I have a mysql database, I have to create asp.net web API that uses this API, but now I ma facing a problem connecting mySql to visual studio!
So I have installed mysql for visual studio v1.2.9, & mysql for .NET v8.0.22.
Then I moved to my Tools / Connect to Database, I selected MySQL Database, then I got this :
I know it said that there's an error in my installation is not set right, but why everything was working perfectly fine before trying this mysql thing !
Anyone has gone through such problem with mysql ?
Any help would be much appreciated.
It is quite strange and when I install these two installation packages, I can open MySQL Database without any errors.
Open VS2019-->Click Tools-->Connect to Database-->select MySQL Database:
So please try the following steps to troubleshoot the issue:
=================================
1) disable any third party extensions under Extensions-->Manage Extensions-->Installed
a) Then, close VS, delete all cache files C:\Users\xxx(current user)\AppData\Local\Microsoft\VisualStudio\16.0_xxx\ComponentModelCache
Note: 16.xxx is VS2019 and 15.xxx is VS2017.
b) Open Control Panel-->Programs--> and find the two programs-->right-click on them-->Repair
c) After that, open VS and then test whether the issue occurs.
================================
2) If the step one does not work, I think you should restore vs to the original environment. Afterwards, uninstall the two programs.
a) Open VS-->Tools-->Import and Export Settings--> click Reset all settings
b) close VS, delete the whole vs setting folders under C:\Users\xxx(current user)\AppData\Local\Microsoft\VisualStudio\16.0_xxx
c) install the two mysql programs and remember to click Complete mode to install the two programs.
d) when you finish it, try to test again.
================================
3) the third suggestion is to repair VS or update the VS if there is a new release version.

I am able to successfully get through the "Add New Data Source" steps in my C# project in Visual Studio, and get a connection to my MySQL database. However, when I then try to proceed (Note: AFTER it says my connection was successful, and I am able to select my Database name from the dropdown), I get this:
Researching this, it seems the usual suggestion is to re-download the ADO.NET Driver for MySQL (Connector/NET), which I did -- I downloaded and installed mysql-connector-net-8.0.21.msi. But I still get the same problem/error message.
Is it that I need to add one or more of the References depicted below to my project first?
If not, what am I missing to configure my project so that I can access the MySql database from my Visual Studio app?
UPDATE
This doesn't answer my question, so I won't do that, but I was able to solve my real problem, which was getting a connection to the database and inserting records into it.
I still get the same err msg I complain about above, but I guess it doesn't matter because, as I said, I successfully updated the database.
Here's how that happened:
While waiting for an answer to my question, I continued doing what I could. I found some code for inserting records using C# into MySql and added it to my code. Intellisense saw that I needed to install the MySql package:
...so I had it do just that. It automatically also added the necessary uses clause for me while it was at it.
All's well that ends swell.
To work with a MySql database you need to have a reference to the appropriate ADO driver. This driver known as MySql/Connector could be downloaded from the MySql site, or you can simply use the NuGet Package Manager right-clicking on your references node and then search for MySql.Data package.
After installing it into your project you should still add a using MySql.Data.MySqlClient; in all files when you interact with this library.
I work on Django using VS Code with MySQL database
i had to install mysqlclient to connect with my database
Try installing mysqlclient on terminal with command pip install mysqlclient on the directory you are working.
I'm learning the way ADO.NET Models works in Entity Framework with MySQL. I Generate new test model and then select "Generate Database from model"
It produce for me new file "model_name.edms.sql" - actual MySQL script for database creation.
However to execute it I have to "Connect to Server" which by default comes as SQL Server 2012. but in my case I use MySQL and not MS SQL Server. I dont have SQL12 instance, im working with MySQL
How do I change it to connect to MySQL?
P.S. I know I can use "New Query" directly on database and copy / paste content of the file and execute. also I can use MySQL Workbench and tons of other applications, however im working in VS2013 where most of the tools already integrated, I cant believe that SQL files in VS13 can be executed only trough MS SQL12
I've just ran into the same problem and that's how to solve it.
I'm using VS 2010 Ultimate but I guess it's the same in VS 2013.
First, when you connect (and execute the sql) from the toolbar you actually request to do it on the 'Transact-SQL Editor' toolbar, which means that the toolbar handles the MS databases. That's why you ALWAYS get a connection dialog to MS databases.
If MySQL package is properly installed in VS (and apparently that's the case for you) you should:
Right click any existing toolbar (or go to View->Toolbars) and select MySQL. This should add the MySql Toolbar.
Click on the first button from the left (in 'MySQL Toolbar') to either connect to an existing Data Connection or create a new connection to your MySql DB. A MySql script tab will be added.
Copy all the sql generated from the EDMX file to the 'MySql script tab'.
Run the script from the 'MySql script tab'.
That should do it.
I know there's still a little copy-paste involved but at least you don't have to leave VS.
Hope that helps

First, you have to be sure that you have downloaded MySQL for Visual Studio. This is NOT Connector/Net (though you should probably have that, too).
