Export SQL code from Excel into SQL - sql

My skill level: basic user of VBA, know next to nothing about SQL (though I’ve recently learned how to execute code, etc).
I’ve created a user interface in an Excel worksheet to allow user input of report variables (dates, etc). These pass into a second Excel worksheet that, through the use of various Excel statements, creates the necessary SQL code. My macro then copies this worksheet and opens Microsoft SQL Server 2008 Rx via a shell command. Currently, I then manually click “connect” on the resultant Microsoft SQL Server 2008 R2 connect-to-server window (which does not need a password, just requires me to click “connect”), I create a new query, I paste the code in and then execute in SQL. So it is these latter steps (opening SQL, click “connect”, copy/paste code, execute) that I’m trying to automate via VBA.
To offer more context, once the SQL code has run, I then have a second macro that uses the Excel Data Connection wizard to bring the resultant SQL data back into my worksheet. This is working well.
I’ve researched this for several days on various boards. None seem to observe my approach of creating the code in Excel (probably because it is an inelegant approach). Or the post responses are beyond my skill level to understand. But I do fear that I’m asking a question that has been answered before (apologies in advance).
Thanks for whatever advice/time can be offered.
I’m using:
Excel/Office 2010
Microsoft SQL Server2008 R2 (is this the same as Microsoft SQL Server Management Studios? My SQL application shows both names)
Microsoft ActiveX Data Objects 6.1 Library (this is NOT currently checked off. One post I saw referenced the need for this. I have multiple prior AciveX Library versions available as well.)

What you're doing is very ingenious, but it's probably not necessary. Excel has a number of features for importing external data.
I would look at the Data tab in Excel and the From Other Sources section of the ribbon. You have at least three options: the From SQL Server, From Data Connection Wizard, and From Microsoft Query options.
All of these will set up a connection to a database server and execute SQL against it. They return data to your spreadsheet in different ways.
Where VBA will come into play again is in automating the generation and parameterization of the queries these will execute.
But I would set up something that works, with constants for your parameter values, first, so you get an idea of the possibilities, and then read and research dynamically setting your SQL with VBA.
You might also investigate PowerPivot, by the way.

Excel OBDC - SQL Query

I am trying to use Excel pull data from a large Oracle Data Warehouse via an ODBC connection. I have a query that works using the editor in Access. I've tried using Power Query and Microsoft SQL to use this query to get this data into Excel and I get errors.
Therefore:
Does SQL executed from Excel need to be in a different syntax? Shouldn't it still be Oracle?
How can I use this pre-written query to ping the data warehouse and get what I need?
Here is the SQL that I have so far. I had to change some table names...sorry if that makes it weird.
The SQL you posted uses Access-specific functions. That is NOT a valid SQL query if run directly against Oracle. If you have a bunch of linked tables in Access, that would allow this.
The ODBC datasource connection in Excel works differently. ODBC executes the query directly at the datasource. It does some validation first and supports a limited subset of SQL language supported at the destination. What's included in the subset is determined in part by the driver selected for the connection.
So what you want to do is use a tool that lets you build the query directly in an Oracle environment, like Quest Toad or Oracle SQL Developer. Once you have the query working there, it should be easier to port it to Excel.
One thing I like to do is put my query into a view on the database. Then I can just select everything from the view when creating the Excel connection.
It's also worth pointing you to the My Data Sources folder. When you first setup an ODBC connection in Excel, the connection is saved by default in Windows in a folder called "My Data Sources" located just under your user profile folder. For example: C:\Users\UserName\My Data Sources\Data Source Name.odc.
You can open these *.odc files in any text editor, and you should be able to manually edit the SQL here. Especially look for the <odc:CommandText> element. In this way you can build a simple query up front, and then improve on the SQL command in your favorite environment and easily move the updated SQL to the existing ODBC connection.

Automate export from MS Excel to MS SQL Server

Is there a way to export data from a MS Excel file into a SQL Server table automatically? Maybe this is done using a script of some kind.
If it's not possible to be completely automated, perhaps there's a way to do it using minimal user effort. (For example clicking a button or link)
There is a MS Excel spreadsheet where the data keeps having to be manually exported to SQL Server.
I've done this using Excel to Access before, but not too certain on how to do it using SQL Server (MS).
*MS Office 2013 and MS SQL Server 2012.
The other answers are ok. I just want to suggest an additional alternative.
If it is just 1 specific Excel file that is frequently updated, I would consider using VBA. For example, write some VBA code in Excel that uploads changes to the database when the spreadsheet is saved (or the user presses a button).
The problem with using a scheduled job is that Excel is basically a single user application. If someone has the spreadsheet open or is doing something in it when the scheduled job runs or moves the spreadsheet to a different folder, then the job may fail.
This way you also get the updated data in your database in something close to real time instead of waiting on a job to run. This might take more time and effort to set up though than some of the other answers.
You can use SQL Server Agent to run a scheduled job that imports data from an Excel worksheet into a SQL Server table.
The import is relatively straightforward to do using Integration Services, but if you've not used either of these before you might need to do some reading up on it.
You can do the following:
You need to create an SSIS package and then create a job to run the package.
The easiest way to create the SSIS package is with "Import and Export Data" tool of SQL Server. It has a nice step by step wizard.
You set everything it asks you from the source and the destinations. Until you get here, select the "Save SSIS Package":
Then you only have to create the job to run it :)

How do I upload an Excel sheet to a SQL table in a Lightswitch web client?

