Microsoft Access supports "subdatasheets"
Is it possible to create this type of table from a SQL command? Or does one have to manually point and click to do it.
SQL commands can run scripts/manipulate data and organize it. It's a declarative language. What you're referring to is part of Access' UI features/capabilities.
Your subdatasheet link shows an Orders table with a 1:M relationship to an Order Details table. One Order record with many details about that Order.
The reference you linked shows you how to set this up; it doesn't take any SQL or even VBA to do this. This is a way to view data and it's correlated data from another table in a Datasheet view.

I have a list of tables that need to copied from one database to another. The list of tables resides in the table in a DB. I am trying to write a Standard Macro to perform this. This is what I have so far:
The macro reads the in list of tables and then reads that using the Dynamic Input. But I am unsure how to write the tables to the second DB. Please advise.
You can do this with a batch macro where each batch will bring in a different table. The Dynamic Input tool will not work because the tables are of different schemas.
The workflow will have a Control Parameter (set to the table name) and updating an Input Data tool. This will then go to an Output Tool that has the "Take File/Table Name from field" option selected.
I have an SQL Database (SQL Server 2008 r2) that I link to Tableau via a Custom SQL Query (connected to a view in SQL). Instead of adding the new fields in the SQL Database, I am creating calculated fields in Tableau. Thedata source connected to Tableau is a viewI created by joining other views (there is a pivot I join to the main table). I want to now add the parameters from tableau as new fields in SQL and remove them from Tableau since it is bogging the tool down. What do you recommend to be the best approach in this? I have never added fields to a view and curious how this can be achieved. All of the parameters work in tableau only via the custom SQL query (the view created), but would not if I created them from the main data table in SQL.. I hope this makes sense. Thank you so much for the help! Have a great day -p
its always a good practice to create all your required fields calculation in sql table which will improve your performance. and create a extract connection with your table instead of live.
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 am new to access and have mostly worked with SQL Server. I am trying to accomplish a task for our users and am not sure how to approach it.
We have a situation where the users need to manipulate some data in various access tables, then put the final results into one of several 'linked tables' that are defined in SQL Server and linked to access. The sql server tables will defined very generically with column names like 'col1', 'col2' etc to allow for different types of data to be uploaded.
What I would like to do is have some kind of macro or module that does this:
1) Lets the user select the source (access table)
2) Lets the user select destination (linked sql server) table
3) Lets the user map the columns he would like to copy from the source to the destination table. (If this is too difficult then just something that would copy the first x number of columns would work).
4) Deletes all pre-existing data from the target table
5) Copies all data from the source table to the target table.
Could someone give me an idea as to what would be the best approach or maybe even an example of some code that does something similar? Thanks in advance. We are using Microsoft Access 2010.
I am using MS Access 2010 and I already have sharepoint linked table created in the database.
I wanted to know how i can create indexes on this linked table. When i am going to design view of linked table and clicking on indexes cloumn getting message like this property can not be modified in linked table.
I am actually trying to run one query on top of linked table and its taking very time to return resutls when doing Analyze performance then getting message of creating indexes on few fields of linked table.
You can most certainly create and set the indexes from Access with a linked table to SharePoint.
The way you do this is bring up the linked table in table view (not design view). Then in the ribbon you click on the index button. Here is a screen shot:
You can also of course if you want bring up the table on the SharePoint site and also add the index that way.
Note that you can also use this layout mode to add new columns to the SharePoint tables from Access.
You can not create indexes on linked tables in MS Access. You will need to either create new indexes in sharepoint or import the data from your linked table and create an index on that.
