Modifying Replicated Database Using Access 2010 - ms-access

We have a system that uses replication to allow folks in two different locations to work with a common database back end. The network is not high quality, and slow so I used replication to put a back end at each location and keep them synchronized. Synchronization is done through the Replication Manager and synchronizer running on a schedule. This has been working great for the past two years. The system was originally developed and used with Access 2007 but with the back end in mdb format. So now the client is up to Access 2010. The client wanted some changes to the back end, entailing some new tables and new fields added to existing tables. No problem I think. I went to the site and opened the Replica set design master using Access 2010 and added the new tables with no problem. Then I tried to add the new fields to existing tables. I could do that in design view but when I tried to save the changes I get a message 'Operation not supported for this type of object' message. I banged my head against the wall for a while thinking I was doing something wrong, then gave up working at the client facility. I did run the synchronizer before leaving and the new tables propagated properly to the other managed databases. This part is working.
After returning to my office I thought possibly this is an Access 2010 issue. I fired up a virtual machine with Access 2007 on it and a running replication system of the same database. In Access 2007 I could open the design master and add fields to existing tables with no errors and the changes would save. Is this an Access 2010 issue or is there something else going on? I'd hate to have to re-install Access 2007 on one of the client computers to make these changes. I have the same system running on my Access 2010 machine and I can duplicate the 'Operation not supported for this type of object' issue using Access 2010 in my office. Any thoughts?
Thanks in advance for your assistance.

Old thread but I have also run into the same problems. I found that using Access DDL (e.g. ALTER TABLE) in the SQL window works to modify table design in a replicated database in Access 2010. It won't allow you to modify an existing field/column but you can at least add or drop fields from existing tables. You can use DDL to modify an existing field by adding a new temporary field to your table the way you want it, copy the data from the existing field to your temporary field, then drop the existing field. Then add a second new field with the name of the field you deleted and copy the data over from the temporary field. Then delete the temporary field. More Access DDL info here

ACCESS: Move Data --> Access Database keeps wanting to split

I have an ACCESS database that I'm using to test migration to SQL Server. It has one local table; no linked tables, forms, queries, or reports. One site said to use the open the Database Tools tab, and click the Access Database icon in the Move Data group. When I do, it tells me that the database must be split. How do I let ACCESS know that the database has been split?
The move data features up to Access 2010 ALSO had a feature to move data to SQL server. However, due to SQL server always changing and having new versions that come out at "different" times then ms-access?
the feature was deprecated, and versions of Access after 2010 don't have the move to sql server anymore.
If this is just say a simple single table, then it you can use SQL server studio to import the table. (but, you lose PK settings, and indexing, and relationships (assumes you have more then one table and related tables).
If you looking to migrate a lot of data, and a lot of tables?
Then it is high recommended that you use the Sql Server Migration Assistant for Access. (SSMAA).
It is a separate download. You can find SSMAA here:
Information on this tool, and download links can be found here:
https://learn.microsoft.com/en-us/sql/ssma/access/sql-server-migration-assistant-for-access-accesstosql?view=sql-server-ver16
While the tool has a learning curve, it is well worth the efforts for any type of serious data migration from Access to SQL server.

Using SSIS to connect to Access 365 Error 0x80040E09

I have three Access database MDB files with various tables I need to upsize to SQLServer. I need to be able to update the data regularly. I am using an SSIS package in Visual Studio. I have it set to use the 32 bit version for this project. I have one of the databases running just fine. Using the same techniques on the next database I create an OleDb connection manager using the Access 16 connection and the connection tests fine, I drop down the tables drop down and it finds the table names just fine. I pick a table and hit ok and it comes back with:
Exception from HRESULT:OxC0202038
I got these databases from another source. Two of the three were set without security. Being older MDB's they have the ability to have user level security. The table in question was in the one database that had security set to admin only. The deceiving part is that the oledb connection could find the table names at all with security set so I should not be able to read them. The ambiguity of the error message was not all that helpful either. But, once I reset the user level security to allow full access things worked fine.

