I'm not sure if this is the right place to ask this question. If not, please direct me to the right place.
We used to have an application that was created using VB and Microsoft Access. It was an application to score calls from Agents and would then run a few calculations and grade those agents based on a few algorithms.
We replicated all that Access data onto SQL but for some reason, we were just not able to connect the VB application to the SQL Database instead. The application was also outdated and we needed a change.
Can anyone suggest software/framework that can be used to create a new application with an ability to connect to a SQL database?
EDIT: We have a Microsoft Office 365 subscription. I was thinking of using PowerApps. I've never used it before. Does anyone think this could help serve my purpose?
I have extensive experience of using PowerApps to create applications connected to SQL Server (in my case Azure SQL Database), and am mostly satisfied.
There are some constraints, but not major. Please see these posts for some further information.
I would suggest PowerApps if you have Office365.

hope everyone are okay...
I need to install any Sofware for the use of SQL. I'm just a begginer and started an online course. We have a account at work called Administrator and the only account has acces to SQL Managment studio 2014. Inside there are multiple databases linked to the external objects for stock contol purposes to collect data and view data, database was created by another company not us. Id like to download an SQL Software to run simple queries. But would need to know if it would affect any other databases or servers inside our network?.. just need to set it up for my local use.
Thanks
I'm working on a database driven program in Visual Studio 2015, in C#, Windows Form Application, and I'm using SQL Server 2014 for my databases, downloaded the most recent version from the MSDN site.
I've got it working well. But if I want other users on other computers and different versions of Windows, this would require them to have SQL Server installed, correct?
Basically the app is used for storing current medications, moods, a mood quiz, symptoms, etc.. and I store all the results in SQL Server databases. They can be edited, deleted, etc through the program's GUI. Do the users need SQL Server installed to use this app?
If so, is there an alternative to keeping databases without having to have the SQL Server connections, or is there a way to do this without the users having to have SQL Server installed? I don't want remote connections to me, I want it standalone.
Does this make any sense? If not, I can explain more. I know way back in the days of Visual Basic 4 I was making, reading and writing databases without SQL. But that was 16 years ago. So I'm wondering what the easiest solution to this is. Thanks!
In other words, you want a database that you can a) distribute to end users freely and b) that will 'connect' just to the copy of the database they have stored locally.
Here are a few options ---
SQLite over ODBC is as-easy-to-use as MSSQL, the driver can be found here:
SQLite ODBC
Use ConfigurationManager.OpenExeConfiguration to read / write your app config .xml file and use it as a key / value store. I can provide examples if needed.
Dynamically create an Access database, it should work as well as MSSQL for most things, with less overhead. Here's how:
Create an Access Database
Use SQLIte DLL. Details on SO

I am not very familiar with Access database till now i was only programming to SQL Server but now it's time to do so. I am building WinForms application which will be using Access database and i have some question related to that point if you don't mind. My application will be used by multiple users and there will be one access databsae. My questions as below:
Is there any problem with accessing access database in same time by many users or only one user can be connected?
If i develop my program to use access 2016 and some of my users will have diffrent windows version and also diffrent access version
will it works?
Should i know something else? :)
If your client want to have a file based database and this is a project constraint , MS Access is the best choice. If you want a more detailed advice, please let me know how many users will perform Read/Write or Read transactions, the size of the database and if the application will run in client-server mode in a LAN/WAN, Cloud or Remote Desktop environment.
Back to your questions:
Depending on these conditions you may range from 10 to 20/25 users. Remember that you can always try with MS Access and later upgrade to a MS SQL database in a couple of hours.
If your front-end application can link to a 2016 Access database, it will do that without installing MS Access to the clients that will run your App, i.e. the vb.net compiled App will install all needed drivers. If you develop your App within MS Access 2016 (Access Form and reports, some VBA) you can run it with the free runtime version of MS Access, but this only when no older version of Access is installed on the running workstation.
Please check with your client the real reasons for a file-based database...
To answer the questions as asked:
You might run into an issue with this, as access was really designed as a personal use database. Having anything more than a small handful of users hitting against it at once will in fact cause problems, as it's not really well designed for that purpose...
This should in theory be fine, as the application itself is interfacing with the database, not the end user...
It seems like you're taking a step backwards using access for this, and SQL might very well be better suited for this purpose. This isn't me trying to just bash access either, this comes from personal experience. Going with this sort of design is likely to cause you more headaches than good.
I've been looking all over the web for a ColdFusion-based SQL administration tool for Microsoft Access and I can't find one that's simple, free and allows running SQL statements. Any suggestions?
Thanks for the recommends, guys, I'll try SQLSurfer. (MSSSME won't work for me.)
