How to form a correct MySQL connection string? [closed]
(3 answers)
Closed 8 years ago.
As I wrote in the topic, this works totally fine:
mysql_connect("server","username","password");
But this doesn't:
MySql.Data.MySqlClient.MySqlConnection connection =
new MySql.Data.MySqlClient.MySqlConnection("SERVER=server;DATABASE=database;UID=username;PASSWORD=password;");
connection.Open();
The exception is always
Unable to connect to any of the specified MySQL hosts
And no, the question is neither a duplicate, nor answered there
As per the documentation, this
"SERVER=server;DATABASE=database;UID=username;PASSWORD=password;"
should be
"SERVER=server;DATABASE=database;UID=username;PWD=password;"

I want to connect to a disant mysql database wich is located in another server using Asp.net C#.
How can i did it ?
Thanks.
You need this code:
var myConnectionString = "server=127.0.0.1;uid=root;pwd=12345;database=test;";
var conn = new MySqlConnection(myConnectionString);
conn.Open();
Also you need the public IP of the MySql server and the correct credentials (userid, password and database name).

SQL Server connection string
(1 answer)
Closed 6 years ago.
Apparently this connection string is incorrect?
connectionString="Server=mydb.com:1433/sqlExpress;Database=d;User Id=d;Password=pw;"
the first think that I see is that you have type wrong this part
Server=mydb.com:1433
use
Server=mydb.com,1433
the sql server use the comma to separate the port.
Also take a look at that answer: Setting up connection string in ASP.NET to SQL SERVER

I have a SQL Server 2008 R2 running but when I try to connect to the server via my C# connection string I receive an error. I have no clue of what the problem is!
Here is my connection string:
_msConnection = new SqlConnection("Server=ServerIpAdress;Database=DataBaseName;User Id=NetworkName\\UserName;Password=PW;");
I hope some of you guys can help me?
Have a great day you all!
Id=NetworkName\\UserName
sounds a bit strange, try
Id=username
Also if you can connect to the DB using MS VS, MS SMS or any other likely tools your app can connect passin exactly same paramenters.
Other things to check: Actual user running the app (IIS_USR maybe)
In your SMS or VS you can get the actual connection string being used and just copy past it.
