Database Connectivity Problem

I am currently working on my local machine in Visual Studio 2012. In my adminTools.aspx.cs page I am trying to call my database. This is the method that is causing me issues.

protected void populateJobInformation(object sender, EventArgs e)
{

SqlConnection dbConnection = new SqlConnection("server=my02.Winhost.com;database=mysql_database_database;user=user;password=password;");

dbConnection.Open(); //This line is where the error occurs
dbConnection.ChangeDatabase("mysql_database_database");

string query = "SELECT * FROM Properties WHERE Job= " + updateJobID.Text;

SqlCommand sqlCommand = new SqlCommand(query, dbConnection);
SqlDataReader records = sqlCommand.ExecuteReader();

while (records.Read())
{
jobList2.Text = "" + records["jobType"];
updateJobName.Text = "" + records["jobName"];
updateJobDesc.Text = "" + records["jobDesc"];
}
records.Close();
dbConnection.Close();
}
