I have a split access database that's been in use for almost two years. The database resides on a computer which I access remotely via Remote Utilities, where I transfer the db to my local PC, work on it, then transfer back to the remote machine. We use EaseUS Todo Backups to create an image file every 30 minutes of the database file. I am currently in the process of doing some refactoring and have run into the following issue:
All of the relationships in the database have somehow disappeared. Here is what is strange about this:
About a week prior to discovering this issue I had taken a copy of the database and did not have this issue.
The relationships are gone whether I open it on my local machine or the remote machine.
Upon finding this, the first thing I did was try to restore a backup to see if the relationships were there -- they were not.
This is what I can't figure out -- I had copied the file, everything was OK, then a week later no relationships were found in either the current copy, nor any of the backups from before there was no issue.
I have tried the following to resolve this:
Updating Access on both machines.
Hiding all tables then adding back and showing 'all relationships' in relationships tab.
Looking for relationships in the database documenter.
Restoring old backups as mentioned.
I'm sure this could be a result of corruption -- but how could this corruption extend to the .pbd image files generated by EaseUS, that were created before the issue occurred?
Click the All Relationships button.
Repeatedly click the Hide Table button. Each click hides one table at a time. Continue clicking until the Hide Table button grays out. That will mean that you've hidden every last table.
Click the All Relationships button, again. This will make all of the tables (with their connecting lines intact) reappear in rows of four-each, with all of your tables now visible.

I am building an application that connects to a mysql database. I set up the data connections and data source (data set) and have begun working on development, going back and forth between adding tables and views to the database and adding forms and components to the application.
I have up to now used the "Configure Data Source with Wizard" wizard to refresh the dataset in the application. Sometimes it takes a couple click throughs to get it to fully load the changes, but that's not the end of the world.
Today, without me knowingly changing anything, when I click on the wizard button, the frame of the wizard opens and closes instantly.
My data is accessible, and the parts of the application already developed work just fine, but I don't know how to add new tables and views to my project. My worry is that something went screwy in one of the auto generated dbDataSet.* files.
I'm happy to provide more information if that will help.
To answer my own question for whomever comes here next:
I came across this solution:
https://stackoverflow.com/a/4749044/7640114
It links to a microsoft.com page that is no longer available, but copies the relevant information. Finding the corresponding files is not hard, but knowing what the wrong Provider is may not be so simple.
Mostly because of a lack of patience, I just went with the second option and deleted the entire folder, which may have been overkill. It worked, and I have access to the wizard again and can continue development, but it also wiped out my workspace layout which I now have to rebuild from my memory.
Win some/loose some. In the end, I suggest being more delicate and removing lines of code from DefaultView.SEView first, and then moving on to trying to delete the file and the folder if nessasary.
I'm facing a strange issue in MS Access (2016). When I split my database into a frontend and a backend, and encrypt the backend, my frontend fails to open.
As I open my frontend after splitting the database and encrypting the backend, I should see linked tables, which should not open until I relink them by entering the encryption password. Instead, I'm always taken to Access's 'file open' menu (Image), as if the frontend never existed! As soon as I decrypt the backend, the frontend starts working normally, displaying the linked tables.
I tried splitting another database downloaded off the internet, and the issue did not occur. So I've singled the issue down to my database file. But I don't have a development background, so I have no idea how to fix it, or what could be going wrong.
There is some VBA code in the database, which is mostly copied off the internet. I tried searching for a similar issue, but with no luck :(.
Please help!
The database files (FE, BE and unsplit) can be downloaded here.
I just fiddled around and I think I found the answer to solve this issue.
If you have used the code to block the bypass shift key and mouse click to get access to your backend database then the following steps will work for you to fix this issue.
Go to your unsplit database and and go to table view. Then click on All Access Objects Section above the tables and click on option NAVIGATION OPTIONS then tick the boxes "Show hidden objevts " and "Show System Objects"
Now go back to your table list and try to find your hidden table that holds the code to block shift bypass key, in my case my table is cold "UsysRibbons" and then you have to delete it.
Then split your database and you will be able to open your front end database even if your back end database is relocated to other folder.
