Split Database. Update Linked Tables If Back End Moved.
Dec 7, 2007
Hi.
I'm about to move to a back end / front end system, from a single database file. Before I do so, I want to make sure I have all bases covered so to speak.
My back end file will reside on a server. I am aware that path names are sometimes changed by network administrators without warning.
From tests, I notice that, if the path to the back end can't be found, one cannot open the front end database file at all (Access 2003).
My question is: if my back end file gets moved, or the path changed, how can I get into my front end file to update the linked tables.
Many thanks in advance.
Mat.

I have built an Access 2010 split database on my computer and it functions as built. My next step was to copy it to the server at work and test it. I discovered the tables had to be re-linked and so did that. As I have read in the Access World Forums in order to function as a multi-user database a copy of the front end must be placed on the individual workstation with the back end residing on the server, however the hyperlinks in the back end will not function when the copy on the workstation is run. I simply get an unable to open "filename" error pop-up. I can run the server copy and everything functions as built. I know that the hyperlinks require all the files to be in the same folder (relative vs. absolute), but if the back end contains all the hyperlinks why does the location of the front end seem to affect the operation of the back end?

I have done the mistake of not keeping a backup, what I did is split my database file access and then created my mde file, I need to change some data on my tables, but I get the msg that I cant edit a linked table, is there a way that I could put things back the way it was, also this path that was created is it possible to change for future purposes (I might have to move the dir into a different path)
Thanks.

Hi, I am not sure where to put this thread hopefully someone here can help me.
I have spent a good deal of time developing a very effective access database for a client. It is split into a front end and back end and connected using the Linked Table Manager when necessary.
The front end is quite loaded with queries, reports, forms, macros etc and the back end simply has the tables.
The front end is about 15 mb and the back about 8 mb.
Current set up is a small workgroup network with about 4 -5 consecutive users at any one given time.
I am looking for some advice on how to set up or facilitate getting the backend on the internet so anyone with a front end can access it outside of the LAN.
Today I set up an account with WebDrive which can connect to and assign a drive letter on your pc to any FTP, HTTP site.
I made the connection with WebDrive and using the linked table manager successfully linked the tables on my local machine to the back end on the FTP server - and actually ran the database at a pretty good rate.
I noticed however that it was downloading the backend to my local pc and once I closed the (a) form it was uploading the data back to the server? Very slow and often threw errors.
This of course is not what I wanted. Has anyone heard of doing this? Any work arounds or setting params would be greatly appreciated.
I have been told to create the DB in ASP but I do not have any idea on how to do that whatsoever...
Any advice or insight would be awesome!
Thanks!

I have a database already split and I wanted to put a password on the back end. When I open up the front end and try to navigate through the forms it says "Not a valid password".Is there somewhere I need to go / something I need to do to link up the two now that a password has been created?

I am trying to use VBA to backup the BACK-END of a split database (so I can automatically archive selected data). If I use FileCopy I get a message that the BACK-END database has not been found.Obviously I could 'unlink' the BACK-END, copy it and 're-link' it..Is it possible to copy the BACK-END tables(not just the links) into the FRONT-END and get at them that way?

So the database I have right now is split, with the back end on our server. Everything has been going great, however there are several second time delays when loading large forms, queries, etc. I've heard that moving the back end to an sql server is the way to go for speed.All forms and queries are on front end of database. Tables are located on the back end which is sitting on the server.

I am new to using access and have customized a project management database for a friend's company. I need a way to auto relink the front end and back end databases when moved in the same folder. I am currently using Access 2013 and have already tried using the code on this site: [URL]...... Does this code not work for Access 2013 or am I adding it incorrectly.

I have a split database. I have secured the mde sufficiently but I need to secure the back end so that no one could link to tables in it. If I introduce a password to the back end is this going to require those using front end to supply the password? If not then this could be good solution.
As the database is on the network drive, is there any other way to prevent people to link to the db? Can I hide the db in the network drive? Or should I hide tables in the BE. Should these still be available to be linked?

