Vb.net Mysql: Escape String

Question

This is a realy quick question

One way to update or insert data in a database is to use prepared statements like this:

Dim cmd As New MySqlCommand("UPDATE `table` SET `field` = ?value", con)
cmd.Parameters.AddWithValue("?value", "user given value")
cmd.ExecuteNonQuery()

One would do that to prevent any chances of SQL injections. my question is if i use the mysqlHelper Class to escaps strings. It it equalivant to prepared statements? In other words is SQL injection still possible?

Here is how i use the escape character method

Dim cmd As New MySqlCommand("UPDATE `table` SET `field` =" & MySqlHelper.EscapeString("user given value"),con)
cmd.ExecuteNonQuery()

Answer 1

Yes it does but generally your better off doing it the proper way by using parameters. Using the above is just not advised.
