update statement not updating data in db


This Content is from Stack Overflow. Question asked by Mohd Sameer

net Genius,

I am trying to update the data using “UPDATE” statement. I am not getting any run time error. However, no data is being updated in the database. Looks like something is missing in where clause.

            using (MySqlConnection con = new MySqlConnection(ConfigurationManager.AppSettings["RL_InventoryConnection"])) /*"*/
                if (con.State == ConnectionState.Closed)

                MySqlCommand cmd = new MySqlCommand("UPDATE vendormaster SET vendor_name = @vendor_name, vendor_contact_Name1 = @vendor_contact_Name1, vendor_contact_phone1 = @vendor_contact_phone1, vendor_contact_email1 = @vendor_contact_email1, vendor_contact_Name2 = @vendor_contact_Name2, vendor_contact_phone2 = @vendor_contact_phone2, vendor_contact_email2 = @vendor_contact_email2, vendor_pan = @vendor_pan, vendor_gst = @vendor_gst, vendor_address = @vendor_address, vendor_pincode = @vendor_pincode, vendor_city = @vendor_city, vendor_country = @vendor_country WHERE vendor_name like '%@vendor_name%'; ", con);
                cmd.Parameters.AddWithValue("@vendor_name", getvendorname);
                cmd.Parameters.AddWithValue("@vendor_contact_Name1", getcontactperson1);
                cmd.Parameters.AddWithValue("@vendor_contact_phone1", getcontactphone1);
                cmd.Parameters.AddWithValue("@vendor_contact_email1", getcontactemail1);
                cmd.Parameters.AddWithValue("@vendor_contact_Name2", getcontactperson2);
                cmd.Parameters.AddWithValue("@vendor_contact_phone2", getcontactphone2);
                cmd.Parameters.AddWithValue("@vendor_contact_email2", getpersonemail2);
                cmd.Parameters.AddWithValue("@vendor_pan", getvendorPan);
                cmd.Parameters.AddWithValue("@vendor_gst", getvendorgst);
                cmd.Parameters.AddWithValue("@vendor_address", getvendoraddress);
                cmd.Parameters.AddWithValue("@vendor_pincode", getpincode);
                cmd.Parameters.AddWithValue("@vendor_city", getcity);
                cmd.Parameters.AddWithValue("@vendor_country", getcountry);



        catch (Exception ex)
            throw ex;
