Hi!
I have one table called "TRANSACTION" with:
[id transaction] [product] [product type]
And I have a 1-many relationship:
[id product] [product]
[id product] [id product_type] [product_type]
The doubt I have is how can I make the main table called TRANSACTION, once you choose a product, display on product type the types of that specific product and not all the types of all the products.
I have attached a db so as to make it clearer.
Thanks in advance!
Luis

Hello everyone. I'm not sure should I post this question here or at SQL Forum? However, my problem is this. I have 2 Tables, Table1 has AutoNumber as primary key, my second Table2 has index key field. I have one-to-many relationship on those two fields, with enforce referential integrity, cascade update and delete
The access program works fine until I upsized to SQL server. [u]Then I was unable to perform cascade update or delete. I have check SQL table (which I have little knowledge about) and seems to be okay, the relationship exists. But at ms-access I was unable to make the cascade update and delete.
I appreciate any help …. Thanks.

I have a split database.(Access 2010).Three of the linked tables are Appointments, Appointments_OLD, Appointments_NEW.
I want to use vba to rename Appointments as Appointments_OLD (replacing the current one) and to rename Appointments_NEW as Appointments (replacing the current one)
I have used:
'replace Appointments_OLD by Appointments, replace Appointments by Appointments_NEW
DoCmd.Rename "Appointments_OLD", acTable, "Appointments"
DoCmd.CopyObject , "Appointments", acTable, , "Appointments_NEW"
Unfortunately this just made Appointments and Appointments_NEW clones of one another - changes in one automatically occur in the other.
What I actually want to do is to swap the names round in the backend database while maintaining the right links to the frontend.
Is this possible using vba in the frontend?

I have three tables.
Table 1: Group
Field 1: Group Text field ( Primary key)
Field 2: Group Description Text field
Field 3: Uidgroup( Autonumber)
Table 2: Subgroup Text field
Field 1: Group ( I want to bound this column to Table 1's Group field that is column 1) I have set bound column property to 1 and column count 1 and the Subgroup table is showing group fields as input perfectly no issues in that )
Field 2: Subgroup, Text field( Primary Key )
Field 3: uidsubg( Autonumber)
Table 3: Email
Field 1: Group ( Bound to Table1's Group ; showing values in combo box, setted bound column property to 1 and showing group field perfectly, no issue in that )
Field 2: Subgroup (I want to bound Table2's subgroup field, which is column number 2, so I wrote 2 in bound column property and row source is table subgroup ; Here is some error comes up, values from subgroup field of subgroup table not being shown up in Email Table's subgroup field as combo box. )
Field 3: Email Text field
Field 4: uideml (Autonumber ) primary key
I want to prepare a Data entry form should have all these fields from all the tables. That should work in following way, first user selects Group then User selects Sub Group and write Email and save the record.
What relationship should I set, or shall I change the table structure.

Hi,
This may be a simple question, but I'd like to reassure myself, so here goes. I have a database which is used to produce a pile of reports, and the tables are linked to a second database. I now need to update the reports, and add new data for this year. But the second database is password protected, and yep, I don't know that password. (I'm taking over this project from someone who left 3 years ago - I haven't just forgotten the password honest!)
Is it ok to import new data to the second database, and still carry on producing reports?
What if I want to change the properties in one of my linked tables? Can I delete the link, change the property, and then reapply the link?
Thanks for your advice,
Antro.

Hi, There seem to be a serious bug in Access 97, and I want to know if anyone has encountered this before.
I tried to describe the problem as best as I can, I also included a flash video to describe everything, here it is:
http://naderchehab.googlepages.com/linkedtablebug.swf (~1 MB)
My database has two tables:
- dbo_InventoryLocation which is linking to SQL Server 2000 via ODBC which contains inventory quantities for each product, and
- tblPRODUCTS_BUSINESS which is linking to another access database on the network and contains product information
(item number, title, description, and a field called "InvCategory" which describes item categories). I wrote a very simple query that links these two tables together:
SELECT tblPRODUCTS_BUSINESS.InvCategory, dbo_InventoryLocation.ItemNumber
FROM tblPRODUCTS_BUSINESS INNER JOIN dbo_InventoryLocation
ON tblPRODUCTS_BUSINESS.Item_Number = dbo_InventoryLocation.ItemNumber
GROUP BY tblPRODUCTS_BUSINESS.InvCategory, dbo_InventoryLocation.ItemNumber
ORDER BY tblPRODUCTS_BUSINESS.InvCategory;
The query really doesn't matter, it's just a test. Now here's the weird part:
when I execute this query, and I scroll down to a specific category and count the number of items in that category, I see about 50 of them.
But if I specify that category as a criteria, I see more than 200!
I also noticed that this problem does not happen when I use non-linked tables.
I hope anyone has an idea what that problem might be, and I hope there is a way around it.
Thanks,
Nader

Hi,
I have two databases in Access.
One of the database acts as backend i.e it has only tables including some Linked Tables(which are linked to some third database)
Other database is an executable in which all the tables are linked to the bakend database.
I am not able to link to the linked tables in the backed database. Is there a way of doing that?

