The exception says that there is a network related problem, or that the SQL server does not allow remote access, none of those are true.
Can it be that I'm trying to connect a MySQL server, and not MS SQL?
Thanks
It is because the System.Data.SqlClient namespace is designed for Microsoft SQL Server, to connect to MySQL you will need to download and reference the MySQL .NET Connector http://dev.mysql.com/downloads/connector/net/. You will then use the System.Data.MySqlClient namespace. Hope this helps.

I want to use exist db on mysql from mvc asp.net.
I installed mysql plugin for vs and mysql connector net.
Add connection string to config.
When I start vs in server explorer I see working connection, but when in project I try to add new ado.net entity data model -> generate from database wizard don't know about mysql in general, there are defaultconnection to MS sql and only two varients for new connection:
Microsoft SQL Server
Microsoft SQL Server Database file
Other
Maybe I forgot something install?
Thanks for help.
I'm trying to use Altova DatabaseSpy to connect to my remote MySQL server as a data source. I'm getting an error though
Here are the menus I'm going through:
I'm using the same port/user/password as when I connect with Django, but it's not working. I also tried using ApexSQL and can't get that to connect either.
You need to use the ODBC driver for MySQL, not Microsoft SQL Server
I want to use MYSQL database for accesssing the data in a mvc application.
The connection string that i am using in web.config is:
Then I have prepared a model,controller,view for accessing and displaying the data.
I am using LINQ o get the data from database but getting the exception:" A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
I have also installed the MYSQL connector.
Please provide me the solution to access the data using MYSQL and LINQ in MVC application
Thanks in advance.
Deleting my previous answer...I read your question as LINQPad, no idea why.
To be short, get a third party provider, I can't speak for others, but devart's dotConnect for Oracle has worked very well for us: Here's their MySQL version.
You could use NHibernate and Linq-to-Nhibernate and then you are not database tied.
NHibernate Files
http://sourceforge.net/projects/nhibernate/files/
But this I guess is dependent on how much time you have to develop!
You can't use LINQ to SQL. You should use entity framework.
Linq to SQL is only for MS Sql.
Use EF to work with any other DB, and then you can use LINQ to EF.
Linq to SQL is obsolete

LinQ to Sql is used to Connect the MsSql to LinQ.We need third party softwares to Connect LinQ with MySql.
I Can Connect LinQ and Mysql with the help of DbLinq

I have a package that imports from a AS400 file to SQL. The package executes properly within Visual Studio, but fails when set up as a scheduled job. the error message is that my password is incorrect. I know that it is correct. I also setup a package configuration and this did not work. I have searched and tried many things. Could someone give me some assistance?
Your password is incorrect.
Seriously, you "know" that your password is correct? You know better than the code attempting to use your password? Does this seem likely to you?
Consider the possibility that you and SSIS may be referring to different passwords. Maybe the one you "know" is correct actually is, but the other one is not.
Possibly a stupid answer, but how are you connecting to the AS400? If it's using ODBC drivers, you'll need the AS400 drivers installed on both local (dev) and your SQL server box. They're notoriously picky about versions.
If memory serves me correctly, when you set up the ODBC connection using the AS400 driver software, I think you need to specify connection details as well and they get explicitly saved in the ODBC connection.
The support link above is correct. To boil it down to a simple answer. Password protect your SSIS package to save the credentials needed to connect to the AS400.
With the ODBC configuration: use a system DSN instead of user DSN, it will work!
Try to use odbc connection or try to redeploy the package on your SSIS Server.
