I have a table and I want to delete all rows with a specific card serial . There are multiple rows with the same card serial .So I wrote this code but it seems that's not working:
using (SqlConnection con = new SqlConnection(WF_AbsPres.Properties.Settings.Default.DbConnectionString))
SqlCommand command2 = new SqlCommand("DELETE FORM DevInOut where Cardserial='" + textBox5.Text + "'", con);
catch (SqlException ex)
how can assure all the rows will be deleted . Should I use procedure? How do I use procedure?