I have split database (B/E is in the SharePoint library, F/E has users on a local PCs). Sometimes, when I update/add data (does not matter if it is via form or directly in the table) it looks OK, but when I re-open the database, the data are gone.
Problem is that I cannot catch the moment when data were not saved (sometimes data are saved, sometimes not). I can point out this: if I re-enter the missing data, primary key continues subsequently, it looks like the data have never been entered. I tried to use script
Code:
If Me.Dirty Then Me.Dirty = False
on "On Close" form event, does not work.
B/E is linked by VBA code and it looks OK (no error, Link Manager shows correct path). I suspect interrupted connetion to the SharePoint but I don't know how to check it. I implemented VBA script co keep open connection to the SP but the issue persists.

I'm a bit new to Access but have managed to build a very simple database.
I have a main table which I need to add 4 columns onto the end of, the data for which comes from 4 tables linked to it. Below is how they are linked.
Main table------> Table 1
Main table------> Table 2
Main table------> Table 3
Main table------> Table 4
All 4 relationships have a join type of 2 (Include ALL records from 'Main table' and only those records from 'Table1/2/3/4' where the joined fields are equal)
However, 3 of them pull back the correct data when I refresh the Main table, but the 4th one doesn't - which appears to be to be set up in the exact same way. It does bring back data, but it's the wrong data or in the wrong order.
For example, if the related field in the Main table is "Sarah" - It needs to bring back "Programme", but some Sarah's pull through Programme, some are blank and some are another option altogether. Table 4 has no duplicates or typos etc and I've tried deleting it, loading it in again and creating a new relationship but nothing seems to work.

I am splitting a database and have created the Back end already. When I create the front end and link to the tables on the back end... The front end does not link to all the tables in the back end. The list that comes up when creating the linkings does not show all the tables in the back end. What would cause this?

I have an Access 2007 file that is 'split' so the tables are centrally stored on the server.
How do I update one the linked tables stored in the back-end file with a table from another Access file?
If I import the 'new' table it is not 'linked' - it is embedded with the Access file I am working on.
What is the correct way of doing this without corrupting the data?

Suddenly my database started to act wierd. Look at the attached image. I can't move the window containing all the forms and tables. And I need to point out that I didn't place it there myself...
How to move it? I tried everything I could come up with, i.e. remove the toolbars, changing size of tha window and the programs window, restarting, re-saving, etc.

I've been creating a new Access application and I've run into an issue. The form I created has 2 subforms on it. The data is stored on 3 different tables related by the RMAID. The data gathered from this form needs to go into our MRP application. I have linked the necessary MRP tables to my access application. How do I get the date from the form to the tables in our MRP application? The data needs to go to 3 tables from the MRP application. Do I create an append query that's run after the user completes entering the data on the form? Thanks for any help

I have a database with a front end and back end (tables on the server) that was recently converted from Access 2003 to Access 2010.
For some reason the back end keeps hanging and I have to constantly compact and repair and there has been major data loss on a regular basis.

I have split the database I have created via the splitter-wizard and found that all tables with auto-numbers have re-set back to 1.
How do I get around this problem - I have tried running an append query but it flags up an error message. For certain functions to work in the database I need to set autonumbers at different amounts .

I have a split database. I have just created anew table in the back end and created a relationship to an existing table. All done in the backend.
I have opened up my front end and imported the back end end. But when I check the relationships in front end neither the table or link is there.

I have set up a table (A) that is linked to another table(B) in my database. This linked table (A) is then used in a number of queries. When the data in the original table (A) is updated it does update the data in the linked table (B) as it should. However, when I run the queries they do not bring up any records. It seems that they are not looking at an updated version of the linked table (A) because if I rebuild the query it finds the records as it should. Any advice on this would be very gratefully received.
