Do Tables Have To Be Linked To Do A Multiple Table Query?

Sep 13, 2006

Please could you advise me if tables have to be linked in order to perform a query on multiple tables? For example searching for a date and matching records on more than one table at the same time.

Tables :: Multiple Parents Table Linked To Child Table - Primary Keys

May 28, 2015

I have a table for a multiple parents linked to a child table. I need to figure out a way to only allow 1 parent to be coded as primary, 1 as secondary, and then the rest as other... I thought about making Primary/Secondary/Other a primary key. But then I can only have 1 other. I would have to make a finite number of parents that could be entered and I want an infinite number.... My end goal is to have a report that only has a primary and second parent on it, but the rest of the parents still exist in the table...

*Child_ID
Parent_First_Name
*Primary/Secondary/Other

Relinking Multiple Linked Tables That Are Linked To Different Databases

Feb 2, 2012

I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...

However, recently we have moved all our databases to a new location.

K:databasedb1.mdb is now residing in O:masterdatabase
and S:datadata.mdb is now residing in O:masterdata
and so on...

I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?

so,
1. find unlinkable tables
2. search its new location under O:master
3. re-link it to the new location

Database names and tables names have not been changed. Just the location of databases.

Reports :: Query Based On Linked Tables - Report Produces Multiple Copies Of The Same Record

Jul 22, 2013

My report produces multiple copies of the same record. I know why, but don't know how to fix it.

EmployeeTable.

With a one to many relationship with TrainingTable (via employee PK as FK in trainingtable).

Training table has a one to many relationship with a table called Range.

Report is based on a query that picks up the Employee/Training/Range (range just describes the training unit).

However, If I have more than one range expressed organized a training unit, the report spits out several copies of the Employee record to display all the ranges.

Linked Tables And Multiple ODBC Connections

May 18, 2005

Hi!

I'll cut right down to it: I have an ODBC connection to a (SQL Server) test database on my development machine that is identical to the live database to which a (different) ODBC connection exists on the PC where this Access application is to be deployed. The problem is that when I deploy, there are some tables that have to be updates, because they still point to my test database. The other tables look like they use the default database for that user.

I used to be able to just copy the Access application and it would work without having to update any linked tables.

To clarify, the tables that work without a problem look like this in the Linked Table Manager:

t_mytable (DSN=odbc;)

And the problem tables have this:

t_mytable2 (DSN=odbc;DATABASE=my_test_db)

I don't seem to be able to clear that DATABASE= thing up. Can anybody tell me how this works?

If this question is overly trivial, I apologize.

How To Specify Relationships When Two Tables Are Linked Multiple Times

Nov 16, 2006

Hey all, i would appreciate some help with Access here.

I am an attorney, and i am trying to set up an access database for all of my cases.

I have one table in which i keep the names, contact information, etc of all the witnesses who i have used or will be using (especially expert or law enforcement witnesses who i will be using in multiple cases).

I also have a main table in which i have a record for each case. Because I have multiple witnesses for most of my cases, I have had to create multiple relationships between my main cases table and my witnesses table.

My question is this: How do I specify when setting up a report (or a form/query/etc) that when i ask for the witness's address i am looking for the address i made with a particular witness, specify that relationship between the two tables, as opposed to the other relationships between the same two tables.

I hope that makes sense, and i would very much appreciate if someone could give me instructions.

Thank you.

How To Create A Form That Can Update Data Linked To Multiple Tables

Jul 30, 2012

I'm using Access and Excel 2007.... I know how to import an Excel spreadsheet as a table.

I have several supplier price lists in Excel. I want to keep my vendor price lists up to date.

When one of my vendors tell me that a price has changed on a particular item, I figure that I could have a form that I could use to enter the changes.

I believe the form would look like:

Field: "Vendor" (drop down list to choose from. Name of the Supplier price lists) Required.
Field: "OEM" (Key Field found in each table) Required.
Field: "Brand" (Field found in each table) Not required.
Field: "Price" (Field found in each table) Required.

OEM would be the unique key field.

If I enter the Vendor name and then the OEM number it would show if there is already that number in the Vendor price list and I could make changes. Or I could enter new data in that vendor price list.

