Relinking Access Tables Problem
Jun 5, 2007
I have developed a distributed database application in Access 2003 that links to local SQL Server databases in each district office. Recently I updated to Access 2007 on Vista. When I go to relink the application to a district office database I keep getting a ODBC Call Failed error. To relink I delete the old ODBC DSN and created a new one for the particular district office. Current work around involves restarting the whole computer and it only works once. Luckily I still have my XP/Office 2003 computer behind me for now but keen to find out if anyone wlse has experienced similar problems.
I have also uninstalled/reinstalled Office 2007 just in case but no luck.

I have another problem. I am having troubles relinking a front end (secured) database to a back end database and I am not familiar with security so I don't know if it is done through security. The problem is when I copy the backend to backup the front end then using the new address as a link to the frontend.
I didn't design the frontend so I am unable to enter to change the relink if it is secured.
Is there any programs or code (and where do I put it) to change the links. There should be as this is a simple problem.
Deesy.

Credit goes to FoFa for posting this code on this form.
Attached you will find code to relink tables. I manage I am doing to wrong, and need help in order for it to execute correctly. I would appreciate direction.
What I am doing:
Copying the modules over to my unsplit database.
Creating a form called ReLink.
Setting a macro (AutoExec) to open the the form.
On the form's On Open event placing the function =TestIt
Splitting the database.
Verifying by opening FE that connection exists
Moving BE and reopen FE.
All I get is unable to connect the BE message. Form continues to open.
Thanks for insight.

I am having trouble relinking tables in my Front End database to my Back End database. My BE DB is on a network share and when I try using the link table manager to navigate to the correct folder I get an error message upon entering the network share folder that says:
The Microsoft Access database engine cannot open or write to the file "etworkfolder" It is already opened exclusively by another user, or you need permission to view and write its data.
I have permission to the folder and have ensured that this folder is a trusted location path.

I'm building a database for my company who refurbish computers. I'm wanting to build in functionality for if a hard drive is damaged and it has to be replaced then for us to be able to trace (based on asset and tracking numbers) what hard drive has been removed from a PC and if it has been put into stock or destroyed and if a stock drive has been put into a PC.
Any item that is brought in whether it be a PC, laptop, server or hard drive etc is given it's own unique tracking number. Same is true for any stock we buy in for refurb purposes.
I'm thinking that this will be done by having a field for the original asset number and a field for the 'current' asset I.E. the one it's been put into.

We have a frontend/backend setup and one of the tables has almost 2 million records. I've used the SSMA tool for Access to SQLServer and upsized that table. Seems to have worked well.
Now I'm wondering if I should change the link directly on the frontend or link to the SQLServer from the backend and then update the links on the frontend?I'm mostly concerned about what happens to relationships if I rename the old table and then link to the new SQLServer table.

We have been using an Access (Access 2013) program where we link the program to dataviews created in sql server.
Recently we had to re-link the data views because a change had been made to them. When we relinked the data we noticed that the field type for the field used as the primary key changed from "Short Text" to "Long Text". The programmer who created the dataview from sql server said that nothing was done at that end that would have caused the change
I know how to prevent the problem from recurring. We are changing the sql server spec from VARCHAR(8000) to CHAR(20).

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.

I have recently split my database and added a password to the back end. I am now trying to re-link the tables as I have seen in other threads, but when I do this I am not prompted for the password I just get the message 'Not a valid password'
I must obviously be doing something wrong, can anyone help?

We have an Access 2000 backend database resides in a network server drive while users connect to the backend tables with a mde file on their computers. All users have Access 2010 and the mde file was converted from the 2000 frontend with Access 2010.
The database have been running for a few weeks but recently users have been complaining about record lost on the backend table.We have also experienced one incident of data corruption where the main table could not be opened. After Compact & Repair, the table could be opened but a few records were showing xxxxx on all the fields and we have to delete and re-enter these records.Would they relate to using 2010 mde converted from 2000 frontend when the backend is still in 2000? I am a little nervous about converting both the frontend and backend to 2010 since I have heard various issues on the new version.

I am using Access 2010.I have a table that I am using to pull my data from other tables and a query.My table is called tblMyData.One of the field names is level1. This field points to another table, and gives the user the choices for states (examples California, Texas, Maine).
Another field name is level2. This field points to another table and give the user the choice for type of customer (examples Business, Consumer)
The field name level3 points to a query. The query, qryFinalChoice matches up the choices based on level1 and level2.for example, the user can pick California for level1, business in level2 and California Widgets or Los Angeles Clothing store in level3 (plus about 20 other choices).
If the user picks Texas for level1, business in level2, business in level2 and Houston rugs, or Texas style restaurant in level3 (or about 15 other choices).
-I am recording 1 for California on level1, 2 for Texas and 3 for Maine in level1.
-I am recording 1 for business and 2 for consumer on level2.
The query qryFinalChoice has all the combinations for state, business or consumer, and lastly business name or consumer name.
-qryFinalChoice has line1 to match up the choices for level1 in my table.
-qryFinalChoice has line2 to match up the choices for level2 in my table.
-qryFinalChoice has line3 to match up the choices for level3 in my table.
I do not want any of the Texas business names appearing when the user picks California, or vice versa.
My SQL in my tblMyData tab for level3 looks like this:
Select line1 from qryFinalChoice where line1=1;
I am able to get all the line items where California is a selection.How do I change my SQL to pull all the line1 choices where I have selected from level1, and all the line2 choices where I have selected from level2 automatically based on my pulldowns?

finding some way to import my tables from excel into access 2007 with comments still inside their boxes.
one of the columns in my table is called "Order No" and each field contains a Comment as a note to go with the order.
Is there a way to keep this setting when importing the tables into access 2007?

