Parameter Query

-
If we pass the value with (, ' " ! $) symbols in the control that will not be accepted through normal query.

Parameter Query use a user defined variable with an @ sign.  In Parameter Query control is written in a different syntax. Column name and variable name can not be the same. Without column_name we can not perform Parameter query. Syntax- Insert- string s= "insert into Table_name (Column_name) values (@variable_name)"; cm = new SqlCommand(s,cn); cm.Parameters.AddWithValue("variable_name", control_name); cm.ExecuteNonQuery(); Update- string q = "update Proc_table set name=@name1 where email = @email1"; cm = new SqlCommand(q, cn); cm.Parameters.AddWithValue("name1", TextBox1.Text); cm.Parameters.AddWithValue("email1", TextBox2.Text); cm.ExecuteNonQuery();
