Dear Nilay,

I strongly recommend using exceptions (what you call "try-catch"), since
you need to do something more complicated upon failure.

You can implement exceptions using eval, die and checking the return
value of eval.  This is a rather ugly way to implement exceptions, but
commonly used.  A better way is to use the Error module.

Sidenote: Consider transactions if your DB supports them, depending on
what you are doing.
