is it possible with InterBase to fire a select statement against an empty 
table witout getting in trouble.

if the table "X" looks like this:

id -> integer
dummy -> varchar

and if I do now a select like 

"select * from x where id='$id'";

I will get the error 

Warning: InterBase: conversion error from string ""

I have heard that other RDBMs don't run into trouble if you do this? What 
could I do? Remember $id is an empty value!
