Cannot remotely connect to database

Question

Im receiving a MySqlException was unhandled on a line: conn.Open();

        MySqlConnection conn = new MySqlConnection("host=fdb5.freehostingeu.com;user=1477630_one;password=******;database=1477630_one;");
        MySqlCommand cmd = new MySqlCommand("SELECT * FROM users WHERE name = '"+name+"'AND surname = '"+ surname +"';");
        cmd.Connection = conn;

        conn.Open();

I think the format of my connection string is wrong. and I've tried altering the values to see whether it's the problem but I'm still unable to connect.

what am I doing wrong?

Answer 1

ConnectionStrings.com shows this as the correct standard format:

Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;

Adjusting yours accordingly:

Server=fdb5.freehostingeu.com;Uid=1477630_one;Pwd=******;database=1477630_one;

See this other answer if you need to allow remote connections to MySQL.

Answer 2

According to their live support, they do not offer Remote Connection to MySQL on the free packages.

Answer 3

Shared web hosts almost never allow remote access to shared resources such as MySQL. What you will need to do is install a copy of MySQL in your local environment to do you development and testing. Then push your schema out through whatever tools they provide to you - these are usually web based. Then when you push your site to the shared host you the connection string you are using should work fine.

Answer 4

1) Be sure to add a reference to MySQL.Data 2) Include using MySql.Data.MySqlClient 3) Your connection string should be formatted as such:

connectionString = "SERVER=" + yourserver + ";" + "DATABASE=" + databasename + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";

4) Do a try-catch statement to catch the errors
