date) analysis and compare YTD of 2006 with that
of 2005.
What do you suggest? Many thanks.

Hi
I have an access database, with around 36000 records. In one table, I need to add something to the values already in the field. Like:
Value in field:
image1.gif
image2.jpg
and so on
I need to change this value to:
images/image1.gif
images/image2.jpg
and so on for all the records.
There are 3 fields like this, each with around 30000 records.
Is there an easy way to do this? Other than copy the images ?
Thanks

I am developing an access db where employees are allowed to load tools from a tool store.
I have three tables: tblEmployee, tblTool, tblOnLoan.
tblTool includes a field "QtyOnHand" which is the quantity of a particular tool in store available to be loaned.
tblOnLoan is used to record which employee has what tools on loan.
When an employee loans a tool i need to be able to reduce the QtyOnHand of the tool and record the loan details in tblOnLoan.
When the employee returns the tool i need to increas the QtyOnHand of the tool and record the return against the original loan in tblOnLoan.
i have not yet been able to work out how to reduce or increase the QtyOnHand as tools are loaned or returned.
Can anyone please help?

Hi folks
I have what I reckon is a complex problem that I need to solve for my warehouse.
We hold replacement parts for the machines we sell. Some parts can be subsititued for others, so where we possible we use these parts to simplify our warehousing. Every day we get a file with demand for each part in and we look to see where we could move this demand to for those parts with a common alternative. When we find one we remove the demand from that part in the database and add it to the demand for the common part.
In operational terms we upload the demand file (.xls) to a table of the following structure
Date_added - Date
Part_number - Text
QTY - number
Thus the table holds daily demand by part. What I would like to do is use a update query to:
a) Identify the parts that have common parts to which they can be moved.
b) Add that demand to that of the common part today.
c) remove it from the original part (set to zero).
Idenitfying the parts and restricting to todays date is not a problem, however the additions and deletions are.
Any suggestions?
Thanks in advance!!

I'm making a very basic sales system for my school project and I'm currently working on the stock management part, as I said it's very basic.
My task -When the user receives a stock delivery they need to update the stock numbers. the value they need to update is the StockNumber value in the Products table. to so this I want to make a form that displays all the product names in a table with a textbox or cell next to it in which the user can enter the amount of that item that has been delivered. And at the bottom of the form there is a button which will add all these new values to the existing values.
1. There is no set number of products, the user is able to add new ones, this is preventing me from just making a separate textbox for each existing product
2. I have attached a jpeg I made in paint to illustrate how I want to the form to work as well as my system as it currently stands, there are a few unused forms and queries.
