Answer 1

There are two problems with you query.

First, DataBase is a Reserved Keyword, you must escape it with backtick.

String query = "insert into `database` (did,dname,dadress,salary,sex,specialist,`cell#`) 
                VALUES (?,?,?,?,?,?,?)";

Second, the column names must not be wrap with single quotes. because if you do that, it will also generate an error telling you that the column was not found. Only columnNames and tableNames can be enclosed with backtick.
