Are SQL stored procedures secure?

Although SQL Server’s stored procedures help with code security by hiding the implementation of the business logic and even protecting against some kinds of SQL injection attacks – primarily those that use an operator such as AND or OR to append commands onto a valid input parameter value, simply wrapping the code into a stored procedure doesn’t mean that applications, database and SQL Server are safe from all types of SQL injection attacks.