Access 2013 locking other users out when linked to a Sharepoint list

I have an Access 2013 database that is stored on a remote computer. I do not have it set in a back-end/front-end setup. I have a SharePoint 2010 list linked to it as a linked table. I have 2 users that need to have access to the database at all times, others may need in it at a later date. When I link the table, only 1 user can be in the database at a time. Prior to adding the linked table, all users were able to use the database simultaneously. Now, after the first person gets into the database, subsequent users get the message:
The database has been placed in a state by user 'Admin' on machine '[computername]' that prevents it from being opened or locked.
For testing purposes, I tried creating a blank database that is connecting to that same table and tried to open it from another computer. I received the same error and all that is in there are the 3 tables needed for the SharePoint list.
Is there anything I can do to be able to have multiple users in my database again? I have full control to make changes as needed to the database, but I have no access to be able to change anything server side on SharePoint.
This is because of the 2010 SharePoint caching format.
You can avoid this behavior by going to Options -> Current database -> Caching Web Service and SharePoint tables, and untick Use the cache format that's compatible with Access 2010 or later.
Note that the different cache formats come with different features. The old (XML-based) cache format supports multiple users, the new (table-based) one doesn't. The old cache format can be taken offline manually and needs to be synchronized manually if offline, the new one automatically goes offline if SharePoint is unavailable and synchronizes automatically as soon as SharePoint becomes available. The new one supports adding fields in table view, the old one doesn't.
Through VBA you can mix caching formats for different lists, but that's generally not recommended.

Access loses table relationships when

I need to update an MS Access app that connects to a SQL Server database. I copied the app and SQL database to my development computer, opened Access and linked the tables (100+ of them). I can see the data via Access, but all of the table relationships are lost, and the forms are giving me 3146 connection errors.
How do I straighten out the data so I can add features to the app (and eventually give the app to the client to reconnect with the original SQL Server)?
Complication: I haven't used Access in 15 years, so I'm a little rusty with it...
The relationships are NOW handled by SQL server. They have ZERO to do with Access, or a web site, or VB6, or some .net program that simply connects to SQL server. The .net program, the VB6 program, or the software you develop using MS Access has zero to do with how the relationships are setup with the given database system (in this case SQL server).
So that web site software, or .net program, or even MS Access does not change, or control the relationships you setup on SQL server. If this were the case, then which of the programs such as .net, web site, VB6, and MS access all using the SQL server at the SAME TIME would control relationships then??
So it is not possible or practical to have the client software control or set the relationships used by SQL server, since then it would be the client software controlling this, and every program that connects to SQL server could then be different!!! (and thus no enforced relationships would be possible as all programs would have differing ideas as to how the relationships are supposed to be!!!).
Any relationships settings you have in Access are thus ignored by SQL server, since it is now SQL server that is managing the database – not Access.
Access is just a developer’s tool like VB6, or say vb.net – those programs are free to connect to SQL server. Since many different programs are able to connect to SQL server, then the programs connecting are not the ones that control relationships – it all has to be done and set on SQL server.
Access will still allow you to use the relationships diagram. You can thus still draw out relationships in that window if you want, but you note how the options to “enforce” the relationships are now gray out – they can’t be used. So it still can be a documentation tool, or a means to make a cute diagram, but as such, it will not affect the operation of SQL server.
As for you errors? Well, before you attempt to open any form, you want to click on a linked table, and see if that works first. No use to try code, forms, reports if you not FIRST sure that the table links are active and working. ONLY until such time that you can click on, and open a linked table should you be concerned with trying to use forms, code, reports etc.
I would suggest you use the linked table manager, and re-link the tables. Now, I suppose you could delete the links, but I do NOT recommend that as a first try, since the table names will likely have a dbo prefix in front of them, and this will result in all your table names being changed, and that will break near everything in your application. So really try the refresh approach, since if you have lots of tables, then you have to re-name them all if you delete the links and re-link (so try to avoid my suggesting to delete the table links and recreating them – it will save a lot of work).
So first step:
Make sure the table links works. (don’t try code, don’t try forms, don’t try reports).
You need to ensure that a simple linked table works, and that you can simply open these linked tables. Skipping this step means everything else you attempt is folly and a waste of time.
So click on a linked table and see if you can then open + view that linked table data.
If not?
Then I would launch the linked table manager, and select all linked tables, and then force a re-fresh. (make sure you click on the box to [x] “Always prompt for new location” in the lower left corner of the linked table manager.