I have a database that has a linked table within it. I need to enforce referential integrity on this relationship but it won't allow me too.
Does anyone know if this can be done?
If so, could you possibly point me in the right direction
Thanks

There has to be an easy answer to my problem, but I give up. I'm pretty much a novice trying to modify what seems to be a fairly complicated database. Here goes.
The format for all of the database tables are stored in a master database and linked to the database (user database) with all of the forms, queries, etc. I am trying to add fields to one of the tables. I added the fields in the master database, made a new linked table in the user database, and created the links in the master database. My problem seems to occur with the relationships for the user database. When I create the relationships, the check boxes to enforce referential integrity, etc are shaded and cannot be checked. I am working from a copy of the database so that I can compare to the original that works. In the original database, all three boxes (enforce referential integrity, etc) are check in the master database and in the user database only enforce referential integrity is checked. In the user database, the relationship type is "One to Many - External." It SEEMS that my problem is that I can't check the "Enforce Referential Integrity" box for my relationship. Also, I don't know how to get "One to Many-External" to appear. Mine just shows "One to Many."
The error caused by my problem is as follows:
I have a subform where a combo box is used to populate a field. The source items for the combo box appear properly, but when I try to select an item input after I modified the linked table, I get the following error "You cannot add or change a record because a related record is required in Table xx." Everything I can find indicates this is a relationship problem. Interestingly enough, if I select an item that I input prior to change the table, it is accepted and input without error.
I know this is long, but I don't know how else to explain the problem.
Thanks

We are sharing an Access 2003 database amongst two departments that contains twelve (12) tables that are SQL Server linked tables. Nine (9) of the tables work just fine for people in both departments. Three (3) of the tables cannot be opened until the user refreshes the link(s) using their ODBC DSN.
We do not understand why nine of the tables work without issue but three will not.
Has anyone ever run into this issue before? Does anyone have any ideas on how to resolve this issue?
Thanks

I have been running queries and reports with data from our company database (a third-party system based on FoxPro2.6) by linking tables into MS Access 97 for years. We have now upgraded to XP and Office 2003, and suddenly I can no longer do this but get a message "Could not find installable ISAM".
I've tried to locate the required file on the Internet but no luck so far. Can anybody help me? I am currently using an old pc with Office 97 on it to run the reports, but it's in a different office location and makes the whole job very tedious. Are there any work-arounds?
Any help much appreciated!

Dear Sir/Madam,
I am having the problem of importing a database from Excel/Msaccess 2000 to a Msaccess 2000 database from which the data was originally exported. The Database consists of two tables connected in a querry and the two tables has a unique primary key thru which the two tables are linked using a querry. While importing only two tables are listed in the importing wizard and not the querry.
So how to import the data to the two tables connected by a querry using a primary unique key.
help me the procedure.
lrnathan
thanks in advance

I am really new to Access 2010 as I normally use SQL so im sure this is a very basic question. I have a form where I have linked some sql tables to a table in access so the data gets stored in SQL. The form consists of many fields the basic fields are Policy ID, Name, Office, Month, Dept etc. At the moment users have to fill this in using comboboxes and text boxes but I want to change this so when the user puts in the Policy ID all the other fields are populated ie in the office field it would have a sql query of or something that looksup the office from the policy id that is entered:
SELECT [Office] FROM DBO.DQ
WHERE [Policy_ID]='what is entered into the Policy ID field' and so on.
Also not sure if this works but as I have now linked the tables to SQL does this mean that when a user fills in the information into the form it will then update the SQL table or is this another issue?

I recall reading somewhere (fairly recently) about a parameter or property in Access which is "On" by default and allows a form/query to identify when backend table field names or query arguments are changed and automatically looks for and "fixes" the renamed link. By leaving this switched ON, the database is slower than it could be. The db speed performance can be can be improved significantly by switching this 'feature' off. (i.e. Name of the property)

I'd like to secure my frontend by disabling access to the linked tables, queries etc. I thought converting to .accde would do this but apparently not. Is there a way that this can be achieved?
I am aware that I can disbale the ribbons etc but they can all be turned back on using the options menu.

I understand right off the bat if you're reaction is "don't duplicate data!!" -- mine would be too (don't fret, I know my normalization).
I've linked a table in my db to my Global Address Book in Outlook 2007 and, upon entering an employee number as a new record, would like to verify that the number entered is listed in the GAL and then pull in the associated name and location info.
The key is that I don't want this info to rely on the GAL going forward. For example, if an employee leaves or is no longer listed in the GAL, I don't want to lose the employee info (past data is needed for audit purposes). Note: I will be creating a report later to show if there are discrepancies between the GAL and my table, but that's another story...
So, what would be the best auto-fill options in Access 2007?

I have a question that I have a Microsoft Access database (.accdb) front-end/backend split and I want to give the database to my company client. As we have the different path for the backend/frontend linked. I want some code that will popup if the database location is not found and popup with the dialog so the user then select the backend and it would be ready and there is no need to popup each time the database open, it would run once it did not find the last linked path.
Also I have tried the code of Dev Ashish URL.... but unfortunately it would ask everytime to refresh the table links and I only want to run the process of linking tables when the database start and the linked path not found.

I have MDB database linked to SQL SERVER through VPN connection.I created links to the sql server Links are dsnless..Everything works fine but when I lost VPN connection or sql connection has been broken I can't refresh links to the tables.I receive message 3146 sql connection failed..I must close database and start again...
I tried different methods like ado,dao, and vba docmd.transferdatabase,aclink... but no success, table cant be relinked.
Only way I can relink is to change ip adress in conn.string
E.g. 192.124.0.2 (1st ip- router server ip) and after connection failed i can use 192.124.0.32 (2nd ip - server local ip) and that's it if i lost connection for the 3rd time... i must restart application.
It seems that access database keep the previous connection..how to reset or drop database connection to the sql server and refresh links to the tables with vba code without closing access database...
