Visit the MySQL download page entitled Download Connector/Net and proceed with the obvious. Note seek out the most recent download as this will age.

Use the appropriate MySQL classes.

using MySql.Data.MySqlClient;

string connString = @"server=localhost;userid=drew;password=OpenSesame;database=stackoverflow";

.

        long lRet = 0;
        using (MySqlConnection lconn = new MySqlConnection(connString))
        {
            lconn.Open();
            using (MySqlCommand cmd = new MySqlCommand())
            {
                cmd.Connection = lconn;
                cmd.CommandText = @"select count(*) as theCount from batchQMetricsToUpdate where status=1";
                lRet = (long)cmd.ExecuteScalar();
            }
        }
        return(lRet);