Tables :: Query Off Of A Junction Table - Multiple Categories

Sep 26, 2013

So I have a form that has a sub form on it (based off of a junction table), indicating which category a particular project belongs to. It can belong to multiple categories:

ProjectID
100
Category
Admin
Finance

But I want to run a query to find all of the projects that are both admin and finance. When I do that now, it comes up as two separate records in the query, which is fine... but I have to know the projects before hand to find if it's in both, because it returns heaps of records, anything that says admin or finance... and that defeats the whole purpose. I want the query to show me JUST the projects that have both of those in their subform..

Tables :: Make Calculated Field In One Table That Calculates Values From Another Table Linked By Order ID

May 13, 2015

I have what is probably a stupid question but I've been struggling with this one for a while. I have an ordering database which has an Orders table (containing Order ID, Date, Supplier etc) and an Order Line table within which I have a combo box for Product name, supplier, price, VAT rate, Line price etc. At the moment, I have the order line table as a subform within the Order form (run from the Orders table). The problem I'm having is the subtotal and total fields. At the moment these are in the Order Line table as I cannot figure out how to get these in the Orders table. In summary, can I make a calculated field in one table that calculates values from another table (linked by Order ID)?

How To Partition A Table Into Two Linked Tables

Mar 17, 2006

Hi, All,

I have so far only worked with single tables and queries but not with linked tables. Now the following problem has arisen.

We have a database all of whose fields except two are of type = Text. Two fields are type = Memo.

We have to submit this database, i.e. its main table, to an external company for automatic 'cleansing' (UK: Telephone preference service). The cleansing program converts the cleansed database into a comma-delimited text file and returns it to us as such, and we then have to convert it back into an Access table.

(That's the way our supplier works, it is not under our control, and we have to learn to cope with it.)

Now the cleansing program is being screwed up by our Memo fields, because they contain commas. So when the cleansing program sees a comma, it interprets this as the start of a new field, and the same happens when we convert the text file back into a table.

Two solutions were suggested by the cleansing company, but only the following seems suffiently automatic and therefore acceptable to us.

I NEED HELP IN IMPLEMENTING THAT SOLUTION.

-----------------------------

I want to move the two memo columns into a separate table (memo table), linked to the original table (main table). Have the ID column (unique identifier) in both tables to keep the records together. Then I send only the main table for cleansing and the commas in the memo can no longer work havoc.

I have an idea of how to create the memo table: make a copy of the main table and then delete all columns except ID and the two memo columns.

But then I have to link the two tables (I do not know how to do that); where do I start.

I must also ensure that when new records are created (now usually through a form), both tables are expanded. And I must get information from both tables into one form.

At present I do not even know where to start, except for creating the Memo table by copying it and deleting certain columns.

I have a good book (John Viescas: Running MS Access 2000), but it is huge, and the problem is urgent (it stops our tiny company from marketing). I have no time to study the whole book to find what I need in this case. A chapter or page reference would be very useful.

Or some Tutorial on the web that deals with my particular task.

Thanks for your help.

Adrian

Main Table Linked To Several Sub-tables - Help!

Sep 2, 2007

Dear All

Since last week I am working on a Database which I will use for my company. To make a long story short, I didn't find any appropiate softwares nor examples on the internet, hence, with my some knowledge in Access, I am trying to make this "to be" useful tool for my self.

Short brief on the project:
This is going to be used for a trading company to register:
- Suppliers
-- Products

- Customers
-- Inquiries
-- Orders
-- Offers

*Relations:
- Suppliers can have one or many products
- Customers can have one or many Orders / Inquiries / Offers

Problems:
(I have tried many different ways, but going nowhere)

1) The "Customers" table have 3 tables (Orders/Inquiries/Offers) linked to it - and all are based on the primary key "CustomerId". --> How can I make a form to enter these data linked?

2) Under "Orders" I want to select supplier from the Supplier table and Product from the Product table -- How?

I know this is a lot of info and probably too vague, but if someone could assist me with a few problems - then I would really really appreciate it and compensate somehow.

Looking forward for your help.

Best regards

Tables :: Copying A Table From One Linked DB To Another

Dec 3, 2013

I am looking to copy one exceptionally large table to another. I can use VBA to copy the entire Report2013.accdb to Report.accdb while compacting at the same time. This is very fast and works well. However once it's copied I need to rename the table tblReport2013 to tblReport. None of these table are in the accdb that I am running the scripts from FrontEnd.accdb. I am working very hard to keep the data tables under the 2 GB limit, which is why linking and keeping the data separate is necessary. There is the chance that Report2013 will be on the network while tblReport will be local to the user, and may or may not be a subset of the Report2013.

