Errors occur when set MySQL ODBC.
My operating system is win10 x64 and my MySQL Server version is 5.5. My Connector ODBC version is 5.3.
When I establish OBDC, the connection test is successfully, just as the following image.
However, when I click the "OK" button, there comes an error. The DSN is invalid.
I have refered some websites and tutorials, but still can not solve the problem.
Do not name your Datasource ODBC. Try Foobar, or abc, it should work. For whatever reason, the string ODBC cannot be used as DSN. This does not depend on the driver used.

I am trying to add new MYSQL system DSN with no luck. There are no errors. After adding in the details and when i click OK it completes with no error but i do not see it in the list of DSN.
MYSQL connector driver version 8.0.21 x64bit has been installed. I am able to create other DSN (sql server, access, excel etc..) just not MYSQL.
Any help would be greatly appreciated.
Thanks.
I was using '.' in the Name and that was causing issue. Turns out there are some special chars that are not supported in the DataSource Name when setting up ODBC connection. :|
I am trying to make a link between MySQL and MSSQL databases using ODBC Drivers. The reason is that our website is built using PHP and MySQL and we need to manage the database from SQL Server Manag. Studio.
I have already linked MySQL to MS ACCESS, so MySQL ODBC drivers are fully working.
When I try to link them from MICROSOFT SQL SERVER MANAGEMENT STUDIO > SERVER OBJECTS > LINKED SERVERS > NEW LINKED SERVER...
With this configuration:
I get this error:
I have tried with all these versions of MySQL OBDC Drivers:
ODBC 5.3 Unicode (32-bit) - This one is the one working with MS ACCESS
ODBC 5.3 ANSI (32-bit)
ODBC 5.3 Unicode (64-bit)
ODBC 5.3 ANSI (64-bit)
ODBC 8.0 Unicode (64-bit)
ODBC 8.0 ANSI (64-bit)
For the NEW LINKED SERVER:
I have tried writing this in "Provider string":
Driver={MySQL ODBC 5.3 ANSI Driver};
DATABASE=myDB;OPTION=134217728;PWD=myPASS;UID=myUSER;SERVER=mySERVER
ODBC:DSN=KARALIGROUP32::Table=myTABLE
I have also tried writing myTABLE in "Catalog".
For the Security tab, I have tried all four options given. (In the last option, I typed the login for MySQL DB and also for SQL Server)
For the Server Options tab, I have tried given RPC and RPC out (both in TRUE or both in FALSE)
I also have to mention that the database SQL Server is not my own one, so I don't have full credentials. This is my user's permissions from SECURITY > LOGINS.
My conclusion: I think it is about MS SQL SERVER MANAGEMENT STUDIO configuration or my permissions as the user.
Thanks for your help!
Update:
I have followed the advise given by TallTed, it didn't work as yet.
In the Security and Server Options tabs, I have left them as shown in the previous screenshots.
I have also tried all the ODBC connections shown in the screenshot.
Any other ideas? Thanks for your help!
First off -- the error you've shown has nothing to do with your SQL Server user permissions.
Next -- it's important to remember that Microsoft SQL Server isn't really an ODBC client application. It is an OLE DB and an ADO.NET client application.
Also note -- 64-bit SQL Server requires a 64-bit ODBC driver; 32-bit SQL Server requires a 32-bit ODBC driver. There are some extra gotchas with 64-bit SQL Server, as described in this article on my employer's site.
If your data is strictly 8-bit "narrow" codepages, then you do not need a Unicode driver, and will probably find it easier to work with the ANSI driver. That said, given that you have ODBC 5.3 Unicode (32-bit) working with Access, I would think you'll have success using that or ODBC 5.3 Unicode (64-bit) with SQL Server.
Now -- a possible step toward success.
In your first screenshot, Product Name must be MSDASQL. You will need no Provider String, because this string comes from your ODBC DSN.
I solved it!
I was using a client computer. I installed the driver in the server and then followed this post: https://www.mssqltips.com/sqlservertip/4570/access-mysql-data-from-sql-server-via-a-linked-server/
Thanks and I hope it would help someone!
I'm currently trying something I've never done before - I'm trying to access MySQL data in an SQL Server environment. Where I am, we have two servers (the MySQL and MSSQL servers), and each stores different types of data. Recently I've found a need to write queries that include data for both servers. One of the ways I read to do this is adding a "Linked Server" in SQL Server. But try as I might I cannot seem to get a Linked Server added.
I am working on a Windows 7 system, our SQL Server instance is 2005, and the MySQL version is 5.5.31.
What I've done so far is this:
Downloaded and installed the MySQL ODBC drivers
Created a System DSN using that driver for the MySQL database, called "Production". (I also tested the connection from the Data Sources application and it connects just fine).
Checked for the Provider in SQL Server (MSDASQL) to configure options such as "allow nested queries" and "allow 'LIKE' operator"
right click on Linked Servers in Server Objects in SQL Server > "New Linked Server"
From here, I fill out the linked server info like this:
Checked "Other data source" (not SQL Server)
Chose Provider "Microsoft OLE DB Provider for ODBC Drivers"
Product Name: "Production"
Data Source: (the name of the System DSN) Production
Then in the security tab, I chose the "Connections will be made using this security context" and provided my username and login for the MySQL server.
Then this is where I run into an error every time. I always get the following error message:
The linked server has been created but failed a connection test. Do you want to keep the linked server?
ADDITIONAL INFORMATION:
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.Express.ConnectionInfo)
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "FLUX".
OLE DB provider "MSDASQL" for linked server "FLUX" returned message "[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified". (Microsoft SQL Server, Error: 7303)