In VS, when you open Server Explorer, you should be able to add a database. Input your server name, user name, password, and don't forget to click the Advanced button and add in your port (usually 3306). All of this information can be obtained from your MySQL Workbench. Now you should be able to deploy your EDMX to your MySQL database using the same steps you would use for SQL Server.
Full steps from Oracle can be found at http://dev.mysql.com/doc/connector-net/en/connector-net-visual-studio-making-a-connection.html.
EDIT: Once you've performed the steps above, right-click in a blank space of your EDMX and choose SSDLToMySQL.tt in the dropdown on the DDL Generation Template. SSDLToSQL[version].tt is the default choice.
If you rename the whatever.edmx.sql file to whatever.edmx.mysql it will open in the proper tool and allow you to connect to your MySQL database server and run the script.
Perhaps at some point the generator will be updated to create the EDMX file with the ".mysql" instead of the ".sql" file extension to begin with.
How Can i get Microsoft Excel 2010 to Connect to MYSQL Server (5.6.12)
I installed MYSQL as a WAMP installation
Windows 7 Ultimate 64bit
MYSQL 5.6.12
Apache 2.4.4
PHP 5.4.16
this should be straight forward, but i've obviously missed something
Now.. When i open Excel 2010
i then go to "Data"
i then go to "From Other Sources"
i then select "From SQL Server"
I'm then presented with the Data Connection Wizard
I have the Log on Credentials (that's not an issue)
I'm Logging on with "Use the following User Name and Password"
i require the SERVER NAME
but i keep getting this error
[DBNETLIB][ConnectionOpen (Connect()).]SQL Server does not exist or access denied
I understand the concept of what needs to happen, that being, i need to specify the connection path of MYSQL to Excel
Now.. so far i have done this...
Ensured that the WAMP Server was ONLINE and the Service was STARTED
obviously the default server is localhost that does not work, but then again on my machine that only brings up the WAMP page (so that's Understandable)
i usually access MYSQL via PhpMyAdmin the URL for the Login page is
http://localhost/phpmyadmin/
i tried entering that (that doesn't work either, but then again, i understand that is only the front end)
so..
i tried typing in MYSQL , mysql , MYSQL5.6.12 , mysql/mysql5.6.12
none of that worked
the MYSQL install path is
C:\WAMP\bin\mysql\mysql5.6.12
so.. Logically if i gave that to Excel, it should find it, But it didn't
I researched the Net and everything Either says Use the Wizard , but doesn't go into detail on the Server Name, one place said to install Microsoft Connector, I have done so.. it didnt' help
I have tried the Server Name as localhost , http://localhost , 127.0.0.1 didn't work
Using MYSQL CLI i entered "status;" and used the connection name localhost via TCP/IP didn't work
i went into MYSQL buddy and i found this
You are connected to MySQL 5.6.12 with the user Martin.Kuliza#localhost.
i tried this also, didn't work
i noticed the URL on the command line title as being
C:\Windows\System32\cmd.exe - C:\wamp\bin\mysql\mysql5.6.12.bin\mysql.exe -u
i entered all this... didn't work
i entered the part Starting from C:\wamp.... Didn't work
I've tried entering wamp, WAMP, Apache, APACHE, apache
I've tried dozens of combinations
I've tried finding the config file for connector in case that had something to do with it (couldn't find it)
i've tried looking at the config.inc.php file for clues,
I'm stuck and need some help (for this seemingly simple problem)
it's just a Connection Wizard and i'm honestly gobsmacked that i actually need to ask the forum for help, but, Sadly i do
Have you done this?
http://office.microsoft.com/en-001/excel-help/connect-to-a-mysql-database-HA104019820.aspx
Before you can connect to a MySQL database, you need the MySQL
Connector on your computer. To install the MySQL Connector
(Connector/Net), go to http://go.microsoft.com/fwlink/?LinkId=278885
and download Connector/Net 6.6.5 for Microsoft Windows. The driver
bit-ness needs to match the Microsoft Power Query for Excel add-in
installation (32-bit or 64-bit).
I FOUND A SOLUTION...
Kudos to HongTAT for keeping me on the right path....
(Even though i did do all the initial stuff that you posted, before i actually posted the question, The Act of you Posting it, Got me Looking at it a little deeper...
One thing led to another and i found the solution... Thank you
i suspect some sort of incompatibility issue must have been at fault here
i noticed that Power Query 64 bit would not install on my 64bit system
instead Power Query installer provided an Error that simply stated to the effect of:
since office is 32bit you can't install 64bit Power Query
but, i did install Connector/ODBC and Connector/Net as 64bit
perhaps there was something in that configuration that didn't mesh well with each other.
Also, Aparently "bit-ness" is a confusing term that is supposed to mean ( Ensure that that bit instruction set of the of the ODBC Connector Matches the bit instruction set of Power Query in Excel)
In actual fact you don't need Power Query or Visual Studio for that matter
However i can see the benefit of power Query, at this stage
WHAT I DID...