I have considered a number of options:
DoCmd.Rename - I can't seem to tell it a database location

I could try
docmd.copyobject - and see if it keeps the file size the same or smaller then the original.

I could just write the sql statement and copy the data that way, and compact the table afterwards. The trouble with doing the transfer that way is hitting the 2GB limit, before I can compact/compress the newly imported data.It just seems odd to have to find another solution when all I really want to to rename a table and ensure the new new is still linked as a separate table.

Putting Linked Tables Into One Table?

Sep 17, 2013

I have multiple tables that are linked to excel. I am creating a product selection tool to make it easy to find the products contained all these linked tables. They are necessary as they contain pricing data and information necessary to be kept in excel which is regularly updated.

Is there a way to create one table containing data from all these linked tables? I tried using an append query but realise that when the linked tables are updated the table containing all the data wont be?

Linked Tables Not Updating In Junction Table

Nov 20, 2004

Hi, I have the following structure:

Products 1-M ORDER DETAILS M-1 ORDERS M-1 CUSTOMERS

I have ORDER DETAILS set as a junction table so that many products can be recorded within one order. All is good apart from when i go into ORDERS and create a new order. I click the subform which links to the ORDERDETAILS. I then pick a product number(look up from products table). The problem is this: In the ORDER DETAILS I want to display the unit price of this product simply by picking the product id.

Eventually this would form the basis of an order form where I can pick Product Id and have it display unit price.

Any ideas on this one, I'm sure its quite simple!!

Thanks in advance

Tables :: Deleting And Replacing A Linked Table?

Mar 5, 2014

My table (excel spreadsheet) sits on another directory from the DB. If I delete the table on this directory and immediately replace it with a table with the same filename, format, etc (only the data has changed) will each database user have to relink the table on their desktop DB? Or will the forms/subforms/reports still maintain their relationships/functions and just display the new data?

Tables :: How To Check That Linked Table Exists

Apr 16, 2013

Background: In my Access FE, I have created a "linked table" to a file on our AS400 database. I know I can check the MSysObjects table for the linked table name, but sometimes the file actually does not exist on the AS400.

The file can be in one of three states.File exists with data.

File exists, but is empty.

File doesn't exist.

Question: What is the best way to determine the status of this linked table (file)?

Tables :: Changing Linked Table Names

Mar 3, 2015

I need to update the names of my ODBC linked tables in my Access database, how can I do this without causing issues with my queries/reports?The current linked tables are to a SQL View on a database called mcsrm_live, and called e.g. vwDamagesReportNew

The new SQL views that I need to link to are identical in structure and content and on the same SQL server but different database - forkdw and are called e.g vw_R_Damages

Is there a straightforward process to do this without affecting the queries and reports in my Access db?

Tables :: Text Field On Linked Table

Nov 12, 2014

We have a database (Access 2007) with several linked tables to an MS-SQL 2008 instance. All the text fields that I have issue with are nvarchar(255) on MS-SQL. The odd thing it will not allow a full 255 characters to be entered into the field. It will fail to save unless the number of characters is about 238 or 239 characters (not sure of the exact number of characters). It shows the field as a text and field size of 255 in Access .

Tables :: Sharepoint Linked Table Uneditable

Aug 27, 2013

I'm just starting out to learn SharePoint, which I utterly hate thus far but anyway. So I have successfully linked to the sharepoint list in my DB, but I cannot edit any values for some reason. I can edit them in sharepoint and both systems update, but when I type in ANY box in access I get "Invalid arguement" error.... also note the new record button near the record navigators is greyed out so I can't add a record either.

I noticed that my library user group has URL... set to Read while all others are set to full control... is this the cause or something else?

Tables :: SQL Creates Linked Table In Front End

Dec 28, 2014

I have a frontend and a backend database. As usual i keep the tables in the backend. Now I have some tables which need to be emptied and then refilled. I empty the table using the code

Code:
DoCmd.RunSQL "DELETE * FROM TransNMTbl;"

then I fill in the table using

Code:
DoCmd.RunSQL "INSERT INTO TransNMTbl SELECT * FROM TransTbl;"

The code runs fine. The problem is that the linked table is not used and the sql statement creates another TransNMTbl table in the front end and puts the data there. Bu I need the table to be in backend.