Sharepoint MsAccess synchronization

HI!
Does anyone have any idea how to synchronize MS Access data to SharePoint portal. I would like to link both of this together and trigger a workflow upon receiving a new data entry.
Hope you could advice on it.
Thanks!
In Access you can have so called "linked tables". You can have access linked tables with a Sharepoint installation. In Sharepoint this linked table manifests itself as a regular list, so you can have a workflow trigger on each new item created.
There is a nice tutorial here: How to Link SharePoint Server 2007 Lists with Microsoft Access 2007 and for Sharepoint 2010 and Acccess 2010 Microsoft hast written something nice: Synchronize a SharePoint 2010 list with Access 2010.
Additionally let me show you some Screenshots from Access. When you go to External Data > Export > Sharepoint List (see next screen)
When you click on that button you get the following dialog where you can select where to export your table to:
The same dialog you get when you Right click on a table, go to Export > Sharepoint List.
Now if you want to synchronize your data, you need to link that created Sharepoint list to your Access DB. So you click on External Data > Import > From Sharepoint List and you get the following dialog:
When you have a linked table it is synchronized with Sharepoint.
I think you are looking for this article.
http://office.microsoft.com/en-us/sharepoint-designer-help/add-a-database-as-a-data-source-HA010100908.aspx
Basically, you need to create a new Data Connection Library (pick from the Library list in the "Create" page). And then follow the steps depending on the connection method (i.e. Single Sign-On, custom connection string, or user id/password).
The process involves migrating your access tables to SharePoint. So if you moved or migrate a table in Access to SharePoint AND THEN choose to link the table, then it is a live connection to SharePoint. This is a bi-direction synnc of that table. So any change in Access (any update to that linked table) will see changes sent to the same table (list) in SharePoint. This is a VERY different process then trying to sync a whole file. So power-point files, or even a Access file does not work well at the FILE level, and you don't get any kind of multi-user setup.
However, if you migrate the tables to SharePoint lists, then any sql query you build in Access against that linked table will work just fine. And that includes append query, update query, or just a select for data.
And you can even work against these linked tables in off-line mode. This means that you can continue to update the tables even without network connection. When you do finally get wi-fi or some internet connection, then the data will auto-sync (both ways) and tables will update missing or changed data.
Note that you can even migrate and maintain related data, and SharePoint now supports relations and maintains those relations for you (referential integrity between tables is supported when using Access 2010 (or later) and SharePoint 2010 (or later).
VERY careful steps are required to migrate related tables. Access will migrate and send related tables of data to SharePoint (and maintain the relations for you). You simple have to ensure that your relations are of a type that SharePoint supports.
This means your PK has to be a autonumber ID type, and the foreign key has to be standard long data type. Since this setup is the vast majority of Access relationships, then these types of related tables move rather well to SharePoint. However, if you PK/FK setup is say a string, then such relationships don't work in SharePoint.
The other issue is to keep in mind that performance issues can arise when the row count exceeds 5000 rows when using Office 365 or hosted SharePoint. If your SharePoint system in on-premises then you can turn off some of these limits.
Migration of related data tables is easy, but you need to ensure you setup the relationships using the table lookup wizard in most cases. Sometimes you can use the relationship window, but in most cases, you need to re-build the relationship in a correct way BEFORE you migrate the tables to SharePoint. If your don't have related data, and just a few tables, then you don't really have to do much of anything in Access before you migrate such tables.
As noted, once migrated to SharePoint, then any sql query you execute against such linked tables will work fine. So no need to update the table local, or on SharePoint - the whole process is fully automatic and synced for you.
This video shows how to migrate related data tables to SharePoint if that is your requirement:

Edit
Given that the tags are for SharePoint 2007, then you will find that access 2010 (or later) and SharePoint 2010 (or later) is required for referential integrity to work. And pre Access 2010, you find performance of linked lists to be rather slow, and table row counts needs to be keep small. (under 10,000 rows).