I have a lightswitch project in visual studio 2013, using vb.net. I would like the user to be able to click a button and have lightswitch find an excel file, and upload that file to a sql table according to a pre-determined column mapping.
My preference was to use the Office Integration extension for visual studio, which I got working with VS 2013 by downloading it from this link: http://www.ge.tt/71iuRQv/v/0
However, the documentation and examples for office integration seem to be very heavy on getting an excel spreadsheet into a display in the lightswitch web client, rather than into the sql data table, which is where I need it. Here are the examples I've been following:
http://blogs.msdn.com/b/bethmassi/archive/2012/07/18/new-and-improved-office-integration-pack-extension-for-lightswitch.aspx
Alternatively, I have an existing stored procedure, and I can request that the server call this stored proc by sending a web API extension from the client to the server. I have this working already for other stored procs, according to examples from Beth Masi and Paul van Bladel. (Stackoverflow won't let me post the links...)
The undesirable part of this approach is that the stored proc is old, and messy.
I've searched and searched, but have yet to find anyone approach this problem for VS 2013 with lightswitch. Any useful advice?
I've used the method detailed by Matt Sampson to store word files and it works very well. Since it just stores the raw binary it should handle Excel files just as well.
If you're creating the table in LightSwitch, use the Binary Type. If you use SQL create scripts use varbinary(MAX).
You need to create a custom Silverlight dialog box to gain access to the OpenFileDialog object. Then open the file in as a FileStream.
Finally, you need to add a handler for the closed method of the control and then show the control to the user. Most likely done in a button. This needs to be done on the main dispatcher.
The code examples are in C# but I just used one of the many available translators out on the web and copy/pasted the VB.NET code.
Another option might be to consider shelling out to the DTSEXEC run-time to execute an SSIS package to perform the upload - especially if the target Excel spreadsheets have predefined layouts and content data types.
Even simpler, you might be able to use the SQL Server BULK INSERT command to get the job done - although that would require a SQL Client connection to your database.

Writing data back to SQL from Excel sheet

I know it is possible to get data from a SQL database into an excel sheet, but i'm looking for a way to make it possible to edit the data in excel, and after editing, writing it back to the SQL database.
It appears this is not a function in excel, and google didn't come up with much usefull.
If you want to have the Excel file do all of the work (retrieve from DB; manipulate; update DB) then you could look at ActiveX Data Objects (ADO). You can get an overview at:
http://msdn.microsoft.com/en-us/library/ms680928(VS.85).aspx
You want the Import/Export wizard in SQL Management Studio. Depending on which version of SQL Server you are using, open SSMS (connect to the SQL instance you desire), right click on the database you want to import into and select Tasks.. "Import Data".
In the wizard, click Next (past the intro screen) and from the Data Source drop list select "Microsoft Excel". You specify the path and file name of the Excel spreadsheet, whether you have column headings or not.. then press Next. Just follow the wizard through, it'll set up the destination (can be SQL Server or another destination) etc.
There is help available for this process in SQL Server Books Online and more (a walkthrough) from MSDN.
If you need something deployable/more robust (or less wizard driven) then you'd need to take a look at SQL Server Integration Services (for a more "Enterprise" and security conscious approach). It's probably overkill for what you want to accomplish though.
There is a new Excel plug-in named "MySQL for Excel" : http://www.mysql.com/why-mysql/windows/
I just had a need to do this, and this thread has been quiet for a long time, so I thought it might be useful to supply a recent data point.
In my application roving salespeople use a copy of an Excel workbook that tracks the progress of a prospect through a loan application. The current stage of the application needs to be automatically saved back to a remote SQL database so that we can run reporting on it.
Rejected methods for updating the database from Excel:
SSIS and OpenRowSet are both methods for allowing SQL Server to pull the data from Excel, and don't work very well when the Excel workbook is sitting in an undefined location on a user's computer, and certainly not when the workbook is currently open in Excel.
ADO is now, if not actually deprecated, nevertheless looking very long in the tooth. Also, I wanted the solution to be robust in the face of the user possibly not being connected to the internet.
I also considered running a web API on the destination server. Macros in the Excel workbook connect to the web API to transfer data. However, it can sometimes be painful to allow a web API to talk to the outside world. Also, the code to make it robust in the face of temporary loss of internet connection is painful.
The adopted solution:
The solution I plan to adopt is low-tech: email. Excel emails the data to an address hosted on an Exchange server. Everyone in the company has Outlook installed, so the emails are sent by programmatically adding them to the Outlook Outbox. Outlook nicely handles the case when the user is offline. At the server end, a custom C# executable, fired up at regular intervals by the Task Scheduler, polls the inbox and processes the emails.
You could use try these add-ins :
www.QueryCell.com (I created this one)
www.SQLDrill.com
www.Excel-DB.net
You can use the OPENROWSET function to manipulate Excel data from a T-SQL script. Example usage would be:
UPDATE OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;DATABASE=c:\MySpreadsheet.xls',
'Select * from MyTable')
SET Field1='Value1' WHERE Field2 = 'Value2'

SQL behind an external data query in Excel

I have inherited an Excel spreadsheet which contains an external data query. I can edit the query, which provides a list of the columns returned, but it does provide the table that this data comes from. Is there any way to retrieve the actual SQL behind the query?
I think this may depend on the version of office you're using and the type of external data you're connecting to.
I believe if you're using Office 2003, and you're seeing columns like you say, there may be a SQL icon in the toolbar.
Click that to view the SQL used to return the data.
If you're using Office 2007, Go to the Data tab, click connections, then properties, then the definition tab, and change the command text.
However I believe you're using the first method.
This is from what I can remember, so I hope it's correct.
It could also be somewhat obsfuscated by using an ODBC link or something. Another way to get it is to run SQL Profiler on the SQL Server to see the exact SQL being executed. Of course, this won't help you edit it but you'll know what it is doing.
