While working with python3 programming, I installed Phpmyadmin on Debian 11, to verify database was being updated. Somehow, along the way, I got my non-joined tables to become the default values in my base table, Example, the series_id column became the actual series value in the series table. I had not done any join or view setup. I closed Phpmyadmin and when I reopened, it was still showing values from the other table. This database has four tables referenced by "xxxx_id" in four different columns.
Also, the changes in the columns automatically updated the related tables. And the python program used the values instead of the "xxxx_id". I can use view to simulate this, but upon close and open, it is gone 'til I reactivate the view and then it does not automatically update the other tables.
Does anyone know how this happened and how to make it happen in my other databases and tables? It would save my a lot of time and programming if I could do this for my other databases.
I have not been able to reproduce this and adding another column did not get the same effect.

I am using Power Query Editor to create a working file, using multiple tables from several sources.
After I combine these and make my working file, I am using it to make some work on columns I add later on the working file.
I have noticed that the values I enter in the working file are not bound to the main key, lets assume the first column, but they are independent values in a column.
The result is that if one table changes, for example one line is deleted or I change the sorting of the Query, my working file is wrong, since the data changed but the added columns remain as they were.
Is there a way to have the added columns to be bound with a value, as it is for example with VLOOKUP?
How can I make a file that will update from different sourcesbut stil I can work on it without the risk of misplacing the work I do.
I hope I am clear.
Thank you in advance!
This is fairly simple if each line in your table is unique (which in your example you say the first column can serve as a key). Setup your working columns on the table and then load the table into PQ (as a connection only). Then go to your original query that is combining your data and add a merge at the end where you merge against the table you just loaded into PQ and match on your key. Then expand only your working columns from the merge.
This way whenever you refresh your table, it will match lines against it's existing output in your work before updating, so data in your work columns will be maintained. However note this is only going to retain values, not any formulas you may be using in your work columns.
I have a customization package that has some new columns on several main tables and also several new tables. The new tables are in sql scripts and work fine. The new columns for existing tables are currently in sql scrips also. I did this a couple years ago and I honestly do not remember how I ended up there. I recently encountered a problem with the Carrier table in 2017R2. Apparently, there were columns added to the base table and publishing my project removed them. I removed the sql script and re-added the custom column through the DAC object and not it seems to work fine. I thought I had read somewhere that it was best to convert it to a main sql script.
I have other columns that I have added to SOOrder and SOShipment. I want to make sure I don't have this problem again so I want to confirm the correct method for customizing tables.
Hello and thanks for any help. I'm a noob with Access but my company has asked a question about possibly importing some information for certain records in Access. Basically, I work for an insurance company and they have a claims system which was built in Access about a decade ago by someone who has left the company recently. The system works and is fine for current needs. However, we were recently asked to amend a field for certain records (claims). Because there are about 200-300 records, we are looking at a possible import solution.
The problem is, I have never done this before and am worried that it might affect other records or other fields in the records. The only thing that needs to change is one field and the rest must remain unchanged.
I know the Access table name & record numbers (RecordNo - textbox in Access) and the name of the field I want to change (Reference - textbox in Access) but am unsure how this can be imported, how the excel file needs to be prepared and how to make sure no new records are added but instead existing records are amended.
For instance, can I just have 2 columns, one called "RecordNo" and the other "Reference"? Or do I need to add blank columns to account for the extra columns in the Access table? Do I need to create a named range or an excel table or simply put the columns in Excel? Is there any specific formatting that I should be using (Text or General or something else - the Reference will be a text value as it has both numbers and letters)? When importing in Access using the import wizard, do I need to choose "Append a copy of the records to the table"? How will it know which record to amend as the Access table will contain thousands of records that I don't want changed in any way?
I also have access to the "Navigation Pane" in Access where I can find tables and queries etc and not sure if the records in question can be bulk amended on the table instead?
To make matters more complicated, the Access database is on the server and needs to be accessed by multiple users at the same time so I would ideally like to test this out on a separate copy. But copying it to my own computer does not sever the connection with the copy on the server and any changes are reflected in the original copy immediately.
I tried looking online but I can't seem to find anything that will quash my worries. I can find a few articles talking about importing issues, though not what I would be interested in, but they are all for previous versions of Access and really I can barely understand the current version. We are using Excel and Access 2013.
If possible, I would rather not use VBA as the current database has a lot of it anyway and its's difficult to manage and navigate. I also have no idea about Access VBA, just excel.
Thank you

That is because you are only copying the front end. There is somewhere a separate access file that is the back end. Or it could be a different database system like MS SQL Server or MySQL. So your first task it to find where the actual data is.
Beyond that, under no circumstances import an excel file directly into an existing table. Create an excel file with the necessary fields (record identifier and new value) and import it as a new table, then create an update query to effect the changes you need.
I have a table in Excel that is populated by a live connection to an external database. The SQL used to generate this table and refresh it looks similar to this (only with more fields and such):
SELECT DISTINCT shr_pf_student_v.ID,
FROM shr_pf_student_v
What my customer wants to be able to do is add additional columns and manually add data that correlates to the ID in each row in Excel. Of course, when the ID data is refreshed, if new rows are added or deleted, the manually added data no longer correlates with the ID it was originally intended to match up with.
I've thoroughly explored the Excel Connection "External Data Properties" options and none solve this issue. I've only found this one solution here: http://www.mrexcel.com/forum/excel-questions/376984-database-query-possibilities.html but after several hours of attempted application, I can't get it to work and I'm not sure that it's possible to do this way either.
Lookup formulas won't work of course because as soon as the data is refreshed, the data looks just like the new refreshed set.
Any new viable options are welcomed. I've searched high and low but I can't help but think that this is such a valuable process that must be rather prevalent and have a solution developed for it somewhere out there?
Many thanks,
Lindsay
I have a project in Access where we are using tables that have the customers information. These tables were created by downloading as Excel from another site of ours and then uploading to the Access program.
The problem is that the information on our other site changes sometimes, and we really don't know what has changed on our existing information. When we append a new Excel download it will add customeraccountID's that are not on the table yet, but I need a way of finding out if there are any changes to the existing information.
I have tried an update query, but that makes forms that have a relationship to the customer information tables not show the detail section. From what I have researched, this is possibly due to the update query making the updated table read only.
I have taken an made a query that gives me a list of all the duplicates between the newly downloaded Excel and the existing table, but now I need some way to find if there is any changes. There are 60 columns where there could be changes.
We are not against manually updated our tables if we can find a way of finding out what has changed.
I have considered downloading the duplicates report to excel and running a formula using exact(a2:a61,b2:b61), but then I would have to copy that formula to every other row through thousands of rows. I have no preference to whether we find the changes by Excel or Access.
The best way would be to have Access replace the information when appending the new information, not just drop the duplicates. Which would mean having Access replace the existing data when appending. Is that possible or can a report be created that shows where the information differs?
