SQL Injection Attacks and Some Tips on How to Prevent Them

The way you prevent SQL injection (or shell escape injection, etc.) is not passing unquoted literal strings to an interface that treats some characters as special. You need to transform string data to a safe quoted form before including it as part of a larger "command string" that will be interpreted by an SQL database, shell, external command, API that takes URI strings, etc.
