I recently split my database with BE being stored on the network drive. When I open the DB and run Linked Table Manager to refresh linked tables, I get an error message that one of the tables has incorrect or long name. Looking at the table name, it refers to one of the tables that I have deleted long time ago (before db has been split and tables linked) and never used it but for some reason Linked Table Manager still sees it somewhere.
I repeat that this table does not exist anymore in my DB as it has been deleted. Do you know what could be the cause of this?

I'm using a data flow task and 2 Ole Db sources. The 2 sources bring in data from tables on 2 different databases on the same server. The 2 tables can be mapped by ids. All of the ids from the second table (closedstops) exist in the first table (stops). I need to remove all the the closed stops by id from the first table. Afterwards I need to export the first table out of the database into a text file.
Do I need to use a merge join before deleting or do I need to use a ole db command to delete records (see attached screenshot). I have looked at many questions and answers on stackoverflow as well as tutorials and none of them quite answer my question. Any help is greatly appreciated. Thank you.
Closed stops is the driver table. Leave it be.
Instead of an OLE DB Source table for "stops" change that to a Lookup Component. You are only interested in rows that match.
And then you can use your OLE DB Command to fire off single delete statements.
My preference for performance and traceability would be to insert all the "to be deleted" ids into a table on the Stops database. When the Data Flow has completed, an Execute SQL Task would then fire up to perform the deletes in a set based operation(s).
I'm implementing my first Access Database. I've read numerous guides/manuals, and I believe I'm nearly at the finish line. The Access Database will be used by 3-4 users.
I have three tables, all of which are "live" connections to three different Excel file. These Excel files are on a shared drive, which are to be updated periodically by the different users.
I have a single query that uses each of the different tables (3).
The goal is to give the users the ability to view the output of the query. From my understanding, the best way to structure Access is to split the database. I'd like the three tables to be stored in the "Back-End" database, and the Query to be on the "Front-End" database.
The issue that I'm running into is that, when using the "Database Splitter", I'm given the error "There are no tables in this database. The back-end database will be empty". I've searched for the past couple hours, but I can't seem to find a reason for this error. I believe it is quite clear that I do indeed have tables. What am I missing? Any input/suggestions are greatly appreciated!
The "Database Splitter" can be used when you have tables and front-end things in your database. The "Splitter" would then create an additional Access database, "move" the tables to the new database and create linked tables in the old database that map the the tables in the new database. You already have linked tables, so there's nothing to split (your linked tables are not even Access tables).
I am attempting to "sync" data from a read-only ODBC MySQL server to Access 2016. I need to move the data into Access so that I can more easily manipulate and create better customized reports.
I have linked the data tables between Access and MySQL, however I cannot get the data in these tables to automatically refresh. I must go into Access and hit "Refresh All".
What I'm looking to do is update all of my open tables in Access once nightly so that each morning the data used to build these reports is new. Currently if I leave these tables all evening, when I get in the next morning I must hit "Refresh-All" for Access to go retrieve the most recent data.
Any ideas?
The data in linked tables is automatically refreshed by access when you attempt to read them. You can do that by displaying a datasheet view of the database, or by a form where the linked table is the data source. Beware, we have had problems which tables with lots of records being the source for drop down lists, having the database locked.
Access only does this properly (and at speed) if either the underlying table has a unique clustered index, or after having linked the tables you create an index in access.
If you want to create a copy that you can manipulate (such as write to) and the underlying tables are read only, then you will have to create matching unlinked tables and execute some form of copy sql and appropriate points in your application.
I was working on an Access Application that has already an access database (tables, queries etc ) and a front end. I was trying to link access existing database tables with mysql. So, what I have done so far is, I have successfully linked the access tables with mysql using ODBC. My understanding regarding linking access table with mysql db was that, by doing so, I would have the same 'old' access table linked with mysql, but I was wrong. Instead after linking I got a new table (fields same as old) that has links with mysql database.

For instance, I had an 'Actor' table in access db (before linking) and after it I have 2 tables. One is the old access 'Actor' table and other is the new linked table named 'Actor1'. So, if I do changes in my old access table, the table in mysql doesn't get change but when I do changes in my new linked table i.e 'Actor1' changes happen in mysql table too.
Here the problem is my front end form/queries are using my access table the old one, so is there any way to use new 'linked' table without changing in the front end ?
Thanks in advance.
You just need to rename your Linked MySQL table (rename the link in Access only) so that it matches perfectly the name you were using for that same table before in Access. This way you won't have to change your forms, queries, reports.
There is no magic that happens in Access between local tables and linked tables. It's still up to you to move your data, make sure the MySQL table is designed the way you want it, maintain the links, delete old Access tables, etc.
A process that I am running needs to be able to delete a table and then re-create it with new data. I've recently moved it into a different database that houses all the processes for a particular division in one place. I've been required to have all the tables from the original database set up as linked tables in the new one. Now when it is run, the process deletes the linked table reference and creates a new (un-linked) table inside the new database. I know that I can delete the table through the link, but would I then be able to re-create the table and then re-link it to the new database automatically?
There are a number of ways of linking tables, but you seem to be working purely with MS Access, so
DoCmd.TransferDatabase includes Link as one of the options.
