this is generally true but it hides some dangers. First of all, when trying to put everything in SQL, you (sooner or later) automaticly have a db vendor lock in. The second problem is that you normally cant use persistence frameworks for that, or better said, you have to use the custom SQL hooks in various persistence products, thus circumventing the products cache abilities.

A good balance of SQL usage is my advice, i try to eliminate SQL usage in my development, you cant eliminate it completely, but its a goal. To me, most Java developers are better of when not confronted with too much SQL, the products can normally generate more efficient SQL code behind the scenes. I traced and monitored too much foreign JDBC code to know that most people are not experts in that area.