I uninstalled all traces of Microsoft Visual Studio from Add/Remove Programs
I Uninstalled all Traces of Visual C++ Redistributable from Add/Remove Programs
I Uninstalled Power Query from Add/Remove Programs
I Uninstalled MYSQL Connector/ODBC from Add/Remove Programs
I Uninstalled MYSQL Connector/Net from Add/Remove Programs
i left the WAMP Installation and MYSQL Intact
i conducted a Windows Update
i restarted the system
i then downloaded the following and installed it
http://dev.mysql.com/downloads/file.php?id=450946
Now.. Even though this Package installation is the same thing as installing it 1 by 1
i found that by doing a "CUSTOM INSTALLATION"
and installing all products EXCEPT FOR MYSQL SERVER
i was able to connect via the connector/net to the MYSQL Database right away
LASTLY i installed Power Query for Excel (since that was the whole point to begin with)
and this time it connected right away and Worked Perfectly
the Server Name was localhost
as i suspected
and the credentials were correct as i suspected
the only thing was that i had to set it up without Encryption of password
i got a message saying something like My Version of Office did not support encryption
or something to that effect
but, i connected without encryption and it worked perfectly
PROBLEM SOLVED
I NOW DEEM THIS QUESTION TO BE RESOLVED
THANKYOU TO HongTat
Did you try googling this before you posted your question? Because if you spent at least 10 seconds searching the internet, you would have found the answer to your question.
http://office.microsoft.com/en-us/excel-help/connect-to-a-mysql-database-HA104019820.aspx
I am not sure if this is the right place to ask this question but I am facing an issue with MySQL installed failing to recognize office 2013 and install MySQL for Excel.
Basically MySQL
https://dev.mysql.com/downloads/
Has an addin for excel that allows you to automatically connect to a database and make changes. During the MySQL installation it checks for requirements, one of which is Excel 2007 or greater. And that requirement is not met for me.
I am running Office 2013 Pro Plus (64bit) and Installing MySQL (64bit)
Can someone help? Is there any other application that you recommend?
I dont want to import and export data or files manually.
I need an application that opens all the tables in separate sheets that I can manually change and automatically save to the DB.
Any advice appreciated.
Looks like this is a known bug:
For now please try the following workaround:
Launch the MySQL Installer (if already installed launch it from Start Menu > MySQL > MySQL Installer).
Try to do a Full Installation (but you do not have to actually install them).
Go to C:\Program Data\MySQL\MySQL Installer\Product Cache
See if you have there the MySQL for Excel MSI and launch it manually.
I would look these other topics on Google.
This bug is fixed as of MySQL for Excel 1.2.1. However, due to the nature of this bug, you must manually uninstall previous versions of MySQL for Excel before installing v1.2.1+.
I faced the same problem. You can download the mysql_for_excel standalone .msi file here: https://dev.mysql.com/downloads/windows/excel/
After that copy the .msi to C:\Program Data\MySQL\MySQL Installer\Product Cache
and execute it. Restart the excel. Done
Then in the Data tab you can see this
I have a same problem in Mysql 8.0.17 and the Mysql for excel not showing in the data tab, after install and uninstall several time finally found the problem in the adds-in for user of my windows. You must open the excel app by [open as administrator] Mysql for excel appeared after this.
I have done my best to install a copy of SQL Server 2008, but have discovered my "Reporting Services" installation has failed.
Furthermore, when I attempt to "repair" both the installation (and the "Shared Components" only, per a work-around I found here, will update with link if I find it) I have no had any success, as the SQL Server 2008 SP1 Patch reports that there are issues with my server's previous installation.
When I follow the procedure to complete uninstall SQL Server 2008 for a clean install (following instructions such as removing all components via the control panel "Uninstall") I also recieve errors, and when I attempt to re-run the installer I find that the instance I previously attempted to remove still exists: "MSSQL10" for example (see screen shot), and "RS" is listed as it's components, leading me to believe that the uninstall is failing because of this "RS" issue!
I have redownloaded the installer media, and tried to re-running it, and get the same issues when I choose a new name for an instances, and try "adding" features to the one I CANNOT seem uninstall! Any advice would be very helpful, my goal is to uninstall all instances of SQL Server 2008, start fresh, and apply the SP1 patch.
Thanks. I have attached log file, and screen shot. Computer information: Windows 7 Pro.

Some error messages:
TITLE: SQL Server Setup failure.

I have pictures but not enough "reputation" to post them )-8
I experienced this problem as well - someone suggests it is corrupted Perfmon counters:
I found this ( http://social.technet.microsoft.com/Forums/en-US/sqlsetupandupgrade/thread/c9cb944d-6264-4530-9e00-ee92da3e939f/ ):
================================
Got this one figured out. The performance counters were corrupted. You can see this by opening perfmon and noticing a bunch of numbers instead of the actual counters themselves.
In order to fix (or you might want to check before you install), run:
c:\windows\system32\lodctr /R
This will reload the performance counters
This worked.
