package Beans;

Answer 1

I am bit doubted about your query as well, you might need to look at this

   CREATE TABLE `test1` ( contact_id INT(10),name VARCHAR(40),
   birthdate DATE,PRIMARY KEY    (contact_id));

If the update happens correctly then the value is 1, if not its 0. Moreover, it return 0 when your statement does not affect any row , for example in DDL execution it may return 0.