But if you still want to retain block shift bypass key functionality you have to go to your unsplit database copy this "UsysRibbons" table that holds the code to block shift bypass code and paste it to only to your split back end database don't link it to your split front end, and then everything will work as usual.
If this is not the issue why you can't enter your front end when back end is relocated to other folder then you have to look at all of those hidden system tables try to delete them one by one to figure out which table is the parasite table that causes problem.
Good luck to everyone in the future who encounters the same issue.
Thanks
I am attempting to move all my vb scripts that refresh my Access Tables and Queries to our new server which I log into remotely. I have done without problem with most of my scripts however there are a few that will now work and the thing they all have in common is they have linked tables from other Access databases in them. I run a script to refresh the that table and it works fine so it shouldn't be an user access problem. I haven't been able to find anything online about it, it's very strange. The linked table is in a database that is on a shared drive but again I refresh database tables from that shared drive all of the time without issue unless there's linked table involved. Help!
So right after I posted this I figured it out, hours of my time spent and it ended up being the most irritating thing. I had mapped the drives under the mapped letters in the databases instead of the actual address on the server.
Ok, I've working with my database, and I've got 2 tables and I'm trying to create a foreign link between the two. Apparently this means I need a button called Relation View that is only visible after you set both tables to InnoDB under Operations, which I have done. But Relation View failed to show up, either at the top under the "Structure" tab, or at the bottom next to the "Print" icon where it's supposed to be. So I went here (http://www.w3expert.com/2008/03/how-to-enable-view-feature-in.html) and followed the directions to install the phpmyadmin database, which should have enabled the Relation View, but it didn't. So I'm lost. Am i missing something? Is there another way to get this to work?
To be clear, I'm working through phpMyAdmin through my MAMP server.
Edit - I've also followed the instructions on this website (http://newvibes.com/blog/enabling-relation-view-in-phpmyadmin-mamp/) and edited the server configurations in the mentioned file.
So to recap -
I've created the phpmyadmin database as per the instructions in the 1st link. Then I changed the configurations of the file mention in the 2nd link. Then I closed my phpMyAdmin and restarted my MAMP server. Reopened everything, and I still can't access my Relation View.
2nd Edit - I've been messing with phpMyAdmin, and I've noticed that "Relation View" actually pops up under the database that I imported. But it doesn't show up under any of the other databases. Am I supposed to create my databases in/under the database I imported? If so, how do I do that . . .?
Are you using MyISAM storage engine? phpMyAdmin only shows relational view with InnoDB.
Click on a table, go to Operations at the top and change Storage Engine to InnoDB. I think you can only do this one table at a time
InnoDSB has a lot of overheads for larger databases (so I understand) but should be fine for small/medium stuff.
I just deleted two days of work because I though I had a backup, but I didn't. Now I need to create the database from scratch and I just wonder, isn't there a built-in backup system, just in case of someone being stupid? It's running on localhost and I haven't exported it out before.
If you've had binary logging enabled, then you might be lucky enough to use it to restore your database.
Note: If you ask me 'how do I know if I had binary logging enabled?' this pretty much means you didn't, because it's disabled by default.
There are several options. They're covered in detail at http://dev.mysql.com/doc/refman/5.1/en/backup-and-recovery.html
If you are developing some kind of app, I'd also recommend to store your DB structure in your version control system together with your source code.
No.
Computers will do anything you command them to - but it is your responsibility to know what you're doing.
In this way, "if you wanted backups, you would have made them" - power-user tools (such as databases) are optimized for performance, not for being user-proof.
Install the MySQL Workbench:-
On left side panel (i.e. under the Administration section), you will find the option to "Data Import/Restore".
On click, you will land on the Data Import. Select the option "Import from Dump Project Folder" and then select the file based on TimeStamp of that duration when the database was deleted.
Click on "Load Folder Content"
Select database object to import, check whether the deleted database is visible or not.
If visible then select all the tables and click on start import button.
If not visible then start with step 2 again and one by one select all the dump files.
At least I was able to recover all my database which accidentally got deleted during the database restore (i.e. initialization process).
This has saved my weeks of effort.
