With a prepared statement, instead of sending a raw query like I've shown above to the database engine we first tell the database the structure of the query that will be submitted. To avoid SQL injection, use a prepared query that defines placeholders for the parameters of the query statement and then binds values to those parameters.
Let's change the above statement to instead send a placeholder to the database engine:. Now, injection isn't possible since no value variable or literal is being sent to the database engine. So how do we actually get the value itself to the database? Since the bound variables are sent to the database engine separate from the query they cannot be interfered with. The database engine uses the values directly at the point of execution after the statement itself has been parsed.
In this case only one value is being passed and that value has a type of string.
