![]() However, certain standard stored procedure programming constructs have the same effect as the use of parameterized queries when implemented safely which is the norm for most stored procedure languages. Stored procedures are not always safe from SQL injection. This makes your application relatively database independent. setParameter ( "productid", userSuppliedParameter ) įor examples of parameterized queries in other languages, including Ruby, PHP, Cold Fusion, Perl, and Rust, see the Query Parameterization Cheat Sheet or this site.ĭevelopers tend to like the Prepared Statement approach because all the SQL code stays within the application. ![]() createQuery ( "from Inventory where productID=:productid" ) safeHQLQuery. createQuery ( "from Inventory where productID='" + userSuppliedParameter + "'" ) //Here is a safe version of the same query using named parameters Query safeHQLQuery = session. First is an unsafe HQL Statement Query unsafeHQLQuery = session. The following code example uses a PreparedStatement, Java's implementation of a parameterized query, to execute the same database query. When confronted with this situation, it is best to either a) strongly validate all data or b) escape all user supplied input using an escaping routine specific to your database vendor as described below, rather than using a prepared statement. In rare circumstances, prepared statements can harm performance.
