I have a MS Access Database which has a Linked Table called "Combined" that is from a text file. I have added a new field to the Txt File but this new field is not showing in the Access Table "Combined". I have right-clicked on the "Combined" table in Access and opened up the Linked Table Manager and refreshed the link and it is still not showing. When I go through the process of Linking the Data Source(.txt file) to a new table "Combined2" it shows the new field. I am not sure what I can do to remedy this. I have tried to just create a new linked file and overwrite the table name "Combined" with the linked file but then it makes it so my queries no longer function that were linked to the "Combined" table. Any help would be appreciated.
Drop linked table in Access and create it again. Just refreshing the link in linked tables manager is not enough in case of text files because it creates import specification, which is specific for file format.

I am doing a course on MySQL and we had to download a file to populate a database with data after we make the database, but the file is just "Export" on already made database and it has its own "CREATE TABLE IF NOT EXISTS" which means you can basically use it to create the database and populate it with data.
Here is the file https://pastebin.com/u1iWcQgx (its too big to just paste here)
What I am doing
1.Open phpmyadmin
2.Create new database cardb
3.Import the file
And here is what I get when I press "GO"
My problem is that even if I need to change something...why should I need to? I mean...nobody else got this problem and this file is auto generated so there must be no errros....I suppose it is something with the database I create.
[EDIT] I used HeidiSQL and it worked perfectly....which makes me even more confused as to what is the problem.
How can I easily set the path for the front end to connect to the backend database. Do I have to use the linked table manager every time ?
I found a tool here but it isn't very reliable. There is no simple config to set the back end path ?
When importing a table from another MS-Access database you can choose between a 'table' and a 'linked source'. If you now choose the 'linked source' and then you select the file of the other MS-Access file (where you select the table you want to link to ) you will get the table in your front-end Access as a normal table with one new property 'linked table'.
Now you can do everything on the selected data in both Access environments. The data will be synchronised as soon as you enter one record (make a change in one line and go to the next line). You do not need to visit the linked table manager any more at all.
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.
http://i.imgur.com/mfSF5hR.png [See this link showing old 'access' and new 'linked' table]
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.
I have an Excel spreedsheet with all my info saved in it. From the spreadsheet I save it as 2 CSV documents. The reason for saving it as 2 documents is because my host refuses to increase the upload size in phpmyadmin. I upload the documents into a table and use it from there. But this is not the correct way to use a database. If I import my Excel spreadsheet into MS Access there is a function that I can Split the table into multiple tables that have relations and ID's so that everything is only saved once linked very nicely. The function in Access is called 'Analyze Table' but the analyze table in phpmyadmin clearly isn't the same.
I have tried to build my own databse in excel and then export it to phpmyadmin but when trying to import data into my main table with all the relations it spits this message back to me 'Cannot add or update a child row: a foreign key constraint fails'.
What is the best way to import a large spreedsheet into phpmyadmin so it works like a proper database?
Please help as I'm at a dead end
Many Thanks
