I have an Access query that creates a data table based on user defined parameters.
The data table is linked to excel, with a shared connection to Access.
I found some VBA code to run an Access macro from Excel, that basically reruns the query and updates the Access data table.
The issue i am having, is that I can't run the Excel VBA code with the Shared Connection, as it shows an error saying it is unable to delete the data in access, and therefore cannot complete the query.
The Excel VBA only works when the shared connection (linked Table) is removed.
How can I run an Access Macro from Excel using VBA, so that the access table is updated, and then the linked shared connection table in excel is refreshed and new data is shown?
Thanks!

I have an excel work book that allows users to update multiple SQL statements at once based on data entered into cells.
Then the users copy the updated SQL and go into Tableau and paste it into the corresponding custom SQL data source in tableau and refresh it.
Is there a way to send the updated SQL code directly to the corresponding connection in Tableau?
If the table name is changing, that presents a challenge.
I have two suggestions.
Modify the twb xml.
A Tableau workbook file is simply an XML file. One part of the xml contains the connection information, including your custom SQL. VBA has some libraries for manipulating XML. You can write some custom VBA code to modify the XML that contains the custom SQL.
Use VBA to create/alter a view in teradata
Teradata allows database views. With VBA, you can connect to teradata and create/alter a view that changes based on your parameters from Excel. The key is to keep the view name constant, then Tableau will not need to be changed each time the underlying view definition is changed.
Of the two, my first choice would be the second option. It's cleaner and doesn't require distributing a new workbook file each time.
I have created a query in an Access database and exported the query result into an Excel file. Now, I want to connect that Excel file to the Access database (or to that query) so that whenever some fields are updated in database, those changes would be automatically updated in the exported Excel file (report). What would be the best way to do it?
Thanks
You can create a link between Excel and an Access table or query by going to the Data tab on Excel and clicking the "From Access" icon.
Alternatively if there is a trigger inside access that you can use to update data (or if you don't need real time updates just hourly or daily ones), you could have access programmatically re-export.
If you want to work with data in Access, but still maintain the data in Excel, you need to link to the data rather than import it. Follow these steps:
Create a blank database or open an existing file in Access.
Select File, Get External Data, Link Tables.
Select Microsoft Excel as the file type.
Select a worksheet or named range to import, and then
click Next. You can import only one worksheet or named range at a
time, and each one will become an Access table.
In the next dialog box, select or deselect the check box First Row
Contains Column Headings, depending on whether your worksheet has
headings. Then click Next.
Enter a name for the table (or accept the default name that Access
suggests), click Finish, and click OK.
Now you have an Access table that looks almost exactly like the imported table. The advantage is that it maintains a live link to the Excel worksheet and can be edited in either application.
I have got the following Problem.
I have several Excel files containing each the data of a country in one folder.
However I want to pull that all into one Excel report.
As the content of the source files change dayly, I guess the best way to do that is to do a import via an SQL Statement using Union All.
However the problem is that MSQuery only allows me to Access one file at a time. Is there a Workaround for that problem?
Maybe create a data model and use DAX?
This sounds like a job for Power Query, a free add-in from Microsoft for Excel 2010 and Excel 2013, and built into Excel 2016 as "Get and Transform" in the Data ribbon.
You can create individual queries to the different Excel files in the different folder, then create a query that appends all previous queries into one table, which can be loaded to the Excel data model or a worksheet table for further processing.
The queries can be refreshed with a click when the data has changed.
I have an Excel spreadsheet, with one worksheet, with one column, containing key values I want to use to lookup data in a SQL Server view.
I can import the view data just fine using ADO or ODBC, but cannot figure out how to have the "Microsoft Query" tool add both the Excel Worksheet and the SQL View in a single query, so that I can join the data. I had also hoped VLOOKUP might lookup external data, but did not find anything,
I have looked for hours and am stumped. Certainly this can be done somehow where I can use a key in an Excel file to fetch a single related SQL table row back into Excel? I'm a hard core C# developer but seem to regularly struggle with Excel...
I would import the excel data into a staging table in your SQL Server database.
Of course you can use ADO to get the excel data into SQL Server.
Then you can join the view with your staging table.
hope this helps.
I have SSIS Package which Exports Data from table to Excel file
Control Flow :-
Data Flow :-
This is My Step :-
Drop Excel Table
Create Excel Table with format as of my Select Query which i used to retrieve data from database
Insert Data from Database to Excel file
I Used Query Like Select * From Table Where --Some Condition
I retrieve 3000 rows out of 10000 rows and put that 3000 rows in my excel sheet.
But when open my excel sheet i saw scrollbar which goes till 10000th row and ends hence my excel sheet size also increses . how can i reduce my excel sheet size ? my excel sheet contains only 3000 rows then why blank cells which goes till 10000th row ?

Visual Studio 2008 with BIDS
I believe your issue is around the method in which you are using to create the file. You have two alternatives and both should fix your issue:
Solution #1:
You can create an Excel file with those predefined columns, essentially your empty output file - this would act as your 'Template File'. Your flow would then be this:
File System Task - Copy template file to output or working directory (rename if necessary)
OLEDB Source Task - Query your source for the data (3000)
Data Conversion Task
Excel Destination Task - Put data into new Excel file
Note: You already have steps 2 thru 3 complete, you just need to make sure you are connecting to the new Excel file. Also, to clarify, step 1 is outside the Control Flow Task.
This way is helpful because you always have a blank and consistently formatted Excel file to copy and work with.
Solution #2:
The other option is to use a Script Task and create the Excel file - you could also load the data into the file in this task. This requires some basic understanding of VB.NET or C#. Basically you would need to get a XLS library (like NPOI). This is more complicated, but gives you the best functionality.
I recommend you try solution #1 and see how that works for you.
Drop table SheetName doesn't delete the sheet instead it just deletes the row . If for the 1st time you have loaded 10K rows and then again executed the package by restricting the number of rows to 3K ,the excel file will still contain those 10K empty rows as it retains the sheet along with the empty spaces .
You can use script task to delete the sheet using COM obects .But for that you need to place the Excel PIA(Primary Interop Assemply) to make it visible for VSA or else create a new excel file every time the package runs
Else as suggested by Nicarus use File System Task to delete the existing file and create a new Excel file on every execution .
