new SqlCommand("@companyName", string.format("%{0}%", companyName))); var cmd = new SqlCommand(SQL, con);
C) string SQL = "SELECT * FROM Customer Where " + "CompanyName LIKE @companyName"; var cmd = new SqlCommand(SQL,con); cmd.Parameters.AddWithValue("@companyName", string.Format("%{0}%", companyName));
D) string SQL = "SELECT" * FROM Customer @companyName; var cmd = new sqlcommand(SQL,con); cmd.Parameters.AddWithValue("companyName", string.format("where companyName LIKE '%{0}%'", companyName));