If you click that link for help, by the way, nothing shows up.
I saw other people suggested trying an older MySQL ODBC driver, adding a System Data Source for the 32bit driver as well as the 64bit driver, and restarting my machine (not the DB server) -- none of these fixed my error.
What I do not understand is why my System DSN seems to work and connect fine, but SQL Server cannot see the Data Source. Does anyone see what I'm missing, or what I might be configuring incorrectly?
EDIT
Clarified that I restarted my local machine, but not the DB server since trying to add the Linked Server.
From everything you've said, you probably have a mismatch between bitnesses of SQL Server 2005 components and the installed ODBC Driver for MySQL.
System DSNs are definitely the way to go.
You probably will need to install both the 32-bit and 64-bit ODBC driver, and configure an identical (same name and everything!) System DSN with each.
I would say you may also want/need to install this patch it was useful for getting XP and 2003 to work properly for ODBC type connections for me.

Is your Database server on the same machine on which you have Sql Server Management Studio Installed? If the SQL Server is on a remote machine then you need to install the ODBC driver on remote Machine and create the DSN there as per link
I was having the same issue but the above link solved my problem.
I am trying to connect to MySQL 5.6 on a Windows Server 2008 R2 localhost with pyodbc. I used the full installation for the MySQL instance on the localhost, including the ODBC connector. I have it connecting to a remote SQL Server instance beautifully, but for the life of me I can't get it to connect to the local MySQL instance. I am using this guide from connectionstrings.com as reference.
Here's some code:
import pyodbc
def create_mssql_conn():
return pyodbc.connect(r'Driver={SQL Server};Server=MSSQLSRV;Database=ecomm;Trusted_Connection=yes;')
def create_mysql_conn():
return pyodbc.connect(r'Provider=MSDASQL;Driver={MySQL ODBC 5.6 UNICODE Driver};Server=127.0.0.1;Database=ecomm;User=root;Password=myP#$$w0rd;Option=3;')
# conn = create_mssql_conn() # This one works
conn = create_mysql_conn() # This one breaks
cursor = conn.cursor()
cursor.execute('SELECT * FROM inventory')
while 1:
row = cursor.fetchone()
if not row:
break
print row
Here is the error:
pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')
I tried everything from adding Provider=MSDASQL; to changing ANSI to UNICODE in the connection string. Any suggestions?
I was having a similar issue. I am using windows 8, and mysql.
The way I solved the problem was by going into my
control panel>Systems and Security>Administrative Tools.>ODBC Data Sources
Either the 32 bit or 64 bit version depending on your computer.
Then you click on the System DNS file. If you do not see any MySQL driver you have to click ADD. It brings up a list, from that list select the MySQL driver.
For me it was MySQL ODBC 5.3 ANSI(they have a unicode driver also). Click finish. Once you do that then you have to change your connection line in your code to the corresponding Driver that you just filled out.
Ex:
def create_mysql_conn():
return pyodbc.connect(r'Driver={MySQL ODBC 5.3 ANSI Driver};Server=MSSQLSRV;Database=ecomm;Trusted_Connection=yes;')
This should work, or at least it solved my connection issue because I was getting all sorts of different errors with everything I tried. This was what solved the issue for me.
In Win64 there are two ODBC environments: 32 and 64 bit and you can work with Python 32 bit or Python 64 bit. Check what version of Python you use and then use proper version of odbcad32.exe (32 bit version is located in the SysWoW64 directory) to create SystemDSN. With SystemDSN you can check if you can connect to the database. Then try to connect to DB from Python code.
You can list ODBC datasources available to pyodbc via my code recipe: https://code.activestate.com/recipes/578815-printing-list-of-odbc-data-sources-with-pyodbc-mod/
Head to Administrative Tools and the ODBC Data Sources. You should click on the DNS file. Most likely you'd see Microsoft Access and excel as the only data sources available, so you need to add your SQL Server. Mine was SQL Server 2008 R2, and so far, it has worked.
For the error mentioned
"pyodbc.Error: ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)')"
I installed the 'Microsoft Access Database Engine 2010 Redistributable 64-bit' as I have 64-bit system and then added the DSN in the directory of MS Access database and it's working now.
Here is the link of the video for how to create DSN and connect to python.

I am using Windows7 and Microsoft office 2010 and mysql5. I want to connect Microsoft excel with my database mysql. I have installed all the drivers. I have created a data source as well. I am going step-by-step to connect, but at the end when i click on test connections, I receive this error message
Test connection failed because of error in intializing provider unspecified error.
You probably are not using the right ODBC driver.
Please check if you downloaded the one that matches your MySQL database. (not only version number, but especially if it is a 32-bit server or a 64-bit server).