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?

Hello, this is my first post (anywhere ever)!:eek:
While I have lots of Access programming experience over the years I have broken new ground this week and am in unchartered territory and need help please!
In the organization I am working for (as Procurement Manger), we use AMMS (by Microwest) for work order generation and inventory management, etc. I have been able to import into Access the tables of interest from this SQL-based package. The problem is that I need to share the tables (via nice front end forms/queries) with about 20-30 people in the field.
I don't know much about ODBC but the administrator of AMMS was kind enough to give me access to the AMMS database tables via ODBC and I, personally have access to read the table data but none of the other people in the field can access these tables due to security rights.
So, what I have done is I created MS Access tables for each of the 4 AMMS tables of interest and I run code that runs delete and append queries on each table. I then have a separate public db that the field people access with all the queries and forms but only links to the Master db containing the 4 Access tables derived from the ODBC tables. This works ok but there are issues:
1) if any field people are on the Public db, the code to import the ODBC table data loops and does not complete the delete/append cycle on one or more of the tables. I can only refresh the table data when nobody is connected to the db - impractical.:(
2) the ODBC tables are rather large - one is over 38,000 records and it takes several minutes to run the delete/append queries.:mad:
3) When I created the Master db it was some 83MB. After running the delete/append queries it is some 179MB and appears to increase in size every time I run the delete/append code. When I run "compact db" it stops running after a short time. Does nothing but create a new file (db1.mdb) of the same huge size as the Master.:confused:
I suspect the most graceful solution would be to give each user rights to the ODBC tables from AMMS in Access. In this case, I wouldn't have to run delete/append queries and the data would always be in relative real time subject to the refresh timer. Unfortunately, due to AMMS licensing restrictions, this is not doable.
I have tried to search the internet for guidance but no luck. This forum appears to be an excellent opportunity to get expert advice on this particular issue. I thank you for your thoughts and guidance.

I have multiple tables that are created from some software that puts them each into the access database. each table is one year of data. the software cannot put all years into one table because of memory. I want to combine these tables into one. In addition, I need to do some manipulatins: the dates come over as MM-DD-YYYY strings and I need to convert them to dates MM/DD/YYYY, and also I need to parse a string to extract the General Ledger account number. I know how to use this easily from within Excel VBA using dateserial, and Instr etc., but now sure how/if I put some code into access and have it called to do this for me automatically. Each night the most recent year is automatically updated in access, so the combination file needs to be refreshed whenever the most recent year file changes.
I currently doing all of this in excel: first initialize the NewCombinedTable, then one by one dumping each year file into an excel worksheet, doing the work needed, then appending it to the NewCombinedTable. However, I think it would work much quicker if I was able to trigger the Combination to happen in Access along with the data manipulations.
I also need to know whether DAO or ADO is best for me to use with 2010...

I have a stock control database which i have nearly completed. This has Manufacturer, which is linked to products, which is linked to Sub Product(which also has field partCode). i.e. Manufacturer1 can have 3 products, and each of these products could have 5 subsystems and partcodes. Each partcode is unique to that subsystem/product/manufacturer.
I then have a pricing spreadsheet in excel, which has many tabs. A new column has been added for each item for Manufacturer,Product,Subsystem and Partcode.
I need to import these manufacturers,products,subsystems and partcodes, but into the tables with the correct relationships, i.e. product1 and product2 are products of manufacturer1 and so cannot come under manufacturer2, and so on.
I hope this makes sense, Thanks in advance for any help you can give!

Goal
I'm trying to trying to setup a MS Access database on a shared server drive where all of the main tables are linked via ODBC into an SQL database. The SQL database is updated and maintained via purchased application. It appeared that MS Access security could be used to control the type of access each user has. Most of these users will have read only access for reporting purposes since the main application is used to update and maintain the data.
What I've done.
1) I've setup ODBC Access for each user. Not sure if this should be User, System or File DSN. They all work and I can't tell at this point that it makes a difference.
2) Created the MS Access Database, created users and assigned security.
3) Linked the needed tables.
Problem
1) When I had a user try to access a table it said "Table definitions not defined". What I then realized is that the MS Access on there machine was picking up their default security. A security Table and a shortcut (.mdb1 file) that pointed to the correct security and table definitions.
2) Now when the user gets in everything seems to come up fine but when they try to go into a table they get an error saying they don't have permissions. If I relink while they have it open, they can get into the table just fine. However, they can't delete the old tables because they have 'Read only' access. I don't really want to have to relink all the tables for each user, I might as well to go to each of their machines and set them up individually...not a good idea.
What now?
This seems like something that should be fairly easy to do..what am I missing?