"DISCLAIMER: Using MS Access in a (web based) production environment is not recommended."
I understand that, and part of my timeline for this website is to migrate the database to MySQL on our server.
My primary interest in this is to be able to fool around with SQL commands LOCALLY so I can modify some tables. I wouldn't use this in a production environment anyway, especially not one that already has MySQL admin (Don't worry, I have plenty of backups in case I screw something up).
DISCLAIMER: Using MS Access in a (web based) production environment is not recommended.
That said, I have to admit that there are projects, customers, etc. where you can't get around having to deal with MS Access Databases the one or other way.
There is an Open Source project on RIAForge, called SQLSurfer which is a web-based ad-hoc query tool powered by ColdFusion. It is a simple way to execute SQL statements on your database (not restricted to MS Access). http://sqlsurfer.riaforge.org/ Actually there is no download link, but you can still get the code from SVN repo. http://svn.riaforge.org/sqlsurfer/
I have been working with an earlier version for a long time and I find it useful for executing prepared SQL statements. It is a very dangerous tool, especially in production, so I'd strictly recommend to include it in a password protected administration environment and deny public access.
Can RDS satisfy your needs? works with CFEclipse / CFBuilder.
Take a look at SQL Server Management Studio Express - though I've not used it with MS Access, so can't guarantee it'll work.
Hopefully someone more experienced with the two can come along and give more details.
You can easily make one your self.
On Adobe's website you can find at least 5 of those tutorials Here's one http://www.adobe.com/devnet/flex/articles/f4cf_firstapp_part1.html which uses Apache Derby, similar to MS Access.
Of course you need to think some things through, like authentication, making some field for writting SQL statement which is going to be sent as cfquery, but it should be a nice experience to make you'r own "phpMyAdmin" ;)
For MySQL there is CFMyAdmin.com. It might connect or could be adapted to tonnect to MS Access as well. I agree with Henry though, I'd set up the DSN for your access database, the RDS conection in CFBuilder and then use the query tool.
Other alternatives might be Lita (Mac based), or a FireFox add on like Sqlite Manager. They may surprise you as to what they can open.
Also, Charlie Arehart has a long list of CF based SQL Query tools. Maybe one of them could help: http://www.carehart.org/cf411/#query
Good luck
So I've created an Access Project for one of my users so he can connect to a reporting database. The .adp project connects to the DB and he can query data to his heart's content. The problem is, no queries can be saved. Whenever he opens the project, he is presented with the following error:
"This version of Microsoft Access does not support design changes with the version of Microsoft Sql Server to which your Access project is connected. See the Microsoft Office Update Web site for the latest information and downloads. Your design changes will not be saved."
Again, this is Access 2007 and Sql Server 2005. My googling efforts - which are coming on a day when I seem to be especially stupid - keep bringing up information regarding this error for Access 2002/2003 trying to connect to Sql Server 2005, which is clearly not my problem.
I'm seeing that one can connect to Sql Server with the normal Access databases (.accdb in 2007 or some such), but I'm seeing mixed information regarding whether I want to do this or not. And since I can't get a copy of Access 2007, I can't really test this (topic for another time).
Before I do down that road, I'd like to get to the bottom of this one. Anyone have any suggestions, useful links, or useful knowledge? Or an older developer who knows the answer that is no longer needed, so I can eat him and absorb his knowledge and powers?
The account being used to connect to the DB was only a db_reader. I changed it to DBO and that fixed the problem - user can now create and save queries, and sleep at night knowing that tomorrow will bring a new day with new querying possibilities.
I'm not super crazy about this though the reporting database has been set up on a separate install/server from impotant App databases. I'm not worried about the user (or anyone on his group) blowing anything up. I'd like to understand why this is, and don't (outside of the obvious - reader is read only! I didn't expect that to extend to work in Access), and will try to do so at a later time. One of the unfortunate aspects of working at a dev shop focused on internal app development is, "well, it's working, you have other things to see to".
I am not sure if I can be of help here.
But you can have a view inside Access which connects to SQL database and use that view.
Alternatively, you can go the other way. Have a DB project with SQL Server & create a linked server to MS-Access DB.
Did you try linking to the tables through an ODBC connection?
CodeSlave, I did not. The attitude from higher up is "it's working, move on". I'm not sure the boss really wanted to go down that road anyway, but it's a moot point. I should probably try granting the account dbreader and dbwriter access and see if that accomplishes the same thing, but it being dbo isn't really a huge deal. Or rather, it's not a big enough deal that The Powers That Be want me to seek an immediate change.
I was going to try linked tables until changing the SQl Server account permissions "fixed the problem" (quotes very deliberate; it feels like one of those solutions you arrive at without a proper understanding of what it worked, which vexes me).
